New granulation process of organic fertilizer production line for organic fertilizer equipment

First of all, the technical staff will combine the market demand or customer demand, combined with the market situation of the raw materials, and formulate the corresponding fertilizer production formula.

According to the ingredients requirements of the workshop personnel:

The first step: the operator of the raw material mixing section strictly adds the quantity of each raw material according to the requirements of the technicians, and adds various raw materials, such as N, P, K and additives, in the electronic belt scale or batching machine as needed Configuration. The process of adding raw materials requires that the raw materials be powder or granules, and the raw materials must be uniform and sometimes uninterrupted. Otherwise it will affect the measurement accuracy and the control of the granulation process, and ultimately affect the product content. The metered material flows into the raw material crusher and enters the second part.

Broken part:

The metered raw materials flow into the feed port of the pulverizer, and the motor of the pulverizer drives the rotor body to run at a high speed to pulverize the raw materials, so as to achieve the required fineness for granulation. In addition to pulverization, the pulverizer also has the function of secondary mixing. The crushed material enters the belt conveyor through the discharge port, is conveyed by the belt conveyor to the pelletizer, and then enters the third part.

Granulation part:

The crushed raw materials enter the raw material belt conveyor and then sent to the granulator for granulation. The solid fertilizer powder to be granulated rises through the rotation of the cylinder and rolls down under the action of gravity. At the same time, a certain proportion of binder is added according to the amount of granulated raw materials. The material is wrapped layer by layer on the surface of the pelleting core, thickened layer by layer, and granulated gradually. Under the action of the above-mentioned force, the material gradually forms the bottom core until it reaches the granulation requirements and enters the drying zone.

Dry part:

The dryer adopts the methods of cylindrical edge transfer, flange connection and direct heat transfer, and is suitable for drying compound fertilizer after granulation. The material to be dried enters the drying area of ​​the board copy in a special combination. Due to the tilting and rotating movement of the body and the wooden board, the material is continuously absorbed by the wooden board, fully dispersed and moved longitudinally. The high-temperature furnace gas performs sufficient heat exchange to evaporate water and dry the material. Need to dry materials and flue gas, please use the downstream flow, slightly negative pressure operation. There is a secondary granulation area in the dryer, which can be used for secondary granulation of some ungranulated materials, which is beneficial to improve the granulation rate of the system. During the drying process, it is necessary to monitor at any time, and adjust the temperature of the furnace head and furnace end of the dryer by adjusting the temperature of the hot air furnace and the exhaust fan according to the process requirements, so that the dried material can reach the best drying index. The material that has completed the drying operation is conveyed to the fifth part through a belt conveyor.

Cooling part:

The rotary cooler is mainly used to cool the dried compound fertilizer products. It can directly cool hot granular fertilizers to near normal temperature. The material entering the cooler continuously moves forward under the action of the rotation and tilt of the machine body. At the same time, the induced draft fan encounters the material in countercurrent from the tail to the head of the cooler and takes away the heat material. During the cooling process, the cold wind will also take away some water. The cooled material is easy to pack quickly to prevent agglomeration during storage. The machine adopts micro-negative pressure operation, which reduces pollution and improves the working environment. It has the characteristics of reasonable structure, stable operation and strong adaptability. The cooled material is conveyed to the sixth part through a belt conveyor. Organic fertilizer equipment. Organic fertilizer production line. Organic fertilizer granulator. Organic fertilizer extrusion granulator.

Large particle crushing and screening part:

Mainly used to separate fine powder, finished product and large particles in materials. First, the fine powder in the semi-finished product is separated, and then the large particles are separated. The separated large particles are crushed by the crusher, and enter the return belt together with the separated fine powder, and then return to the granulator for granulation. The finished product enters the seventh part.

Packaging part:

The finished product is lifted to the material box on the packaging machine through the belt conveyor, and discharged into the scale body according to the set weight for automatic weighing operation. The weighed material enters the sewing area through the conveyor belt to input the sewing operation into the finished product warehouse.
