Classification of Tube Ball Mill

1. According to the cylinder length and diameter ratio classification
(1) Short ball mill length to diameter ratio below 2 for the short mill, or ball mill. Generally for the single warehouse, for rough grinding or a grinding.
(2)Medium long mill Medium long mill diameter ratio is about 3.
(3)Long mill length to diameter ratio of 4 or more for the long mill or tube mill. In the long grinding and long grinding, the internal general divided into 2-4 positions. In the long cement plant with more.
2. According to the grinding medium shape classification
(1) Ball mill The grinding medium is mainly steel or steel section. This mill is most commonly used.
(2) Rod mill The diameter of 50-100mm steel bar for grinding media. The ratio of rod length to diameter is 1.5-2.
(3) Baseball mill This type mill usually has 2-4 positions. In the first warehouse into the cylindrical steel bar as a grinding medium, after the warehouse is loaded into the steel ball or steel section. The ratio of the length of the baseball mill should be around 5, the ratio of the length of the bar to the effective diameter of the mill should be between 1.2 and 1.5, and the rod length is about 100 mm shorter than the bar to facilitate the parallel arrangement of the steel bars, Chaos.
(4) Gravel grinding mill Grinding medium for the gravel, pebbles, porcelain ball and so on. Made of granite and porcelain. For white or colored cement and ceramic production.
3. By way of discharge classification
(1) Tail unloading mill Grinding material from the end of the mill feed, discharged from the other end, known as the tail unloading mill.
(2) Unloading mill Grinding material from the mill at both ends of the feed, unloaded by the middle of the mill cylinder, known as the unloading mill. This type of mill is equivalent to two ball mill parallel use, so compact, streamlined process. According to the tail unloading mill discharge methods are lattice discharge, overflow discharge, the surrounding discharge and wind discharge and other types
4. According to the transmission method classification
(1) Center drive mill Motor through the reducer to drive the mill unloading side of the hollow shaft and drive grinding body rotation. Deceleration and the out of the shaft and the center line of the mill in a straight line.
(2) Edge drive mill Motor through the reducer drive to the discharge end of the cylinder on the large gear and drive the cylinder barrel rotation.
According to the process can be divided into dry grinding machine, wet mill, intermittent mill and continuous mill. Continuous mill and gap mill compared to the former high yield, the unit weight of the product of low power consumption, high degree of mechanization and the required fewer operators. But the infrastructure investment costs, operation and maintenance more complex. Now intermittent mill is rarely used, often used as laboratory grinding.
