New or old, we can keep your Trommel Screen running at full production. We keep a large list of parts in stock. We are able to service your Trommel Screen and refurbish certain parts or the whole plant. Or if you no longer have any use for your Trommel Screen, we can sell it for you.

Our Semi-Static Trommel Screens come in a 6 foot or 8 foot diameter screen setup. The 8 foot diameter setup comes with a larger feed hopper and feed tray. This allows more tonnage per the hour to pass through and be screened by the Trommel. Both the 6 foot and 8 foot diameter setups can have 2 to 6 drum segments installed. Each drum segment allows different sized material to pass through the open slots. Anything that can not fall through the drum segments falls out of the end of the drum. Our Trommel Screens can be installed on to a free stnding steel skid support frame or you may choose to build your own concrete support walls instead. The Semi-Static range can easily be took down and relocated to a different part of your site. If you currently own a Trommel Screen, we can service, provide parts and refurbish it for you to keep your Trommel Screen running like new.

People use screening equipment to separate different grades of material such as soil, gravel, mulch, and sand. These machines work great when they are working with dry material, even if bits and pieces are large in size. A notable weakness, however, is the difficulty that traditional screeners have with wet materials such as moist soil, wet sand, and compost. These substances tend to clump together when they are wet, which reduces the efficiency of the machine. In addition, moist material can clog up the machine and stick to the screen. This can be difficult to dislodge and will cost a lot of time. Fortunately, trommel screen sifters are available to make these tasks much simpler.

A trommel is a screen that is curved into a cylinder. The machine spins the cylindrical screen in order to sort through the material as it is fed through. During this process, the wet material tumbles around. Air is added and the soil, mulch, or sand becomes lighter and drier. The tumbling action also allows maximum contact time with the screen so that the fine material gets through quickly. A trommel screen can sort through dry substances quickly as well, even though it is designed with wet material specifically in mind.

These sifters come in different sizes, but in general they are portable enough to be moved by truck. This is very handy if you need to screen soil or mulch in more than one area of a homestead or if you need to move the machine to a different location entirely. Due to the materials that trommel screens specialize in, they are particularly popular with landscapers and excavating contractors. When things need to get done quickly, you cannot depend on your material being dry enough for a standard screening machine. Every handyman knows the importance of bringing the right tool for the job. The bigger the job, the more important the tool.

Cities can often find a lot of uses for screening machines. Trommel machines are particularly useful because they can handle a variety of tasks with speed. A quality screener pays for itself quickly when there are several tasks at hand. They are a beast that can take on a lot of work, but be sure not to overfill the machine. With a trommel, additional material beyond the designed capacity will only slow things down. The surface area of the screen is the limiting factor, so clogging the center of the rotary with more dirt or mulch will not accomplish anything. These machines are top notch quality, so it is important to remember that they should be allowed to work at their set pace. Even if there is a lot of labor to be done, the trommel will cut through it at a healthy speed, so let it run its course.

Like with many heavy duty machines, it is best to buy a trommel screen directly from a manufacturer. Far and away, this will get you the best price. By cutting out the middleman, you will also avoid all the overhead costs of a separate store and any salesman commissions. You pay the freight costs, but you would be indirectly paying for that anyway. The only issue with dealing directly with the manufacturer is that you need to do a bit of research. Luckily, the internet has made this issue all but disappear. Manufacturers that sell directly to customers have websites that explain the details of their products and provide informative videos and descriptions. By comparing different screeners and companies, you can find the highest quality machines at the best possible prices. If you are fairly good at performing online searches, the entire process will take less than an hour. If you need to sift and sort wet materials, purchasing a trommel machine straight from the manufacturer is the way to go.

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.

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.

Through our worldwide network of branches, our trommel screening specialists supply complete turnkey trommel solutions tailored to your specific process and plant requirements, from engineering and design, through to installation, commissioning, field service and the supply of trommel spares, including screen panels.

Multotecs ongoing research and development and focus on continuous equipment optimisation has resulted in rotary trommel screens that are engineered for maximum impact and abrasion resistance to deliver enhanced screening life that optimises your process efficiency.

Our heavy duty trommel screens consist of the rubber-lined steel frame and replaceable screening surface. Several modifications can be made to this basic trommel screener, including a dual media screen to produce a two-fraction material grading.

When a client requires a new trommel screen, our first step is to determine the main process parameters of your application. There may be a lot of variation in the diameter of the bolt on flange diameter, for example, as it depends on the size of the mill.

The feed end flange is designed to be compatible with the mill or scrubber flange. The flange has a machined face with a compatible bolting arrangement to the mill / scrubber discharge trunnion flange.

The internal diameter of the feed-end flange or feed-end liners is designed to be the same diameter as the mill discharge or mill discharge liners. The trommel feed end liners can also have a slightly larger diameter to create an outwards step to compensate for wear of the mill discharge liners.

Using Finite Element Analysis (FEA) across the complete trommel screen design allows Multotec to calculate the stresses in the structure for a full rotation in order to optimise the fatigue life. The design process adheres to BS 7608:1993 for Fatigue Design Assessment of Steel Structures. Self-driven trommels are also designed by means of FEA and can also be supplied with a feed and discharge arrangement in accordance with specific customer requirements.

FEA is also used to calculate your unique requirement for special cross bracing to counter torsional twisting and account for the ongoing stress placed on the trommel by continuously shifting material loads.

Installed at the end of grinding mills and scrubbers, trommel screening is an efficient, mechanically robust method of screening coarse particles, with a trommel screen machine delivering excellent performance over a long service life.

Trommel screens provide a lower capital cost alternative to vibrating screens, and generate significantly less noise in your plant. Decades of global experience and innovation by world-leading metallurgists and mineral processing engineers at Multotec has allowed an optimum trommel screen design that reduces pegging and blinding and enhances your screening performance.

Our modular polyurethane or rubber panels allow only worn screen panels to be individually replaced, not the whole system. Our unique pins and sleeves or bolt down fastening systems simplify any maintenance requirements.

Multotec provides full engineering support and aftersales services for your screening plant. With preventative maintenance geared towards enhancing longevity of your trommel system, we can completely refurbish worn trommel screens to give them a far greater service life, and reduce capital requirements for your plant.

This includes stripping the rubber lining from the steel structure, prior to visual inspection for wear and non-destructive testing, carried out to determine the integrity of the trommel structure. If your screen is still within specification it can be shot-blasted and re-lined with rubber.

As leading trommel screen manufacturers, Multotec helps customers build larger trommel systems, by overcoming the high wear rates caused by higher peripheral speeds, heavier volumes, and increased flow rates and velocities.
