The raw material of granulation equipment of NPK fertilizer production line is made of high-strength wear-resistant alloy stainless steel (the technology is confidential, and the specific material is not disclosed to the public). The precision CNC drilling machine is used for positioning and drilling, and multiple hard surface treatment and ball and socket polishing treatment are carried out to ensure that each ball and socket on the pressure roller can be durable, corrosion-resistant, easy to demould, lasting and stable to produce full particles and smooth surface granules.
Prominent advantages of pelleting equipment in extrusion NPK fertilizer production line
1. Fertilizer granulator machine has high strength wear-resistant alloy stainless steel, congenital superior to ordinary steel.
2. Precision CNC drilling, no deviation of three axis positioning.
The introduction of foreign advanced drilling equipment, three-axis positioning drilling, to ensure that the data such as hole distance and depth are accurate and moving.
3. Multi frequency quenching treatment and shaping of hard surface ball and socket. By analyzing the element composition ratio of raw materials, a number of heat treatment schemes are formulated to achieve high strength and wear resistance of the roller.
4. The ball and socket shall be polished to ensure no residue in granulation and demoulding.
This is the second process of fertilizer granulation, which uses special grinding powder to grind the roller flexibly. Ensure that the ball and socket are smooth and clean to achieve perfect demoulding.
