May 7, 2014 (Newswire) - Rotary drum is an important component of belt conveyors, rotary plays an important role to transfer the power from driving device to conveying belt. Rotary drum is consist of rotary drum shaft, block of shaft, hub, auxiliary board and shell of drum. Only does the every components of rotary drum work together efficiently, the whole driving process are effective, thus, the section of rotary drum is becoming much essential for belt conveyors in conveying industry.
1. Driving rotary drum and redirection drum
According to purposes in usage of belt conveyors, the rotary drums can be varied driving rotary drum and redirection drum, the driving rotary drum is used for conveying power, and the redirection rotary drum is utilized to redirect the ways of conveying in assembling the end of belt conveyors. The surfaces of driving rotary drum is covered with rubber and ceramic in order to increase the friction between the rotary drum and conveying belt.
2. Exterior driving rotary drum and interior driving drum
In terms of driving types, the rotary drum is classified in exterior driving rotary drum and interior driving drum. As for the exterior driving rotary drum, the driving device is equipped into the external surface of rotary drum, the reducer is connected with shaft of drum. But ,for the interior driving rotary drum, the driving device is put on the internal surface, if the reduce is into rotary drum,that is also called as gear drum which is much suitable for large powder of belt conveyors.
3. Light rotary drum, medium rotary drum and weight rotary drum
On the basis of bearingsЎЇ diameter and burden, the rotary drums is divided into Light rotary drum, medium rotary drum and weight rotary drum. If the hole diameter is from 50mm to 100mm, the rotary drum is called light rotary drum, the structure between shaft and hub is adopted interference fit, which is used for driving rotary. To the medium rotary drum, the hole diameter is in between 120mm-180mm, which is employed ring locking connection. With regard to weight rotary drum, besides the ring locking connection, the auxiliary board and drum shell are cast-weld.
From the introduction above mentioned, we can draw a conclusion that the different belt conveyors are applicable for different types of rotary drums, but which elements are effecting the selection of the rotary, we can analyze the much more crucial diameter of rotary drum, that includes the twist ability of conveying, the frequency of conveying belt, the maximal or average pressure between conveying belt and face of rotary drum and so on. Varying different purpose from different rotary drum.
The conveyors we supplied are high quality and reasonable price to customized requires for all customers, including curve dynamic roller conveyor and straight roller conveyor for your different needs in food processing industry.
