Double Roller Stone Crusher

Production Description of Double Roller Stone Crusher

Double roller stone crusher appeared in 1806, is a relatively old crusher and also called double roll crusher, double rolls crusher, double roller rock crusher. The double roller stone crusher is mainly composed of roller, roller support bearing, pressing device, adjusting device and driving device.

Perfomance of Double Roller Stone Crusher

1. The grinding roller body should be optimized again and doesn't need to be changed for the whole life of the equipment. However, the old type of roller crusher needs to be disassembled and overhauled for replacing the roller after one year of use.

2.A replaceable wear-resistant lining plate is installed on the grinding roller of the double roller stone crusher. It is made of domestic advanced wear-resistant materials, which has the advantages of long service life, not easy to be damaged and convenient maintenance. The continuous service life of a double roller rock crusher can reach more than one year. When the wear is serious, the roller crusher can be replaced by moving the cover. The maintenance quantity is small and the cost is low, which is unmatched by any other type of stone crusher in China.

3.The double roller stone crusher is equipped with a safety protection device. When there is an accident of metal iron pieces entering the crushing cavity, the protective device will work and leak out the iron parts so that the roll crusher will operate normally.

4.The roll gap of the abrasive roll body of the double roller rock crusher can be adjusted arbitrarily between 1mm and 20mm. After the roll gap is adjusted according to the requirements of the crushing particle size, the crushing particle size can be controlled reliably, and all of them are discharged from the bottom of the crushing cavity with ideal particle size.

5.Double roller stone crusher has the advantages of simple and reasonable structure, low operation cost, stable operation, high efficiency and energy saving, high crushing efficiency, and adjustable discharge particle size.

6.The working principle of double rolls crusher is roller extrusion with low speed and high pressure. The materials fall into the crushing cavity vertically from the upper part of the roller crusher and are crushed by the strong pressure generated between the two rollers. Most of the materials have become powder, and a large number of cracks have been generated in the remaining small part of granular materials. In the further crushing process, the energy consumption of crushing can be greatly reduced to increase the output.
