Introduction to toothed roller grading crusher

Gear roller grading crusher is a new concept of gradingcrusher，

It is completely different from traditional toothed roller crushers that rely on impact and extrusion to crush materials. Instead, it selectively crushes materials with different particle size compositions, and uses the combined force of shear and tension to achieve material crushing. Due to the use of low speed and special tooth shape, there is less over crushing and oversize of materials. The toothed roller grading crusher has the characteristics of high crushing strength, large processing capacity, less oversize and over crushing, and can handle wet and viscous materials. It is also equipped with an automatic control device, which can be easily integrated into the centralized control of the entire plant.（Gear roller grading crusher

The toothed roller grading crusher is mainly suitable for coarse and intermediate crushing of brittle block materials in industries such as coal mining, power, mining, metallurgy, and chemical engineering. Only some toothed roller grading crushers have a feed particle size of ≤ 600mm,

Allow small quantities up to 800-1000mm, with discharge particle sizes up to 150mm, 200mm, 300mm, etc; The feed particle size of the toothed plate toothed roller grading crusher is ≤ 300mm, and a small amount is allowed500mm， The discharge particle size includes 30mm, 50mm, 80mm, 100mm, etc., which can crush coal and medium strength rocks. If the system takes effective measures to remove iron and wood, the raw coal does not need to be treatedPre screening and manual selection for direct crushing can simplify the coal crushing process, reduce the height of the plant, and decrease the construction investment and production costs of coal preparation plants and power plants.

Working principle of toothed roller grading crusher

From the analysis of mineral physical properties, the compressive strength of minerals is much greater than their shear and tensile strength. Data shows that the ratio of compressive strength to tensile and shear strength of rocks is approximately 10:1. Therefore, under the action of tensile and shear forces, materials are more prone to breakage. Gear roller grading

It is based on this principle that after the mixed material enters the crusher, the material is discharged between the two teeth and the comb shaped plate on the side wall. Therefore, the product is controlled by this gap after crushing, and there will be no oversized particles discharged. Qualified particles in the feed

Grade products are quickly discharged after entering the machine and are no longer subject to crushing effects. Therefore, the powder production rate in the product is much lower than that of conventional crushers. Unqualified materials are stuck between two toothed rollers and subjected to shear and tensile forces

It is easy to break when passing through the toothed roller. The machine shows good screening effect and particle size control, and the product particle size is uniform. Therefore, the machines in production showed good performance

The machine is named a grading crusher because of its granularity control function and certain grading function.
