The production line for NPK fertilizer completes all the following steps: – Crushing – Batching – Granulating – Mixing – Drying – Cooling – Screening – Coating – Packing
In short, these machines are made to lessen the production process if you make the entire NPK fertilizer manufacturing process better and faster. Consequently the one thing that you will want to do is to secure a a certain granulator for your personal fertilizer manufacturing plant. The granulator you will want may be the double roller extrusion granulator.
This particular granulator machine utilizes the technology of dry granulation to help make the fertilizer granules. It is ideal for using air to dry the pellets. The pellets which are created from this machine will not be full of temperature.
Put simply, these pellets do not need to be cooled and dried through the machines. In addition, this process eliminates the requirement for liquids or other sorts of binders. When binders are eliminated, the fertility and purity in the final product is a lot better.
Problems needing attention in the producting line of organic fertilizer
1. The risk in the process of fermentation and comminution of organic fertilizer production line mainly comes from the equipment. Such as the use of shredders, forklifts and other machinery, the need for eye and ear protection and prevention.
When using special stacking equipment, it is necessary to comply with the relevant regulations. Some dumpers contain high-speed rotary flail knives, and people and animals in contact with them should be well protected. When the mixed swing knife rotates through the stack, the material in the stack will be thrown out and become a risk factor. The equipment operators on site must understand and have protective measures.
2. Another kind of problem in the process of organic fertilizer composting is health. Animal manure, municipal sludge and other waste materials contain some pathogenic bacteria, and some of them are pathogenic to human beings.
The conventional simple prevention and control method is to let workers wear dust masks during operation and wash hands when contacting with raw materials. Ventilation measures shall be taken in places with dust, peculiar smell, harmful and toxic gases, and ventilation facilities shall be in good condition.
