1 Effect Working Conditions
A: a rate is not normal, improper adjustment, short positions operating state occurs, and part of direct friction ball striking cylinder liner is formed of two-body wear, this case liner and the ball of fragmentation, wear a substantial increase in opportunities, is a very bad (nasty) (liè) mode of operation. The ball mill differs depending on the mine mode, can be laminated and overflow type. The ball mill can be divided into a short cylinder mill, a long cylinder mill, a tube mill, and a conical mill.
B: to eliminate defects (Defect) not timely. The ball mill is a crushing key equipment after the material is broken. For example, loose bolts falling, individual liner fracture (fracture) off, if not timely replacement of the defective gradually (step by step) extended, will cause the cylinder liners and other adverse impacts deformation (deformation).
2 Effects plate materials
Analysis (Analyze) from the physical properties of the backing material, the main parameters affecting the effect of wear is the hardness and toughness two indicators (target aim) of matching material high hardness, its good abrasion resistance, a substantially proportional relation, since the ball running them, the ball is cascades down state, the material will have a liner and the impact energy, the impact energy depends on the size of to the ball diameter and the diameter size of the grinding barrel. (Material play a decisive role)
3. Effect of medium
is often broken media mill: all types of mine material (Mn (Manganese) ore, copper, tungsten (Wolfram) ore, chromium (the Chromium) Ore etc.), all kinds of stone (limestone, granite, gneiss, basalt, gray rocks, etc.), power industry used coal. Hardness index medium is an important basis for decision liner wear failure, the higher the hardness, lining life cycle (lifetime) shorter, on the contrary, the use of cyclical growth. Thermal power plant fuel (fuel) coal is the primary milled medium mill can grind coefficient of coal around the country generally between 0.8 to 2.0, if the incorporation of excessive coal gangue, sand, stone, not only hair heat (heat) insufficient, and grindability poor, will inevitably lead to premature failure of the liner.
4, affect the design and manufacture of installation quality
Function of a substantially two ball mill liner, a protective cylindrical body is followed in a particular rotational speed of the ball to the required lift height of the ball cascades like whereabouts, milled to achieve the desired effect. The ball mill is one of the high fine mills widely used in industrial production, and there are many types. The ball mill is suitable for polishing various ore and other materials, which are widely used in different industries such as mineralization, building materials and chemicals, can be divided into dry and wet-forming milling methods.
in the energy ball mill, ceramic (material: non-metallic mineral) ball mill, a conical ball mill, a ball mill device 30 years, has a ball millMore than ten advanced patents, leading (first) in the industry's domestic ball mill production (Produce) enterprise, quality quality, perfect after-sales, escort your equipment and production!
