Working principle of drilling grade bentonite Vertical grinding mill

In the course of oil and gas drilling, mud is used to cool the bit, remove debris, protect the wellbore and balance the ground pressure. Bentonite is an ideal material for drilling mud with good dispersion and large amount of slurry. The most important technical requirements of bentonite is used as drilling mud for its suspension properties, wet screening analysis and moisture content. The important role of bentonite in drilling makes it very large amount. It is understood that an average of one well is need to use about 8 tons of bentonite. The preparation of high quality bentonite, efficient milling equipment is an inevitable choice. Guilin Hong Cheng has accumulated rich manufacturing experience in bentonite processing field, made a more mature and efficient bentonite powder selection scheme which can provide better bentonite grinding process.

Bentonite vertical grinding mill working principle: motor drive reducer drives the grinding plate rotation, the material under the centrifugal force to move around the grinding plate into the grinding roller and the grinding plate, under the function of grinding roller pressure, material was been extrusion, grinding and shearing force and crushed, grinded powder flow by the blower airflow to the main mill at the top of the classifier for classifying, the coarse powder granularity still fall into main mill for re-grinding, specified powder are collected by pulse dust collector, purification air flush flow into the atmosphere after meridians through the pipe collector.

As a high-quality grinding mill, Hong Cheng grinding mill not only has excellent characteristics of high efficiency and high capacity, but also integrate drying, grinding, classifying, transportation as a whole, mainly consist of main mill, feeder, classifier, blower, pipeline device, storage hopper, electric control system, collection system, with the increase of production capacity, the equipment can be correspondingly increase the number of grinding roller, different types of products to form a variety of capacity, greatly meet the needs of different project.
