Overview

LM vertical grinding machine driven stand grinding machine is an innovative high-end grinding equipment of our company based on the original grinding machine, combined with the industrial demand, learning advanced grinding technology at home and abroad, and upgrading and upgrading the original grinding equipment.The grinding machine is characterized by high yield, small wear, intelligent operation, convenient maintenance, durability and green environmental protection.Compared with other equipment in the market, it has incomparable technical advantages and cost performance, and is the best choice for large crusher customers in power, construction, mining, stone industry, stone making, rubber, mixing station, paint, environmental protection and other industries.

Features

1、This product integrates crushing, drying, grinding, grading and transportation. The system is simple and compact. It takes up 50% of the floor area of ball mill.

2、Efficient crushing.

3、Internal hot air can directly dry all powders;This feature can not only help investors save the investment cost of dryer, reduce energy consumption.

4、Cage separator and conical rotor separator.

5、By controlling the hydraulic device and rotating lifting arm, roller sleeve and grinding plate can be easily replaced.This saves both maintenance time and labor costs.

Working Principle

The mill roller is driven by the electrical motor through an electrical motor and the material will be fed to the center of the disk from the feeding port via an air- locking feeder and meanwhile the hot- blast air will be blown into the mill through the air inlet. Along with the rotation of the mill disk, the materials will move to the edge of the disk under the action of centrifugal force and grinded and crushed by a grinding roller when they pass through the circular groove on the disk. The crushed materials will be blown up by the vane at a high speed at the edge and the large- sized particles will fall onto the disk to be re-pulverized. The qualified fine particles will be grinded out along with the airflow and the finished products will collected by a dust collecting device. The materials which contain moisture will be dried when they are contacting with the hot airflow. The product can meet the requirements on the materials in different humidity by regulating the hot- blast temperatures as to obtain the moisture and the degree of thickness required by different products can be achieved by regulating the separator.
