Roll Crusher

Introduction

Roll crusher is also called double roll crusher, roller crusher, double roller crusher, smooth roll crusher and toothed-roll crusher, which can crush adhesional wetting materials. The machine has strict requirements for particle and shapes, so it is widely used in chemical, coal, coking and so on.

Toothed-roll Crusher

Toothed-roll crusher is applied to coal, metallurgy, mining, chemical industry and building materials, especially to the large-scale coal mine or coal cleaning plant. The machine features screening and crushing, adopting overload protection to ensure long-running.

Notices

(1) Generally, crushing ratio of roll crusher is less than 10. So, if the crushing ratio is bigger, you can choose classified crushing. You should use the machine in accordance with the principle of the maximization of system benefits.

(2) If hard object is stuck in space between the two rollers, the roller surface will be worn. In order to protect the equipment and increase comprehensive benefits, you’d better install an iron separator on the belt of double roll crusher. By this way, you can reduce damages to the roll crusher and increase working efficiency. If you have any questions in your production, please leave a message or send an email to crusher@hxjq.com.

Features

Double roll crusher has the following advantages:

(1) The price of roller crusher is relatively lower than other crushers.

(2) A dust shield is installed in the inside of double roller crusher, so airtightness has been improved enormously. During the crushing, the crushed fine particles which never splash out of the closed trough. By this way, you can improve working environments.

(3) Smooth roll crusher is equipped with security defense measures. If there are small metal particles in crushing cavity, they will outflow. Toothed-roll crusher has so excellent security function that it can service for long time. The machine is the best choice for your investment.

Principle

As the rollers of the teeth roll crusher is smooth, it has not only crushing function, but grinding function. After the materials go into the crushing chamber of the machine, under the driving force of the rotating roller, the materials will be pushed to be space between the two rollers. At the same time, influenced by the squeezing, cutting and grinding force of the rollers, the materials will begin to break. The broken small-sized particles will be thrown to bottom of the machine through the gap between the two rollers along the tangent line of the rotation of the rollers. The materials bigger than the gap will continued to be crushed to small particles.
