Conveyor belt is the index component bearing component of belt conveyor, it is the main component of belt conveyor. Its price generally accounts for 30% ~ 40% more of the whole machine price. Therefore, the selection of suitable conveyor belt, reducing the tension of conveyor belt, protecting the conveyor belt being damaged in use, facilitating the installation, replacement maintenance of conveyor belt, extending the service life of conveyor belt become the core contents of conveyor design.

The corridor of belt conveyor is mainly used to support the middle part of belt conveyor, facilitate the observation of management maintenance personnel, maintain the passage temporarily place small maintenance equipment, serve as the channel for relevant cables, lighting lines, water pipes compressed air pipelines. Corridor design must be differentiated according to its use.

There are three types of corridor: closed type, semi closed type open type. Its structure can be steel structure, concrete structure, brick concrete structure so on. Generally, the selection follows the following principles:

1. In general, a heating corridor used in heating area a, B corridor with strict requirements for rain proof moisture-proof, C corridor crossing highway overpass with important urban road shall be selected under the following working conditions. If it is closed, the safety of driving pedestrians under the corridor cannot be ensured.

2. The corridor with low requirements of rain proof, moisture-proof windproof generally adopts semi closed corridor open corridor with conveyor cover.

Various parameters to be measured for belt conveyor are as follows:

1. Characteristic parameters of adhesive tape: including elastic modulus, adhesive coefficient, impact resistance, etc.

2. Motion parameters: including displacement, velocity, acceleration, slip, etc.

3. Mechanical parameters: including belt running resistance, tension, motor power, etc.

4. Vibration parameters: including belt transverse vibration amplitude, frequency, etc.
