Continuous carbonization furnaces can be used for biomass carbonization and also for activated carbon plant.They are suitable for carbonization operations with various biomass feedstocks. Continuous carbonization furnaces can either directly feed the raw materials into the furnace for carbonization or transport them using a conveyor belt for the carbonization process.
Rotary kiln Working principle: The rotary kiln is composed of barrel, supporting device, catch wheel supporting device, transmission device, movable kiln head, kiln tail sealing device, and coal injection pipe device.The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis.

Abstract: The rotary calcination kiln for a production of Titanium dioxide (TiO 2) is a very interesting dynamical system.The titanium dioxide is mostly available in a crystalline form known as anatase. The aim of the calcination process is to produce the titanium dioxide with the rutile content around 98% that has the right pigmentary properties in contrast to the …
As the name suggests, rotary kiln bauxite is the bauxite produced by rotary kiln. There are three kinds of kilns for bauxite production mainly, rotary kiln, shaft kiln and round kiln. Comparing with other two kinds, rotary kiln bauxite is caldined more evenly, benefits from the contnuous rotary movement of the kiln body.
