What is the working principle of the chain compost turning machine?

 The core working principle of the chain compost turning machine is: the chain drives the scraper/chain plate to perform a circular motion, forcibly grabbing, lifting, and throwing the fermented material forward, achieving sufficient contact between the material and the air, and simultaneously completing the displacement of the material and the renewal of the compost pile. This provides sufficient oxygen for aerobic fermentation and accelerates the decomposition of organic matter.

Its key process logic can be broken down into three points, precisely matching the fermentation needs of organic fertilizers and other materials:

1. Forced turning and mixing: The chain plate (or chain with scrapers) penetrates into the material pile, using the traction force of the circular transmission to sequentially grab and throw the bottom and middle layers of material upwards, breaking up the compacted layers and preventing localized anaerobic decomposition.

2. Oxygenation and heat dissipation: During the throwing process, the material forms sufficient convection with the air, allowing a large amount of oxygen to be incorporated into the material, while simultaneously carrying away the heat generated by fermentation. This controls the pile temperature within the suitable decomposition range of 55-65℃, killing pathogens and insect eggs.

3. Uniform decomposition + displacement: In the composting process of the bio organic fertilizer produciton line, the material is pushed forward a certain distance (matching the layout of the fermentation workshop), achieving a continuous process of "turning, decomposing, and advancing," eliminating the need for additional manual material handling and improving fermentation efficiency.

This principle is suitable for large-tonnage, high-moisture organic fertilizer fermentation scenarios, especially suitable for trough-type fermentation processes. It is a core composting and fermentation equipment in large-scale organic fertilizer production, effectively shortening the fermentation cycle (usually 15-25 days) and improving the uniformity and maturity of the finished fertilizer.

Maintenance points of organic fertilizer equipment

Image
  The maintenance of  organic fertilizer equipment  is the key to ensure its long-term stable operation. The following are some key points of  organic fertilizer equipment   maintenance: 1. Regular cleaning: The residue and dust on the equipment should be cleaned regularly during the use of the equipment, especially in the transmission parts and sealing parts, to avoid premature wear and failure of the equipment. 2. Lubrication maintenance: Add lubricating oil to the transmission parts and friction parts of the equipment regularly to reduce the coefficient of friction and ensure the normal operation of the equipment. 3. Fastening check: Check whether the connection bolts, nuts and oil drain plugs are loose to ensure the stability and safety of the equipment. 4. Electrical performance testing: Regularly test the electrical system, including power supply voltage, power plug and socket, etc., to ensure the normal operation of the electrical system. 5. Temperature m...

Promoting effect of organic fertilizer equipment on straw fermentation

Image
  The promoting effect of  organic fertilizer equipment   on straw fermentation is mainly reflected in the following aspects: 1. Improve fermentation efficiency:  Organic fertilizer production line   through high temperature fermentation and mechanical flipping, accelerate the decomposition of cellulose, hemicellulose and other organic materials in straw, shorten the fermentation cycle. 2. Optimize fermentation conditions: By adjusting temperature, humidity and other parameters, fermentation conditions can be further optimized to improve the quality and yield of organic fertilizer. 3. Reduce pests and diseases: In the fermentation process, high temperature can kill pathogens, weed seeds and roundworm eggs in the straw, and produce bioorganic fertilizer with strong stability and complete nutrient types. 4. Improve soil structure: Organic fertilizer is rich in organic matter and a variety of trace elements, which can significantly improve soil structure, enhance s...

The equipment of Tianci fertilizer machine manufacturer is solid and durable, and NPK fertilizer granulator is suitable for different kinds of raw materials. There are many advantages in using our complete set of organic fertilizer production line equipment to make particles. 1. The double screw horizontal mixer makes the materials fully mixed, thus improving the mixing uniformity. The machine adopts a novel rotor structure, the minimum clearance between the rotor and the bright body can be adjusted to close to zero, which effectively reduces the residual amount of materials, and can break large materials. The overall structure is more reasonable, the appearance is beautiful, and the operation and maintenance are convenient.  2. The compound fertilizer crusher effectively solves the problem that the compound fertilizer raw materials are easy to absorb moisture and agglomerate, and makes the next step of the rotary drum granulator more convenient. The high-strength wear-resi...
