ez-409: compact trommel screener by ez-screen

The constant tumbling action stirs up material over and over, fluffing it, adding air to lighten it, and keeping it in contact with the rotating mesh longer. This action allows more material through faster and easier. Which makes the trommel the screener for landscapers, excavating contractors and municipalities.

So what makes the EZ-409 the better choice over other trommel screeners? One big reason is the small price. The price is low because we sell direct, one to one. No sales force. No inventory. No showrooms. No commissions.

Another reason is a whole lot of reasons: like a baked on powder-coat finish; vulcanized conveyor belts; a durable 50-HP Deutz diesel engine; auxiliary hydraulics for adding another stockpiling conveyor; and hydraulic jacks at the discharge end for proper tilt angle to adjust the material flow speed.

Like all EZ-Screen machines, the EZ-409 is easily trucked from job site to job site. Set up is quick, too. Working with a to 1 loader, the EZ-409 is designed, engineered and manufactured to provide outstanding production for specialized screening operations. With its chain-driven heavy-duty rotating drum, the slipping that occurs in wet materials on wheel-driven competitive trommel screeners is eliminated.

Trommel screen is a kind of screening equipment commonly used in the gold dressing process. Through the continuous rotation of the trommel screen, large pieces of waste rock can be thrown out, thus saving the time of sorting operation and greatly improving the efficiency of the next sorting operation of alluvial gold ore.

The placer gold ore is similar to the placer tin ore, deposits in the hillside, the river bed, the lake coastal place, forms the certain enrichment, it has the industrial mining value, is called the placer gold deposit. In general, the monomer dissociation degree of alluvial gold ore is high, only the trommel screen is used to screen out the large piece of gold-free waste rock, and the gold deposit is deposited on the sticky gold cloth, and a good index can be obtained.

The drum device is tilted and mounted on the rack. The motor is connected by a reducer and a drum device through coupling to drive the drum device around its axis. When the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is flipped and rolled, so that the qualified material (sieve product) is discharged through the outlet at the bottom of the back end of the drum. Unqualified materials (sieve products) are discharged through the outlet at the end of the drum.

trommel screen vs vibrating screen, which is better? - jxsc machine

trommel screen vs vibrating screen, which is better? - jxsc machine

In the mineral processing area, the trommel screens(aka. Rotary drum screens) and vibrating screens are both widely used screening & classification equipment. But whats the difference between the trommel screens and vibrating screens, and how to choose the most suitable screens for your mineral processing application? Or even how should we choose the right screening equipment for specific mining conditions?

Thorough we all may know that they are both are widely used screening equipment, but the different working methods and principles also mean the difference in output, as well as the types of materials suitable for screening processing.

Vibrating screens are screened using the exciting force generated by a vibrating motor and belong to vibrating screens. Commonly used mine vibrating screens include circular vibrating screens and linear screens.

The trommel screen is another screening form. During the screening process, the equipment will not vibrate, but generally, the motor and reducer drive the drum to rotate through the bearing. The material in the drum passes through the screen from high to low due to the rotation of the drum. And it is successfully screened out, so the trommel screen belongs to a type of rolling screening.

trommel screen: It is a cylinder. The outer surface of the cylinder uses one or more layers, or several sections of screens to increase the screening specifications. The volume of the trommel screen is generally large, mainly including motors, reducers, drum devices, screens, and machines. It is composed of a frame, a sealing cover, and an inlet and an outlet. A steel ring must be added to the drum device to prevent the trommel screen from deforming.

The roller device is installed on the frame obliquely. The motor is connected with the roller device through a coupling through a reducer, and drives the roller device to rotate around its axis. When the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is turned and rolled. The qualified materials (products under the screen) are discharged through the outlet at the bottom of the rear end of the drum, and the unqualified materials (on the screen) The product is discharged through the discharge port at the end of the drum.

Using the vibration motor as the vibration source, the material is thrown up on the screen while moving forward in a straight line. The material enters the inlet of the screening machine evenly from the feeder, and produces several kinds of screens through the multi-layer screen. The upper and lower objects are discharged from their respective outlets.

The screen surface is fixed on the screen box, and the screen box is suspended or supported by springs. The bearing of the main shaft is installed on the screen box and is driven by the pulley to rotate at high speed. The eccentric counterweight plate is installed on the main shaft and generates centrifugal inertia force with the rotation of the main shaft, so that the screen box forms an approximate circular orbit vibration.

The trommel screen can be divided into single-layer, double-layer and three-layer vibrating screens according to the number of layers of the screen. This vibrating screen is also similar, according to the number of screen surface layers can be divided into single-layer, double-layer, three-layer and four-layer vibrating screen.

