High efficiency mineral stone grinding Ball Mill machine /powder making mill with excellent output fineness
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.
Features:
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.
1. Ball mill equipment Introduction:
There are two ways of grinding: the dry way and the wet way. So it can be called wet ball mill or dry ball mill.
Ball milling machine grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.
2. Ball mill equipment Application:
Ball mill is 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.
3. Ball mill equipment working principle:
This machine is a skeleton pattern ball mill with horizontal cylindrical turning gear, drive by outer gear and two hoppers. The material goes to the first hopper after the spiraling by the quill shaft from the feeding equipment. The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by barrel turning to ram hard and grind material. After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scale board with steel ball inside to grind material. The powder material will be discharged from the grid plate to finish the grinding.
4. Ball Mill equipment Features:
1) Ball mill is an efficient tool for grinding many materials into fine powder.
2) The ball mill is used to grind many kinds of mine and other materials, or to select the mine
3) Ball mill is widely used in building material, and chemical industry.
4) There are two ways of grinding: the dry way and the wet way.
5) Ball mill can be divided into tabular type and flowing type according to differentexpelling mine
6) To use the ball mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.
7) As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours.
8) The longer the ball mill runs, the finer the powder will be.
9) Ultimate particle size depends entirely on how hard the material you’re grinding is, and the time how long the ball mill runs.
10) Our ball mills have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals
