At present, the role of bio fertilizer granulating extruder in fertilizer treatment inevitably exists equipment pressure in the wear process of bio fertilizer granulating extruder. How to start from multiple wear causes and consider corresponding measures? The roller extruder is mainly aimed at dry powder materials. Due to the different hardness of materials, uneven force will be generated during extrusion and rounding, thus increasing the wear of roller skin. How to solve such problems?

In terms of different material factors, since the surface of the bio fertilizer granulator is friction material and direct force, when the roller surface is worn, the friction and back pressure of the material cannot be ignored. This force requires higher quality roller skin, lower quality wear rate and lower quality wear rate. If the feeding is uneven, the center of the parallel rod axis of the bio fertilizer granulator is parallel to the surface of the roll sheet. The feeding at one end and the feeding at the other end will cause uneven force at both ends of the roll, thus increasing the friction between the roll and the material, resulting in wear of the roll.

As the roll cover of the bio fertilizer granulator is made of stainless steel, it has a strong response to the pH of the material. Due to the lack of moisture and alkalinity of the material, the roll surface will be subject to acid and alkali corrosion, which will damage the roll. If the operation procedure cannot be operated, the gap between rolls will not be adjusted correctly and contains impurities such as iron and sulfur. The color will seriously damage the roll surface. Measures to reduce wear of the shell of the bio fertilizer pelleting extruder.

Due to the inevitable wear of the roll in the granulation process of the bio fertilizer granulator, if used properly, the wear of the roll skin can be effectively reduced, thus extending the service life of the roll. According to the above factors, wear can be reduced from the following aspects. The new bio organic fertilizer granulator can improve the dryness of the granules, prevent adhesion after granulation, and improve the quality of the granulating products.