The vibrating screen is a screening equipment with a vibrating motor as the vibration source, so the screening accuracy is high. The trommel is a high-output screening equipment, and the screening accuracy is not as high as the vibrating screen.

For the trommel screen, the material is turned over and rolled in the drum, so that the material stuck in the sieve hole can be ejected to prevent the sieve hole from being blocked. For the circular vibrating screen, the material moves in a parabolic circular trajectory on the screen surface, so that the material is dispersed as much as possible to improve the materials bounce force, and the material stuck in the screen hole can also jump out, reducing the hole blocking phenomenon.

Vibrating screen and trommel screen have their own working methods and screening principles. Some raw materials can be screened through them. However, for different sites and different material requirements, suitable screening machines should be selected to achieve better screening results.

This do-it-yourself compost sifter pairs nicely with a community-scale composting operation found at community gardens and farms. For a basic primer on aerated static pile composting check out my posts Aerated Static Pile Composting, Design & Build of Solar Powered Aerated Compost 3-Bin, and Supplies for a Basic Aerated Static Pile Setup.

Ive worked at a number of scales in the composting industry, including Fleet Manager for a large mulch and compost producer where I maintained the repairs for over $8 million in equipment (tub grinders, trommels, wheel loaders, semi trucks, etc.). Additionally, I spent my youth around farms and industrial machinery so designing and building this trommel came with fewer road blocks than others might have. Thats why Ive put this article together, to help the gardens and micro-enterprises develop a sifter, more specifically a trommel that fits your needs.

Ive wanted to build a trommel since I first strained my back screening compost over a sheet of hardware cloth. In many gardens screening or sifting is the overlooked part of the equation. Id spend hours over the course of a growing season making wonderful compost, but when it came time to sift compost for the garden I didnt have a good solution.

Equipment manufacturers in the compost industry cater to medium and large scale compost and soil producers. This makes good sense since the economics of composting generally requires large equipment. Granted there are smaller machines, such as the Sittler, that are made for landscaping services, soil blending businesses, farms, and so on, but they can carry a price tag that is difficult for a small start-up.

I started by researching DIY trommels and collected notes on design considerations. Having managed a fleet of equipment which included (8) 40 foot long trommels I knew that this project would be cutting out most of the nice features of trommels used in the industry. No conveyors, no input hopper, no brush to clean the screen and definitely no powder coated steel.

Popular mechanics ran a great article on building a trommel. I recommend you read it if youre serious about building one. That article also referred to some YouTubers (David Waltmans version and Geoff Babcocks version) with their iterations of trommels. I pulled screenshots of all the designs I liked and noted how certain areas were handled. I also looked at several videos I had of a Jet worm harvester to figure out a good rpm.

The design of the trommel drum is the most challenging part of the design/build process. The cylinder/drum/trommel is the part that does the work. It needs to be suspended in the frame while also having as little rolling friction as possible. Since it is going to be tilted it needs to be held in place to prevent it from sliding out as it rolls.

For my purposes I wanted the machine to have easily replaceable screens. I had two ideas for doing this and chose a method that I had seen in the past. I found a make a clamp kit online. The kit comes with pipe clamps and 50 feet of stainless steel banding. I used these to cut custom length pipe clamps which wrap around the screen and clamp the screen onto the aluminum ring.

Since the mesh does not act as structure (in some designs the hardware cloth is used to support itself) I needed to figure out a way to create a roundish structure without special metal fabricating equipment. To make the trommel round I went with the obvious solution, bike rims. I used the bike rims to fit 3 inch wide aluminum bands to the inside of the rims.

I used 27 bike rims that I picked up from a non-profit bike shop. If you look for rims made by Araya which were prevalent on late 70s through 80s road bikes youll be good. My trommel has five 27 Araya rims. They are close to the same inner diameter.

To bend the aluminum bands I used two 4x4s in the voids of two CMU blocks. This was a total guessing game. I just bent the metal a small amount at a time until I got a slow arc. Then repeated until it was almost a ring. I used a hack saw to trim the ring down to size.

I drilled through the rim and into the aluminum bands and used low profile bolt heads to bolt the two together. The 3 inch wide band creates a flange on both sides of the rim. This gives space to mount the screen. It also gives a place to put support wheels. The bike rim gives roundness and prevents the trommel from sliding off.

The rings are connected to four aluminum angles that run the full length of the screen. To help the screen do a better job of screening material I used 1 angle aluminum to carry material up the screen and drop it as the drum rotates.

The trommel is the core of the machine. I designed around it. I knew I would be using hardware cloth as my screen. They come in three widths at my local hardware store, 2 feet, 3 feet and 4 feet. The width of the screen informs the length of the trommel, which tells me which length lumber I should use for the frame.

