Ultrafine vertical roller mill

SBM Micro Powder Technology Co., Ltd. designs and manufactures high-quality ultrafine vertical roller mills, which can grind any ore materials with a Mohs hardness below 6. Our goal is to “get the maximum benefit with the minimum investment” for our customers.

The key reason why the SBM ultrafine vertical roller mill sells well is that the finished fineness of the ground product is fine, and the finished fineness can be adjusted according to the demand, and the operation is convenient.

What is a ultrafine vertical roller mill?

Ultrafine vertical roller mill is a new type of vertical roller mill suitable for grinding non-metallic ultra-fine powder, which is developed by improving the existing vertical roller mill technology on the basis of absorbing the advantages of foreign ultra-fine vertical roller mill and analyzing the needs of domestic customers.

Independent research and development of Ultrafine vertical roller mill used Adopt multi-head powder separator, SBM classifier perfect solved the particle cutting point height rate of screening questions, compared with the traditional horizontal classifier, fully guaranteed the fineness of finished product can reach 20% ~ 70% (powder size<2um)(Detection machine: Malvern Micro laser particle size analyzer).

After years of material research and development, SBM’s new wear-resistant alloy steel has been successfully applied to roll, ball mill bearing and other wear-resistant parts, which gives wear-resistant parts extremely long service life and prolonging the replacement cycle of wear-resistant parts.

Working Principle

Ultrafine vertical roller mill is mainly composed of motor, reducer, grinding wheel device, roller device, pressure device, powder separator, feeding device, oil station, main engine, electric control system and so on.

1. Grinding wheel device: the main part of rolling material, no power output, due to the friction force in contact with the material and passive operation.

2. Rolling plate device: the grinding area of the material is connected with the reducer and rotates by itself.

3. Pressure device: control the clearance between grinding wheel and rolling disc to ensure the pressure of grinding wheel during grinding.

4. Powder separator: multi-head powder selection structure, the use of rotating centrifugal force principle to achieve continuous production of fine powder screening and filtering work, is a high efficiency, energy-saving powder selection device.

Ultrafine vertical roller mill grinding plate is rotated by the main motor via the reduction gear. Meanwhile, high pressure air enters the mill interior via inlet.

Materials then fall onto the center of the grinding plate in rotation by the screw conveyor feeder. Due to the centrifugal force, the materials evenly move from the center of the grinding plate towards its fringe. While passing across the track in the grinding plate, large blocks of materials are crushed and grinded directly by the grinding roller. The fine particles form the material bed, owing to squeezing, where the inter-particle crushing takes place until grind to the fine powder.

The fine powder continues to move towards the fringe of the grinding plate until they are taken away by strong air flow at the air ring. While the materials along with the air flow pass through the separator located above the grinding plate, the coarse particles return to the grinding plate for re-pulverization due to the action of the rotor blade, the fine particles along with the air flow leave the mill interior and are collected and discharged as finished powder product by the powder collector.

Product Application

Ultrafine vertical roller mill can be widely used in large-scale ultra-fine dry powder processing of non-metallic minerals such as calcite, marble, limestone, dolomite, barite, talc, kaolin, dolomite, wollastonite, gypsum, feldspar, pyrophyllite, etc.
