Compound Fertilizer Production Process

Device Configuration

1. Automatic batching system: The automatic batching system is mainly composed of a feeding system, a weighing device, a silo, and a conveyor belt. And the static batching system has both the speed of dynamic batching and the accuracy of ordinary static batching (0.2%). 2. Belt Conveyor: The working principle of the mobile elevating belt conveyor is the same as that of the ordinary belt conveyor. Because of the addition of lifting and moving devices, the mobile lifting belt conveyor has increased mobility, and can be pushed or pulled by power locomotives such as forklifts to suitable locations for loading and unloading goods according to site conditions. 3. Disk mixer: This machine is a new type of disk mixer. It consists of a stirring plate, a discharge port, a stirring arm, a frame, a gear box and a transmission mechanism. It is characterized in that the output shaft end of the reducer drives the stirring main shaft. , make it run, there are fixed stirring teeth on the stirring shaft, and the stirring shaft drives the stirring teeth to fully stir and mix the materials. 4. Rotary drum granulator: This machine is a rotary drum granulator developed by our company staff with many years of experience in compound fertilizer production. The machine has beautiful appearance, simple operation, uniform drying, convenient maintenance, etc. Features, this product is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizers. 5. Dryer: This machine is a rotary drum dryer developed by our company staff with years of experience in compound fertilizer production. The machine has the characteristics of beautiful appearance, simple operation, uniform drying and convenient maintenance. 6. Drum screening machine: This series of drum screening machines is a common equipment in the production of compound fertilizers. It is mainly used for the separation of finished products and returned materials, and can also achieve product classification and even classification of finished products. The machine adopts a combined type The screen is easy to maintain and replace. It has simple structure, convenient operation and stable operation. It is an ideal equipment in the production of compound fertilizer. 7. Coating machine: The complete set of rotary coating machine is composed of screw conveyor, stirring tank, oil pump, main engine, etc., powder coating process or liquid coating process. It can effectively prevent the agglomeration of compound fertilizers. The main unit is lined with polypropylene or acid-resistant stainless steel. 8. Packaging scales: Automatic packaging scales, also known as automatic packaging machines, can be divided into semi-automatic packaging scales and fully automatic packaging scales. The packaging scale is mainly composed of automatic quantitative packaging scale (consisting of storage hopper, feeder, weighing bag hopper, kneading mechanism, computer control, pneumatic execution part, etc.) and optional parts (conveyor, sewing machine/heat sealing machine). )composition.

The compound fertilizer process can be divided into raw material composition, raw material mixing, raw material granulation, particle drying, particle cooling, particle grading, finished film, finished product packaging, etc.


1. The equipment has low investment and good economic benefits. 2. The complete set of equipment has a compact layout, is scientific and reasonable, and has advanced technology. 3. Energy saving and consumption reduction, no discharge of three wastes, stable operation, reliable operation and convenient maintenance. 4. Wide adaptability of raw materials, suitable for granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, etc. The product has a high granulation rate. 5. It can produce compound fertilizers of various concentrations and various types (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.). Especially rare earth, potash fertilizer, ammonium bicarbonate series compound fertilizer granulation.
