Bentonite Vertical Grinding Mill - Customized Bentonite Grinding Mill 20-325 Mesh Powder Production

Description

Choosing a suitable bentonite vertical mill requires comprehensive consideration of material characteristics, production requirements, equipment performance, and cost-effectiveness. Here is a step-by-step guide to help you make scientific decisions:
1. Clarify the characteristics of bentonite
physical property
Low hardness (Mohs 1-2 grade): requires lower rolling force, but requires anti sticking rollers
High moisture absorption (10-15% moisture content): The grinder is required to have drying function
Strong adhesion: Need to optimize the anti blocking design of the grinding disc
Chemical Type
Sodium based bentonite (easily expandable): It is necessary to control the airflow temperature inside the mill (≤ 200 ℃)
Calcium based bentonite: requires higher rolling pressure

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.

Re:The data based on Mohs'hardness 3-4 material
The product fineness can reach 10 um(1250 meshes)

4. Core advantages
High energy efficiency: 30-50% more energy-efficient than traditional ball mills, with lower power consumption.
Fineness adjustable: By adjusting the speed of the roller and classifier, the fineness of the finished product can be controlled (such as 200 mesh drilling grade, 325 mesh coating grade).
High humidity adaptation: can handle raw materials with moisture content ≤ 15% without pre drying.
Environmentally friendly and low-noise: Fully enclosed system, dust emission<30mg/m ³, noise ≤ 75dB.

5. Typical applications
Drilling mud: Production of API standard sodium/calcium based bentonite powder.
Casting sand binder: fineness of 200-400 mesh, improves the smoothness of castings.
Cat litter/adsorbent: Rapid prototyping of coarse particles (20-40 mesh).
Activated clay: Ultra fine grinding (800-2500 mesh) used as a decolorizing agent.

6. Bentonite Pulverizer Vertical Mill Selection suggestions
Raw material characteristics: Sodium based bentonite (soft) can be selected with low-pressure grinding rollers, while calcium based bentonite (hard) requires high-pressure machines.
Fineness requirement:
Coarse powder (20-200 mesh): choose vertical mill+dynamic classifier.
Ultra fine powder (800 mesh+): requires a secondary classification system (such as a vortex air classifier).
Automation: PLC control system is recommended to achieve remote adjustment of roller pressure and feeding amount.
