How to improve lignite quality fast forward, lignite drying is a key link. Brown coal drying project in the country belong to a new industry, lignite quality mesh is a professional systems engineering, technical, quality, aftermarket indispensable Dongding dry lignite drying equipment manufacturer of professional you build quality lignite drying project Dongding to ensure strength. 

 Lignite drying equipment and technology are as follows: the raw lignite crushed by belt conveyors to feed bins, and then slide the drum dryer by its rapid large inclination guide plate oriented tilt lifting, and with the rotation of the drum and barrel the inclination of the body, is provided for since the barrel end of the tube top down to form a material screen, high-temperature flue gas from the same side with the wet material into the drying drum through the wet material to form a conductive liquid heat exchange to preheat the wet material and evaporation of the water. The same time, the high temperature flue gas temperature rapid decline in temperature drying stage after preheating the wet material, most of the water was evaporated at this stage. With the materials and the repeated mixing of the flue gas exchange until they reach thermal equilibrium to reach the water requirements of materials, the material is discharged drying drum. Inside the drum copy board strip pore structure of lignite so he took the process inside the drum, and continue to leak, both to increase the contact area of ??the lignite and the hot flue gas, to avoid, so he took a rupture caused by too high a one-time whereabouts. significantly reduce the lignite recrushing volume. Copy board between the level of scattered layout has a certain angle with the cylinder axis, both so he took a continuous lignite formation material curtain, but also make the dry material continuously forward to the discharge end, the formation of continuous drying. Are made of thin stainless steel plates to seal between the drum front head and the back-end head and the drum, the lateral plates of stainless steel tension springs and rollers outside of the ring closed, this sealing method can be high temperature, no noise, no leakage gas, is a new type of seal. After a heat exchange contains a lot of water vapor and dust exhaust after the cyclone, to get rid of most of the dust into the bag filter purification, the purified exhaust the direct discharge to form the entire drying process. Dong Ding's latest development of the lignite drying dedicated large-scale burner stove, completely solve the problem of lignite drying heat source selection troubled. Select Dongding strength of the witness.
