Causes Analysis of Copper Ball Mill Liner Wear

Copper ball mill is the key equipment for grinding again after the crushing of copper ore, which can be used with dry or wet grinding for all kinds of ores and other materials such as copper, zinc, lead, zinc, etc. Copper ball mill is one of the hot spots in the development of mineral processing technology system at present.
Parts used in metallurgy, mine, electric power, cement, petrochemical industry often lose efficacy due to wear and the consumption of wear-resistant parts is very large. Wear is universal and inevitable, which is one of the main causes of failure of mechanical parts, and the wear of lining plate is an important problem in the process of the use of ball mill.
There is much liquid during grinding material. Abrasion, cavitation, abrasion and other phenomena appear in the use of liner which life is very short. And the large diameter grinding ball (maximum diameter 160mm) has a great impact on the liner, which often causes liner broken. Conditions of wet ball mill liners for metallurgical mines (iron ore, gold ore, etc.) are bad. Under wet condition, especially in the corrosive medium, the wear rate of the same material is several times than that in dry condition.
Wet corrosion wear is not a superposition of wear and pure corrosion, but a complex process of Interactive acceleration role again and again. The service life and the failure condition are also different under the different working place and condition of the ball mill lining plate. Many liners used better in dry grinding machine often quickly wear under the condition of wet milling. The problem of the short life of wet grinding liner is not solved.
Effect traditional copper ball mill liner material is not ideal and the life is short. Therefore, in order to adapt to the harsh conditions of metallurgical mines, we must develop a new material with good performance and moderate cost to replace the traditional materials. According to the analysis of the actual working conditions of the wet grinding liner, the material of the lining plate should have high hardness, toughness and corrosion resistance. It is difficult that a kind of material is with high toughness and high strength in the actual production. and the dual metal composite materials just meet these requirements.
Dual metal composite material can be used for the copper ball mill surface, and it has good wear resistance, the overall requirements of high toughness. A single material can not meet the important parts.
