High Capacity Industrial Drying Equipment for Dehydrating Coal Sawdust Sand
Introduction:
Industrial drying equipment is widely used in agriculture, forestry, construction, metallurgy, chemical and cement-making industry. It is applicable for sawdust, coal, sand, gypsum, slag, sludge, etc.
Working Principle:
The main body of drying machine is a cylinder at a certain gradient with horizon. The cylinder is drove by gear at a speed of 2-6r/min. The general gradient of cylinder is about 1°-5°. Materials enter cylinder by the upper end. As the cylinder rotates, materials flow to the lower end under gravity and get discharged. During this period, materials get thorough contact with hot air, moisture inside gets vaporized. Due to the drying machine operates under negative pressure, the inlet and outlet both adopt sealing device to avoid air leakage.
Features:
1. We adopt combined type of lifting device to overcome the “air tunnel” phenomenon. High heat efficiency, energy consumption is reduced about 20%.
2. Different types of furnace for actual condition: high temperature boiling furnace, coal power spraying furnace, coal furnace.
3. Pin-changeable gear replaces the traditional cast steel gear. This saves the investment and also reduces maintenance cost and time.
4. Adoption of central control system to realize management by computer for enterprise.
