The double roller press granulator is the key equipment for compound fertilizer granulation. It has advanced technology, reasonable design, compact structure, low energy consumption, and is matched with corresponding equipment to form a small production line, which can form a certain continuous production and mechanized production. , No drying, room temperature production, capacity, product quality meet the technical requirements of compound fertilizer, it is the latest product of energy saving and consumption reduction of npk production line of high, medium and low concentration special compound fertilizer and compound fertilizer industry.
The double roller granulator has the characteristics of low energy consumption, high energy saving, low investment, simple operation, and pollution-free equipment emissions. The distance between the pressure rollers should not be too small or too large, and should be adjusted within the specified range. Secondly, the pressure cover on the bearing seat side should be avoided to be too loose or too tight, which will cause the shaft rollers to shift.

1. Uniform feeding: Since the surface of the biological fertilizer granulator is friction material and direct force, in the npk manufacturing process, when the roller surface is worn, the friction and back pressure of the material cannot be ignored. This force requires higher quality roll skins, lower mass wear rates, and lower mass wear rates. If the feeding is not uniform, the center of the parallel bar axis of the biofertilizer granulator is parallel to the surface of the roller sheet, the feeding at one end and the feeding at the other end will cause uneven force at both ends of the roller, thereby increasing the friction between the roller and the material , resulting in roller wear.
2. Material pH: Since the roller cover of the biological 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, it will cause acid and alkali corrosion on the surface of the roll and damage the roll. If the operating procedure does not work, the gap between the rollers will not be properly adjusted and contain impurities such as iron and sulfur. The color phase can seriously damage the roll surface.
