Detailed explanation of the working principle of compound fertilizer equipment

 Zhengzhou Huaqiang Heavy Industry Co., Ltd. is professional fertilizer machine manufacturers of compound fertilizer equipment. The working principle of compound fertilizer equipment is described in detail below, and we hope to help you.

The following is a detailed description:
1) Selection of raw materials. Stirring with two mixers of compound fertilizer equipment, according to the formula operation, adding: additives, trace elements, N, P, K, etc., adding to the mixer for stirring, and alternately stirring with two mixers, which can continuously produce and improve efficiency, greatly reducing the labor intensity of people.

(2) Mixing raw materials and ingredients. The horizontal crusher, which is unique to the compound fertilizer equipment, is used for mashing and pulverizing. The pulverizer can thoroughly pulverize the added bulk materials, thereby allowing the raw materials to be completely mixed.

(3) Granulation. Granulation is a very important step in the NPK compound fertilizer production. There are also many kinds of fertilizer granulator machine. Here are: drum granulator, disc granulator, roller press granulator, and these three are the most widely used, but each has its own shortcomings.

(4) Drying the granules and increasing the hardness. The granulated compound fertilizer has formed granules, but since there is still moisture and the hardness does not meet the requirements, it must be dried by using a rotary dryer to achieve the requirements of drying and strength.

(5) Cooling granules. The dried granules are transferred to a rotary chiller for cooling, and after cooling to normal temperature, the strength of the composite fertilizer granules is further increased, and the moisture is further reduced.

(6) Screening. The cooled composite fertilizer particles will have powdery particles. The fine powder and large particles will be completely sieved out by the sifting machine. The fine powder will be returned to the mixer and mixed with the raw materials through the return belt conveyor and then participate in the granulation process again. After the large particles are pulverized, the fine powder is returned to the mixer through the same return belt conveyor. In this way, a complete production cycle is formed, and the quasi-finished product enters the coating process.

(7) Packaging. Packing is carried out by using the compound fertilizer packaging machine. After the worker puts on the packaging bag and triggers the switch, the packaging machine automatically completes the bagging, blanking and bag placement. At the same time, the feeding device is automatically and automatically fed. When the weighing weight of the weighing and weighing system reaches the set value, the feeding is automatically ended, and the operator puts on a new packaging bag to carry out the next packaging process.

The above is the detailed production process of NPK fertilizer production and the introduction of machine working principle. I hope that it can help your production and machine purchase. Our company welcomes new and old customers to visit and inquiry
