What problems should be paid attention to in fertilizer granulation by roller granulator?

The roll extrusion granulator is produced by the non-drying normal temperature process, and is formed once, and the raw material of the roll extrusion granulator is widely adaptable, and the investment is less effective, which greatly accelerates the interests of the manufacturer. The roll granulator is a molding equipment that can make powder or small granular materials into a specific shape. It has stable operation, low noise, less dust, reliable performance and convenient maintenance.

Characteristics of Roller-to-Roller Extrusion Granulator

1. Roller-to-roll extrusion granulator without drying process, normal temperature granulation, one-time forming

2. Compound fertilizer roll-to-roll extrusion granulator has small power, reliable operation, no three wastes discharge, reasonable process layout and low production cost

3. The material of roll extruder granulator has wide applicability. It can be used for granulation of compound fertilizer, medicine, chemical industry, feed, coal, metallurgy and other raw materials. It can also produce various kinds of compound fertilizer with different concentration and types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.)

Precautions for the roll extrusion granulator

1. The roller extrusion granulator should be started under no load, and it is forbidden to open the material.

2. It is strictly forbidden to enter into the material to avoid breaking the roller of the granulator.

3. For the roller extrusion granulator, the gear should be smeared with yellow dry oil before starting.

4. The gear oil must be added once before the gearbox is used, and it can be used for production and replacement of gear oil every three months.

The wear factor of the roller skin of the extrusion granulator

1, material friction, back extrusion force are on the roller extrusion granulator roller wear factor can not be ignored

2. Feeding uniformity factor.On the roller extrusion granulator double stick axis and roller leather surface are parallel, if the material supply is seriously uneven, resulting in the roller extrusion granulator one end of material more, one end is very few, resulting in uneven pressure on both ends of the roller skin, thereby increasing the friction between the roller skin and the material, resulting in the roller extrusion granulator roller skin wear
