Product Description

Double roll crusher | roller crusher | roller crusher | toothed roll crusher
The hydraulic roller crusher is mainly composed of roller, roller support bearing, compaction and adjusting device and driving device. The adjustment of the discharging granularity: with a wedge or gasket between the two roller adjusting device, adjusting bolt, wedge at the top of the device when the adjusting bolt will wedge pulled up, wedge rolling activity to the top from the fixed wheel.
[feed granularity] : <40MM.
[production capacity] : 50-800t/h.
[application domain] : hydraulic pressure roller crusher is widely used in mining, smelting, building materials, highway, railway, water conservancy and chemical industry and so on.
[adaptive materials] : widely used in mineral processing, building materials, silicate and ceramic industries.
Product advantages:
Compact structure, strong design, large feeding port. The whole hydraulic roller crusher can be divided into upper and lower parts. The two upper arms are protected by special alloy steel plates, which are mounted on the shelf. The lower part of the heavy cylinder is used to support the main shaft and adjust the position of the spindle so as to control the size of the discharge port.
Hydraulic adjustment system has better overload protection function.
Because of the spindle is supported by the lower oil cylinder, so the spindle and dynamic cone plate lifting together, when mixed iron and other broken objects into the crushing cavity, large crushing force on the moving cone, moving cone fell rapidly, make miscellaneous iron and other objects cannot be broken by crushing cavity as soon as possible, achieve crusher overload protection function.
CLP constant crushing cavity design. CLP means that the performance of the liner is constant. The crushing of the feeding area is almost vertical, and the shape of the broken cavity is almost constant throughout the wear of the entire liner. Therefore, the production capacity of the crusher will not be smaller because of the wear of the lining board, it can effectively reduce the running cost.
Easy to operate and maintain.
All operation and maintenance of the hydraulic roller crusher can be completed from the upper part of the crusher, which makes it easier to operate the crusher and lower maintenance cost.
Working principle: the hydraulic pressure roller crusher is used to crush the material into the crushing zone by using the friction force of the roll, so as to withstand the crushing or splitting of the machine. When used for coarse crushing or need to increase the crushing ratio, it is often used to make teeth or grooves on the roll surface to increase the splitting effect.
Use range of double roll crusher:
This series of double roll crusher for ore dressing, chemical, cement, refractories, abrasives, such as building materials in the industrial sector and finely various kinds of high, medium hardness ores and rocks, especially in the building materials industry production melon meters stone and green bean paste and other products, there are more excellent than general broken mechanical effect.
Two roll crushers should pay special attention to the following items:
1) to strengthen the iron removal work. Non-breaking objects (bits) fall into the double roll and break the crusher, causing a parking accident. Therefore, the iron removal device should be installed before the crusher.
2) the viscous material can easily block the broken space, and should be stopped in the process of handling blockage, and cannot be poked in operation.
3) when the processed materials contain large amounts of large chunks, it is important to note that large chunks of ore are easily extruded from the broken space in case of injury or damage to the equipment.
4) after running for a long time, due to the large wear of the roller surface, it will cause the product granularity to be too fine, and it is necessary to adjust the drainage hole or repair the equipment.
5) strengthen the inspection on the equipment of double roll crusher, lubricate the lubricating parts of the equipment on time and keep the equipment well lubricated.  
The tooth roller crusher is a new product designed and developed by reference to the structure principle of the American crane crusher.
Toothed roll crusher has small volume, big crushing ratio (5-8), low noise, simple structure, convenient maintenance, the advantages of high productivity than now in China (2 PGC toothed roll crusher 1 to 2 times higher productivity), has been broken material granularity and the crushing rate low, easy maintenance, overload protection, safe and reliable, etc.
This tooth roller crusher is suitable for coal, metallurgy, mining, chemical industry, building materials and other industries more suitable for large coal mines or coal preparation plant coal (including waste rock).
The crushing capacity of the toothed roller crusher is large, and the coupling between the motor and the reducer is connected to the hydraulic coupling, which prevents the power overload, the sensor overload protection, and the safety and reliability. The gear spacing hydraulic adjustment, the tooth roller bearing concentrated lubrication. Tooth shape optimization design, pull shear force choice crushing, high efficiency and low consumption, the particle uniform.
My company produces the toothed roll crusher is divided into double toothed roll crusher and four toothed roll crusher two big series, double toothed roll crusher is mechanical spring type (2 PCS), the toothed roll crusher can be respectively according to the material properties of broken and requirements with coarse teeth in the roll or roller, four practical with two double toothed roll crusher toothed roll crusher combination.
The working principle and main structure of tooth roller crusher.
The tooth roller crusher mainly adopts the special wear-resistant gear roller high speed rotation to split and break the material (the traditional toothed roll crusher adopts low speed crushing and crushing), forming the mechanism of high productivity.
The tooth roller crusher is composed of transmission device, rack part, crushing roll, mechanical spring device and linkage mechanism.
