The reason and solution of the screw conveyor in the mixing plant

Screw conveyor is the core component of concrete mixing plant transportation system,extremely widely.In the actual operation process,Screw conveyor may stop working for some reason,The following is the analysis of the causes of its failure,and propose solutions.

Spiral shaft stop rotating

Reason:

1.Conveying material is too much, leading to its in the middle of the suspension shaft to bear greater resistance,increase the load of the motor eventually lead to downtime.

2.The middle bearing seal is damaged, is too large resistance, material into the bearing after the damage.

3.Material with large particle size in the process of transportation, increase the running resistance between the material and the machine groove,increase motor operating load, motor overheating open automatic protection.

Solution:

1.Strictly control the delivery of materials, to avoid overloading the conveyor.

2.Carry out regular maintenance of the middle bearing of screw conveyor,periodical replacement.

3.Strictly control the quality of raw materials, avoid large grain size materials or foreign matter into the conveyor,operation of equipment abnormal fever, noise, timely inspection, clean foreign body, dressing or spiral chute.

Spiral blade damage

Reason:

Foreign matter in raw materials can cause spiral blade damage,the blade and shaft sealing off,formation of blade tear.

Solution:

1.In the spare parts production to ensure the consistency of the blade, the welding dense and reliable, avoid slag, porosity and other defects, ensure the quality of welding.At the same time, improve the strength of the spiral shaft and drive shaft.

2.Regular inspection of the quality of the helical blade,spiral blade wear, spiral shaft deformation, reduce the intensity of the timely replacement and analysis of reasons.
