The advantages of the fertilizer extrusion granulation production line mainly include the following:
1. Production aspect
Simple process: No complex pre-treatment steps such as drying and cooling are required, and powdered or granular materials can be directly extruded into shape. The process flow is short, easy to operate and control.
Wide adaptability of raw materials: It can handle a variety of materials, such as poultry manure, sludge, straw, various fertilizer raw materials, etc. The particle size requirements for raw materials are not strict, and both 1-4mm granular materials and fine powder materials can be used, which can fully utilize various resources for production.
Product diversification: By adjusting the raw material ratio and process parameters, different concentrations and types of compound fertilizers can be produced, including organic fertilizers, inorganic fertilizers, biological fertilizers, etc., to meet different market demands. One set of equipment can produce products with multiple formulas.
Flexible production capacity: The effect of economic scale is not significant, and the range of equipment capacity is wide. From smaller to larger scales, more economical designs can be made, and the applicable capacity range is wide. The production scale can be flexibly adjusted according to market demand.
2. Quality aspect
High particle quality: The extruded particles have uniform size, regular shape, good strength and stability, are not easily broken, are easy to store and transport, and during the extrusion process, the air between the particles can be squeezed out, making the particle spacing close enough to generate various attractive forces such as van der Waals force and adsorption force, enhancing the strength of the particles.
Nutrient uniformity: Due to the extrusion granulation process at room temperature, there is no need to add chemical substances such as binders, which avoids the impact of additives on fertilizer composition and can better maintain the uniformity of nutrients in the fertilizer, which is beneficial for crop absorption and utilization.
3. Equipment and cost aspects
Less equipment investment: eliminates the need for complex processes such as drying, resulting in relatively low overall equipment investment and reduced production costs and investment risks.
Low energy consumption: It mainly relies on mechanical pressure for granulation, without the need for drying measures such as fuel and gas. Production only requires electricity consumption and a very small amount of cooling water for roller shaft cooling. The energy consumption per ton of product is relatively low, saving energy costs.
Low maintenance cost: The equipment structure is relatively simple, with fewer components, making daily maintenance and upkeep easier, reducing the frequency and cost of equipment repair and component replacement, and lowering operating costs.
4. In terms of environmental protection
Non polluting emissions: The production process does not produce pollutants such as exhaust gas and wastewater, which meets environmental protection requirements and helps enterprises achieve clean production, reduce environmental pollution, and also conforms to the basic national policy of environmental protection and the development strategy of enterprise environmental protection.
In summary, the fertilizer extrusion granulation production line has significant advantages in multiple aspects, which have led to its widespread application and promotion in the field of fertilizer production, bringing good economic and social benefits to enterprises.
