Product details
Product Features
The three ring medium speed grinding machine is a common stone equipment widely used in the grinding and processing of mineral products and materials in metallurgy, building materials, chemical industry, mining and other fields. The processing fineness can be freely adjusted between 325 mesh and 3000 mesh, and it has become an important material ultrafine powder processing equipment and other raw material deep processing machines, which is of great significance for the development of modern high-tech industries. The three ring medium speed grinding machine is the core product of the grinding production line, mainly suitable for grinding materials of mineral products such as metallurgy, building materials, chemical industry, and mining. It can grind quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, iron ore, copper ore, phosphate ore, iron oxide red, zircon sand, slag, water slag, cement clinker, activated carbon, granite, garnet, iron oxide yellow, soybean cake, fertilizer, compound fertilizer, fly ash, bituminous coal, coking coal, brown coal, diamond sand, chromium oxide green, gold ore, red mud, clay, kaolin, coke, coal gangue, porcelain clay, blue spar, fluorite, bentonite, and vermiculite. Rhyolite, pyrophyllite, shale, purple sandstone, green mudstone, laminated rock, basalt, gypsum, graphite More than 100 types of non flammable and explosive mineral materials, including silicon carbide, with a Mohs hardness below level 6 and a humidity of 6%. The particle size of the fine powder produced by the three ring medium speed mill can be adjusted between 325-3000 mesh, and the output can reach 0.5-12 tons per hour.

The working environment of the three ring medium speed mill
1. Cleaning the equipment: After long-term operation, the grinding machine is prone to dirt that needs to be cleaned. During the cleaning process, high-pressure and high-temperature water guns should not be used to rinse, especially the electrical parts, which should not be washed with water to avoid electrical burnout.
2. Selection and replacement of oil: When selecting fuel oil, attention should be paid to the properties of the fuel oil. The commonly used fuel oil is diesel, but it should be noted that diesel with a freezing point higher than or equal to the ambient temperature should not be used. Generally, diesel with a temperature 5 degrees lower than the ambient temperature should be selected, such as -10 #, -20 #, -35 #, etc. When cleaning, it is also necessary to thoroughly clean the fuel system, and at the same time, check whether the fuel pump is normal to eliminate potential faults. Cleaning the fuel system is also to ensure that fuel oil can be added to keep up with the operation of the equipment during startup. For the replacement of lubricating oil or grease, attention should be paid to the equipment's use of lubricating oil, and whether replacement is necessary should be determined based on the amount used.
3. Maintenance of components: During the operation of the grinding machine, each component has different temperatures according to its work content. There is a cooling system in the equipment. During maintenance, attention should be paid not to allow sediment in the water tank of the cooling system. If it is found, it should be removed in a timely manner, and the water temperature in the water tank should not be too high or too low. Antifreeze should be added to the water tank.
Working principle
The main motor of the three ring medium speed grinding machine drives the spindle and each layer of turntable to rotate through the reducer. The turntable drives dozens of ring rollers to roll and rotate in the grinding ring raceway through the column pin. Large pieces of material are crushed into small particles by a crusher and then sent into a storage bin by an elevator. The electromagnetic vibration feeder evenly sends the material to the middle of the upper turntable. The material disperses towards the circumference under the action of centrifugal force and falls into the rolling track of the grinding ring, where it is pressed, rolled, and ground by the ring rollers to be pulverized. After being crushed layer by layer, the material falls into the second and third layers. The suction effect of the high-pressure centrifugal fan draws external air into the machine and brings the coarse powder that has been crushed in the third layer into the powder selection machine. The vortex flow generated by the rotating worm wheel inside the powder selector causes coarse particles to fall back and grind again, while fine powder enters the cyclone powder collector with the airflow and is discharged as finished product through the discharge valve at the bottom. The airflow with a small amount of fine dust passes through the pulse dust collector and is discharged through the fan and muffler.
