Ball Mill/Grinding Mill/Rod Mill/Powder Machinery supply in China

      Ball mill/dry ball mill/wet ball mill/cement ball mill  Ball Mill is mainly used to grind materials in mineral, cement, refractory, chemical industry, etc. Ball Mill has dry and wet ways. When wet Ball Mill works, certain water and other liquid will be added into materials to increase flowability of materials, so the capacity is increased. When dry Ball Mill works, capacity is affected because material flowability is reduced, so absorbing wind device is needed on the outlet of Ball Mill, and then negative pressure is formed in the Ball Mill to increase flowability of material, so the capacity is increased.
Working principle:
When the ball mill works, motor and speed reducer transmit torque force to big and small gears of ball mill, so the barrel rotates.When the barrel rotates, Steel balls or other grinding media in the barrel are lifted to a certain height and fall down freely, so materials in the barrel are impacted. Grinding media mixing with materials impact and grind materials continuously. The grinding media and materials impact and grind each other when the ball mill rotates continuously. The final product will be discharged from outlet when it meets the request, so the grinding process is finished application range, simple structure and convenient maintenance.
Featurers:
1.Large application range, simple structure and convenient maintenance;
2.Large capacity and continuous work are very obvious;
3.Barrel lining and grinding media can apply various abrasive materials;
4.Installation and adjustment are very convenient and easy to be operated. Related: dry grid ball mill  wet ball mill Our engineers will suggest the most suitable one for you according to your information.  Wet ball mill is used widely in the ore beneficiation industry,as well as the building material industry such as glass.
During the producing phase, the material and water are mixed together to grind in the ball mill. Under the effect of the flowing water,the material will get a better flow ability so the processing capacity will be higher.
We usually control the granularity of the final product with spiral classifier, hydraulic cyclone or high frequency screen etc. The product is slurry which can make fully preparation for the following concentrating and other procedure. Wet ball mill as the most important machine of ore beneficiation field, the performance of ball mill determines the whole producing plant quality. The common wet ball mill are grate type and overflow type. We should choose the suitable type according to the specific condition.     Working Principle: Wet ball mill motor driven through reduction gears rotating cylinder , the cylinder body of the broken ore and ball in the cylinder when the rotation by the friction force and the centrifugal force is brought to a certain height liner due to gravity, they have spilled into the falling and falling , impact and grinding the ore in the role gradually crushed. The ore is crushed by discharging part of the discharge tube. Discharge of minerals by spiral classifier in the classification of qualified products, grit feeder to go back through the joint wet grinding ball mill to continue . Feeder evenly continuous feed , ore feeder through the joint into the wet ball mill continuous and uniform , steady flow of material to be ground from the ball mill discharge. Dry type ball mill is named relative to wet type ball mill.Dry type ball mill mainly used in construction,chemical industry for powder making.It is an important machine in industrial grinding plant. Dry type ball mills are mainly grid ball mills.According to different materials size, you can choose the ball mill of proper length and diameter ratio,the end product can be controlled by separator.In the internal of dry type ball mill,there is ventilating device to increase the mobility of input materials.Zoneding Machine dry type ball mills have widely used in limestone,Granite, fly ash, gypsum, phosphate rock, activated carbon and cement processing.Dry type ball mill works more stable, maintain easier, it has the absolute technology and economic advantages compared with raymond mill. Dry type ball mill has following features:
1.The product size can be adjusted;
2.The system run stable;
3.There is no wearing parts;
4.Widely used in powder making.
Cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills.Cement mill is normally driven by electric motors.The output achieved by a cement mill system varies with the mill power, the fineness of the product and the hardness of the clinker.
In the technics of Cement production process, People usually choose limestones and clays as the main raw materials, crushing, concocting, grinding them into cement raw meal, feeding them into cement kiln,Cement clinker is usually ground using a ball mill.After being calcined maturity, adding appropriate amount of gypsum (sometimes mixing the mixed material or admixture) then being grinded, and the cements form.
1 Crushing and pre-homogenization
2 The prepare and homogenization of cement raw meals
3  Pre-decomposition and the burning of cement clinker
4  Cement grinding
The cement manufacturing process consists of many simultaneous and continuous operations using some of the largest moving machinery in manufacturing. 
Rubber Liner Ball Mill Rubber liner plate ball mill is a kind of energy-saving, durable liner plate ball mill combined with the advanced technology of domestic and international market, which is manufactured by our company. Adopt the wear-resistant rubber as shell inner liner plate, greatly improving the service life, significantly reduces the whole machine weight and decreased noise obviously.
Since the liner plate’s life is longer, the replacement cycle of the liner plate is extended greatly, which ensured the important requirements for equipments’ continuity and reliability during the mining production processes.
The rubber liner plate is composed of shell liner plate, lifter stripe, grate liner plate and mixed liner plate. The shell liner plate is fixed on the shell by fastening bolt. The lifter stripe is used to lift the material. This kind of phrase design structure only needs to change the lifter stripe during the production process and greatly saves the operational cost and replacement cycle of the accessories.
The rubber liner plate ball mill manufactured by our company has been successfully used in the mining area for iron, copper, gold and so on. The successfully assembled kinds of ball mill have complete specification and widely using range, the level of its device     Technical parameters:
