As a consequence of the rotation with the screw, plastic particles within the barrel deformation and squeeze, produces heat and temperature rise of from time to time more than plastic particles of plastic required, kiln dryer, even after turning off energy and they have not ceased, and beyond the scope of needs. At this point, in the event the machine cooling method out of balance, like cooling fan power shortage, harm, causing the barrel temperature handle, produces plastic chemical imbalance. Foaming agent directly in to the concrete or mortar mixer blender, foaming agents and mortar or concrete mix to generate foam. The cooling machine has obvious characteristics of very simple and compact construction, steady and dependable efficiency, mineral ore, simple operation, easy upkeep, roller dryer, higher cooling efficiency and excellent adaptability. The cooling machine is also known as the rotary drum cooler, which can support the rotary kilnto form a complete production system. In the actual production process, primary jaw crusher, the cooling machine is mainly used to cool the materials with a certain temperature and particle size by supporting the dryer machine, crushing mill, which can greatly improve the cooling rate, reduce labor intensity and improve production as well as further removing part of the water and reducing the grain temperature of materials. Soon after heat exchanging, the exhaust gas might be introduced to Rotary kiln, therefore to enhance the thermal efficiency of your total technique.Cooling machine also can be used as the fertilizer production line, which can cool the fertilizer with the heat to one ordinary temperature, impact breaker, and the mutual coordination of cooling machine and dryer can greatly enhance the speed of being cool, which can decrease the labor strength and improve the output. High-pressure air flow in the cooler section, the air pressure of the cooling air is high, the air volume is not great, its exhaust gas as...
