The corrugated sidewall belt conveyor is quickly accepted by the majority of users because of its advantages such as large conveying inclination, large conveying capacity, small floor area, simple structure, flexible distribution, reliable operation and convenient maintenance. For conveying small particles, good mobility, dry and requirements in the conveying process particles are not damaged finished materials, the selection of edging machine is very appropriate, but because of its leakage, will cause a lot of problems such as transport capacity decline. The following measures are proposed to prevent the material leakage of the sidewall belt conveyor.

Improving the quality control of sidewall conveyor belt
The design and manufacturing standard of sidewall conveyor belt not only need consider its strength of extension and fatigue, but also need consider the quality of base belt, corrugated sidewall and diaphragm and the quality of sidewall conveyor belt assemble. Through those to ensure the whole performance of sidewall conveyor belt. The two sides of the base belt are free to bear pinch roller, which is the most vulnerable to the damage. Ensuring the standard shape and uniform of corrugated sidewall, if not, the pinch roller will wear the corrugated sidewall to cause the damage for it. The diaphragm need has a centain of strength and anti-deformation performance.
The reasonable layout of diaphragm
The separatore distance of diaphragm be confirmed according to the conveyed material size and conveying capacity. The separatore distance between the diaphragm is the integer multiples of corrugated sidewall. The vetical plate of diaphragm is installed between the two corrugated sidewall, as far as possible to reduce the lap between the corrugated sidewall.
Improving the shape design of corrugated sidewall
The corrugated sidewall belt conveyor usually used the S shape corrugated sidewall. This shape of corrugated sidewall will change that cause the distance between the diaphragm and sidewall occurs obvious change during the running. In segmental arc, with the outer ring of corrugated sidewall lengthening, the gap increasing, while in the concave arc, with the outer ring of corrugated sidewall shrinking, the gap reducing, that caused the corrugated sidewall and diaphragm deformation. The deformation of these parts will have an obvious effect on the leakage of granular materials with good fluidity.
Improving the deside of pinch roller
Pinch roller is one of improtant parts of sidewall belt conveyor, it used for chang the conveying angle. However, its structure is too simple to neglect. First of all, the manufacture is very rough, the size accuracy and smooth finish of working face is bad, and low installation accuracy. When the sidewall belt conveyor running, the outer crest of the currugated sidewall will be ground through and material leaking. The free edge of the base belt is easy to be torn by abrasion, which affects the smooth operation of the corrugated sidewall belt conveyor. The solution of improving the pinch roller can be divided into improve structure, improve the manufacture accuracy and adjust the material. A reasonable pinch roller size and smooth finish that contact with corrugated sidewall are great concerned with the position accuracy and wearability of corrugated sidewall. So appropriate to improving the manufacturing accuracy can guarantee the accuracy of the equipment installation location, reduce pressure belt wheel wear and tear of conveyor belt, not only can prevent leaks the material, also can improve the service life of sidewalll belt conveyor. The adjustment material pinch roller is usually made of medium carbon steel, and its hardness is too different from that of the corrugated belt made of rubber. In operation, the pressure belt wheel is in direct contact with the corrugated belt, which is easy to wear out the corrugated sidewall belt.
