Compound fertilizer production line

According some authoritative data, we know that farmers’ demand for compound fertilizer is increasing. So if you are thinking about what kind of business you should carry out. Starting a compound fertilizer production line is a good choice. Before that, you should know some information about compound fertilizer.

Compound fertilizer is a kind of chemical fertilizer containing two or more kinds of nutrient elements. And compound fertilizer has the advantages of high nutrient content, few side components and good physical properties. In addition, it plays a very important role in balancing fertilization, improving fertilizer utilization rate and promoting high and stable yield of crops.

What is the compound fertilizer production process?

First, the compound fertilizer powder should put into the static batching machine. In this way, you will get the compound fertilizer powder that has the right proportions.

Next the raw materials should be putted into double shafts horizontal mixer in strict accordance with the technical requirements of each raw material quantity. Then the belt conveyor sends the materials to cage crusher.

With the help of cage crusher, the lump materials will be crushed into powder. Fineness will meet the requirements of granulation. Then the belt conveyor can send the materials to rotary drum granulator.

During granulating, there is a water pump to offer gas and make fertilizer particles forming easily. The solid fertilizer powder after granulating will rise by the rotation of the cylinder and scroll down under the effect of gravity. After several times repetition of the same rotation, fertilizer materials gradually form. Next the belt conveyor sends the materials to rotary drum drying machine and rotary drum cooling machine.

There are also draught fans to supply hot air and cold air to rotary drum drying machine and rotary drum cooling machine respectively. After drying and cooling we can enter the screening process.

If you want your compound fertilizer more beautiful, you can use our rotary coating machine. The coating machine can beautify the materials.

In the process of screening, the qualified materials can be sent to single bucket automatic packing machine after screening, while others are conveyed back to crusher or granulator to be re-processed. Because these compound fertilizer pellets are too big or too small.

How do I prevent the caking of compound fertilizer?

Caking is a common problem in compound fertilizer production line. Many compound fertilizer manufacturers have this problem. To prevent this kind of problem, the following measures should be taken:

  1. Reasonably match the raw materials. You should mix strictly in proportion.
  2. Strictly control the moisture content of finished products to reduce water evaporation.
  3. In addition, you should also strictly control raw material particle size to improve screening effect;
  4. Using rotary drum cooling machine to lower the packaging temperature below 40 degrees.

If you don’t want to get the caked compound fertilizer, you should read these carefully.
