The impact of the granulation process of the pig manure organic fertilizer granulator on product quality is mainly reflected in the following aspects:
Particle size distribution:
Different granulation processes can affect the particle size distribution of the final product. Wet granulation usually results in a relatively uniform particle size distribution, while dry granulation may produce significant particle size differences.
Particle strength:
Wet granulation, by adding water or other liquids as binders, can increase the strength and hardness of the particles, making them more suitable for storage and transportation.
The particle strength of dry granulation is relatively low, but the energy consumption during the production process is low.
Moisture content:
Wet granulation can increase the moisture content of the product, which may affect storage and subsequent processing.
Dry granulation has a lower moisture content, but may require additional drying processes.
Organic matter content:
The granulation process may affect the conversion efficiency of organic matter in pig manure, thereby affecting the fertilizer efficiency of the product.
Wet granulation facilitates microbial activity and may promote the conversion of organic matter.
Environmental impact:
Wet granulation may generate wastewater and exhaust gas, and appropriate treatment measures are needed to reduce environmental pollution.
Dry granulation has a relatively small impact on the environment.
Production efficiency:
The production efficiency of wet granulation is usually higher than that of dry granulation because its drying and granulation processes can be carried out continuously.
The production efficiency of dry granulation is relatively low, but the energy consumption is also low.
Cost:
The production cost of wet granulation is relatively high because it requires additional energy and materials to regulate humidity.
The production cost of dry granulation is lower, but the product quality may not be as good as wet granulation.
Based on the characteristics of pig manure and the intended use of the final product, a suitable organic fertilizer granulation process can be selected to optimize product quality. For example, if high-strength particles are needed, wet granulation can be chosen; If low-cost production is required, dry granulation can be chosen. At the same time, appropriate measures should be taken to reduce the environmental impact during the production of fertilizers by organic fertilizer granulators, taking into account the requirements of environmental protection and sustainable development.
