Product description

Raw materials for the mining, aggregate and mineral processing industries are usually larger than what they can use directly or sell to other companies. Once the raw materials are collected, harvested or mined, they need to be reduced in size to make them more marketable. Roll crushers can effectively reduce the size of bricks and concrete. Its crushing action can handle rocks around 8cm and can crush materials to 0-5mm. This makes processing more efficient and easier. If you want smaller raw materials, you need to use a Bricks and Concrete Crusher (roll crusher).

What a Bricks and Concrete Crusher does

The main unit of an industrial roll crusher is equipped with two rollers that rotate in opposite directions. The two rollers squeeze each other together to crush the material. The raw materials are fed into the crusher. Many production lines have more than one type of crusher. This is because heavy crushers (such as jaw crushers) are designed to handle the largest pieces of rock. Secondary crushers (such as cone crushers) break these fragments into finer materials. After the tertiary crushing (roll crusher) stage, the smaller fragments are fed into a screening machine or sorting machine for further processing.

Where a double roller crusher is used

Many industries use industrial crushers. Quarrying, mining operations, construction, demolition, and recycling are the major industries that use this heavy equipment. Some of the end products produced by large industrial crushers include certified coarse aggregates for road building, site construction, and pipeline laying projects, as well as rock salt for icy or snowy roads, and glass for re-melting and recycling into new products.

Sand Production Application

In sand production lines, the double-roll crusher functions as a sand-making machine, offering advantages such as no wear parts, low maintenance costs, adjustable sand particle size, high yield rate, and excellent sand particle shape. It is widely used in the sand-making industry.

Mineral Processing Crushing Applications

In the mineral processing industry, double-roll crushers or high-pressure roller mills are employed for fine crushing operations. Positioned upstream of ball mills, they can reduce 2-3 cm ore particles to less than 1 mm, significantly enhancing the operational efficiency of mineral processing ball mills and boosting overall production productivity.    

The Gravel sand making machine uses rollers to perform crushing operations. The material enters between the rollers from the feed port and crushes the river pebbles through extrusion. There is a certain gap between the two rollers. The larger the gap between the two rollers, the larger the material discharge particle size. Under the action of the compression spring, the smaller the gap between the two rollers, the smaller the material discharge particle size. By changing the adjustment gap, the material discharge particle size can be controlled.
