Cemex Grinder Roll Supplier AGICO CEMENT introduces the precautions for purchasing vertical grinding mill Grinder Roll.
If the purchased grinding roller does not meet the specifications of the equipment, it will cause the loosening of the grinding roller and the interface.
In such a use process, it is very likely that the grinding roller will fall off or the grinding roller will break, which will cause the equipment to fail to operate normally, delay production operations, and cause unnecessary economic losses to the enterprise.
Therefore, we must remind everyone here that we must choose the appropriate size and specification of the vertical grinding roller model.
Cemex Grinder Roll and liners can be customized to AGICO CEMENT at info@cementplantparts.com.
Just provide us with the required product name, model, quantity, parameter requirement information.
According to the requirements of customers, select appropriate molds for modeling design and customization, and strictly follow a series of standard technological processes to cast high-quality high-chromium roll sleeve castings.
The company takes high wear resistance and guaranteed installation size as the product goal, and strives to create products that satisfy customers.
For laymen, it is normal for them not to understand the materials and uses of these vertical grinding rollers. However, as a source manufacturer that has been focusing on the production and customization of vertical grinding rollers for many years, we need to be familiar with the pros and cons of various lining materials. and recommend suitable products to customers.
Next, we will give a general introduction to the common vertical grinding rollers. Vertical grinding rollers can be divided into three types according to their materials: surfacing grinding rollers, ceramic grinding rollers, and high-chromium grinding rollers.
1. Surfacing grinding roller
The surfacing grinding roller is made of 42CrMo-A steel by one-time forging, and the wear-resistant layer of the stick surface is surfacing by 2+3+2 surfacing welding. Generally, the thickness of the wear-resistant layer is 15-20mm, the hardness is HRC56-60, and the process is complicated. If the time is long, it should be surfacing multiple times, the amount of welding wire is large, the downtime is long, and the maintenance cost is high.
If the surfacing welding is not in place, the grinding roller may crack and cause losses.
2. Ceramic grinding roller
The metal base is mainly used in line with ceramics, although it has certain advantages compared with surfacing grinding rollers.
Due to the honeycomb structure on the surface of the ceramic grinding roll, the surface friction force and the effective grinding area are reduced, the grinding capacity is weakened and the energy consumption is increased, and the ceramic grinding roll is often expensive.
3. High chrome grinding roller
The high-chromium grinding roller is made of high-chromium cast iron grinding material, which has the characteristics of good crack resistance, good wear resistance and strong load bearing capacity, which greatly increases the service life of the roller sleeve and reduces the operating cost.
The vertical grinding roller is designed with a tire type to avoid the edge wear effect of the working surface of the roller sleeve.
Vertical grinding rollers of different materials have different advantages. How to choose a suitable vertical grinding roller material, I believe that each industry has its own judgment.
With the increasing emphasis on quality in various industries, the grinding requirements of vertical mills are also increasing. The use of grinding rollers can improve the production efficiency of vertical mills and reduce the cost of enterprises in the grinding process. Production costs, but also can improve the economic benefits of enterprises.
