Applied materials: coal, pebble, limestone, dolomite, granite, construction waste, pebbles, glass, cement clinker, basalt, iron ore, quartz stone, coal gangue, etc. Its advantages: high capacity, ability to handle wet, sticky feeds.
Roll crusher, as one of the most economical and practical crushers, is designed to handle the first and second crushing of friable minerals and stones such as coal, clay, coal gangue, limestone, slag, cement clinkers, and shale, etc.
According to the number of rollers, the FTM roll crushers can be divided into three types: single roll crusher, double-roll crusher, and multi-roll crusher. And the most common one is double-roll crusher.
Roll crusher is applied more widely than other crushers because of its small volume and cheap price. With the adjustable discharging system, it can be used flexibly in coarse and fine crushing processes of the industries such as cement, chemical engineering, electricity, mining, metallurgy, building materials, and others.
Roll crushers can adjust the wedge device between rollers to control the feed and discharge size of the machine. Also, it is equipped with a spring device to protect the crushing machine and avoid shutdown caused by overload and iron passing.
When the adjustable bolt pulls the wedge upward, the wedge pushes the movable roller away from the fixed wheel, then the gap between the two rollers becomes larger, and the discharge port becomes larger, and vice versa.
The gasket device adjusts the size of the discharge by increasing or decreasing the thickness of the gasket. When the gasket is added, the gap between the two rollers becomes larger, and vice versa.
The unique structure of rollers makes selective crushing of the roll crushing equipment. Since minerals fed are crushed along its internal friable crack, the finished products are uniform with the cube shape.
The minerals are crushed under the force of rollers and machine body, and ores smaller than the gap between roller and machine frame (of single roll crusher) or roller (of multi-roll crusher) will pass directly without repeated crushing.
With the supporting CPU, operators can control roll crushing machines and monitor gaps between rollers, and clean up the crushing cavity through the central control room, which will help save energy of 30% to 50%.
The main working parts of the roller crusher is the cylindrical rollers. The rollers are supported by the fixed and movable bearings, and they are relatively rotating which are driven by the motor. The materials are crushed by the friction of the rotating rollers, and the finished products are discharged from the gap of the rollers.
The spring is used to balance the pressure generated between the rolls. If there are non-crushed materials falling between the two rollers, the compression spring of bearings can be pushed to make a large gap so that non-crushed materials can be discharged immediately.
The quality of the crushers has a great impact on its price. The high-quality equipment will cost more in terms of workmanship, technology, materials, etc. Meanwhile, it will have a long service life, low failure rate, and better performance, and bring more profit to investors.

The crushing rolls consist of the roller bodies, complemented with crushing rings or crushing shells. The rolls are secured either with anchor bolts and end disks, or bolted with screws. In order to facilitate maintenance, the crushing roll shafts are arranged in heavy-duty cast steel housings with lubricated, amply dimensioned spherical roller bearings. Materials used are of highly wear-resistant specially cast alloys in order to achieve long lifetimes of parts.
One of the most important materials required for any construction is stone chips. It is used along with cement, steel, and bridge in any and all kinds of construction works. Different sizes of stone chips are required for different kinds of construction works, and one can get the stone crushed into various different sizes like 12mm, 20mm, 35mm, etc. accordingly.
Different kinds of constructions of various things need different techniques and also different sizes of crushed stones. That is why stone chips are essential in the construction of houses, roads, bridges, or any other work. Stone chips also make for a very essential item in many other products that are based on or made from cement. Be it PSC moulds, pre moulded slabs, RCC pipes, beams, frames, or any other cement based product essential for fabrication, and stone chips are needed for them all.
All this makes a stone crusher plant project a great new business venture for young and new businessmen and entrepreneurs. What makes this venture a very amazing one is that the business will flourish for any hard working man/woman because quality stone chips and crushed stones are in high demand and always will be. As the product is so important for all kinds of construction works, good quality crushed stones will remain in high demand till there is construction going on in the world.
All types of construction activities from residential and housing to industrial and business-related all of them require stone chips and use them. Stone chips is use in the production of concrete with all the binding material to make filler for it. A good quality concrete consists of around 70-72% stone chips in its entire volume. Stone chips are the things that influence the quality of concrete and its strength, which means that good quality and a sufficient amount of crushed stones are what will make your concrete good and high quality.
