Linear vibrating screen is one of the most important screening machines in mining and coal industries. However, linear vibrating screen always happens some troubles in operation because of the influence of production conditions. There are some resolutions for common troubles for customers’ reference.
1. The fluidity of coal on screen is not good in operation, or linear vibrating screen happens swing and vibrating will effect the service life of spring. The solution for the problem is that adjust the position of eccentric wheel if blocking in head section or tail section, and add weight of eccentric wheel when blocking in middle section.
In addition, the improper position of wash pipe used for classification or dehydration will cause the coal blocking on screen. In that case, adjust the position of wash pipe properly to bring materials up to speed. However, the method is suitable for materials in 0-3mm only.
2. The bearing blocks of linear vibrating screen are easy to shatter, and the bearings easy to heat damage while bottom beam easy to fracture caused by too heavy weight increases the exciting force and amplitude of screen. Solve the said problem can by reducing the weight of eccentric wheel, replacing springs with higher stiffness, replacing different type bearing, or changing the strength of spring. Meanwhile, strengthening the bottom beam can also extend machines’ service life.
3. The amplitude of linear vibrating screen may be lower than the parameter designed caused by various factors. Lower amplitude may reduce processing capacity of screen, and higher amplitude would reduce the service life of bearing blocks, bearings and bottom beam. In general, changing the wight of eccentric wheel or selecting springs with different strength according to specific situation can adjust amplitude of the machine to meet the need of the production.
