Today,ZhongBo Industry and Mining Machinery Co.,Ltd to tell you about the belt tensioning operation.

      Any conveyor belt are likely to have several types of elongation or extension. Belt tensioning operation, as follows:
This elongated structure elongated knitted fabric type is mostly due to the use of a fabric rather than the raw material caused. In ordinary knit, the bent warp when the applied load will be straightened, causing the belt elongation, some of which can not be elongated restitution.
This is the starting elastic elongation acceleration or braking deceleration appears on the belt portion extended. The applied tension or stress relief after this stretch almost completely restitution.
Permanent change in length comprises a permanent change in length of the base fiber structure caused by the elongation length change, but also including some non-elastic elongation and elongation recovery of part of the structure.
Belt tensioning stroke depends on the following factors:
Whether there is a trial run using mechanical joints period. In the production before the end of vulcanized joints can easily eliminate any non-restitution length change. Starting or braking. Direct starting and braking desired tensioning stroke ratio in a controlled acceleration or deceleration start to be greater. The conveyor belt elongation and elongation properties. Loaded conveyor start and stop frequencies.
Tensioning device shall have sufficient stroke to accommodate fluctuations in acceleration or deceleration, the tensioning device without touch bezel. Tensioning device should have the number of "available for use" reserve conveyor belt, which in the event of a fault may need to use two connectors to access a conveyor belt. In addition, should also adapt belt tensioning stroke elongation or contraction caused by the change in length.
