Process flow of rotary cooler of organic fertilizer production line

2020-11-18

The organic fertilizer production line includes a lot of equipment. Most users are familiar with dryers, so how much do you know about coolers? Let's follow the organic fertilizer equipment manufacturer to see its production process.

The dry wet material is sent to the hopper by belt conveyor or bucket elevator, and then enters the feeding end through feeding pipe through the feeder of hopper. The slope of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow into the cooler smoothly.

The cooler cylinder is a rotating cylinder slightly inclined to the horizontal line. When the material is added from the higher end, the heat carrier flows out from the low end and contacts with the material in counter current, and some heat carrier and material flow into the cylinder together. With the rotation of the cylinder, the material moves to the lower end under the action of gravity.

In the process of moving forward in the cylinder, the hot material can be cooled directly or indirectly by heat carrier, and then sent out by belt conveyor or screw conveyor at the discharge end. The cooler meets the equipments required for biofertilizer production.

A copy board is installed on the inner wall of the cylinder of the drum cooler. Its function is to pick up and scatter the materials to increase the contact surface between the materials and the airflow, so as to increase the cooling rate and make the materials move forward. The cooling body is generally divided into cold air and so on. After the heating medium passes through the cooler, a cyclone dust collector is generally required to capture the materials carried in the gas. If it is necessary to further reduce the dust content of the exhaust gas, it should be discharged after passing through a bag filter or a wet dust collector.

The rotary drum cooler needs to be installed in coordination with the drum granulation process flow. The elevation and horizontal position are pointed out, and the installation is inclined. Generally, the inclination is 2-5 degrees (users can adjust according to their needs). The bracket and transmission frame of the machine have anchor holes, which can be installed on the concrete.
