Specially designed for formula fertilizer, the equipment is a patented product of Beidou. It adopts static measuring for mass batching, which ensures a higher capacity and higher efficiency. The bidirectional quadruple-screw blender is used, and its blending silo operates to prevent fertilizer separation, which greatly ensures a good mixing uniformity. Thanks to the intelligent weighing control, the parameters can be conveniently adjusted and set; the compensating feed and zero setting can be automatically controlled; the flow rates for coarse fertilizers and fine fertilizers are adjustable. The high-performance sensor, highly adaptive, is able to process CPU data at a high speed. The main frame of the equipment is made of industrial-grade stainless steel, making it adaptive to extreme environment. The equipment is compactly designed, which facilitates a fast batching and blending. For that reason, fertilizers will not go damp easily due to a short-time exposure to air, thus greatly reducing the influence of humid air on BB fertilizer production. Besides, the equipment has also solved the problem of fertilizer mixture separation which frequently occurs to common equipment due to the difference in fertilizer proportion and granularity, thus improving the batching precision. All the control instruments and actuators of the system are imported products and featured with high precision, fast speed and long service life, which eliminates the influence of fertilizer properties, mechanical vibration, air-pressure and voltage fluctuation, cold weather, etc. on the system.

The packing system consists of rationed packing scale and sack closer which operate cooperatively.

The packing system is classified into granular packing scale and powder packing scale according to the forms of fertilizers.
