What is the application of cooler in NPK fertilizer manufacturing process and what is the application principle? Next, let’s learn about it together.
The cooler of the fertilizer production equipment is mainly used in combination with other fertilizer equipment through the induced draft fan. The application principle is that the air flow inside the rotary cylinder is accelerated under the suction force, and the lifting plate installed by the rotary arm is turned up to achieve The purpose of cooling. In the process of use, the machine is mainly used in the mixed production of organic fertilizer equipment and compound fertilizer.
The cooler can mix granular fertilizer at a certain temperature, and the rotary cooler can be used in conjunction with the dryer, which can greatly increase the cooling rate, thereby reducing labor intensity, and greatly increasing output. This can further reduce part of the moisture and reduce the temperature of the mixed compound fertilizer made by the rotary drum granulator. The rotary cooler can also be used for other powdery objects. The cooling equipment has a compact structure and relatively low cooling efficiency. It is relatively high, so the performance is also safe and reliable of the steel frame, and the use performance is also relatively strong.
The organic fertilizer production line is mainly used to measure the organic wastes of animal manure such as cow manure, sheep manure, pig manure, chicken manure, sludge, rice straw and corn straw in the material farm after fermentation and ripening. After crushing and screening, the organic wastes with about 30% – 35% water content, together with the raw materials of binder (bentonite and humic acid) and other components to be proportioned in the proportioning and mixing system according to the proportioning requirements (biological organic fertilizer can be produced by adding functional bacteria, and organic and inorganic fertilizer can be produced by adding nitrogen, phosphorus and potassium (the total nutrient content is less than 15%)) batching and mixing. The fully mixed materials are evenly and continuously fed into the granulator by the belt conveyor, rounded into spherical particles by the polishing and shaping machine, dried by the dryer at low temperature and large air volume (≤ 65 ℃) and then cooled, screened After coating, the finished product particles are transported to the finished product silo by belt, measured by the computer quantitative packaging system, packaged and put into storage.