The most in-demand and popular stone chips are of some really good quality black stones. But you can still have an incredibly successful plant even if you dont have black stones available as long as you offer impeccable quality stone chips in your plant. A stone crusher plant can be set up with and according to the raw material available to you and the major commercial centre. You can sell and provide any stone chips from any stones to the market, and as long as it is high in quality, your business will bloom.
In order to find out the total investment required for this new venture, there are a few things that one must look at. To set up a stone crusher plant project, one needs land, and the heavy machinery required to do the work. This is why land and machinerys price makes for the major investment cost to set up a new stone crusher plant. Other than that raw material required by you, manpower and labour, utilities, and other such things make up to become major working capital costs in a stone crusher plant.
So obviously, a high first investment might require to set up a new stone crusher plant. But there are many government schemes which you can now very easily get subsidy for your first capital investment from various banks around you. Under the funding of the project, there must be a percentage of the promoters allocation of the fund. It would be best if you also kept in mind that the Government that provide you with subsidies might also ask you to provide them with a collateral security deposit on the loan amount itself.
The machinery required in any stone crusher plant will be different according to the feed size of the stone that you put into it, the required stone chip size, and also the size of the crusher that you will use. That is why you need t think carefully about your target audience and what type of end product do you want to bring to the market. But there are a few items of machinery that are generally required in all stone crusher plants. They are-
There are two major and most common types of stone crusher plants. A stationary stone crusher plant and a portable or mobile one out of which you can choose which one suits best to all your needs. Stationary stone crusher plants can be used at quarry heads, and the portable ones are best to use at the construction sites.
The first thing that needs to happen is the manual breaking of huge and large stone boulders and rocks into relatively smaller sizes. This smaller stone is then sent to the stone crusher, which then mechanically crushes the entire stone into the stone chip size required by you. A general stone crusher can at any time break and crush a stone size of around 175 mm.
The crushing of stone happens in two different stages. The first stage happens when you manually introduce and feed the 175 mm stones to the crusher, which then reduces it to anywhere around 50 mm stone pieces. Then one can fit the conversion kit to the stone crusher itself, which allows it to crush that 50 mm stone piece to any smaller size from 5 mm to 20 mm. This conversion kit helps you require size of stone chip need for the construction project in progress. The location of unit is a major thing to consider while setting up a stone crusher plant firm or business.
The most important thing to remember while setting up a stone crusher plant project of the firm is to provide the customers with good quality. Fair prices, good quality, and good customer service will make your new stone crusher plant firm a popular one, and you will find great success in the field. There are many ways this new business venture can become a highly successful one, but it requires hard work and determination.
This is a project that is in high demand and will be till there is construction work in progress in the world. In any case, detailed research on the subject, on its workings, requirements, and hard work is essential for this venture to be a good and successful one.

There are many types of crushing equipment used in the industry, and there are many classification methods. Crushing equipment can be divided into: jaw crusher, cone crusher, roller crusher, impact crusher and grinder according to the working principle and structural characteristics.
According to the trajectory of the moving jaw, it can be divided into a simple swing jaw crusher and a complex swing jaw crusher. Jaw crusher, commonly known as "Laohukou", is one of the crushers with a long history and is still the most effective equipment for crushing hard materials.
The cone crusher uses the conical surface of the swing motion to periodically approach the fixed cone surface, so that the product material clamped between the two cone surfaces is crushed and crushed. It can be divided into a gyratory crusher for coarse crushing and a cone crusher for medium and fine crushing.
The working part of the roller crusher is two relatively rotating rollers. The roller surface can have teeth, which is called a toothed roller crusher. It is mainly split and broken and also has squeeze. According to the number of tooth rollers, it can be divided into single tooth roller, double tooth roller and multi-tooth roller crusher.
Hammer crushers and impact crushers are both impact crushers. This type of crusher has a high-speed rotating rotor with an impact hammer. When the material enters the crusher, it is crushed by the high-speed rotating hammer or gets energy from the high-speed rotating rotor, and throws it to the wall of the crusher at high speed or is specially designed. The hard board was crushed.
The grinder is a hollow cylinder with hollow journals at both ends. The material enters from one end of the cylinder and the product is discharged from the other end. The cylinder contains grinding media (steel balls, steel rods or gravel). According to the different grinding media, the grinder is divided into ball mill, rod mill or gravel mill. When the cylinder rotates, the medium is brought to a certain height and falls, which impacts and grinds the material and crushes the material.
