For the roller crusher, the roller crusher or the roller crusher is a relatively old-fashioned crushing device. After numerous upgrades and modifications, the manufacturing process is more mature. The structure of the device is simple, the phenomenon of excessive pulverization is small, the tooth shape, size and arrangement on the roll surface can be changed according to the nature of the material, and the medium and hard ore can be medium and finely crushed, for example, the crushing type is usually used in a sulfuric acid plant. The machine crushes the pyrite ore once, so that the diameter reaches 20~30mm, and then enters the double roll crusher for secondary crushing, so that the ore diameter reaches 5mm or less, and the requirements of the boiling furnace are reached. The roller crusher can be used for fine ore crushing various high and medium hardness ores and rocks in the industrial sectors such as mineral processing, chemical, cement, refractory materials, abrasives, building materials, etc., especially in the construction materials industry to produce melon stone and mung bean sand. The product has more excellent effects than the general crushing machine.


8. Adopt automatic oil supply system, extend the service life of the bearing, reduce the daily maintenance work intensity, 2 model parameters of 2LF and FP powerful graded roller crusher. Note: With the long-term upgrade of the product, once the model parameters have any changes, Subject to the actual connection, > Roll Crusher > High Purity Quartz Sand Crusher [Product Price]: 10,000-10,000 [Production]: 2-140 tons / hour [feed size]: ≤ 150 Millimeter [discharge size]: ≤ 2-50 mm [Special use range]: Double roll crusher is also called double roll crusher. Roller crusher is suitable for feeding grain size up to 80 mm, specific finished grain size. For fine crushing operations of 50-20 mm, such as artificial sand making of pebbles and construction waste, mining of fine iron ore, quartz stone, and crushed raw materials in the ceramic industry, our company has accumulated sufficient experience in producing roller crushers.

In order to adapt to different product particle size requirements and crusher "over-iron", the center distance of the two rolls has to change, and the two crushing rolls have to rotate synchronously. In order to adapt to this situation, the roller crusher produced in the early stage mostly uses a single-motor long-tooth gear transmission. The disadvantages of this type of transmission are: small displacement of the center distance, difficulty in manufacturing the gear, severe wear of the gear, and even toothing. That is, each motor drives a roller through a belt or a speed reducer, so that a pair of long-tooth gear transmissions can be removed. However, two speed reducers must be equipped, which is costly. In addition, since the movable bearing needs to move, the tension of the belt drive changes accordingly; if the reducer is driven, the universal joint must be installed to allow the shaft to move horizontally with the roller without affecting the normal operation of the crusher. For the fine broken double roll crusher, when driving with a single motor, a pair of car tires can be used instead of the long tooth gear. In fact, this is a friction drive that changes the gear mesh drive to a pair of tires.


Its structure is simple to build. It mainly uses extrusion to pulverize the material. The material has uniform particle size, no dust pollution on site, excellent running performance and small land area. It is suitable for feeding particle size close to 80 mm and product size is 50-20 mm. The fine crushing operation, the pair of roller crushers are suitable for crushing cement, chemical, electric power, metallurgy, building materials, refractory materials, limestone and other medium-hard materials, as well as slag, coke, coal and other material fragments, between the two rolls Wedge or gasket adjusting device, the top of the wedge device is provided with an adjusting bolt. When the adjusting bolt pulls up the wedge, the wedge pushes the movable roller away from the fixed wheel, that is, the gap between the two rollers becomes larger, and the discharge granularity becomes larger. When the wedge is downward, under the use of the compression spring, the gap between the two wheels of the movable roller becomes smaller, the discharge granularity becomes smaller, and the gasket device is adjusted by generally increasing or decreasing the number or thickness of the gasket. The size of the discharge size, when the gasket is added, the gap between the two rolls becomes larger, and when the gasket is lowered, the gap between the two rolls becomes smaller.
