Shaft screw conveyor can transport granules, powder and small pieces of raw materials, etc. There are various ways to transport, such as: horizontal transport, inclined transport, vertical transport, etc. The transport interval can vary from two meters to seventy meters, if the operation is wrong or do not pay attention to maintenance, it is easy to produce all kinds of common problems, material blockage is a common one. Why does material blockage occur? How to solve the blockage situation?

The cause of the common problem of material clogging is easy because the actual operation staff did not follow the operating specifications of the strict actual operation, the actual operation staff in the start to ensure that no load, feeding material to be uniform, full load should stop delivery, can not be loaded to run, in order to ensure uniform feeding can also be installed feeder. Feeding the whole process if a feed is also very easy to cause material clogging, but also continue to enhance the destruction of the screw blade, and therefore to ensure that one at a time to improve the feed, slowly to achieve the rated value of the feed working capacity.

In the selection of shaft screw conveyor, need to take into account the delivery of raw materials, conveying volume, delivery speed, motor rated power and other factors, if the use of shaft screw conveyor and the raw materials to be transported and the effect achieved do not match, also very easy to make the shaft screw conveyor material blockage problems, so the use of shaft screw conveyor should be carefully considered, choose the delivery of raw materials to achieve the desired effect. Screw conveyor after transporting raw materials, machine to have the presence of slag, if not cleaned, will continue to lead to large residual slag or synthetic fiber slag caused by clogging, so in order to reduce the formation of material clogging, transporting raw materials should be cleaned inside the equipment.

Delivery roller bearing is very easy to occur material blockage problem, so in order to well reduce the formation of common problems of material blockage, should try to reduce the cross specification of the suspension roller bearing. In addition to the above methods, it can also be based on the installation of silo level and blockage magnetic induction equipment to complete the automatic control system and alarm; improve the feed opening or increase the length of the feed trough, which can scientifically solve the problem of blockage in the feed trough, and can install a small section of positive rotating blade at the top of the feed trough. It can scientifically prevent the formation of common problems of material blockage at the end.
