Common causes of wear of spiral blade in use

There are three types of spiral blades of screw conveyor: solid spiral surface, belt spiral surface blade spiral surface. Among them, the blade spiral surface is relatively less used, mainly used for conveying materials with high viscosity compressibility. This spiral suspension surface type has the function of mixing mixing materials in the process of conveying operation.

Any product in use can withstand long-term wear, because it will greatly reduce the service life of the product, spiral blade is also the case. When using spiral blade, users need to know the reason of its wear, in order to reduce the degree of wear of spiral blade.

In the running in stage of spiral blade, because the product is relatively rough, there will be greater friction at this time. For the wear of spiral blade, the friction is very large at this stage. Users should pay special attention to this.

When the surface of the product becomes slightly smooth, the clearance between the spiral blades should be increased appropriately. Of course, we must master the principle of moderation in everything. If the clearance of propeller blade is adjusted too large, the friction between the screw blade the product will be increased, the wear of the machine will be increased. In addition, due to the high friction of spiral blade, it may lead to equipment failure. Keeping blade clearance is a bad thing. Through early friction, the product becomes smoother. If the whole machine maintains good lubrication effect, the friction effect will wear at the same time, which can greatly reduce the wear of the machine.

Although it is inevitable to wear when using the machine, the spiral blade must be worn as much as possible to prolong its service life.
