Compared with the non calcined kaolin calcined kaolin, calcined kaolin with reduced water content, silica and alumina content increased three, the activity increases, changes in the structure, the particle size is small and uniform, compared with non calcined kaolin filled NR rubber, vulcanized low temperature characteristic curve of calcined kaolin filled NR compound consistent. Shore A hardness constant, higher tensile strength, physical properties of both non transparent sole to sports shoes industry standards.
Calcined kaolin is one of the quick method for deep processing of kaolin, kaolin will have further heating, washing and drying mill ductile step roasting, dehydration, and made it into metakaolin
The rotary kiln with heavy load and alternating speed in high temperature condition, the maintenance of the accessories and the control of the thermal system are related to the safety and efficiency of the rotary kiln operation
The key point of the maintenance of the transmission device is the lubrication, running state, dynamic detection and meshing precision of the large and small gears;
The installation accuracy of supporting device determines whether the safe and reliable operation of the rotary kiln, the operation should pay attention to the reasonable control of the gear wheel load distribution, wheel arrangement and hydraulic blocking wheel on the downward pressure and time, wheel force, tyre and shell gap.
The quality of the sealing device directly affects the thermal system and operation cost of the rotary kiln. Strengthening the routine data analysis and maintenance of kaolin rotary kiln is beneficial to the management of equipment.
Kaolin rotary kiln temperature calcination kaolin technology represents the development direction of superfine kaolin calcining technology, the calcination technology of low energy consumption, high yield, product by dehydration, decarburization whitening, stable performance.
Kaolin rotary kiln has been well developed and utilized because of its fine particle size, high precision, large processing capacity, low energy consumption per unit product, small abrasion and high efficiency.
The crushing limit particle size is small, the crushing ratio and processing capacity are large, the energy consumption per unit product is low, the abrasion is small, the efficiency is high, and the range of use is wide.
