1 - 50 T/H Capacity Vertical Roller Mill For Dolomite / Calcite / Marble

Vertical Roller Mill For Dolomite / Calcite/Marble ,1 - 50 t / h Capacity

Description

The selection of high-quality vertical mills for large-scale production of dolomite mines can improve milling efficiency, increase unit production capacity, and help enterprises reap greater economic benefits. Hefei Hengcheng has always been active in the research and production line of vertical grinding machines. In response to the demand of the dolomite ore market, it has innovated and upgraded vertical grinding machines, optimized equipment structural features, improved various performance parameters, and made them better applied to practical production, becoming an ideal standardized dolomite ore milling equipment.

Dolomite ore is a carbonate mineral with a chemical composition of CaMg (CO3) 2 and a crystal structure similar to calcite. According to the difference in composition of dolomite, it can usually be divided into iron dolomite and manganese dolomite, which can be applied in fields such as building materials, ceramics, glass, refractory materials, and environmental protection and energy conservation. It is mainly used as an alkaline refractory material and a flux for blast furnace ironmaking; Production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; And ingredients for producing glass and ceramics.

In the field of large-scale production of dolomite mines, Hefei Hengcheng has taken the lead in creating an ideal vertical grinder that integrates crushing, grinding, grading, drying, and conveying. The system layout is compact, the structural design is reasonable, and the superior drying and dust collection effect eliminates the need for additional equipment, directly reducing the comprehensive investment cost of the enterprise; Adopting a standardized modular pressure device, the production capacity and particle size range are increased by configuring the number of grinding rollers. The single machine production capacity can reach 5-700T/h, which is 5 times that of traditional ball mills. The product particle size ranges from 80 to 600 mesh, which can meet the diversified production needs of customers; Equipped with an advanced PLC electronic control system, with a high degree of automation, the entire process of material grinding is controlled by a microcomputer system, reducing the number of repeated grinding, reducing the damage to the material structure caused by grinding, and reducing the probability of iron impurities, which helps to obtain higher purity dolomite ore powder.

The motor drives the reducer to drive the grinding disc to rotate. Under the action of centrifugal force, the material moves around the grinding disc and enters between the grinding roller and the grinding disc. Under the pressure of the grinding roller, the material is crushed by compression, grinding, and shear forces. The ground powder is blown by the airflow of the blower to the classifier on the upper side of the main machine for screening. The particles that are too coarse still fall into the main machine for re grinding, while those that meet the specifications of fineness flow into the pulse dust collector with the wind, After collection, the finished product is discharged through the powder discharge pipe, and the purified airflow flows into the air blower through the pipeline on the pulse collector.
