HCH ultra-fine ring roller mill is a new type of ultra-fine grinding mill equipment developed by Guilin Hongcheng with many years of production and research experience. It has comprehensive mechanical crushing properties such as rolling, grinding and impact, and is a truly efficient and energy-saving ultra-fine crushing equipment, especially suitable for deep processing of non-metallic minerals. This equipment HCH1395 is certified by China Calcium Carbonate Association as an energy-saving and consumption-reducing equipment in the field of ultra-fine processing of calcium carbonate in China. HCH ultra-fine ring grinding mill is a new type of high and fine crushing equipment. The product fineness can be adjusted between 325 mesh and 2500 mesh as required, and the product fineness can reach D97<5um at one time. The grinding mill has small floor area, strong integrity, wide use, simple operation, convenient maintenance, stable performance and high cost performance. It is an energy-saving high fine powder processing equipment.
It can be used for ultra-fine grinding mill of various non-metallic minerals such as limestone, talc, calcite, calcium carbonate, dolomite, potassium feldspar, bentonite, kaolin, fluorite, etc. with Mohs hardness below 7 and humidity within 6%.
Primary processing D97 ≤ 10 μ M fine powder, and - 3 µ m fine powder accounts for about 40%, with a large specific surface area; It not only has the advantages of high efficiency and low consumption of high-speed impact crusher, but also has the fineness close to that of air mill.
The particle size is uniform and fine, and the fineness of finished product can be easily achieved between 5-38 μ M can be adjusted arbitrarily, and products with different fineness can better adapt to market demand and improve enterprise competitiveness.
Pulse injection type dust cleaning method is adopted, and compressed air is used to clean each filter bag separately to prevent the filter bag from clogging due to long-term powder backlog. The dust collection efficiency is above 99.9%, effectively ensuring dust-free operation in the workshop.
The grinding roller and grinding ring are made of special wear-resistant steel, and the service life is improved. The base of the main engine adopts the integral casting structure, which not only ensures the structural strength, but also has good shock absorption performance.

1. Crushed into materials smaller than 10mm by jaw crusher, lifted to the storage hopper by bucket elevator.
2. Then the feeder is fed into the main machine cavity for grinding quantitatively, and the grinding roller installed on the rotary table rotates around the central shaft. Under the action of centrifugal force, the grinding roller swings horizontally outward, which makes the grinding roller press the grinding ring tightly, and the grinding roller rotates around the grinding roller pin at the same time. Through the gap between the grinding roller and the grinding ring, the material is crushed and ground due to the rolling of the grinding roller. The grinding roller is divided into four layers (HCH780 is a three-layer arrangement), and the material is crushed through the grinding roller and the grinding ring in turn.
3. The ground powder falls onto the chassis due to gravity and is blown to the classifier above the main machine for screening under the air flow of the blower. If the fineness is too coarse, it will still fall into the main machine for regrinding, and if the fineness is qualified, it will flow into the pulse dust collector with the wind.
4. After collection, the product is discharged through the discharge valve, and the purified air flows into the blower through the upper residual air duct. The air circuit circulates, except for the positive pressure from the blower to the grinding chamber, the air flow in the other pipes flows under negative pressure, and the indoor sanitary conditions are excellent.
Along with the rapid development of powder processing industry, the requirement of powder equipment is being higher, equipment types are being wider, and there are more professional equipment aiming at certain material.
