In the production line of cow manure organic fertilizer, choosing the appropriate type of granulator directly affects the quality and production efficiency of the organic fertilizer. Considering the characteristics of cow manure, such as high moisture content and abundant cellulose, the following granulators are commonly used in the production of organic fertilizers from cow manure:
The drum granulator is one of the most commonly used granulation equipment in the production of cow manure organic fertilizer. It naturally aggregates materials into balls under the combined effect of its own gravity and rotational force through a rotating drum and a suitable moist environment. The granulation process of this model is mild, especially suitable for processing high moisture raw materials such as fresh cow manure. In addition, by adjusting the angle and speed of the drum, the size and density of particles can be flexibly controlled.
2. Ring mold granulator
Ring mold granulator, also known as flat mold granulator, is suitable for processing various organic materials, including cow manure. Its working principle is to mix cow manure and other additives, and then extrude them from the micropores of the mold through high-pressure extrusion, forming a strip shape, which is then cut into particles. The particles formed by this method have a regular shape and high hardness, making them suitable for long-distance transportation and long-term storage.
Squeezing granulator is suitable for processing materials containing a large amount of cellulose and high humidity, such as insufficiently dehydrated cow manure. This machine uses a powerful hydraulic system to forcefully squeeze materials out of the mold pores, forming dense particles that reduce the cost of later drying and can retain the active ingredients in cow manure to a certain extent.
The disc granulator is another effective method, especially when dealing with small-scale production. Cow manure rolls on the inclined disc surface, and under the action of centrifugal force and its own gravity, the material gradually aggregates into spherical particles. This granulation method has good granulation effect, especially when the humidity of the raw materials is moderate.
Choose Suggestions
When choosing a cow manure organic fertilizer granulator, the following factors should be considered comprehensively:
Raw material characteristics: moisture content, fiber content, particle size, etc;
Capacity demand: expected daily or annual production;
Particle size: desired particle size and shape preference;
Budget constraints: consideration of equipment investment and operation and maintenance costs;
Environmental protection: whether low energy consumption and low emission solutions are needed;
Considering the specific characteristics of cow manure, it is recommended to give priority to drum granulators and ring mold granulators, both of which can effectively cope with the high moisture problem of cow manure while ensuring the granulation effect. Select the most suitable type of granulator based on the specific production scale and budget. In practice, it may be necessary to combine multiple granulation techniques and equipment to achieve optimal product quality and highest production efficiency.
