Cement Ball mill is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores. Cement ball mill is not only suitable for over-flow grinding, but also applicable for cyclic close-flow grinding together with powder collector.
Cement ball mill is an efficient tool for fine powder grinding. The Cement ball mill is used to grind many kinds of mine and other materials, or to select the mine. Cement ball mill is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different expelling mine.
LYHMC Cement ball mill Feature:
1.The cylindrical mill adopts the driving type edge-driving, center-driving, edge-driving with multi-point meshing, etc; driven by asynchronous motor +reducer +pinion and gear as well as synchronous motor +
air l\clutch + pinion and gear.
2.Generally supported by static-dynamic pressure bearing on both ends. Fuuly closed self-aligning 120º osculation rocker bearing is used. Also single or double slipper staic- dynamic bearings can be used. The bush is made by NC machine.
3 .The large open gear is designed using AGMA standard, Equipped with reliably sealed gear housing and grease ahtomatic spraying lubrication system.
The shell is key part of a mill. Carry out finite element analysis on it with computer to ensure the reliable operation;
4 .The shell is automatically welded, ultrasonic inspected, wholly annealed and machined by large special machine tools on one chucking; there special seal on static-dynamic connection parts , ch as feed and discharge hoper, trunnion, etc, to prevent oil and slurry leakage;
5 .The liner is of wear-resistance material mad by our company, wich has been specially heat-treated, with high hardness and long service life. Also other wear-resistance casting or rubber liner can be used;
6. There are slow speed drive for medium and large mill;
7.The high and low pressure lubricating station is equipped for medium and large mill;
8.The control and protection system is controlled by PLC. technical advantages
1. High capacity and Low consumption: the capacity of SCM series super-micro mill, compared with that of jet mill and mixing mill, has been improved by 40% under the same final fineness and electric power.
2. High fineness and Flexible adjustment: the final fineness can be adjusted from 325 meshes to 2500 meshes according to the requirements, and the fineness can reach D97≤5um.
3. Trustworthy security: there is no rolling bearing and bolt in the mill chamber, therefore, the bearing and sealing elements will not wear out easily, and the bolts will not loose to make damage to the equipment.
4. Clean and environment-friendly: equipped with the pulse filter and sound absorber, the mill reaches the environment-friendly standard of our country and reduces the dust and noise greatly.
Cement Ball mill working principle
Cement Ball mill Main feature and working principle
2.1 Cement Ball mill Main feature
This mill is center driven, which adopts slipper bearing support, new type combination design baffle plates and discharge grate, to raise crushing, grinding and screening efficiency. 2.2
The material is fed into the rough grinding bin through the feeding device; then crushed under the impact and grinding of grinding agent (steel ball with longer diameter), and the finer material enter into the fine grinding bin through double layered baffle plates and other material which can not enter into the fine grinding bin will continue be crushed in the rough grinding bin; the material which enter into fine grinding bin will entail further impact and grinding of smaller grinding agent, and the finished goods which meet the degree of fineness will enter into discharging device and been discharged from the mill.
The mill mainly consists of feeding device, slipper bearing, rotating part, discharging device, lubricating device of slipper bearing. 3.1 Feeding device
