Product Introduction

Double toothed roller crusher: a crushing equipment mainly used for crushing hard materials such as ores, stones, etc. The double toothed roller crusher has two relatively rotating toothed rollers, and the material is crushed between the toothed rollers.

At present, the most advanced crusher technology in limestone mine is to use jaw crusher for primary crushing and double-geared roller crusher for secondary crushing. Compared with other secondary crushers, the lump forming rate of the output of the double-geared roller crusher is increased by 15% - 25% (3cm ~ 9cm blocks), which can improve the economic value. According to the different hardness of limestone, the double-geared roller crusher has many advantages such as high reliability, strong stability and good performance on saving cost. Our gear roller is made of Babbitt high-strength wear-resistant alloy, and its service life is 2-3 times longer than that of common material. According to the current customer use, the spare parts need to be replaced after 3-5 years of use. The replacement cycle of spare parts is long and the continuous production is reliable.

Double-geared Roller Crusher is a mature and advanced classification crusher, which has been finalized after more than 10 years of continuous research and innovation. It can adapt to all kinds of harsh environment and can strictly guarantee the product granularity, high block rate, very low over crushing rate and high material roundness after crushing. It is mainly used in coal, coke, gangue, limestone, calcium carbide and other materials under the primary crushing, secondary crushing operation, which is widely used in coal, building materials, metallurgy, chemical industry and other industries.

Scope of application

The machine is suitable for building materials, cement, chemical, refractory, coal, mineral processing, sinter, silicate, glass, abrasives, ceramics and other industrial sectors, can handle a variety of medium and high hardness (160Mpa below) ore and rock crushing and fine crushing. Roller crusher can handle materials are: steel slag, river pebbles, pebbles, calcite, quartz, glass, marble, bentonite, bluestone, steel slag, limestone, weathered sand, granite, basalt and so on. Especially in the sand making industry and building materials industry, it has a good effect on small materials, and has great advantages compared with other crusher equipment.

Working principle

The roller crusher mainly uses two sets of independently driven rollers to break materials through the extrusion and grinding force generated by relative rotation. The material falls between the two rollers through the feed port, and the finished product falls naturally after being crushed by the pair of rollers. When encountering hard or unbreakable materials, the roller can automatically retreat under the action of the hydraulic cylinder or spring, so that the gap between the two rollers increases, and the hard or unbreakable materials naturally fall to ensure that the machine is not damaged. By adjusting the pressure of the hydraulic cylinder or spring, the pressure between the two rollers increases or decreases to control the size of the finished product, and the greater the pressure, the smaller the finished product.

Performance characteristics

1. Equipped with roll crusher on the sand production line, the production capacity of the sand making equipment can be fully utilized, which can generally increase the output by 30%-40%, and the total energy consumption can be reduced by 20%-30%. For sand making systems with production capacity requirements, the installation of a rolling machine can significantly save investment.
2. Simple structure, small space, easy operation and maintenance, less dust, low noise, environmental protection and pollution-free.
3. Long service life, low operating cost, wear parts roller skin with new wear-resistant materials, can greatly improve the service life, reduce later replacement costs.
4. The roller crusher is equipped with safety protection device. When metal filings enter the crushing chamber, the roller bullets open, the iron filings leak out, and the equipment runs normally.
5. The roll gap of the roll crusher can be arbitrarily adjusted between 1-20mm, and after adjusting the roll gap according to the requirements of the crushing size, the finished particles can be effectively controlled, and all materials are discharged from the bottom of the crushing chamber with the ideal particle size.
