Equipment optimization processing to meet processing needs:
In view of the viscosity of magnesium oxide, we have carried out professional treatment and process optimization design for the equipment: the pipeline is sprayed with special substances, and the circulating air of the system is increased to reduce the viscosity of the material; Improve the clogging of the mill.
Ring roller mill, also known as roller press mill (abacus mill), is crushed by multi-layer ring rollers rolling, impacting and grinding. The ring roller mill has a simplified structure, exquisite materials, more durable and easier to use, and can be applied in high fineness and large output.
The ring roller mill adopts rolling crushing and multi-layer rolling methods, and is widely used in high-fine crushing of various non-metallic minerals with Mohs hardness below 6 and humidity below 7%, such as talc, calcite, calcium carbonate, dolomite Stone, potassium feldspar, bentonite, kaolin, graphite, carbon, etc. Widely replaces Raymond mills.
The raw materials are fed into the crushing chamber by quantitative feeding, and the materials are scattered to the periphery of the ring roller under the action of centrifugal force and fall into the raceway of the grinding ring to be crushed, rolled and ground by the grinding roller. After being crushed in the first layer, the material falls into the second and third layers, and after being crushed in the third layer, it is thrown out by the throwing disc, and is sucked into the classifier by the negative pressure of the induced draft fan. Coarse particles are sorted by a classifier and fall back for regrinding, while fine powder enters a cyclone collector or a bag filter to collect gas-solid separation with negative pressure airflow. The material is discharged from the discharge valve, and the air is purified by the dust collector and then discharged through the fan and muffler.

● High powder selection efficiency
The speed of the powder separator is controlled by frequency conversion, and the speed is more accurate; the isolated cyclone powder collector greatly improves the efficiency of powder selection.
● Small footprint
The ultra-fine ring roller mill occupies a small area, which saves industrial land area, reduces the total cost of project investment, and improves customer benefits.
● Highly automated, good comprehensive benefits
The whole production line is highly automated, with high grinding efficiency, more stable operation, reduced maintenance intensity and production costs, high-quality finished products, and good comprehensive benefits.
● Customized solutions to help reduce costs and increase efficiency
Our team has carried out a multi-faceted and thoughtful design for the production line according to the customer’s requirements. The operation planning is simple and reasonable, the number of equipment used is small, the process is smooth, the production line is convenient to operate, and the operating cost is reduced.
● 24-hour continuous production without stopping
The grinding roller bearings and reducer of the main machine are all lubricated with thin oil, which can be used for 24-hour continuous production without stopping. The lubrication system is stable and reliable, and the maintenance is simple.
The equipment is sealed as a whole, and the system works under negative pressure. The finished product is directly sent to the large, finished product warehouse by the gas conveying equipment, without dust spillage, and the production environment is clean, which meets the national environmental protection requirements.
