High pressure roller mill is widely used in the processing of 280 kinds of materials in mining, metallurgy, chemical industry, building materials and other industries. It is suitable for grinding non-flammable and explosive materials with Mohs hardness less than 9.3 and humidity less than 6%.

Application

High pressure roller mill is mainly suitable for processing various non-flammable and explosive mineral materials with humidity less than 6%. It is widely used in metallurgy, building materials, chemical industry, mining, highway construction and water conservancy industries. It is used for processing quartz, feldspar, calcite, limestone, talc, ceramics, marble, granite, white stone, dolomite, bauxite, iron ore, coal and other materials. The adjustable fineness is between 0.613 mm and 0.033 mm.

Components and parts

The whole set of high pressure grinding equipment consists of main engine, reducer, analyzer, pipeline device, blower, dust collector, jaw crusher, bucket elevator, electromagnetic vibration feeder, electronic control system, etc.

Working principle

In the main machine of high pressure roller mill, the grinding roller assembly is suspended on the grinding roller hanger through the cross-arm axle. The grinding roller hanger is fixed with the spindle and the relief tool holder. The pressure spring is pressed on the outer end of the cantilever of the grinding roller bearing chamber. The cross-arm axle is used as the fulcrum point to force the grinding roller to press tightly on the inner surface of the grinding ring. When the motor drives the spindle to rotate through the transmission device. When moving, the shovel blade mounted on the shovel holder rotates synchronously with the grinding roller, which rotates around its own axis while rolling in the inner circle of the grinding ring. The higher the speed of impeller, the finer the separated powder. In order to ensure that the mill works under negative pressure, the increased air flow is discharged into the bag filter through the residual air between the fan and the main engine, and then discharged into the atmosphere after being purified.

Advantages and features

1. Unique design. In the grinding chamber of the main engine, a pressure device of 1500kg-2000kg was designed on the upper part of the plum blossom rack. Under the same power, the output was increased by 10-30%, the grinding pressure of the grinding device was increased by 800-1500kg, and the fineness of the finished product was up to 1000 meshes.

2. Material applicability is strong. It can be applied to all kinds of materials with Mohs hardness below 9.3.

3. Roller grinding device adopts high quality and efficient processing technology, overlapping multi-stage seal ensures good sealing effect.

4. The replacement cycle of roller and ring is long, and the disadvantage of short replacement cycle of vulnerable parts of centrifugal mill is eliminated.

5. The lapping device adopts overlapping multi-stage seals with good sealing performance.

Technical data

As a manufacturer, our newly designed high pressure roller mill is more practical, the hardness and wear resistance of grinding rolls, grinding rings and shovels are improved, the service life is generally increased by more than two times, the production cost is reduced, the equipment runs smoothly and without abnormal phenomena, the sealing and lubrication performance of special lubricant paste is good, and the oil-saving is increased by 60%. Performance, operation rate is over 95%, output per hour is increased by over 30%, and economic benefit is good.
