In order to make the wet materials flow into the dryer box smoothly,the angle of feeding pipe is much more bigger than normal.Heatingdrum is a rotary cylinder with a certain angle of horizontal.Materials gets into the cylinder from the higher end,and the heat-carrying agent gets from another end.That kinds of feeding method is countercurrent contact.There are shovelling plates inner the cylinder body,which ruffles materials to improve sand rotary dryer speed and promote material moves alone.

2.Two wheel chocks have much force.Check the roller and supporting belt, whether they are in parallel.In the work roller easily can deviate from their normal position.

3.Wheel gears make unnormal noise.Adjust gearing clearance of gears.Change worned gear in time,keep them in a good condition.Diverse scatter plate device in rotary drum dryer.

Raising material scatter plate device,apply to rotary drying machine large block and sticky materials.Four-lattice scatter plate device,be used on high density or hard material. This raising material board divides tube into four isolated grid,reduced dust loss.Cross raising material board,suitable for small granule fragile material.Sleeve raising material board,used in compound heat transmission dryer.Sector raising material board, minuteness and dusty material.Test the machine more than four hours to ensure all is in good condition,after installation.Screwing up bolt and lubricating it evenly after tests.The fuel consumption is affectedby fuel value, Insulation quality of product components,material moisture,the uniformity of charging materials.Stopping feeding and turning off the hot blast heater,when power outage happens.
