As we know, the coconut shell crushed material must maintain a certain amount of moisture during storage and transportation. Dongding has developed a set of integrated equipment for dewatering and drying of coconut shell crushed material according to processing requirements. This system has the advantages of energy saving and low consumption technology. Our company through the precise temperature control and scientific sealing technology, achieves a safe and efficient production process, clean and environmentally friendly. At present, our company can provide 3 to 50,000 tons of production lines to meet the needs of customers.
First, the material is crushed by a crushing machine, and the pulverized material is fed to a screw extrusion dehydrator through a screw conveyor, after which the moisture content can be controlled below 60% (it is not ecessary if the initial moisture is below 60%), then material was sent into the rotary drum by conveyor belt or elecator, when installation, the drum need have a 3-5 degree inclination to ensure the materials move from the upper part to lower parts smoothly, in upper part, there is a birck heating stove or coal gas producer, producing the hot air into dryer, and materials and hot air are contacted completely in the rotary drum, then wet materials are dried. The finished product discharge from the drum and cyclone is sent by the belt conveyor. After the heat exchange, the exhaust gas containing a large amount of water vapor is removed by the cyclone and discharged.
