Ore Grinding Mill Large Mediumless Autogenous Mill And SAG Mill
1. Luo mine development design AG Mill | SAG Mill of ore grinding mill technical features are:
(1)The transmission forms of drum mill include edge flyer, center drive, multi-point mesh edge drive and other transmission types; Drive form has asynchronous motor + reducer + pinion + big gear and synchronous motor + air clutch + pinion + big gear;
(2) Generally, the support mode of two-end static and dynamic pressure bearings is adopted. Completely cLuoed self-aligning 1200 line contact 'rocker type' bearings are adopted. Single slide track, double slide track static and dynamic pressure support or full static pressure support are also adopted.
(3) Large open gear using the American AGMA standard design, equipped with a reliable seal gear cover, glycerin automatic spray lubrication device;
(4) The cylinder is the key part of the mill, and the finite element analysis is carried out by the computer to ensure the reliability of its use;
(5) Large and medium mills are equipped with slow driving devices;
(6) Large and medium mills are equipped with high and low pressure lubrication stations;
(7) Control and protection system using PLC control.

3. Luo mine AG Mill | SAG Mill advantage of ore grinding mill features:
Since the mill | semi autogenous grinding machine is the core of iron ore, non-ferrous metal ore dressing process equipment. Compared with the traditional crushing grinding equipment, Luo mine AG Mill | half since the grinding machine has the technological process is simple, save for two period of crusher and screening equipment), saving investment, short construction period, the advantages of simple operation, has been more and more recognition and use of the related enterprises at home and abroad, has a very broad prospects for development. The biggest feature of autogenous mill is that it can feed raw ore from stope or coarse crushed ore directly into the mill. Usually minerals are fed into the mill rod according to a certain proportion of grain size. The self-grinding machine can grind the material to -0.074mm at a time, the content of which accounts for more than 20% ~ 50% of the total product. The crushing ratio can reach 4000 ~ 5000, more than ten times higher than the ball and rod mill. Autogenous mill is a new type of grinding equipment which has both crushing and grinding functions. It uses the grinding material itself as the medium, through the mutual impact and grinding effect to achieve grinding, automill hence the name. Autogenous mill is also called no media mill.
