Produktionslinie für organische Düngemittelpellets

The raw materials are added to the mixing pre-fermentation device, biological strains are added, the fermentation temperature is controlled, organic materials are inoculated, fully mixed and fermented. (The fermentation process of different raw materials is different, and the processing technology of corresponding organic fertilizer particles is also different)

Crush the ingredients (straw, straw, bean cake, bone meal, hoof powder, etc.), and crush the inorganic fertilizer at the same time.

The formulas of organic and inorganic raw materials are mixed according to different series of products. Mix thoroughly in a blender.If adding straw powder or organic materials with high C / N ratio and low water content, attention should be paid to the control of water content in this section. In addition, the added substances must be fully crushed.

After fermentation and storage for a period of time(according to the customer's actual process), it is crushed, and the fermented organic material is dried, crushed and sieved.But there is no 2nd crushing process when the compost material is fine enough.

In the production of special fertilizer series, according to different soil conditions and different crops, inorganic nutrients and concentrated organic matter and trace element minerals are added to make the fertilizer contain various nutrients.According to the formula, the nitrogen, phosphorus, potassium and fermented materials are computer-batched and mixed, and then sent to the organic fertilizer pellet milling machine. The formulas of organic and inorganic raw materials are mixed according to different series of products.

The raw material enters the organic fertilizer pellet mill , add appropriate amount of water or steam, and bond into pellets. Richi's granulation process has low requirements for crushing raw materials, high molding rate (over 98%), low moisture content of finished pellets, and low drying load, which can reduce the loss of effective bacteria, small dust, and good operating environment.

In the production process of bio-fertilizer, not only the water content of the pellets after forming generally exceeds the target, which requires low temperature drying, but also the moisture content of the organic raw materials after fermentation is about 30% to 40%, and the moisture of the pellets after granulation is generally 15 between 20% and 20%, the fertilizer quality index requires that the moisture content is less than 14%, and drying treatment is required.

The dried organic fertilizer pellets are sent to the cooling machine for cooling through the conveyor. The cooling process mainly uses the fan to send natural air into the cooling machine through the pipeline to cool the material. The exhaust gas from the chamber is treated and discharged into the atmosphere in the same way as the exhaust gas from drying.

The cooled organic fertilizer pellets enter the screening section, large pellets are crushed and the sifted powder return to the granulator for re-granulation, and the finished pellet product enters the automatic packaging system for packaging.

In order to facilitate storage and transportation, the packaging process is necessary. Packaging scales have lower requirements. Customers can use Richi's packaging scales, or they can save freight costs and purchase them locally.(If you don't need granulation, directly package and sell.)

PLC is designed according to the requirement of the customer. It can also control automation level.Our PLC is provided by the top international brands in the industrial automation field such as Siemens, Schneider and Delta.
