Vertical Roller Grinding Mill-Energy-Saving and Efficient Bentonite Vertical Mill

Description

Bentonite is a clay mineral mainly composed of montmorillonite, commonly known as a white earthy block. Using a bentonite vertical mill to grind it to a certain fineness and maintain a certain amount of interlayer water, it has special properties such as plasticity, bonding, suspension, adsorption, and decolorization, and can be widely used in industries such as casting, iron ore, drilling, building materials, papermaking, and particularly, with great practical value.

1. Equipment composition of bentonite grinding machine
The complete set of bentonite grinding machine includes hammer crusher, bucket elevator, storage bin, vibration feeder, grinding machine host, variable frequency classifier, dual cyclone dust collector, pulse dust removal system, high-pressure fan, air compressor, and electrical control system.

2. Working principle: The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.

3. Performance characteristics of bentonite grinding machine
The HVM series bentonite ultrafine grinding machine is a fine powder and ultrafine powder grinding machine produced by our company. It is a base for producing ultrafine powder grinding machines and has advantages compared to many other grinding machine products:
● High efficiency
When the fineness of the finished bentonite powder and the power of the motor are the same, the output of the ultrafine bentonite grinder is more than twice that of the airflow mill, stirring mill, and ball mill;
Long service life of vulnerable parts
The grinding rollers and rings are forged with special materials, greatly improving their durability. When the fineness of materials and finished products is the same, the service life of the vulnerable parts of the bentonite ultrafine grinding machine is 2-3 times longer than that of the impact crusher and turbine crusher, generally reaching more than one year; This type of grinding machine can have a service life of 2-5 years when processing calcium carbonate and calcite;
High safety and reliability
Due to the absence of rolling bearings and screws in the grinding chamber, there is no problem of the bearing and its sealing parts being easily damaged, or the problem of damaging the grinding machine due to loose screws;
High product fineness
The finished bentonite powder processed by this grinding machine can achieve a one-time fineness of D97 ≤ 5 μ M;
Low environmental pollution
The use of environmentally friendly pulse dust collectors and silencers in the grinding machine greatly reduces dust and noise pollution to the surrounding environment.
