How to reduce the roll skin wear on the roller press granulator?

Fertilizer granulator machine is an important machine for the production of organic fertilizers and compound fertilizers. It plays an important role in the fertilizer production industry. The granulators used in our usual production activities are diverse, depending on the production of fertilizers and the characteristics of raw materials; we should choose the right fertilizer granulator.


The roller press granulator is produced by a dry-free normal temperature process and molded at one time. The equipment investment is small, the effect is quick, and the economic benefit is good. And energy saving, no three waste discharge, stable operation, reliable operation and convenient maintenance. The equipment has wide adaptability and is suitable for granulation of various raw materials such as compound fertilizer, medicine, chemical industry and feed, and the product has high granulation rate.

When the roller press granulator is used for granulation, the roll surface will wear gradually. The wear of the roll surface will affect the production efficiency of the roller press granulator and the finished product size. Seriously, it is necessary to stop and replace the new roll surface. It is therefore necessary to ensure that the material is fed uniformly into the granulator along the length of the roll. If the feeding is uneven, an annular groove will appear on the roll surface, which will affect the normal operation of the granulator and the product granularity will be uneven. When feeding, the feeder not only needs to feed evenly and continuously, but also has the same length as the length of the roller.

Wear on the roll surface is inevitable. If we can repair it when it is worn to a certain extent, can we avoid the need to replace the new roll surface at the end? Yes, in the use of the roll granulator, the roll surface needs to be repaired frequently.
The roller extrusion granulator repeatedly works after a period of time, the roller skin is seriously worn, can no longer be used, needs to be replaced, the roller granulator roller skin, the stainless steel mold fittings, the improved roller is replaced with special steel, and more Corrosion resistant and wear resistant. The equipment can be used in one machine. According to the user's requirements, the size of the grain is selected, the roll skin is replaced, and the roll skin of the same type is common.
