Product Description

Stone Ball Mill Machine for Limestone, Dolomite
HENAN ZHENGZHOU MINING MACHINERY CO., LTD was founded in 1956, after more than half a century of development, has now become a domestic first-class modern machinery manufacturing enterprises. Product marketing at home and abroad.

Energy-Saving Ball Mill are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills. Ball mill is an efficient tool for grinding many materials into fine powder. The ball mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.



New ball mill Features:
1. With high percentage of sand: A material through the machine, the sand content of up to 75%.
2. Ball mill components and supporting equipment production line can produce a variety of closed-circuit size of the product.
3. High efficiency: The ball mill used for making coarse and fine sand is more efficient
4. High utilization rate of wear parts: The machine is uniform from top to bottom in the roller wear, unlike roller mill in central depression have to be replaced.
5. The failure rate is low: The special machine ball mill's structure and sealing roller make it run more stable and more durable.

Mill Working Principal:
This machine is a horizontal type cylinder rotary device and outside the cylinder there is drive gear which drives the cylinder to rotate during the working process. Materials spirally and evenly go into the first cabin of the grinding machine through the feeding hollow shaft from the feeding device, and inside the first cabin, there are ladder lining boards or ripple lining board in which there are many steel balls with different specifications. The cylinder rotates and produces eccentric force to bring the steel balls to a certain height, and then the steel balls will fall down to impact and grind the materials. After being coarsely ground in the first cabin, the materials will go through the singlelayer partition board and into the secondary cabin in which there are flat lining board, and in the lining board there are steel balls to further grind the materials. Finally the powdery materials will be discharged from the discharging grating bar to complete the powder grinding process.
