Double roll crusher is suitable for metallurgy, building materials, refractory materials and other industrial sectors broken, higher hardness of the material. The series of roll crusher is mainly composed of the roller, the roller support bearings, compaction and adjusting device and driving unit and other parts.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.3, driving 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.4, for the sake of safety, transmission parts should be according to the actual situation to install safety cover.

Double roll crusher is also called double toothed roll crusher, When it works , We should pay special attention to the following:

1. To strengthen the inspection of double roll crusher, the lubrication part of the equipment on time to go, keep equipment good lubrication condition. Working principle on the roll crusher, double roll the relative rotation between the 2 rounds of ore is divided into two roller, because of friction, ore has been subdivided into the space between the two rollers. In the squeezed and broken. Broken material is according to its own weight. From the discharge gap between the two rollers. The minimum distance between two roll crusher is the width of the discharging mouth, crushing material; the roll crusher is decided by the width of the discharging mouth of the largest size.

2. To strengthWhat we should pay attention to when double roll crusher worksen the work to iron ore. The broken content (qian primary content) fall into the can damage between double roller crusher, as a result causes parking accident. So in front of the breaker shall be installed in addition to iron plant.

3. After double roll crusher (http://www.sell-crusher.com/) run a long time, due to the roll surface wear larger, cause fairly granular product, then pay attention to adjusting the row ore mouth or on equipment maintenance.
