Talk about ball mill rubber liner related knowledge
The ball mill rubber lining is used to maintain the cylinder body, so that the cylinder body is free from direct impact and friction of the ball mill steel ball and material. The lining plate of different ways can also be used to adjust the movement condition of the grinding body to enhance the grinding body to the material. The destructive effect helps to improve the grinding power of the mill, add value, and reduce metal consumption. The domestic high-manganese steel of the ball mill is gradually replaced by the medium-alloy steel lining. However, with the continuous use of the medium-alloy steel lining in the ball mill lining, the manganese steel and other linings have gradually replaced the main stream.
The barrel ball mill liner has an influence on the movement rules of the grinding body in addition to the maintenance cylinder. The material of the shape of the liner is different for the request of different working conditions (destruction or fine grinding). When the damage is dominant, the lining of the lining is required to be strong, and the lining should have an outstanding impact resistance. When the fine grinding is dominant, the lining of the lining is relatively small, and the lining of the lining is relatively small. The effect of the recommendation is weak, the impact is small, and the grinding effect is strong. The liner is requested to have outstanding wear resistance. Features:
1. High wear resistance and impact resistance
The alloy steel lining in the double medium quenching has a scientific and reasonable alloying element formula, so that the lining plate has outstanding physical and chemical functions, the hardness is above HRC45-55, the impact resistance value is above 25J, and the service life is more than twice that of high manganese steel. Can accept endless impact strength. In the operation, the shape of the lining can be maintained for a long time to ensure the mill's stability is improved by more than 5%.
2. High strength and high resistance In the quenching process of the lining, the special double-medium quenching agent with good thermal stability function is selected as the medium to make the product reach the cooperation of high strength, high hardness and high tolerance, so as to satisfy the skill request for wear resistance.
3. High cost performance, strong habits
It has the characteristics of high quenching hardness and high resistance value, which makes the lining board have outstanding wear-resisting function. Compared with high-manganese steel lining, alloy steel ball mill lining in medium alloy double-medium quenching The board reflects an excellent price/performance ratio. Can be used to mining wet grinding, dry grinding, mixed grinding and so on.
In terms of the wear properties of the ball mill rubber liner, there are many similarities between the wear of the ball mill rubber liner and the manganese steel liner, but there are fundamental differences. The primary difference between ball mill rubber liner and manganese steel liner is that in addition to the common elasticity of rubber, it can be used to make wet mill liner, which is not affected by the corrosion and wear effect of pulp, and different rubber types and functions can be obtained. A ball mill rubber liner with different wear resistance, elasticity, impact resistance and chemical resistance to receive the impact and grinding effect of the medium and mineral material during the grinding process.
Therefore, the use of rubber to manufacture wet mill liners, it is necessary to make full use of this advantageous property of rubber elasticity, to achieve the cushioning effect of the liner and reduce wear, select a common wet formula planning, contact nano-composite dispersion skills, and obtain excellent functions. Wet nano-rubber has excellent wear resistance, strength and elasticity, and its service life is greatly increased.
The ball mill rubber liner is used to find Longbang rubber. For more than ten years, it has focused on the production of rubber products and conveyor belts. It is a big manufacturer that customers trust.
