introduction

Roller is used in roller press.Roller press is the grinding equipment of brittle materails,apt to grinding cement clinker ,granulated blast furnace slag ,cement raw material(limestone,sandstone,shale and so on),quartz sand ,iron ore etc .

 

Roller press Working principle

The main working parts of roller press is fixed roller and activities of the roller, driven by the motor reducer mainly as a relatively low-speed rotation, when the materials continuous and dense to feed between the two rollers, the hydraulic system, through the cylinder, and roller bearing hundreds of tons of pressure to pass to the roller between the material, the material through the high-pressure extrusion, so that particle size decreased, the powder content of less than 0.08mm to reach 20-40%, less than 2mm of material to reach 60% -70%, and after squeezing in all the materials present in a large number of cracks, so that material in the grinding process when the next one, the required energy consumption drastically reduced. All materials in the pure to be crushed under high pressure, then through the classification, the small particles directly into the mill, coarse particles return to Roller Press.
 

features and performance

1.The hard surface welding technology can service a roller welding service life more than 8000~12000 hours

2.The bimetal centrifugal casting hard surface technology, low cost and price, short maintenance cycle, the service life long (above 35000 hours)
