Brief introduction:
Cooling machine are commonly used in agricultural production, such as cooling hot material from kiln production lines. Common are single cylinder cooling machine, also known as drum, drum cooler. In this It is widely used in compound fertilizer production line .

Working principle:
1.Composition and structure:Rotating cylinder, gear, gear wheel, drag rollers, pinions, a gate, lifting plate, reducer, motor, fan, etc.
2.Working principle:Hot material conveyed by vibrating feeder to feed hopper ,then through a feed pipe gradient to feed end,to ensure material flow smoothly ,the angle of feed pipe must be greater than the material's natural inclination.Cooling machine is a rotating cylinder slightly inclined to the horizontal. Add material from the upper end, the heating medium flow out from the lower end, counter-current contact with the material.While some model of cooling machine ,which heating body and the material are flow into the cylinder at same time.

tubular cooler is one of most important equipment in rotary kiln system,it is applicate to lower 1000-1200 Celsius degree clinker to 200 Celsius degree,to improve quality and grind ability of material. And the hot air after cooling material is enter the kiln as a secondary circulating air,improves the thermal efficiency of furnace.
