Vertical Spiral Mill Ore Grinding Mill PLC Control 6mm Feed Size
1. Product use and characteristics of vertical spiral mill
Vertical screw mill is mainly used in the crushing and grinding of metal ores, the crushing and deep processing of non-metallic ores, the comprehensive utilization of low-grade minerals, the extraction of useful elements in tailings and other mining industries, powder metallurgy, mechanical alloying, metallurgical raw material processing , metallurgical waste slag utilization, cemented carbide production and other metallurgical industries and other industrial industries. It is a device that grinds ore or other materials of a certain particle size into a finer particle size, and is a kind of ultra-fine grinding equipment.
The vertical screw mill uses the method of stirring to achieve the purpose of grinding and refining particles. Under the agitation of the agitator, the medium ball and the mineral material in the mixing tank do multi-dimensional circular motion and self-rotation motion, and the gravity generated by the medium ball and the mineral material and the centrifugal force generated by the rotation are comprehensively used, and the medium balls, the mineral material and the medium Impact, friction and shearing are produced between the ball and the mineral material, and the mineral material is deformed, fractured and finally crushed under the action of momentum and impulse to achieve the ideal particle size. Compared with the traditional ball mill under the same power, the energy saving is 30% to 50%. The smaller the product particle size, the more obvious the energy saving effect. The maximum input particle size can reach 6mm, and the minimum output particle size can reach 0.02mm.

3. Technical characteristics of vertical spiral mill(ore grinding mill)
(1) Vertical spiral mill is mainly composed of transmission part, frame part, spiral part, inspection door, rough classification equipment, spiral installation tool, motor, reducer, etc., with simple structure and convenient maintenance;
(2) The frame is lined with wear-resistant and corrosion-resistant rubber, and a grid lining or magnetic lining is installed to protect the frame and prolong its service life;
(3) The installation cycle is short, generally 2~4 weeks to complete the installation of the body;
(4) The overall force of the mill is balanced, the foundation has no additional load, and the foundation design is simple;
(5) There is no internal impact during operation, and the loss of grinding media is small;
(6) The vertical screw mill has two feeding methods: upper feeding and lower feeding, which can be freely selected according to the process conditions;
(7) Using PLC control, it has the functions of sound and light alarm, fault diagnosis, etc., and realizes the integration of electromechanical and hydraulic control.
