Introduction to Granite Crusher
Granite crusher (roller crusher) is suitable for coarse and intermediate crushing of brittle block materials in industries such as cement, chemical, power, mining, metallurgy, building materials, refractory materials, coal mines, etc. Its feed particle size is large and the discharge particle size is adjustable. It can crush materials with compressive strength ≤ 160MPa. Especially in the coal industry, when using this machine to crush raw coal, it can be directly crushed as long as it undergoes iron and impurity removal without the need for gangue removal. The crushed material has uniform particle size and low over crushing rate, simplifying the coal preparation process and reducing investment and production costs.

Advantages of Granite Crusher
1、 Easy adjustment of discharge particle size
A wedge-shaped or shim adjustment device is installed between the two rollers of the granite crusher (roller crusher), and the top of the wedge-shaped device is equipped with an adjustment bolt. When the adjustment bolt pulls up the wedge block, the wedge block pushes the movable roller wheel away from the fixed wheel, that is, the gap between the two rollers increases, and the discharge particle size increases. When the wedge block 2 is downward, the gap between the two rollers of the movable roller wheel decreases under the action of the compression spring, and the discharge particle size decreases. The gasket device adjusts the particle size of the discharge by increasing or decreasing the number or thickness of gaskets. When adding gaskets, the gap between the two rollers increases, and when reducing gaskets, the gap between the two rollers decreases, resulting in a smaller discharge particle size.
2、 Wide applicability and good performance
Granite crusher (roller crusher) can be used for finely crushing various high and medium hardness ores and rocks in industrial sectors such as mineral processing, chemical industry, cement, refractory materials, abrasives, and building materials. Especially in the production of products such as sunflower and mung bean sand in the building materials industry, the cement clinker roller crusher has better effects than general crushing machinery.
3、 More crushing and less grinding, high production
Granite crusher (roller crusher) can achieve more crushing and less grinding by reducing the grinding particle size and improving the crushing characteristics of the incoming material; Improve grinding capacity by 15% to 30%, reduce beneficiation costs, and achieve advantages such as energy conservation, consumption reduction, and increased production and efficiency.
4、 Simple structure, easy to inspect and repair
The modular structure of the granite crusher (roller crusher) can be installed separately or in combination according to on-site needs, making it easy to lift and maintain. Standardized module combination gear plates have greater interchangeability and universality, greatly reducing the replacement cycle of gear plates and lowering operating costs.
5、 Low powder yield and good particle size
The granite crusher (roller crusher) adopts a combination crushing method instead of impact and impact crushing, which does not produce secondary crushing phenomenon, so the over crushing rate is extremely low.
6、 Large fragmentation ratio
When a large crushing ratio is required, the cement clinker roller crusher can install an adjustable crushing rod below the two rollers.
7、 Structural standardization
The structure of each type of granite crusher (roller crusher) is standardized, and its structure and length can vary with the required productivity.

Working principle of granite crusher

1. This series of granite crushers mainly consists of rollers, roller support bearings, clamping and adjusting devices, and driving devices.
2. Adjustment of discharge particle size: A wedge-shaped or shim adjustment device is installed between the two rollers, and the top of the wedge-shaped device is equipped with an adjustment bolt. When the adjustment bolt pulls up the wedge block, the wedge block pushes the movable roller wheel away from the fixed wheel, that is, the gap between the two rollers increases, and the discharge particle size increases. When the wedge block is lowered, the gap between the two rollers of the movable roller wheel decreases under the action of the compression spring, and the discharge particle size decreases. The gasket device adjusts the particle size of the discharge by increasing or decreasing the number or thickness of gaskets. When adding gaskets, the gap between the two rollers increases, and when reducing gaskets, the gap between the two rollers decreases, resulting in a smaller discharge particle size.
3. The driving mechanism is composed of two electric motors, which are transmitted to the pulley through a V-belt to drag the rollers and rotate them in opposite directions. When crushing materials, the materials are crushed through rollers from the feeding port, and the crushed products are discharged from under the chassis.
4. For safety reasons, the transmission part should be equipped with a safety cover according to the actual situation.Technical parameters of granite crusher

Granite crushing production process
The granite used in the granite production line is first uniformly fed into the jaw crusher by a vibrating feeder for coarse crushing operation, and then sent to the roller crusher for secondary crushing of the stone material. If you need small particles such as stones, configure the number of layers of the vibrating screen according to the required size of the stones. If you need two types of finished stones, then configuring a two-layer vibrating screen is sufficient. If used for sand making, it needs to be further crushed into ultra-fine particles. By using a sand making crusher, 0-5mm sand can be obtained. Then, by using a sand washing machine to clean the mud and some impurities in the sand, clean sand and gravel can be obtained.
Note: The crushing equipment used for the second fine crushing in the granite crushing production line can be determined based on various factors such as customer material characteristics, crushing fineness, production capacity, etc. What we recommend here for everyone isimpact crusher、Roll Crusher、four-roll crusherThese three types of crushing equipment. Customers can choose according to their own granite crushing production line needs.
