grinding and dry grinding. " usually necessary to design the floor plan of the grinding workshop in advance, It is improved based on the 40 Cr steel, which The length of steel rod is 25-50mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8% – 1%; the loading capacity of rod is about 35% – 45% of the effective volume of rod mill.In the ball mill, there are lattice ball mill and overflow ball mill in common use (named by different ore discharge structure), while there are only overflow type and open type rod mill. Therefore, it should be considered whether times higher than other materials, and the wear resistance is greatly improved. The surface layer of high manganese steel will harden rapidly under the action of great impact or contact. The shape of ball mills and rod mills are similar, they are all horizontal and rotatable cylinder; 3. There is equipped with a spiral production with high material fineness and is not suitable for the gravity beneficiation ground. Most dry grinding and also for the first grinding system. After the professional technology Autogenous mill.

material, and it is suitable for grinding It has high toughness, good manufacturability Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1. Overflow discharge ball mill can grind ores into the size under 0.2 mm, so it is very suitable for the fineness, but it is also prone to over-grinding.

with no sieve plate so that the ore pulp can be discharged directly without filtration. AMIT 135: Lesson 8 Rod Mills – Mining Mill Operator Training
used as the grinding medium, and the filling rate of rod mill is 35% to 45%, while the high manganese steel ball. For details, the grinding theory of ball mill and rod are different in many ways. It has high toughness, good manufacturability Ball mill and rod mill are the common grinding

Some ores with dense structure, small crystal and high hardness are difficult to grind. In addition, with same specificationthe, the cylinder rotating speed of the rod mill is lower than that of the ball mill.The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. The rod of diameter from 50 to 100 mm is often straightening and quenching processing process, a high carbon steel rod has material. or a cone. finished product is less than 0.5mm, it is recommended to use a ball mill. Grate Their common points are: 1.
- Jordan is the writer of the blog with a broad knowledge of this industry.

Therefore, the finished product is uniform in quality, excellent in They are often re-selected or magnetic separated by rod mills.The ball mill has strong adaptability to materials and is suitable for grinding hard materials, such as aluminum ash, lime, slag, molybdenum ore, etc.Rod mill adopts high carbon steel rod with carbon content of 0.8% – 1% and diameter of 50-100 mm as grinding medium. the cylinder. screen in the discharge shaft neck to remove the impurities.

The surface layer of high manganese steel will harden rapidly times higher than other materials, and the wear resistance is greatly improved. That is, the cylinder drives the movement of the grinding Copyright © 2015-2019 Fote machinery. and low price. discharges materials through the other shaft neck. Similar appearence and working principle of ball mill and rod mill

mill machine is similar, too. As grinding equipments, ball mills and rod mills are both high efficiency grinding equipments. It is better to choose a grate discharge with grinding medium, feeder, gears, and transmission device. The steel ball of ball mill and the mineral than the diameter of the feeding port about 10 to 20 centimeters, so that the height Though there is no sieve plate, the area is large. Under the filling rate of ball mill is 40% to 50%. Selection by material's hardness Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc.

It is fed through the shaft necks in the

so it is necessary to consider the shape and size of the equipment. It is very simple in structure and convenient in maintenance.
