How to Prolong the Service Life of Ball Mill?
The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Clients from many countries may complain that the service life of ball mill liner plate is too short. So how to prolong the service life of ball mill liner boards become important.
1. Grinding medium
Ball mill can grind all kinds of raw materials like copper, manganese ore, chrome ore, manganese ore, all kinds of limestone, granite, green stone and coal used by electricity industry. The hardness index of medium decided the performance of ball mill liners, the higher hardness of lining board, the shorter of service life.
2. Operation
If there is defect in operating, for example, bolt looseness and drops, individual liners falls, timely repair is needed. If the broken parts are not changed in time, defects will gradually spread to other section of the machine, making larger damages to other lining board and cylinder.
3. Liner materials
According to the physical properties of the liner plate, the main parameters that affect anti-wear effect are matching rate between hardness and impact toughness, the higher the hardness of the material, the better anti-wear ability, and they may achieve a direct ratio ,making the balls fall like waterfall and impact on the liner board in operation process. The impact strength is decided by the size of the steel balls and the cylinder.
