Organic fertilizer dryer working principle: Organic fertilizer dryer through electricity, diesel power, wind, coal, flammable material and other high heat generation power using ambient air heating, transported to the through the surrounding, and then reach the appropriate temperature for dehumidification treatment. The specific process of the fertilizer dryer is as follows: the wet material is sent to the hopper by the belt conveyor or bucket elevator, and then the feed machine of the hopper enters the feed end through the feed pipe.
The slope of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow smoothly into the dryer. The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal line. The material is added from the higher end, the heat carrier enters from the lower end, and the material is in countercurrent contact, and the heat carrier and the material flow into the cylinder together. As the cylinder rotates the material is moved by gravity to the bottom end.
In the process of moving the wet material forward in the cylinder body, the heat transfer of the heat carrier is directly or indirectly obtained, so that the wet material can be dried, and then sent out by the belt machine or screw conveyor at the discharge end. The inner wall of the cylinder is equipped with a copy plate, which is used to copy the material and scatter it, so that the contact surface between the material and the air flow is increased, so as to improve the drying rate and promote the progress of the material.
Heat carrier is generally divided into hot air, flue gas and so on. After the heat carrier passes through the dryer, the cyclone dust collector is generally required to capture the material in the gas. If it is necessary to further reduce the dust content of the tail gas, it should also be discharged after a bag dust collector or a wet dust collector.
