In the operation of moving forward, backward, directing, conversing, raising, turning, the material contacts with the hot air efficiently, thereby being dried quickly and evenly. Dry material will be discharged into star type unloader, then unload on conveyor for next operation (mixing, cooling and package). The whole process is automatically and controlled by PLC. Equipment operation only need 1-2 people per shift. This drying equipment can also be used for drying forage, distillers grain, cassave residues/pulp, corn pulp, potato dregs, soy sauce residue, soybean wastes, fruit pomace, zymophyte dregs etc. The finished production is very good raw material of organic feed for animals.
"Printing and dyeing sludge contains a large number of chemical residues, with high proportion of inherent water, is very difficult to dehydrate. Its composition is very complex, with high content of harmful substances and a certain degree of stickiness. After the mechanical filter, the sludge moisture content is still as high as 75 ~ 85%. However, the organic components in printing and dyeing sludge is very high. The calorific value of dry sludge can reach 2000kcal/kg, about 30% - 50% coal. With considerable energy use value, the dry sludge can be mixed with coal as boiler fuel, resulting in economic benefits. ZJN Drying equipment can maximize this benefits. General printing and dyeing enterprises are set up a large number of flue gas flue gas, ZJN can use the boiler flue air to dry sludge below 30% moisture. And the dry sludge will be small particles. It will greatly reduce the sludge storage and transportation costs and pollution risks. "

Sand dryer is also known as the three layers of drum dryer, three return cylinder dryers, on the basis of the single-cylinder dryer, developed and manufactured, which is an industrial dryer on non-viscous, liquid material. At present three-cylinder dryer made by Dingli company, with mature technology, through the drying of the sand, fly ash, coal, mineral materials, slag and other material, the effect is very good. Principle The sand is conveyed to silo by belt conveyor or bucket elevator, and transport to the feed end by the feeder of the silo. The inclination of the feeding pipeline should exceed the natural inclination of materials so that to facilitate sand flowing into the dryer smoothly. The rotating cylinder of the dryer is slightly inclined to the horizon. To feed the material from the higher end and the heat carrier enter from the lower end, such produce adverse contact between them .sometimes, they can be fed to the cylinder together. As the cylinder running, the sand carried to the lower side by gravity. In the process of moving forward, the wet raw material being roasted by the heat directly or indirectly to make the raw material to dry quickly, the final products discharge out by belt conveyor or screw conveyor. There is a shoveling plate installed in the dryer with the function of shoveling the materials up and down, to enlarge the contact area between airflow and materials and to enhance the efficiency and make the material running quickly. The heat carrier is hot air, the flue gas, etc. After the dryer process, It needs a cyclone dust collector to catch the items in the airflow. You should use a bag type or wet-type dust collector and afterward discharge the waste gas if you intend to further reduce the dust load of the exhaust.
