Drying Process Of High-Moisture Materials

When the machine is working,High-Moisture Materials the hot air flow is sucked into the inner cylinder of the dryer under the suction of the exhaust fan. The wet material enters the outer wall of the inner cylinder and is pre-dried first.High-Moisture Materials The material plate is lifted up to carry out sufficient heat exchange with the hot air flow,High-Moisture Materials while moving forward. Similarly, after the material enters the middle and outer cylinders in sequence,High-Moisture Materials the material is lifted by the lifting plate and evenly spread on the outer wall of the middle and outer cylinders. As the cylinder rotates slowly,High-Moisture Materials the material can experience a longer residence time in the annular space Finally,High-Moisture Materials it flows to the middle outlet end along the guide discharge plate on the outer cylinder wall and the inner cylinder, and is discharged through the discharge valve,High-Moisture Materials and the exhaust gas is drawn into the dust collector through the exhaust pipe on the upper part of the discharge hood.

It can be seen from the drying process of the above materials that the materials are directly dried by the hot air, and indirectly dried by the middle and inner cylinders. From the principle of the dryer,High-Moisture Materials it is very reasonable and scientific. The outer cylinder of the low temperature section has a thermal insulation effect on the inner cylinder of the high temperature section,High-Moisture Materials and the total heat dissipation area of the equipment is reduced by 50%-60% relative to the single cylinder dryer. High-Moisture Materials The investment required for equipment is 1/6 of the foreign imported products.High-Moisture Materials The final moisture of the material is guaranteed to be below 0.5%, and it is a product of dry-mixed mortar and slag powder production line.High-Moisture Materials The thermal efficiency of the self-insulation of the cylinder is up to 80% (the thermal efficiency of the traditional single cylinder dryer is 35%) and the thermal efficiency is increased by 45 percentage points. Fuel can adapt to coal, oil,High-Moisture Materials gas. It can bake materials, granules and powder materials under 20mm.
