What is Roll Crusher Machine?

Roll crusher is also called double roll crusher, double teeth roll crusher, etc. The surface of the roller crusher is made of high manganese steel, which can stand up to heat treatment.

1.Crushing various rocks

Double toothed roller crusher is generally used for crushing medium-hard rocks with compressive strength of less than 200 Mpa, such as limestone phosphate, basalt, granite, river pebbles, iron ore, gold ore, copper ore lead-zinc ore, nickel ore, asphalt, bricks, cement, and other materials.

2. The first choice for crushing coal

Double toothed roller crusher is a new type of equipment recommended by major coal plants for crushing raw coal, coke, lignite, and activated carbon. lt crushes the coal by squeezing the double toothed rollers and easily removes the materials adhering to the rollers.

The roller crusher has dual functions of pre-screening and crushing. Small and medium-sized materials in the coal mine are directly leaked from the gap between the toothed rollers to avoid reprocessing. The phenomenon of over-crushing is improved.

3.Crushing sticky materials

Hydraulic Roller Crusher

The roller crusher, also known as roll crusher machine, has a wide range of applications across various industries. Some of its key applications include:

Roll Crusher is suitable for River gravel, iron ore, limestone, basalt, quartz, granite and other medium or hard ores and rocks in metallurgy industry, cement industry, power department, construction, phosphate, refractory industry, etc.

Roll crusher machines have several structural advantages that contribute to their efficient operation. These include:

The counter-roller crusher pulls the material on the roller surface into the crushing cavity, so that the material is crushed by the stress mainly caused by squeezing, and is taken out of the crushing cavity by the rotating roller and discharged as the crushed product.

Working Principle of Roller Crusher Machine

The main working parts of the roller crusher is the cylindrical rollers. The rollers are supported by the fixed and movable bearings, and they are relatively rotating which are driven by the motor. The materials are crushed by the friction of the rotating rollers, and the finished products are discharged from the gap of the rollers.

Product Features & Advantage 

① It has a simple and compact structure with small occupation and convenient operation and maintenance.

② The cost is low and the operation is stable, with high energy and crushing efficiency, and adjustable discharge port.

③ It has a light weight, small size, significantly saving investment.

④ The roller crusher is equipped with safety protection devices. When metal pieces enter the crushing chamber, the protective device works and lets the metal leak out of the machine without stopping it.

⑤ The inside is equipped with dustproof board, which has good sealing performance, avoids splashing of fine materials after crushing, with less dust, low working noise,  largely improving the working environment.

⑥ The gap of the abrasive roller can be adjusted arbitrarily between 1mm and 20mm. After adjusting the roll gap according to the requirements, the crushing particle size can be reliably controlled, and all of them are discharged from the lower part of the crushing cavity with the ideal size.

The roller crusher is working in low speed and high pressure with extruding materials which fall vertically into the crushing chamber from the upper part, and are crushed by the strong pressure generated between the two rolls.

⑦ Most of the material has become powdery, and a large number of cracks have been generated in the interior of the small granular material. Thus, in the further pulverization process, the grinding energy consumption can be greatly reduced and the yield can be increased.

⑧ The roller crusher is equipped with a replaceable wear-resistant lining plate which adopts domestic advanced technology, and has the advantages of long service life, easy damage and convenient maintenance.

The continuous service life can be more than one year, and can be easily changed when the wear is seriously damaged. The maintenance quantity is small and the cost is low, which is unmatched by other types of crushers.
