The production process of Organic fertilizer is mainly to mix the organic solid waste with water content less than 60% with auxiliary materials (plant straw, etc.), microbial fermentation agents, etc., and make it fully decomposed, sterilized, deodorized and dewatered through pool type aerobic continuous fermentation. The moisture content of the decomposed material is generally 30-35%. After screening and magnetic separation, it can be directly used to produce spherical Manure or powder Manure after further drying. Process introduction: pour the raw materials into the Organic fertilizer mixer for mixing, mix them evenly and then crush them, and then input them into the Organic fertilizer granulator with a belt conveyor; After granulation and forming, it is sent to the dryer for drying, and then sent to the cooler for cooling through the elevator or belt conveyor. The water content reaches below 6%. After cooling, it is screened. Large particles are crushed into fine materials through the return Organic fertilizer grinder, and the fine materials enter the disk granulator. The coarse returned materials enter the granulator after crushing, and the finished products are directly packaged.
The drum screen is a common equipment in the production of Organic fertilizer and compound fertilizer. It is mainly used for the separation of finished products and returned materials, and can also realize the classification of finished products, so that finished products can be classified evenly. Adopting a combination screen, it is easy to maintain and replace. The machine has a simple structure, convenient operation, and stable operation.
What are the characteristics of drum screening machines?
The drum screening machine is a relay operated vibrating screen, which is a new generation of self-cleaning screening equipment after the ordinary mesh drum screening produced by major domestic companies. It is widely used for screening various solid materials with particle sizes less than 300mm. It has many characteristics such as high screening efficiency, low noise, small dust emission, long service life, small maintenance volume, and convenient maintenance. Its screening capacity is 60 tons/hour to 1000 tons/hour. The comprehensive utilization of electricity (mainly circulating fluidized bed boilers), which mainly burns low-quality coal, has rapidly emerged in China. Fuels mainly composed of coal gangue and coal slurry often have characteristics such as stickiness, wetness, dirt, and impurities. The coal conveying system generally suffers from clogging of the screening machine, low screening efficiency, high crusher wear, and high energy consumption.
