Raymond mill and ultra-fine grinding mill are all milling equipment, but they have their own characteristics. According to customer feedback, we have analyzed the characteristics of these two mills, so that everyone can choose the right equipment.

Raymond mill

The structure of Raymond mill is mainly composed of main engine, analyzer, fan, finished cyclone separator, fine powder cyclone and air duct. The Raymond mill powder is milled by circulating air. After the material is crushed, it is shoveled by a blade, and then the powder is lifted, and the air is blown to the cyclone through the blower, and the fineness of the powder is passed through the disc grading wheel. Make an extension. Raymond mill mainly processes fine powder with a fineness of 40-600 mesh. It belongs to general-purpose equipment. The processed materials mainly include limestone, barite, calcite, potassium feldspar, talc, marble, cement, phosphate rock, gypsum, glass, etc. Up to 280 kinds of minerals, chemical, construction and other industries friends can choose this general Raymond mill equipment if they need the material size of 40-600 mesh.

The ultra-fine grinding mill mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
When the grinding mill is at work, the main bearing and each dial are driven by electromotor of main equipment through reducer, and all the grinding rollers are rolling in the ring channels driving by dial through plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers. Then the materials fall into multiple layers and to be crushed and ground continuously to micro powder.
The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the airflow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end.


Here to remind everyone that the above two types of milling equipment, although the main features are not the same, but the main role is to grind, due to the mechanical construction principle of the equipment, they are grinding machinery, during maintenance All relevant models of grease and oil are required for maintenance, which is beneficial to the long-term stable operation of the equipment.
