How to Reduce Material Blockage in Organic Fertilizer Horizontal Mixers?

 Reducing material blockage in organic fertilizer horizontal mixers requires attention to three aspects: feeding, equipment adjustment, and maintenance:

1. Controlling Feeding Conditions: The moisture content of raw materials must be strictly controlled between 20% and 30%. Excessive moisture easily leads to clumping and sticking; pre-drying or adding dry materials can help. Large pieces of material (diameter > 5cm) must be crushed before feeding to prevent them from getting stuck between the mixing shaft and the drum wall. Maintain a uniform feeding speed and install a spiral pre-feeder to avoid excessive material feeding at once, which can cause instantaneous accumulation.

2. Optimizing Equipment Structure: Install a grate (8-10cm aperture) at the mixer inlet to intercept large impurities; adjust the mixing shaft blade angle to 45° to enhance pushing force; line the drum wall with stainless steel plates where material tends to stick to reduce adhesion; install an electric gate at the discharge port, which opens intermittently according to the mixing progress to prevent backflow caused by poor discharge. 3. Routine Maintenance and Operation: After each shutdown, clean the residual material inside the drum, especially the blade roots and corners, to prevent hardened clumps. Check blade wear weekly; replace blades when wear exceeds 1/3 to avoid material blockage due to reduced pushing force. Operators must monitor current changes in real time; if the current suddenly increases (exceeding the rated value by 10%), immediately stop the machine and investigate to prevent material jamming and equipment damage.

Through these measures, the probability of material sticking, accumulation, and jamming can be significantly reduced, ensuring continuous operation of the organic fertilizer equipment.

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...

How to ensure the safe operation of organic fertilizer equipment

Image
  To ensure the safe operation of  organic fertilizer equipment , it is necessary to start from many aspects such as equipment management, personnel training, operation process and emergency measures. Here are some key measures: 1. Regular inspection and maintenance: The equipment should be checked and maintained regularly to ensure that all components are in good condition. In particular, electrical systems, transmission components and safety devices need to ensure their normal operation. 2. Equipment update and transformation: timely update of old equipment, modernization, improve the safety and reliability of equipment. 3. Safety training: Operators must receive training on equipment operation procedures and emergency measures to ensure that they are familiar with equipment performance and safety requirements. 4. Protective equipment: The operator must wear personal protective equipment such as work clothes, safety helmet and protective glasses. 5. Correct starting procedur...
