Crusher Introduction
Roller press, also known as extrusion mill, rolling mill, is the international mid 80' s developed new energy-saving grinding equipment, With an alternative high energy consumption, low efficiency ball mill pre-grinding system, and reduce the function of steel consumption and noise . It is applicable to the new plant construction, also can be used for old factory technical renovation and to make ball mill system, 50-110% increase in production. After the extruded material in the feeding cake 0.08mm fines accounted for 20-35%, accounted for 65-85% less than 2mm. The internal structure of small particles due to crushed and filled with many small cracks, significant improvement in grindability. Roller surface thermal welding, wear-resistant layer of maintenance more convenient.
To solve customer’ s Worries of roller machine, our company and famous research institutes cooperated to establish a roller press roller surface, vertical mill disc roller surfacing Research Center, enables customers to use the product after the repair service is firmly guaranteed.
Structure
The roller press is the axis, main frame, feeding device, driving system and hydraulic system, lubrication system, cooling system, detection system and electronic control system,
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.
Technical Feature
●effective extrusion materials: powder more than content.
●use of advanced domestic welding technology, a unique roller surface is welded to the roll surface technology longer life, up to more than 8,000 hours.
●system is stable and reliable operation, extrusion roller adopts steel forging, the bearing capacity of the whole is large.
●unique bearing structure design, there are four row cylindrical roller bearings and thrust bearing combination structure, effective solution to run in a variety of defects.
●safety sensitive hydraulic system: professional design, the hydraulic oil cylinder imported products, adjusting function perfect and reliable, and easy maintenance.
●advanced automatic control system: adopting Siemens PLC center controller, automation stronger.
● nimbly adjusted the feeding system, using electric actuator feeding device, easy operation and production.
●flexible torque support: ingenious cross shaft structure torque support so adjustment performance better.
