Coarse material screening machine for garbage sorting equipment

The coarse material vibrating screen is mainly composed of a screen box, screen mesh, side plate motor vibrator, and vibration damping spring. The vibrator is installed on the side plate of the screen box and is driven to rotate by the side plate vibration motor through a coupling, generating centrifugal inertia force that forces the screen box to vibrate.

The coarse material vibrating screening machine is a single mass elastic system, and the side plate vibration motor is coupled through a coupling to generate high-speed rotation of the exciter.

The eccentric block of the coarse material vibrating screen machine generates a large centrifugal force, which excites the screen box to produce circular motion with a certain amplitude. The material on the screen is subjected to continuous throwing motion by the impulse transmitted by the screen box on the inclined screen surface. During the process of meeting the material with the screen surface, particles smaller than the screen hole are passed through the screen, thereby achieving classification.The coarse material screening machine of the second-generation garbage sorting equipment

The coarse material screening machine includes equipment hygiene, complete, tightened, and intact connecting bolts in all parts, checking whether the exciter is intact, checking whether each spring vibrating screen is damaged, missing, or broken, checking whether the screen plate is blocked by debris and the screen surface is flat without damage or looseness, checking whether the inlet and outlet chutes are unobstructed, checking whether the crossbeam is welded, checking whether the control box, communication, and lighting are intact, whether the grounding protection is reliable, and whether the control buttons are flexible and reliable.

After starting the coarse material screening machine, stand next to the control box and monitor the equipment to start. If any abnormalities are found, stop the machine immediately. After starting normally, inspect each vibrating screen again for blockages, regularly observe the temperature and sound of the vibrating motor, and check whether the four corner amplitudes of the screen vibration are consistent. Check if the feeding and discharging of the sieve are normal and if there are any blockages.

When the coarse material screening machine is stoppedAfter the material on the sieve is discharged, the machine can be stopped. When parking, observe whether the sieve collides with other equipment when passing through the resonance point. If the following situations are found, it must be stopped immediately. When encountering situations that endanger personal safety or equipment safety, such as a large amount of debris stored in the screening area, poor feeding, widespread breakage of the screening screen, severe blockage of the screening chute, and severe swinging of the screening box, other abnormal situations may occur. The vibrating screen can only be restarted after the problem is resolved.
