1.Adopt the corrugated sidewall belt conveyor with big groove angle
The working principle of improving inclination angle of conveyor is that the conveyor belt forms a deep groove, and the extrusion occurs between the conveyor belt and the material, so that the friction force of the material on the conveyor belt increases. There are three types of structures: 1. The conveyor belt is L-shaped, with reinforcing cables in the middle; 2. Several sets of idlers lift the conveyor belt to form a deep groove; 3. Special idlers are used to produce extrusion between the conveyor belt and material. Increase the friction force of materials on conveyor belt. This type is also a design priority. The deep groove angle roller set of four idlers is adopted to increase the material sectional area and improve the friction coefficient between materials and conveyor belt. In order to increase the material sectional area, improve the transport capacity and increase the inclination angle of the conveyor. Roller set adopts four rollers to increase the groove angle on both sides to 60 degree. Roller bracket (four rollers) deep groove v-shaped roller set and double v-shaped forward roller set, which is composed of four equal length idlers, with simple structure and no gap at the intersection of idlers, which increases the groove depth and reduces the wear of rubber belt. There are few kinds of idlers, spare parts and easy to maintain. The maintenance cost for the belt after operation is reduced. This structure can correct the deviation of conveyor belt.
2.A blocking device is set along the whole length of the conveyor
Block materials are particularly prone to instability and rolling downward during operation, causing injury accidents. Therefore, set up to block device (i.e. welded with shaped steel). It is better to set each 30m apart. A conveyor belt designed to cushion the falling of large pieces of material.
3.The conveyor protecting wire net
There is always pedestrian space on the side of the belt conveyor. However, due to the risk of injury when large pieces of material fall, it is necessary to increase the conveyor protection wire net. Attach it to the belt conveyor carling.
With the increasing demand for coal,new high capacity and high efficiency mine increasing. The demand of big angle,large power and long distance conveyor is also increased, it will have objective social and economic benefits. The settings of above several protective device can ensure the safe and effective transportation of corrugated sidewall belt conveyor, thus improve the production efficiency.
