Product Introduction:

Double roll crusher (also known as roll crusher), is available for industries, such as ore dressing, chemical, cement, refractory, abrasives and building materials etc. It can finely crush the ore, rock and refractory material with high and medium hardness. Roll crusher makes more excellent effect especially in refractory material and mining. In recent years, it is widely applied to industries like steel grit.

Double roll crusher


1. Crushing material fineness can be adjusted.

2. Safety and reliability.

3. Stable performance, low running cost, simple and convenient maintenance.

Operating Principle:

This series of double roll crusher is mainly composed of the roller, the roller support bearings, pressure 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, 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 particle size or thickness, when add gasket two roll gap get bigger, when reduce the gasket two roll gap become smaller, the particle size. 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. When crushing materials, materials from the feed port are crushed by rolling compaction. And the crush materials discharge from chassis.
