China Henan province Zhengzhou city Gongchi Machinery Equipment Co.,

LTD., Specializing in the production of: roll crusher is divided into

two structures of double roller crusher and four roller crusher

crushing equipment.
Roll crusher for roll crusher is mainly composed of the roller, the

roller bearing and compaction and adjusting device and device drivers,

toothed roll crusher is mainly the use of special wear-resistant high

speed rotation teeth roll to split and broken material, form the

mechanism of high productivity, the maintenance of the machine is an

extremely important regular work, it should be in close coordination

with the extremely operation and maintenance, etc.
Roll crusher Roll crusher (for Roll crusher | for Roll crusher |

double Roll crusher) applies in cement, chemical, electric power,

metallurgy, building materials, refractory industries crushing medium

hardness materials, such as limestone, slag, coke, coal, such as Roll

crusher
The crusher, finely homework.
This series of roll crusher is mainly composed of the roller, the

roller support bearings, pressure and adjusting device and driving

unit and other parts.
The working principle of
1, this series of roll crusher is mainly composed of the roller, the

roller support bearings, pressure and adjusting device and driving

unit and other parts.
2. 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, namely two

roller clearance greatens, discharging granularity, when the wedge

downward, activities under the action of the roller in a compression

spring two rounds of smaller clearance, discharge size smaller. Gasket

device is through the increase or decrease in the number of gasket to

regulate the partical size or thickness, when add gasket two roll gap

get bigger, when reduce the gasket two roll gap become smaller, the

partical size.
3. The drive mechanism is made up of two motors, through v-belt

transmission to the Geneva wheel to drive the roller, according to the

relative rotation direction. The broken material, material from the

feed port, through the roller, the rolling and broken, broken after

the finished product out from beneath the chassis.
4, for the sake of safety, transmission parts should be according to

the actual situation to install safety cover.
