The Application of Vertical Roller Grinding Equipment, Vertical Roller Mill Equipment:
Vertical Roller Grinding Equipment, Vertical Roller Mill Equipment is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Mohss hardness under six, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite and vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rock phosphate, kalium ore, pumice, etc., totally more than 100 kinds of materials.
Vertical Roller Grinding Equipment, Vertical Roller Mill Equipment mainly consists of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
Working principle of Vertical Roller Grinding Equipment, Vertical Roller Mill Equipment:
After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, edge of then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe. When the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers. The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the air flow 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 an 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.

Application of vertical roller grinding mill equipment: Vertical roller grinding mill equipment are suitable for huge capacity producing, widely used in grinding non-flammable and non-explosive materials under 9.3(the Moh's hardness), such as quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, especially for slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc. Advantages of vertical roller grinding mill equipment: 1. Grinding mill equipment in the market designed as a cement grinder and not a modified raw mill 2. Simple layout and fewer machines in the mill circuit ensure high run-factor and low maintenance costs 3. Roller and table profile improve operating stability and reliability 4. Special design features for iron removal during grinding minimize wear 5. Optimal wear protection on all internal surfaces extends lifetime 6. Flexibility to operate with reduced number of rollers guarantees long-term availability 7. Segmented roller wear parts made of the hardest possible material without the risk of cracking; very suitable for hard facing 8. High grinding efficiency: save 20~30% power consumption compared with the ball mill. With the increasing of moisture content, it can save more and more electricity. Working Principle of Vertical Roller Grinding Mill Equipment: The grinding disc is driving by motor through reducer. The material falls to grinding disc from the feed opening. The materials are driven to the edge of disc by the centrifugal force and crushed into fine powders by rollers. Then, the hot air from the nozzle take the fine powder to high efficiency classifier. The qualified powder is taken by the air to the powder collector to be collected, while the unqualified powder is sent back for regrinding.

Vertical roller mill roller body wear Reasons: 1. Subject to frictional pressure between roller, material reaction force, friction between material and roller liner 2. The mutual effect of the material grinding angle on the shear stress of the grinding roller, the hydraulic system pressure of the roller mill and the apparent compressive stress of the vertical mill Fault: Once there is a matching clearance, impact collision will occur between the body and the lining, which will increase the wear between the body and the lining. In severe cases, the lining will crack or even break, causing the lining to fall off, the machine is damaged, especially the deceleration. Damage to the machine, causing a vicious incident. Solution: Developed countries such as Europe and the United States use polymer composite materials for rapid repair of vertical roller wear, among which the Fushui Blue series is relatively mature. The material is satisfactorily solved with its excellent mechanical properties and good plasticity. It not only prolongs the service life of the equipment, improves the productivity, but also avoids the secondary possibility of the problem, and avoids the additional downtime of the shutdown, and escorts the safe and continuous production of the enterprise. Vertical roller mill wear chamber wear Reason: 1. There is a gap between the bearing and the bearing chamber 2. Bearing heating will lead to bearing sintering Solution: 1. Traditional soldering brush plating method, there are certain drawbacks: repair welding will cause thermal stress, bearing material damage, severe deformation or even break; brush plating pollution is heavy, and coating thickness is limited, application Subject to greater restrictions. 2. The processing of polymer composite materials can ensure the matching of the repaired parts and the matching parts to the utmost extent, and avoid the secondary wear caused by the increase of the gap.
