Working Principle of Drum Organic Fertilizer Dryer

Image
  The  drum organic fertilizer dryer   is a key drying equipment in the  organic fertilizer produciton line , mainly used to reduce the moisture content of fermented organic fertilizer to meet the standards for granulation, storage, and transportation. Its working principle revolves around two core aspects: heat exchange and material tumbling and conveying. During the operation of  fertilizer produciton machine , the fermented wet organic fertilizer is fed into the inclined rotating drum through the inlet. The drum is driven by a motor and rotates slowly.  Internal baffles rotate with the drum, continuously lifting and scattering the material, creating a uniform material curtain inside the drum. Simultaneously, high-temperature hot air from the hot air furnace enters the drum from either the inlet or outlet end, contacting the scattered material in a counter-current or co-current flow. During this contact, the heat from the hot air is rapidly transferred to...

Fertilizer Horizontal Mixing Machine Production Quality Testing Methods

Image
  The  fertilizer horizontal mixing machine , as a key mixing equipment in  organic and compound fertilizer produciton line , directly determines the uniformity of fertilizer nutrients.  Testing should focus on three core dimensions: mixing uniformity, equipment operational stability, and material adaptability, to ensure it meets the needs of large-scale production. Mixing uniformity is the core testing indicator and can be tested using the "tracer method": a quantitative amount of an easily detectable tracer such as potassium sulfate is added to the raw materials in proportion. After mixing for a set time, samples are taken from three positions (front, middle, and back) at the mixer's discharge port. The tracer content in each sample is determined through chemical analysis, and the coefficient of variation is calculated. A coefficient of variation  ≤ 5% is considered acceptable. If it exceeds the standard, the mixing paddle speed needs to be adjusted or the mix...

How to Choose the Right Organic Fertilizer Double Axis Mixer

Image
  Choosing a suitable  organic fertilizer double axis mixer  requires considering three core factors: raw material characteristics, production capacity requirements, and finished product uniformity.  This should be combined with an assessment of equipment configuration and practicality. The specific points are as follows: 1. Matching Raw Material Characteristics For high-fiber, easily tangled raw materials such as straw and sawdust, prioritize mixers with paddle blades equipped with cutting knives to shred fibers and prevent clogging; for highly viscous raw materials such as fermented manure and sludge, choose models with wear-resistant and non-stick coatings on the paddle surface to reduce material buildup; if mixing bacterial agents and inorganic additives, select equipment with variable frequency speed control to reduce rotation speed and prevent bacterial deactivation. 2. Matching Production Capacity For small-scale  bio organic fertilizer produciton lines ...

What Factors Affect the Mixing Performance of a Double Axis Mixer?

Image
  The core factors affecting the mixing performance of an  organic fertilizer double axis mixer  are divided into three categories: raw material characteristics,  fertilizer production machine  parameters, and operating process.  Specifically: 1. Raw Material Characteristics ◦ Raw material particle size and ratio: If the particle size difference between coarse and fine raw materials is too large (e.g., uncrushed straw mixed with finely decomposed manure), stratification and segregation will occur, significantly reducing mixing uniformity; when the ratio of organic raw materials to inorganic additives and microbial agents is significantly different, a longer mixing time is required to achieve uniform mixing. ◦ Moisture content: High moisture content (exceeding 35%) easily causes clumping, making it difficult for the mixer blades to break up the clumps; low moisture content (below 20%) results in loose material, leading to "empty mixing" and preventing the fo...

What are the key points of pre-processing before NPK blending fertilizer production line?

Image
  The core points of pre-processing before  NPK blending fertilizer produciton line  are to ensure uniform particle size, controlled moisture content, and removal of impurities.  Specifically: 1. Raw material screening and impurity removal: Basic raw materials such as urea, potassium chloride, and monoammonium/diammonium phosphate are screened to remove impurities such as stones, metal fragments, and packaging bag fragments. This prevents damage to the conveying and mixing components of the  NPK blending machine  and prevents impurities from affecting the quality of the fertilizer product. 2. Particle size matching: Different raw materials are crushed to a uniform particle size range (usually 2-4mm). Excessive differences in particle size can lead to stratification during the blending process, affecting the uniformity of fertilizer efficacy; for raw materials that are prone to caking (such as urea and ammonium chloride), arch breaking and crushing treatment...

What is the capacity of a double roller press granulator production line?

Image
  The capacity of a  double roller press granulator produciton line  varies considerably, mainly depending on the equipment model, roller diameter and width, material characteristics, and process configuration. The capacity of a single line is usually between 0.5 and 20 tons per hour. Capacity Classification: 1. Small-scale production line: Suitable for small organic fertilizer factories or laboratories, with a roller diameter of 200-300mm. When processing fermented manure and straw-based organic fertilizers, the capacity is 0.5-2 tons/hour; when processing NPK dry powder mixtures, the capacity is 1-3 tons/hour, with a daily output of approximately 8-48 tons. 2. Medium-scale production line: With a roller diameter of 350-500mm, this is the mainstream choice for organic and compound fertilizer factories. The organic fertilizer capacity is 3-8 tons/hour, and the NPK compound fertilizer capacity is 5-10 tons/hour, with a daily output of up to 40-160 tons, meeting regional ma...

Development Prospects of Organic Fertilizer double axis Mixers

Image
  The development prospects of  organic fertilizer double axis mixers  are generally positive. Driven by policies, market demand, and technological advancements, the industry is moving towards intelligent, energy-efficient, customized, and green low-carbon solutions, with an average annual growth rate of approximately 8%-12%. At the policy level, the promotion of resource utilization of livestock and poultry manure, the substitution of organic fertilizers for chemical fertilizers, and the "dual carbon" goals are driving the need for improved pretreatment and mixing accuracy in organic fertilizer production. Twin-shaft mixers are rapidly gaining market share due to their advantages. In the market, high-value-added products such as bio-organic fertilizers and compound microbial fertilizers are experiencing annual growth rates exceeding 18%.  Coupled with the expansion of small and medium-sized organic fertilizer plants and the upgrading needs of large-scale  bio o...
