How to improve the wear resistance of the ultrafine mill?

Ultrafine mill is a common ultrafine powder processing equipment, it is suitable for raw material, gypsum, coal and other materials, fine powder and ultra-fine powder processing. The ultrafine mill pulverizer works directly with the ore when it works, so in actual production and use, the wear of the equipment is very fast, which affects the economic profit of the user. So, how to improve the wear resistance of the superfine grinding machine powder machine?

The applicable material of the superfine grinding machine is mainly about 7 moth hardness. When the equipment is running, the flour mill mainly depends on the grinding roller and the grinding ring to grind the materials. When they are repeatedly contacted with the material in the grinding process, the pressure and friction will be more frequent, and the temperature of the contact surface will also continue to rise. Therefore, in order to improve the wear resistance of the ultrafine pulverizer, the wear resistance of the grinding roller and grinding ring should be guaranteed.

The wear resistance of grinding roller and grinding ring is mainly reflected in its toughness and hardness. So, how to guarantee its toughness and hardness? On the one hand, it should be made of high wear resistance, high hardness and high toughness. Not only the grinding roller and grinding ring, other accessories superfine grinding machine powder machine, such as blade, blade frame, bearing, gland, nut etc. to ensure the material hardness and toughness. On the other hand, it is necessary to adopt advanced manufacturing technology, reasonable casting and heat treatment process is the key factor to ensure its service life. In a word, the use of qualified materials and the formulation of reasonable production technology are the necessary conditions to ensure the wear resistance of ultrafine mill.

2. The humidity of elements. When the Raymond mill’s material is as well moist for milling, the materials is effortlessly adhere to inner of Raymond mill and also simply conveying the program in the up coming block, leading to diminished means of Raymond powder mill.
3. The fineness with the output material. The finer materials you want, the little capability of Raymond mill current.
4. The composition of material. Fine milling material contained prior to milling is poor for Raymond mill. Due to the fact these fine powder have adhesion results that very easily block conveying. So we ought to procedure just before commencing of Raymond mill.
5. Materials viscosity.
6. Raymond mill key part’s wear resistance. In our typical sense, the capacity of Raymond mill is as much as the put on components.

The price of ultrafine grinding mill roller

Ultrafine mill internal grinding roller is an important component of crushed material without it, ultra fine mill to complete the production process of the material, when students sweat, the parts due to friction force will be worn, and the service life of parts is limited, that will cause the the service life of the parts gradually decreased, when can’t help production, there is damage to the phenomenon, this time need to be replaced.

The replacement of this part involves the cost. So how the price of the roller is a problem that the customers are concerned about. We are going to introduce how much money we need to buy the grinding roller of the ultrafine grinder.

A model for roller prices, because more types of mill, mill of the same type has many types, they have different capabilities and purposes, so the cost of production there will be some differences, this phenomenon is caused by the difference of equipment price, so the price is not the same equipment accessories;

Two, the quality of influence on grinding roll price, good quality, long service life of parts, so the use of ultrafine mill, the damage frequency is relatively low, the efficiency of the equipment will be relatively high, the premise of good quality is the choice of the material, and the casting process, so the production cost of equipment will be relatively high, so the price will be relatively high;

The article mainly introduces the ultrafine mill roll price, the above analysis the importance of the grinding roller, and then introduces the two aspects of the influence of the price, a price is different models are not the same, the two is the quality of different prices are not the same, so when choosing a specific price, also need to look at the equipment the quality and type and, in addition, in the actual production process, the grinding roller of possible problems, the need for timely treatment and inspection, prevent the production caused greater harm.

Generally speaking, we need to maintain and maintain the grinding roller in production, extend the service life and reduce the replacement times in the production process, which is a more effective way to reduce the cost of ultrafine mill production.
