Failures and Troubleshooting of an Industrial Centrifuge

An industrial centrifuge is generally used to extract and filter cannabis and other plants. It can extract the active ingredients in plants through a built-in program, which is single-handed, easy to use and large in capacity. But sometimes an industrial centrifuge can not work well because of long use or improper operations. For the better use, we are supposed to have a deeper understanding of some simple failures and common troubleshooting of an industrial centrifuge.

Precautions for Using an Industrial Centrifuge

  1. Stop the centrifuge and check it immediately when it makes noise or appears some other abnormal phenomenon while it’s running. Do not adjust, maintain and troubleshoot the centrifuge under running conditions, and take necessary protective measures.
  2. When the serious corrosion happens to centrifugal drums, spindles, other rotating parts and other important parts, replacement or modification should be taken. And do not use unsafe emergency measures such as surface repair welding.Centrifuge damaged parts need to be replaced in a timely manner. Once important parts such as transmission parts, load-bearing parts and safety-related parts are found to have cracks, serious corrosion, and unsafe factors such as strength and reliability, stop operation immediately.
  3. The technical condition of the centrifuge must ensure that its main technical parameters (vibration, noise, temperature rise and other indicators) meet the relevant standards.
  4. According to the corrosiveness and use environment of the medium separated by the centrifuge, the centrifuge end-of-life cycle is formulated according to relevant regulations. If it is found that the key parts such as the drum, the main shaft, the base, the cover, and other parts are cracked or severely corroded, they should be immediately forcibly scrapped.
  5. Monitor and record the operation of the centrifuge. Describe in detail the fault conditions, causes and solutions during the operation of the centrifuge. Keep a record of handover.
  6. For the key parts of the centrifuge: the drum parts, the main shaft parts, the machine base and the casing parts must be adjusted and repaired by workers with professional technical knowledge and special skills.
  7. Daily maintenance and overhaul of the centrifuge, such as daily lubrication, bolt tightening, belt tension adjustment, filter bag replacement inspection, etc. must be carried out by professional personnel.

Failures and Troubleshooting of an Industrial Centrifuge





Abnormal shake

Drum unit

Uneven loading

Stir the extracted material to make the charge uniform

The filter cloth (bag) is damaged or not properly leaked, which makes the drum lose balance.

Re-attach the filter cloth (bag) or replace the repair

Spindle component

Severe wear or damage to the spindle bearings

Replacement bearing

Loose spindle nut

Fastening nut

Base unit

The base is not installed horizontally or the foot nut is loose.

Adjust the horizontal fastening nut

Shock absorber damage

Replace the shock absorber

Abnormal noise


Loose transmission parts

Tighten the loose parts



Seal aging

Replacement seal

Excessive feed or filter cake containing too much liquid

Filter cloth (bag)

Filter cloth (bag) is not selected properly,

Filter cloth (bag) is damaged or not fit properly

Select the appropriate filter cloth (bag) to repair and replace the filter bag according to the nature of the material.

Starting current is too large

Motor heating abnormality


Motor is defective

Repair or replace the motor

Loading exceeds rated amount

Loading by rated capacity

Parts are loose, detached or damaged

Fastening replacement parts
