Dry Powder Double Roller NPK Fertilizer Production Line SGS

Chemical Dry Powder Double Roller Extrusion Granulator Npk Fertilizer Production Line

Product description

NPK Fertilizer Production Line can produce all kinds of concentration, multiple types of compound fertilizer (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetized fertilizer, etc.) . In particular, it can produce rare-earth, potash and ammonium bicarbonate series of compound fertilizer granulating. It fills the domestic blank and ranks the leading level in China.

Working principle

Working flow: input ( If blocked, use chain crusher to deal with ) ---- granulation - screening (select the right sieving hole diameter)----finished granules---- the next process (optional equipment: 1, screening machine: the size of the granules will be more accurate. 2, coating machine: make the appearance of the granules more good. 3, weighing and package: facilitate the sale and transportation of products.

This series of roller granulation belongs to extrusion sliding model, whose working principle is: the belt and belt pulley are driven by an electric motor, and transmitted to the drive shaft by reducer, and work in the same direction through the open gear and the passive shaft.The material is added from the feed hopper, extruded by the roller, demoded and pelleted, and passed through a pair of chains to the crushing screen studio, where the finished product pellets (balls) are screened and separated, and then the material is returned and mixed with new materials for granulation.With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.

Advantages

1.less investment, good economic returns.

2.A complete set of fertilizer extrusion granulator is compact, scientific, reasonable and advanced technologies.

3.No waste discharge,stable,and easy operation and maintenance.

4.this roller extrusion granulator can directly squeeze dry powder materials into granules,which belongs to dry method granulation.

Working Processes

1). Mixing Process:
Mix the needed Chemicals together, such as NPK, NP, ANP, DAP, MAP, CAN, SSP or Chemical ASO4 MOP SOP MAP CaCo3

2). Crushing Process:
Lump materials should be crushed after the fermentation process. It is difficult to make the matter into granules manually. In this way, it is necessary to use fertilizer crusher. We recommend customers choose high moisture materials crusher machine, as it can crush semi-wet material and with high crushing efficiency.
3). Granulating Process:
It is the important production process in the whole production line. According to different requirements, nutrients can be added. Spherical particals are processed, saving plenty of energy. Therefore, choosing the proper organic fertilizer machine is particularly essential. New type organic fertilizer granulator is the most suitable machine.
4). Drying Process:
After granulating, the granules are in need of drying. The moisture of organic fertilizer is reduced to 10%-40%. Rotary drum dring machine is an equipment to reduce the moisture of the particles, which is feasible for organic fertilizer production.
5). Cooling Process:
In order to ensure quality, the particles should be cooling after drying with the help of rotary drum cooling machine.
6). Screening Process:
There are unqualified organic fertilizers during production. It needs rotary drum fertilizer screening machine to separate the rejected goods from standard substance.
7). Packing Process:
Fertilizer packaging machine is used for packing processed fertilizers. We can use packing machine to pack and bag the particles.It can achieve pack products automatically and efficiently.
