Product strucure:

Kingcera Alumina ceramic is directly affixed on the steel plate of inner wall of equipment by high temperature resistant inorganic bond and forms a firm wear resistant layer after heating solidification. Ther product is applicable for the air (wind) powder feeding, and can be used in a high temperature in long term without aging and peeling. 

 

Clear advantages:

 

--- long lifetime

 

--- maintenance free operation

 

--- no operation interuption

 

--- no production losses

 

--- no contaminaiton of conveyed mataterial due to abrasion, mixture or oxidation

 

--- physiologically harmless, suiable for food products

 

--- smooth surface to achieve good flowability and to aviod plugs

 

--- reduced pressure losses and lower energy cost