To reduce wood waste and save time, I designed the frame to use dimensions that come standard from the lumber yard. I went with a low height, with the intention of using plastic tubs under the screen. Some gardens may want to fit a wheelbarrow or gang of wheelbarrows under the trommel, plan for this in advance by ensuring youll have the clearance needed for a wheelbarrow to roll under the trommel. I added corrugated metal as a chute to send compost fines down into the tubs and reduce the mess. This is an area I would change as I mention below under Improvements.

Finally, the drive mechanism. The trommel needs to rotate. There are several ways to add power transmission to the screen. You can use the support wheels to drive the drum, you can use a belt drive or chain drive, or you can put a gear on the outside diameter of the screen.

Another key component to the trommel is final RPM. How fast should it spin? I looked at trommels spinning on YouTube and counted their RPM. Somewhere between 10 and 20 RPM seems like the best fit. Mine is a little on the slower side at 12ish RPM. Im ok with that because I have the occasional worm that I dont want to hurt if it goes through the screen.

To reduce the RPM of my 1725 rpm 1/4hp motor I used belts and pulleys. There are calculators online that will help you figure out your speed reduction. Just hit up Google and ask for pulley calculator. To figure out the length of belts to use, check Google for v-belt calculator. An online calculator will ask you the distance from center point to center point of each pulley. It will also ask for pulley diameters. It will tell you the length belt to use!

The motor is attached to the top of the frame. It has a diameter output shaft. OnMcMaster-CarrI purchased two 1- diameter pulleys, a 10 diameter pulley, a 12 long D-profile steel shaft, and two pillow block bearings for shaft. The pillow block bearings are mounted to aluminum to reduce binding between the bearings.

To drive the compost trommel I originally intended to run the belt between two bike rims. When I tested this out it slipped and couldnt turn the drum. So I put the belt in the groove of the rim and it worked like a charm.

I bought some replacement electric cord at the hardware store and ran it to a plastic, weatherproof junction box. Inside the box is a typical light switch which can handle the amperage of the motor. I used weatherproof cord grips to keep the elements out of the box. The cord is clamped to the frame, which ensures it wont get wound up in the moving parts.

Hey, I cant complain. I built this trommel for under $500. It works well and it eliminates a bottleneck in the garden. Ive been using a screen on the first section and screen on the second section. The trommel screens about 2 cubic yards of input volume in an hour (depending on how dry the compost is). Finally, I can swap out screen sizes with relative ease.

To serve many industries and applications, McLanahan Rotary Trommel Screens are offered with various types of screen media that have a variety of aperture sizes depending on the application requirement. For units that are larger than 10' (3m) in diameter, McLanahan performs a finite element analysis of a unit prior to manufacturing to ensure the optimal design strength.

As the cylindrical drum of a Rotary Trommel Screen rotates, raw feed material is lifted on shelves until it nears the top of the drum. Material then falls, tumbling onto other material at the bottom of the drum. This action helps to break down softer fractions, as well as separate different types of materials. As the tumbling continues, smaller size fractions filter through holes in the screen plating, while larger material continues along the length of the cylinder to discharge at the end.

The tumbling action of the Rotary Trommel allows accurate sizing and separation that is beneficial for a variety of customers, including those looking to upgrade metallics after mass-burn solid waste incineration, to reclaim wood chips in sewage sludge composting, for accurate size separation of difficult-to-screen materials in municipal solids waste and resource recovery, and to separate and wash ores, rock and other fine materials.

You should know your feed material bulk density, the material particle size feed distribution, the tons per hour feed solids capacity, a process flow diagram showing equipment location of required unit in your processing plant, the separation or cut point(s) and the moisture content.

Proficient in both wet and dry applications, McLanahan Rotary Trommel Screens utilize a continuous tumbling action to size and separate feed material in the municipal waste, industrial and mining industries. McLanahan Rotary Trommel Screens are manufactured to be perfectly concentric machines that produce the material you need for many industries and applications.

what is trommel screen and how does trommel screen work | m&c

Trommel screen, or rotary screen, is a kind of mechanical screening machine which is widely used in the separation operation. It controls the material separation by the particle size, and the separation precision is high. The cylinder of the trommel screen is generally divided into several sections, depending on the specific situation. The mesh holes are arranged from small to large, and the mesh hole diameter on each section is the same.

When the material enters the drum screen, due to the inclination and rotation of the roller device, the material on the screen surface will turn over and roll, so that the qualified material will be discharged through the outlet at the bottom of the drum, and the unqualified material will be discharged through the outlet at the end of drum.

1. It is used for sand screening in sand plant; 2. Used as sand screening machine to screen sand and stone; 3. Used as gold washing equipment for screening and cleaning sand, stone and gold; 4. Used for screening mineral materials in gold boat.
