Bentonite Processing Flow Introduction

2021-04-08

As environmental protection has become a major problem in industrial development, bentonite is used as an adsorbent for harmful substances, a clarifier for turbid water, a sealant for radioactive waste and toxic materials, a waterproofing agent for polluted water, sewage treatment agents, washing aids, etc. , The role of environmental protection is becoming more and more obvious, and the market demand has been rising in recent years. In addition, the application of bentonite in petrochemical, light industry, and agriculture fields is also very important.

1. Sodiumization stage: Most bentonite in nature is calcium-based bentonite, and calcium-based bentonite has worse performance than sodium-based bentonite.

2. Drying stage: The sodiumized bentonite has a higher moisture content and needs to be dried to a lower moisture content through a dryer.

3. Grinding stage: the dried bentonite is crushed to the ore that meets the feeding requirements of the mill and is lifted to the storage hopper by the elevator, and then fed to the main machine of the mill by the electromagnetic vibrating feeder evenly, in the grinding cavity To grind.

4. Classification stage: The ground material is classified by the classifier along with the system airflow, and the unqualified powder is classified by the classifier and then returned to the main machine grinding cavity for re-grinding.

5. Powder collection stage: The powder that meets the fineness enters the powder collection system through the pipeline with the airflow, and the gas and powder are separated. The finished powder is sent to the finished product silo by the conveying device, and then is packed by a powder tanker or an automatic baler.
