Maintenance of Potash Processing Equipment

Processing potash is a procedure that requires significant financial commitments in terms of both production organization and equipment purchasing. Making your equipment and the production process more cost efficient is imperative from the business point of view.

Preparing the Equipment

Potash is a material that can be very harmful to the equipment causing massive corrosion if the equipment is not protected from corrosion. Strommashina offers a wide array of heavy-duty dryers that are well protected from the destructive corrosion effects.

Prevent Corrosion and Rust

With the amount of salts in potash, its corrosive effect is hard to underestimate. Potash negatively affects any metal and makes corrosion that much more powerful. In order to prevent corrosion, we recommend employing heavy-duty equipment made of stainless steel or similar alloys that are less prone to rusting. At the same time, additional protection may be applied with protective coatings made of polymer materials, epoxy, etc. The very construction of the equipment also may serve the anti-corrosion purposes. With all gaps and nooks sealed, there will be less places for salts and wetness to reside and cause corrosion. Make sure that all three factors are considered: materials of the construction, protective coatings, and construction specifics.

Maintaining the Process

One of the biggest priorities should be preventing accretion. The build-up can make corrosion more likely to occur and having the accretion to intimately contact the surfaces of the equipment is generally a bad idea. Make sure that the equipment is completely cleaned up before long downtimes.

Maintaining the Equipment

All equipment components and various pieces of machinery should be regularly inspected and checked upon. Without constant maintenance, the equipment quickly becomes inefficient and can malfunction. Potash processing requires a production line that consists of various machines including potash dryers, bucket elevators, conveyors, and compactors. Regular maintenance should cover all these machines and the frequency of inspections should be considered when planning maintenance operations. Proper scheduling ensures that maintenance addresses important aspects of the production line regularly and discovers potential problems before they can cause downtimes and malfunctions.

Maintaining Bucket Elevators

  • Make sure that all lubrication points are lubricated weekly. Pay close attention to components of the equipment that are subjects to constant friction (bearings).
  • Every single bucket elevator is powered by a motor. Motor, reducer, chains, sprockets, and other moving components should be inspected and maintained according to the guidelines provided by the manufacturer.
  • All important system components should be regularly inspected. Pulleys, electrical components, drive systems, and other important components need to be checked upon periodically. Make sure that bolts and nuts are tight and that the belt is always centered.
  • The buckets should be cleaned after every single production cycle in order to avoid build-up. Make sure to regularly operate the system in order to check the belt and its flexibility.

Conveyor Maintenance

  • One of the biggest problems is accretion that accumulates over the course of multiple production cycles. Regularly removing the build-up helps in preventing corrosion and unnecessary downtimes.
  • Scraper, belt tracker, idler, rolls, fittings, drive system, and other components should be regularly inspected and serviced.
  • Make sure that lubrication points are serviced regularly at the rate recommended by the manufacturer of the equipment.


  • Compactor rolls tend to wear down quicker in the middle and regular inspections can identify when repairs and/or replacements are necessary. In order to flatten the surface, make sure to equalize the edges of the rolls with the middle portions.
  • Make sure to monitor the condition of plates and force feeders since they also tend to wear down quickly.

Potash Dryers

  • Accretion causes inefficiency and corrosion that ultimately results in malfunctions. Remove build-up as often as possible.
  • Bearings, drive systems, hammers, burners, various interior elements (lifters, flights, etc.), gears, and other system components should be regularly inspected. Careful examination is required in order to discover issues in a timely manner. Constantly inspect breeching seals, trunnion wheels, and rollers.
  • Bearings, couplings, drive systems, and other constantly moving components should be not only visually inspected but lubricated as often as the manufacturer recommends.

Warning! All recommendations listed above are only advices that can help you in improving your maintenance practices. Planning and scheduling maintenance procedures should cover a much wider list of aspects and performed by qualified personnel.

In order to ensure that your equipment will last longer and that your business will not suffer from unnecessary expenses related to repairs and replacements, make sure to form an efficient maintenance routine that will address a wide spectrum of issues common for heavy-duty equipment.
