The rotary drum granulator can process various types of raw materials, including:
Organic materials:
Such as animal manure (chicken manure, pig manure, cow manure, etc.), crop straw, garden waste, food processing by-products, etc.
These raw materials usually contain abundant organic matter, and after appropriate pretreatment (such as drying, crushing, mixing), they can be used to produce organic fertilizers.
Inorganic materials:
Inorganic salt fertilizers such as phosphate, potassium, ammonium sulfate, etc.
These inorganic raw materials usually have good water solubility and can be used directly as raw materials or mixed with organic materials to improve the physical properties and nutritional composition of fertilizers.
Compound fertilizer:
Mixing organic and inorganic materials in a certain proportion and processing them through a rotary drum granulator can produce organic-inorganic composite fertilizers.
This compound fertilizer combines the advantages of organic and inorganic fertilizers, providing both abundant organic matter and necessary inorganic nutrients.
Biodegradable materials:
Biomass waste, biodegradable plastics, etc. can be used to produce biodegradable granular fertilizers after appropriate treatment and formula adjustment.
Special raw materials:
Industrial by-products such as sludge and slag, after appropriate pretreatment, can also be used as raw materials for granulation.
additive:
In order to improve the shaping effect and nutritional value of particles, appropriate additives such as binders, wetting agents, preservatives, etc. can be added.
When using a rotary drum granulator to process raw materials, it is necessary to consider the physical properties of the raw materials (such as particle size, moisture content, viscosity, etc.) to ensure that the raw materials can be smoothly formed during the granulation process. For some special raw materials, pre-treatment may be necessary, such as drying, crushing, or mixing, to meet the working requirements of the rotary drum granulator. In addition, the chemical properties of the raw materials (such as pH value, salt content, etc.) can also affect the granulation process and the quality of the final product. Therefore, when selecting raw materials, it is necessary to comprehensively consider their availability, economic benefits, and environmental impact.
