Applicabilities
G series high pressure grinding rollers are suitable for fine and ultra-fine crushing of materials with a compressive strength not exceeding 250MPa and humidity below 8%.
Featured by simple structure, reliable performance and low over crushing ratio, these rollers are applied in the sand-making industry and useful for adjusting machined sand fineness modulus.
The materials can be put into production by high pressure grinding rollers only after irons and impurities are removed from them.
Working Principle
The high pressure grinding roller is mainly composed of two rollers which rotate in opposite directions.
The materials enter the two highly wear-resistant rollers with the same size through the feeding device. Press the materials into compact pies, which are crushed into particles with requisite size and discharged through a hopper. In the next step, the material pies are further dispersed or ground into powder.
Product Features
Hydraulic Protection System
The hydraulic system makes it more convenient and easier to adjust roll gap while protecting safety of the whole machine;
High Yield And Low Energy Consumption
The productivity of grinding system increases by 20% to 30%, and power consumption declines by 15% to 35%. Energy consumption is reduced by more than 20% as a whole. Hence, the economic benefits are substantial.
Occupation Of A Small Area
With compact structure and high reliability, the roller occupies a small area and can be flexibly configured.
Longer Service Life Of Roll Surface
The roll surface of the high pressure grinding roller is made of alloy steel embedded with hard alloy studs or cast high manganese steel. This significantly extends service life of the roll surface, which is up to more than 20,000 hours at maximum;
High Environment-Friendliness
The use of roller cover reduces dust pollution and increases environment-friendliness;
Low Maintenance Cost
The simple and reliable structure makes it convenient to replace parts and accessories. It reduces maintenance costs.
