Material use reasonable Bangke sand dryer equipment

Box-section of sand dryer equipment, manufacturing complex, material utilization is reasonable, stiffness, help strengthen Simplified stiffness, good heat dissipation during operation. However, due to the cross-sectional shape of the complex, while the use of casting process easy to shrink cracks, blisters and other defects that can sometimes lead to the cross-sectional fracture. Drying Equipment rounded and holistic usually simplified to further simplify the manufacture, installation, and enhance Simplified stiffness, will roll group and Simplified thickened segment (Rolling trapped under section) together structure. Dryer rolling ring cross section may also be a solid rectangle, create a simple, small temperature stress. But the irrational use of materials, stiffness small (refer to the same weight dryer rolling circle), poor heat dissipation. Currently used very widely, a large multi-firing kilns and cement kilns using this rectangular cross-section roll sleepy.
The baffle wall height on the flue gas flow direction of the flame, so that the maximum temperature of the grate plate is fixed at a predetermined position on the tape. Baffle wall is too high, the flue gas toward the front of the few grate plate, rear temperature decreases; too low flue gas toward the rear, with the highest temperature shift. So, sand dryer baffle wall height should be properly designed according to the length of the grate plate, grate plate heat makes the ideal situation, the average height of the baffle wall about 200 mm and 400 mm. This spacing also need to be properly considered in the design, and with the sand dryer baffle wall designed to combine OK. High stability can most easily by the grate plate is burned to determine the location and adjust in practice sand dryer and furnace height baffle wall top to grate plate spacing.
