Product Description

The three cylinder dryer is considered a relatively energy-saving type of dryer equipment. Currently, some improvements have been made to the original dryer, with a simple internal structure and low energy consumption, which has become a favorite of users and greatly improved labor productivity. Currently, it is mainly used in various industries such as slag, clay, coal, iron powder, mineral powder, and other mixed materials, as well as dry mixed mortar, yellow sand, and raw materials drying in chemical and casting industries.

Feature

1. The investment required for equipment is 1/6 of that of imported products from abroad.

2. The final moisture content of the material is ensured to be below 0.5%, making it the preferred product for dry mixed mortar and slag powder production lines.

3. The self insulation thermal efficiency of the cylinder can reach over 70% (traditional single cylinder dryers only have a thermal efficiency of 35%), improving the thermal efficiency by 35%.

4. Fuel can adapt to coal, oil, and gas. Capable of drying block materials, granular materials, and powder materials below 20mm.

Working principle

The materials of the three drum dryer enter the inner layer of the rotary drum from the feeding device to realize the downstream drying and the downstream drying. The materials are continuously lifted and scattered under the board reading of the inner layer to realize the heat exchange in a spiral way. The materials are moved to the other end of the inner layer to enter the middle layer for countercurrent drying. The materials are repeatedly lifted in the middle layer in a way of two steps forward and one step backward. The materials fully absorb the heat emitted by the inner drum in the middle layer, It also absorbs the heat of the middle drum and prolongs the drying time, so that the material can reach the best drying state here. The materials go to the other end of the middle layer and fall into the outer layer. The materials travel in a rectangular multi loop mode in the outer drum. The materials that achieve the drying effect quickly travel out of the drum under the action of hot air. The wet materials that do not achieve the drying effect cannot travel quickly due to their own weight. The materials are fully dried in this rectangular sheet to complete the purpose of drying.
