The cow and sheep manure organic fertilizer rotary drum granulator is a commonly used organic fertilizer granulation equipment, and its granulation process mainly involves multiple steps such as raw material preparation, granulation, drying, and cooling. The following is the detailed granulation process flow of the drum granulator for cow and sheep manure organic fertilizer:
Raw material preparation:
Pre treatment: Firstly, it is necessary to pre treat cow and sheep manure, including steps such as crushing and mixing. The collected cow and sheep manure will be crushed to the appropriate particle size by a grinder, and then mixed with other organic materials (such as straw powder, sawdust, etc.) and necessary nutrients (such as nitrogen, phosphorus, potassium) to adjust the physical properties and nutritional composition of the fertilizer.
Moisture regulation: Adjust the moisture content of the mixed raw materials to a suitable range for granulation, usually 25% to 35%. Excessive or insufficient moisture content can affect the granulation effect.
Granulation:
Working principle of rotary drum granulator: The cow and sheep manure organic fertilizer rotary drum granulator uses a tilted rotating cylinder, and the material forms particles through rotation and rolling inside the cylinder. Spiral thrusters are usually installed inside the cylinder to promote the rolling of materials and the formation of particles.
Granulation process: The pre treated raw materials are fed into the feed inlet of the rotary drum granulator, and through the rotation of the cylinder, the materials roll internally, gradually forming uniformly sized particles. The inclination angle, rotational speed, and internal structure design of the drum can all affect the formation of particles.
dry:
Drying purpose: The granulated particles need to be dried by a dryer to reduce their moisture content, improve their stability and strength, and facilitate subsequent storage and transportation.
Drying process: The particles are transported by a conveyor to a dryer, where the moisture content of the particles is evaporated by hot air or other heating methods until the desired moisture content is achieved.
Cooling:
Cooling purpose: The dried particles need to be cooled to room temperature to avoid affecting the quality of the fertilizer due to high temperature, and to facilitate subsequent packaging and storage.
Cooling process: The particles are cooled by a cooling machine, and the temperature of the particles is reduced to a safe range through natural cooling or forced air cooling.
Screening and packaging:
Screening: Use a screening machine to screen the cooled particles, remove unqualified particles, and ensure the consistency and quality of the product.
Packaging: Qualified particles after screening are packaged for easy storage, transportation, and sale.
Through the above process flow, the cow and sheep manure organic fertilizer rotary drum granulator can convert organic waste such as cow and sheep manure into high-quality organic fertilizer particles, which not only improves the physical properties and nutritional components of the fertilizer, but also realizes the recycling of resources, reduces environmental pollution, and meets the requirements of modern agricultural sustainable development.
