Analysis of cause effect analysis of ball mill liner grinding

　　1, the impact of working conditions A: The outcome is abnormal, the adjustment is improper, the empty warehouse is operated, and some steel balls are directly frozen and hit the barrel liner, forming two body wear, which is the case of the liner and The broth of the steel ball, the wear chance increased significantly, is a very harsh (liè) operation method.

　　The ball mill is different from the mineral 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: Eliminating defects are not in time. The ball mill is a crushing key device after the material is broken. For example, the bolt is loose drop, and the individual liner fracture falls off, and if there is no timely replacement, it is expanded to the deficiencies, and other lining and causing the cylindrical deformation.

　　2, the effect of liner material is analyzed from the physical properties of the liner material, which affects the main parameters of the anti-wear effect. The matching problem of the hardness and impact toughness, the hardness of the material is high, and its resistance Working performance is good, basically a proportional relationship, because the ball mill is running in operation, the steel ball is falling in the waterfall, and the material and lining will generate an impact work, and the size of the impact depends on the steel ball diameter and grinding. The size of the cylinder diameter.

　　3, the medium affects the common crushing medium (substance determined): all kinds of mine materials (Manganese) mine, copper mine, tungsten (Wolfram), chromium ore, etc.), all kinds of stone (Limestone, granite, flax rock, basalt, gray green rock, etc.), coal used in the power industry. The hardness index of the medium is an important basis for determining the loss of the ground, the higher the hardness, the shorter the use cycle of the liner, which is reversed, and the cycle growth is used. Fuel, Fuel, Fuel, is the main rosary medium of the ball mill. The grinding coal coal from all over the country is generally between 0.8 and 2.0. If there is excessive coal gangue, sand, stone, not only Insufficient heat (heat), and abrasion resistance, it will inevitably cause the liner to fail.

　　4, the effect of designing manufacturing and installation quality is roughly two, one is a protective cylinder, followed by promoting steel ball to the required height at a particular speed, so that the steel ball is waterThe cloth is placed, achieving the ideal rosary 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 dust grinding various ore and other materials, which are widely used in different industries such as moisture, building materials and chemicals, can be divided into dry and wet two kinds of grinding methods.

　　Engaged in energy-saving ball mills, ceramics (raw materials: non-metallic minerals) ball mills, cone ball mills and other ball mill equipment, with more than ten ball mills, leading (leading) in the industry's domestic ball mill production (Produce) enterprise, quality quality, and perfect After the sale, escort your equipment and production!
