China's coal resources are abundant, and there are many coal washing plants. In the processing of coal washing, a large amount of coal slime is produced. These coal muds are of high humidity and high viscosity and are difficult to handle. However, if the slime is dehydrated with a slime dryer and then made into industrial coal, its combustion value helps save coal. This not only solves the problem of disposal and marketing of slime, but also reduces pollution of the surrounding environment , hence proven to be the most effective way to recycle slime.
In order to build an automated slime drying line, the energy-saving company China ZJN has engineered a series of dryers after 30 years of painstaking research on thousands of samples.The techs include treating materials of“high humidity and high viscosity”, dryers to treat sludge, solid waste and hazardous waste, “Rotary-harrow Material-crushing Triple-phase Multi-loops”, the utilization of boiler exhaust heat, and the low-humidity and high-volume air, featuring more than 100 patents exclusively owned by China ZJN.Its national patent technology is the ideal for processing high-humidity and high-viscosity coal slurry in large quantities today, completely ending the worldwide problems of sticking, clamminess and blockages in the drying of slime.
The “Rotary-harrow Material-crushing Triple-phase Multi-loop” slime dryer has reached the advanced level at home and abroad and can be widely used in drying of slime for large and medium-sized coal enterprises. The stable,harmless, volume-reducing treatment and resourcification of slime has changed the single business model of coal enterprises, which is the key for them to reverse losses to profits.
