In the process of organic fertilizer production line, drum screener machine and vibration screener machine are common screening equipment, mainly used to separate qualified particles from unqualified materials. However, fertilizer screener machines may get clogged during operation, affecting production efficiency and product quality. To address the clogging issue, it is necessary to analyze the causes and take corresponding measures to ensure the normal operation of the equipment.
1. Causes and solutions for drum screen clogging
drum screener machine rely on the rotation of the drum to make the material slide and pass through the sieve holes for screening. However, in some cases, the material may get stuck in the sieve mesh, causing clogging.
(1) Excessive moisture in the material
Material with high moisture content is prone to adhering to the surface of the sieve mesh, affecting the screening efficiency.
Solution: Before screening, use a drum dryer to reduce the moisture content of the material, or install cleaning devices such as brushes or rubber balls inside the drum to reduce material adhesion.
(2) Worn sieve mesh or improper mesh size
Long-term use of the sieve mesh can cause deformation of the mesh holes, affecting the screening effect.
Solution: Regularly check the wear of the sieve mesh and replace it with a suitable size in a timely manner.
(3) Excessive feed rate
Excessive feeding can cause material accumulation, leading to poor screening.
Solution: Control the feeding speed to ensure that the material enters the drum screen evenly. A screw conveyor can be used to adjust the feeding rate.
2. Causes and solutions for vibrating screen clogging
vibration screener machine rely on vibration to push the material through the sieve mesh. However, if the equipment or material condition is poor, clogging can also occur.
(1) Sieve mesh clogging
Fine particles can easily get stuck in the sieve holes, reducing the screening effect.
Solution: Choose a sieve mesh with an appropriate hole size and clean it regularly. Use bouncing balls or ultrasonic cleaning devices to reduce clogging.
(2) Insufficient vibration force
Insufficient vibration force can cause the material to remain on the surface of the sieve mesh, affecting the screening efficiency.
Solution: Check if the vibration motor is operating normally and adjust the vibration force or the inclination angle of the sieve surface as needed.
(3) Uneven material distribution
Concentration of material in a certain area of the sieve mesh can lead to local clogging.
Solution: Adjust the feeding device to ensure even distribution of the material on the sieve surface and improve screening efficiency.
