There are two kinds of organic fertilizer raw materials: one is livestock and poultry manure (about 2.2 billion tons of annual resources), straw (about 700 million tons of annual resources), green manure (about 100 million tons of annual resources) and cake manure (about 25 million tons of annual resources), which can be directly applied without processing, and is called basic fertilizer; The other is compost (the total annual resources are about 2.3 billion tons), biogas fertilizer, manure, and plant ash, which can be used only after processing. It is called derived resources. Before 1980, organic manure in China was mainly produced by accumulation. Since 1980, organic manure has been industrialized, mainly by stack compost, and the process of decomposition has been treated innocuously.

Solid liquid separation equipment: rotary drum screen separator: it uses the principle of reverse rotation to separate, with compact structure, reliable quality, convenient operation, simple operation, clean site and high efficiency. The 1.1 kW motor has a daily processing capacity of 50-100 T / d.

Spiral extrusion solid-liquid separator: it uses the principle of spiral extrusion to separate, with compact structure, small investment, high efficiency, low energy consumption and convenient maintenance. The 4kw motor has a processing capacity of 8-10 m3 / h per hour.

Organic fertilizer crushing equipment: crusher: the material to be crushed has high moisture content, is easy to agglomerate, and the particle size is not too fine. It is required to have low relative speed, no screen, anti adhesion and easy cleaning. The 30 kW motor has a daily processing capacity of 40-80 T / d.

Grass cutter: the materials to be crushed are of low moisture content and long fiber, with a processing length of 15-50 mm and a processing capacity of 0.5 T / h of 1.5-2.2 kW motor.

Hammer crusher: the materials to be crushed have low moisture content and are mostly waste after grain processing, such as rice husk, corn cob and cake meal. It can produce 2-10 mm and 110 kW motors with an hourly processing capacity of 8-20 T / h.

Wood crusher: the materials to be crushed are dry wood. The 15 kW motor has a processing capacity of 0.8-1 T / h per hour.

Branch crusher: the materials to be crushed are fresh wood, such as branches, flowers and grasses. The 22-55 kW motor has a processing capacity of 1-4 T / h per hour.
