Faeces from livestock and poultry farming will cause environmental pollution if they are discharged unreasonably. However, manure is a kind of resource when it is used as organic fertilizer for agricultural planting. The application of chemical fertilizer in agricultural planting will result in the decline of soil organic matter and the aggravation of agricultural non-point source pollution. Livestock manure is an important source of soil organic matter. Making use of organic fertilizer can not only effectively solve the problem of farming pollution, but also improve the content of soil organic matter and reduce the loss of nitrogen and phosphorus from planting.
Organic fertilizer crusher is an important equipment in organic fertilizer production. Different types of crusher are needed in different production stages, and the role of crusher on organic fertilizer materials is different. The following is a detailed description of the crusher used in each step of organic fertilizer production.
Half wet material crusher is a special equipment for organic fermentation composting, straw mud carbon, rural straw garbage, industrial organic garbage, chicken dung, cow dung, sheep dung, pig dung, duck dung and other high-humidity fermentation materials crushing process. The moisture allowable value of bio-fermentation organic fertilizer material reaches 25-50%, and the grinding particle size meets the requirement of granulation. It can also be adjusted in a certain range according to the needs of users. It can grind hard materials such as limestone, mixture, gypsum and slag in organic fertilizer raw materials, and is mainly used for granulation after organic fertilizer fermentation.
This machine is an ideal machine for fertilizer production and processing. The adaptability of raw materials is wide. After crushing, the raw materials are fermented. The fermentation efficiency of organic fertilizer is high and the ripening effect is good.
a)Rack part: All mechanical operations are inseparable from a solid rack. The machine frame is all welded by high carbon steel plate and channel steel, and through strict product certification and specific technical requirements, to achieve the purpose of the machine.
b)Rotor crushing part: Rotor of the machine is with innovative structure and reasonable design. We adopts the upper and lower sets of rotor blade as the broken part, so the crushing effect is twice bigger than the other products. Materials enter into the crushing chamber through the inlet, then continuous grind by the double blade and the broken plate, so that the materials to achieve granulation requirements.
c)Crushing plate adjustment device: By adjusting the distance between the broken plate and the rotor blade, the fineness and output requirement of the crushing material can be determined.
Transmission connection part: The machine uses a flexible belt to drive. It is driven by the motor to pulley, belt, then directly transmit to the spindle, rotating the spindle at a high-speed, finally achieve crushing effect.
Chain crusher is a product commonly used in the production of organic fertilizer and compound fertilizer. It is suitable for the crushing of medium-sized materials before fertilizer granulation and the crushing of returned materials. The crusher grinds organic fertilizer into finer powder to improve the quality and efficiency of organic fertilizer production. The main working parts of the crusher are the rotors with steel ring chains. The chain is made of high strength wear-resistant cemented carbide, which ensures its wear resistance. The broken materials are uniform and not easy to adhere to the wall. Its main characteristics are as follows:
1. The machine is easy to use, high efficiency, large production capacity and simple maintenance. Suitable for crushing all kinds of bulk fertilizers and other medium hardness bulk materials.
2. The crusher can crush the non-dried 14% water content, 6% free acid calcium phosphate fertilizer and a variety of scaly armour compound fertilizer products.
3. The machine overcomes the shortcomings of material bonding to the inner wall of the shell, which makes production impossible. Horizontal crusher makes the crushing process in the production of phosphate compound fertilizer achieve continuous production and improves production efficiency.
Straw crusher can crush corn straw, straw, peanut skin, beanstalk, flowers and other burning residues. It avoided the burning of crop straw, protected the environment, and effectively developed renewable energy. Before organic fertilizer fermentation, straw and other materials need to be crushed, so that the fermentation speed is faster.
1. The product is reasonable in design, reliable in manufacturing quality, simple in structure, it’s easy to operate, small in size, small in floor space, and labor-saving.
2. The design of fully automatic control electric heating device can adjust the dry humidity of materials at will, ensure the stability of material molding, and improve work efficiency.
3. The main parts of the products are wear-resistant materials for special treatment, which can be continuously pressurized and durable.
4. It is applied to all kinds of biomass (corn straw, straw, straw, rice straw, rice husk, peanut shell, corn core, twigs, leaves, sawdust and other agricultural products as raw materials or wood waste).
