The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise.Most of the energy useless lost during ball mill operation, leading to low it efficiency.But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.This does not exclude a search energy saving solutions for milling, and this handled by experts from around the world.

Ball mill 1012 is located in line 3 of the mines production circuit and had the potential and capacity to process more material if some modifications were made.Collahuasi decided to award the project of repowering this mill to metso, given the previous positive experience and years the two companies had worked together.
What industries can it be applied? ball mill is widely used in powder-making production line including cement industry, chemical industry, new building materials, fire-resistant materials, fertilizer, porcelain and glass industry for grinding iron ore, gold ore, concrete, slag, zinc, copper ore, tantalize, etc.This equipment carries on the dry type or the wet powder to each kind of ore and other gradable material rubs.
ball mill liner the liner of cement dry-type ball mill can be divided into ceramic, granite, rubber, high manganese, magnetic liner and other materials.The function of liner is mainly to protect the cylinder from the direct impact of materials and steel balls and extend the service life.At the same time, the liner plate can also adjust the running track of materials.Generally, the head grinding bin is equipped with hard liner plate, which can enhance the impact force of materials and accelerate grinding.The liner plate of the fine grinding bin is corrugated liner plate or flat liner plate, which can enhance the grinding effect of materials.
Ball mill power is relatively large, the appropriate choice of hydrostatic sliding bearing.The main bearing bush is lined with babbitt alloy bush, each bush has two high-pressure oil chambers, high-pressure oil has been supplied to the oil chamber before and during the operation of the mill, the high-pressure oil enters the oil chamber through the shunting motor, and the static pressure oil film is compensated automatically to ensure the same oil film thickness to provide a continuous static pressure oil film for mill operation, to ensure that the journal and the bearing bush are completely out of contact, thus greatly reducing the mill start-up load, and can reduce the impact on the mill transmission part, but also can avoid the abrasion of the bearing bush, the service life of the bearing bush is prolonged.The pressure indication of the high pressure oil circuit can be used to reflect the load of the mill indirectly.When the mill stops running, the high pressure oil will float the journal, and the journal will stop gradually in the bush, so that the bush will not be abraded.Each main bearing is equipped with two temperature probe, dynamic monitoring of the bearing bush temperature, when the temperature is greater than the specified temperature value, it can automatically alarm and stop grinding.In order to compensate for the change of the mill length due to temperature, there is a gap between the hollow journal at the feeding end and the bearing bush width, which allows the journal to move axially on the bearing bush.The two ends of the main bearing are sealed in an annular way and filled with grease through the lubricating oil pipe to prevent the leakage of the lubricating oil and the entry of dust.
