Exactly What Does A Fertilizer Production Line Do?

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.

Four Methods of Temperature Control for Organic Fertilizer Drying Equipment

The drying efficiency of drying equipment in organic fertilizer production line is more important to the firing temperature. The change of firing temperature directly affects the drying quality, energy consumption and refractory brick life, so it is very important to strictly control the firing temperature.

But we will find that the firing temperature will always change.
If the firing temperature becomes lower, the feeding amount of the dryer should be adjusted to reduce the material. The range of reduction is based on the predicted range of temperature reduction. According to the variation of the feeding amount and the situation in the dryer, the corresponding air and coal consumption should be adjusted in time.

When the firing temperature becomes higher and the feed rate is at a higher level, the coal should be reduced first. The extent of reduction depends on the temperature of the industrial dryer has increased, rather than rush to feed. Only to find out the reasons for the change of the firing temperature of the drying equipment, and solve it pertinently. In addition, timely report to the superior in case of any change of temperature.

(1) Sealing control of dryer. It can be partially sealed, integrally sealed or closed chamber, etc., and the dust producing point can be sealed with a sealing cover, which can greatly reduce the material scattering and dust.

(2) Eliminate the height potential energy difference of dryer. This is the main reason of dust spilling. The elimination of height potential energy difference is caused by powder drop of hopper, protective cover and chute of handling equipment. We should try our best to reduce the fall and the inclination angle of the chute. Some airtight chambers are better to cause negative pressure, which is conducive to the collection of dust.

(3) The transportation equipment with good sealing performance shall be used to reduce the height difference and inclination angle of discharge material flow, and the flow separation facilities shall be set as far as possible. It can not only enhance the configuration flexibility and efficiency of each operation room, but also reduce the scattering and dust.

(4) Use the exhaust system. In order not to let the dust bring more pollution, we can also remove the indoor dust through the exhaust system, that is to remove the indoor exhaust gas.
