Introduction of Pulverized Coal Ash Grinding Ball Mill
Brief introduction of Pulverized Coal Ash Ball Mill :
Ball mill is mainly used to grind materials in mineral, cement, refractory, chemical industry, etc. Ball mill has dry and wet types. When wet ball mill works, certain water and other liquid will be added into materials to increase the 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, thus improving the capacity.
Features of Pulverized Coal Ash Ball Mill :
1. Large application range, simple structure and convenient maintenance;
2. Large capacity and continuous operation;
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
Working principle of Pulverized Coal Ash Ball Mill :
The grate ball mill is a horizontal cylinder rotating device driven by gears with two silos. The materials get into the first silo through the feeding quill shaft from the feeding device spirally and evenly. There are ladder lining board and corrugated lining board in the first silo loaded with steel balls of different sizes. The centrifugal force produced by the rotation of the cylinder raises the steel balls to a certain height which then fall down, thus making thumping and abrading to the materials. After the coarse grinding in the first silo, the materials get into the second silo through the monolayer partition panel with flat lining board embedded with steel sections for further crushing. The powder of the materials will be discharged from the unloading board to finish the grinding work.
Structural features of Pulverized Coal Ash Ball Mill :
The structure of our high-efficient and energy-saving ball mill is different from the traditional ball mill. The body and the bottom frame of the machine is integral, so that it can be craned and put on the base in one step. The principal axis adopts double-row centripetal spherical roller bearing. Its energy consumption is reduced by 30%, and the materials discharging mode is force by grate instead of control discharge by overflow, so that the fineness of milled materials is promoted, and the processing volume is increased by 15-30%.
