Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a rotary kiln feeding and lifting device. Background Art

[0002] Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the different materials they process. Cement kilns are mainly used to calcine cement clinker and are divided into two categories: dry process cement kilns and wet process cement kilns.

[0003] The feed end of the rotary kiln is higher than the discharge end, so that the material can move from the feed end to the discharge end during rotation. In the existing rotary kiln, during the cement production process, the cement raw materials are transported to the top of the feed end of the rotary kiln through an auger. The cement raw materials are squeezed during the transportation process and are easily adhered to each other and agglomerated, affecting the production quality of cement. Therefore, we propose a rotary kiln feed lifting device. Utility Model Content
