Vertical Roller Mill Operation

Vertical Roller Mill Operation

Vertical roller mill is Shanghai SBM industrial,in order to solve technical problems about mill with low yield, higher energy consumption.SBM absorb the advanced technology, and combined with years of advanced flour mill design and manufacture their own idea and market demand, after many years design,the improved large grinding equipment has been producted.

Vertical roller mill collection of finely,drying, grinding, choose powder, transmission in a body, cover an area of an area small, simple process, high grinding efficiency, low energy consumption, low noise, large drying capacity, product fineness is easy to adjust, no dust pollution and convenient maintenance, reliable running etc.Especially in the large grinding process, fully meet customer demand, the main technical and economic index reached the international advanced level.Widely used in metallurgy, electric power, cement, chemical, ceramics, non-metallic mineral, water power plant desulfurization, slag, slag, slag, coal, cement, glass, quartz, limestone, and other industries of large-scale material powder grinding and ultra-fine powder grinding.

Products include: suitable for pulverized coal preparation, metallurgy, electric power, cement industry vertical coal mill (medium-speed coal mill);Non-metallic mineral powder grinding is suitable for vertical mill;Suitable for comprehensive utilization of industrial waste gas desulphurization and slag superfine type vertical mill;Applicable to the cement production vertical raw meal grinding, etc.

Vertical roller mill structure:

Vertical vertical roller mill is mainly composed of classifier, roller device, abrasive disk device, pressure device, speed reducer, motor, shell and other parts.Separator is a kind of high efficiency, energy saving powder device.Roller is used to crush materials grinding parts.Mill is fixed on the reducer output shaft, roller compaction is material.Pressure device is for roller grinding pressure parts, rollers to provide enough pressure to crush material.

Roller is a major part to crush grinding material.Which comes in mill bent arm, under the effect of external force, the press on the mill material, in the mill, roller rotates, so that the material being shattered by rolling.

Mill is fixed on the reducer output shaft, the upper millstone to material bed, bed material has a circular groove, the material is in the annular groove is roller grinding.Pressure device is to provide the roller grinding pressure parts, it is composed of high pressure gas station, the hydraulic cylinder rod, accumulator, etc, can exert enough pressure rollers to make the material crushing. Reducer is a major components, transmission power is mill speed reducer output shaft speed.

Vertical roller mill working principle:

Motor rotation speed reducer drive a millstone, through material by the lock feeder wind from the inlet in the middle of the mill, hot air from the air inlet into the ground at the same time.Rotation as a millstone, material under the action of centrifugal force, the mill edge, through by circular groove on the mill roller compaction and crushing, after crushing material on the edge of the mill bring up by the wind ring of high-speed flow, larger particles directly into to grinding mill, material in air through the upper separator under the effect of the rotating rotor, the coarse powder from the cone hopper fall to mill grinding, qualified fine powder with airflow grinding, through collecting dust collecting device, namely for the product, contain moisture materials are in the process of contact with the hot air flow drying, by adjusting the hot blast temperature, can satisfy the requirement of different humidity material, water reach the required products.By adjusting the separator, different products can reach the required thickness degrees.
