Do You Have a Clear Recognition to High Pressure Grinding Mill?

High pressure grinding mill is mainly made up of the mainframe, separator, blower, finished powder cyclone collector, bag filter and connecting pipes, etc. According to users’ need, the mill can also be equipped with accessory equipments like crusher, bucket elevators, hopper, electromagnetic vibrating feeder and switch box, etc.

The high pressure grinding rolls, frequently known to as HPGRs or roller press, consists from two paint rollers with similar dimensions, that are rotating against one another with similar circumferential speed. The special feeding of bulk material via a hopper creates a material mattress between your two paint rollers. The bearing models of 1 roller can move linearly and therefore are pressed from the material mattress by springs or hydraulic cylinders. The demands within the material mattress are larger than 50 MPa. Generally they achieve 100 to 300 MPa. With this the fabric mattress is compressed to some solid volume portion in excess of eighty percent.

The purpose of the powder making machine is to grind materials in the fields of building materials, mining, metallurgies and chemical industry. The materials should be non-flammable and non-explosive. Examples of the materials are: quartz, feldspar, barite, fluorite, dolomite, garnet, carborundum, bauxite, zircon, marble, calcite, iron ore, rock phosphate, slag, ceram, gold mine and coal slack and so on(400 kinds of materials). The materials should have the hardness less than 9.3 in Moh’s scale and humidity less than 6 percent. The granularity of the end products can be changed from 30 to 425 meshes.

The roller press includes a certain resemblance of roller crushers and roller presses for that compacting of powders, but purpose, construction and operation mode will vary. Extreme pressure causes the contaminants within the compressed material mattress to fracture into finer contaminants as well as causes micro powder machine fracturing in the grain size level. In comparison to superfine mill HPGRs are achieving a 30-50 % lower specific energy consumption, although they aren’t as fashionable as ultrafine mill being that they are a more recent technology. An identical kind of intermediate crusher may be the edge runner, featuring its a circular pan with several heavy wheels referred to as mullers rotating there material to become crushed is shoved beneath the wheels using attached plow rotor blades.
