Common faults and corresponding solutions of drum screen

　　Drum screen is a specialized screening equipment developed for industries such as building materials, metallurgy, chemical engineering, and mining. It overcomes the blockage problem of circular vibrating screens and linear vibrating screens when screening wet materials, improves the output and reliability of screening systems, and is widely used in sand and gravel separation in sand and gravel fields, as well as in size grading and block powder separation in chemical and mineral processing industries. It is highly favored by customers.

　　Drum screen is a relatively large processing equipment in screening equipment. Although it does not have the complex structure of magnetic separators, sorting machines, etc., it has a large processing capacity during use. Therefore, some mechanical failures are inevitable during long-term use. The following are several important and easy to occur failures, and corresponding solutions are provided. We hope it can help you.

　　1. Noise problem caused by loose equipment bolts

　　Solution: Re tighten the bolts or other fasteners;

　　2. Wrong rotation direction caused by incorrect connection of motor power cable

　　Solution: Replace the power cable in the junction box;

　　3. Delayed clicking start caused by motor overload or excessive conveying capacity

　　Solution: Adjust the conveying capacity again;

　　4. Insufficient ventilation or lack of lubricant inside the gearbox leads to overheating issues

　　Solution: Check and adjust the ventilation vent for heat dissipation and add lubricant;

　　5. Electric motor heating problem

　　resolvent:

　　(1) Clean the heat sink of the electric motor;

　　(2) Check if the fan impeller is working properly and ensure smooth air circulation;

　　(3) Reduce load;

　　(4) Tighten the connection;

　　(5) Check and rewire.

　　6. Blocked sieve holes prevent the drum screen from functioning properly

　　Solution: Clean up the clogged garbage in the sieve holes in a timely manner to reduce blockage.
