Present Situation And Development Prospect Of Large Hydraulic Roller Crusher

Last Update:2020-05-08 13:06:32

This kind of crusher is also called the counter roll crusher. Because of its special performance, it has been playing a leading role in the industrial sectors such as cement, metallurgy, chemical industry, electric power, coal and so on, which have strict requirements on the particle size, particle type and powder passing phenomenon of products after crushing. In the process of production, it uses the friction force of the roller surface to bite the material into the crushing area. The special wear-resistant roller rotates at high speed to crush and split the material, forming the mechanism of high productivity. The discharge particle size can be adjusted by wedge or gasket device. The former is to change the gap between the two rollers by lifting the wedge, so as to change the size of the discharge. The latter is to adjust the size of the discharge particle by increasing or decreasing the number or thickness of the gasket. When the gasket is increased, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge particle size becomes smaller. This kind of adjustment is precise and easy to control, which has been adopted by many large-scale roll crushers.

In the aspect of using status, due to the problems of traditional design, the production capacity of the equipment is low, the quality of the equipment is large, the ability of crushing large materials is poor, so it is not suitable for crushing hard materials, so the application scope is limited. With the development of production and construction as well as the continuous improvement of scientific and technological level, the roller crusher has new improvements and development in structure and crushing mechanism, such as the extension crusher, roller crusher, toothed roller crusher, hydraulic roller crusher, etc., which makes the application scope of roller crusher expand continuously, creating energy-saving and consumption reducing for building materials, coal, chemical industry, mineral processing and other industries At the same time, it brings higher economic benefits to enterprises.

In recent years, the development of counter roll crusher abroad is faster than that in China, and the types are also very complete. According to the number of rollers, roller crusher can be divided into four types: single roller, double roller, three roller and four roller. According to the shape of roll surface, it can be divided into smooth roll, toothed roll, grooved roll crusher, counter roll crusher, etc. As far as its structure is concerned, most of them adopt new technologies and structures such as automatic moving roller structure, hydraulic adjustment, oil-liquid control system, etc. The structure and control system adopted by each manufacturer are different, and the unique features can be compared according to the pictures of roller crusher and relevant technical parameters when purchasing. Shanghai Shibang is also a mining machinery manufacturer that keeps up with the development of the industry. Its crushing equipment has been sold to more than 100 regions at home and abroad.
