[Functions]

　　The milling drum made of stainless steel possesses the features of high precision, multiple functions, high effciency and utomation. It utilizes advanced technique, such as　　

　　pneumatic circuit, automatic control and program control. It can control heat, temperature and humidity automatically. The simple operation contributes to continuance

　　andautomation of tanning production. Leather after bating softly is not only eliminated coheres, contraction andextension and improve exterior appearance; the leather has

　　excellent surface graininess.　　

　　[Structure]

　　This machine consists of inside drum made of stainless steel, outside shell with heat-shielded layer, frame, driving component and automatic PC set which control water, electric and air.

　　1. The driving adopts braking motor and cyclic gear reducer. The drum body revolves in positive and opposite direction by five one-grouped V-belts.

　　2. It is set eight aprons around inside drum. On both ends of drum body, there is a closed circuit composed by windpipe, heating set and absorption dust set. The leather in the drum run by multiple function proguam is controlled according to the requirement of process. Dust on leather is continually removed into dust collector through wind path,

　　therefore the quality of finished leather is assured.

　　3. Relative humidity in the drum is adjusted by spraying water from time to time. The spray-water time is adjusted automatically through PC timer installed in electric box in

　　ciculatory way.

　　4. There is an exchange device, which can adjust temperature and humidity automatically. When a command of open valve in temperature and humidity control system is sent out, air in the drum will flow outside. It is necessary when both temperature and humidity control system sent out close command, the air can flow inside the drum body.
