1. Vibrator maintenance process

Take photos and archive the original condition of the machine after entering the factory → Shot blasting → Spray primer → Disassemble the vibrator → Take photos and archive the parts → Clean the parts → Inspect, test and archive → Issue a test report → The salesperson will confirm the damage with the user Form a damage determination confirmation form → formulate a maintenance plan → receive parts → inspect, record and archive → ultrasonic cleaning → assembly → test and record and file → spray paint → ship

2. Vibrator maintenance requirements

  • Bearings

It must be replaced during maintenance, and high-quality SKF special bearings for vibrating screens must be selected to ensure that they can withstand high-intensity vibration working environments and maintain long-term stable operation. Careful installation and adjustment work is also essential to ensure the correct installation position and normal working condition of the bearings.

  • Sealing

The replacement of seals is an important guarantee for the normal operation of the exciter. When replacing, it is necessary to select high-quality seals that match the original parts to ensure that they can effectively prevent the leakage of lubricating oil or other substances, thereby protecting the internal parts of the exciter from damage.

  • Box

Boxes that are cracked, deformed, thread damaged or worn must be replaced; when the box hole and the bearing outer ring installation position are worn and the bearing does not meet the assembly requirements, they must be replaced. The new box should be replaced with high-strength ductile iron QT400-12 material, which has no defects such as slag inclusions, pores, cracks, etc. and has been inspected by ultrasonic to ensure its durability and stability. During the processing of the cabinet, the precision machining process of the CNC machining center should be strictly implemented to ensure the accuracy and stability of the cabinet.

How does an impact crusher work?

/in /by

An impact crusher is a machine used for breaking down large rocks into smaller pieces by impacting them with the force of certain wear parts.The working principle of an impact crusher revolves around the rotor, which is a heavy-duty steel drum fitted with beaters that rotate at high speeds. The material is fed into the chamber from above and is impacted by the rotor’s centrifugal force as it rotates.

Impact crusher working principle

impact crusher

Feed Material Entry: The feed material is introduced into the crushing chamber from above, typically through a feed chute or hopper. The material may be fed directly into the center of the rotor or distributed across the width of the rotor.

Rotor and Beaters: The rotor is the central component of the impact crusher and is typically mounted horizontally. It is equipped with a series of beaters or hammers that are attached to the rotor’s circumference. These beaters are free to swing or pivot on the rotor shaft.

Impact Crushing: As the rotor rotates at high speeds, the centrifugal force generated by the rotation causes the beaters to swing outward and impact the incoming feed material. This impact crushes the material against the stationary anvils or breaker plates located within the crushing chamber.

Crushing Chamber: The crushing chamber is the area where the impact takes place. It is typically lined with durable materials such as manganese steel or high-chrome iron to withstand the high impact forces generated during crushing.
