Mixing An Electrifying Seal Solution for the Cathode Powder Industry

Mixing An Electrifying Seal Solution for the Cathode Powder Industry

For the moment, at least, it looks like the future of batteries for electric vehicles belongs to the cathode powder industry. Innovations in this area are moving toward solid-state powder-composite batteries with much thicker electrode structures and, therefore, much higher capacity. The upshot: electric vehicles with far greater range.

Preparing for Growing Powder Demand

The need for cathode powder will most likely grow rapidly, and powder manufacturers need to be ready to meet the demand. So what could stand in the way?

One answer to this question is probably not top of mind, but it should be: mixer failures resulting from seal failure. Why? Because mixers and blenders failures create:

  • Potential hazards to employees
    • Potential hazards to the environment
    • High costs in time and money
    • Failure to keep up with demand and, therefore, loss of business

The time to evaluate and upgrade mixer seals is now before the demand increases. Installing CinchSeal rotary shaft seals helps ensure that mixers and blenders continue operating at peak efficiency.

High pressure rotary shaft seals

Why CinchSeal Rotary Shaft Seals?

In chemical plants, mixer and blender seal failures happen for several reasons, but the main causes include:

  • I.D./O.D. rubbing
    • O-ring failure
    • Bearing failure

I.D./O.D. rubbing

Here the issue is friction between the rotary seal member and, most often, the stuffing box bore. Eventually, the wear and tear cause leakage and failure.

O-ring failure

O-ring failure is usually the result of caustic steam cleaning. This problem has been addressed by upgrading to O-rings that can better withstand the harsh environment.

Bearing failure

This happens when contaminants infiltrate the mixers bearing housing. The problem has been addressed by upgrading the seals when the bearings are changed

These problems are inherent in sealing methods such as packing seals, lip seals, mechanical face seals, O-rings and others that have been considered sealing solutions for some time. They’re still in wide use, but CinchSeal rotary shaft seals offer a better answer.

Split rotary shaft seals

The CinchSeal solution

CinchSeal high-pressure rotary shaft seals effectively solve the three leading causes of pump failure. They also significantly reduce the maintenance time and costs.

Here are the three causes again, in reverse order, and how CinchSeal rotary seals address them:

Contaminants in the bearing housing

Two features of every CinchSeal rotary shaft seal help stop leakage and contamination:

  • Larger shaft/seal interface surface
  • Polished stainless steel-plated and PTFE rotor cups

O-ring failure

Instead of O-rings, CinchSeal shaft seals offer:

  • An air barrier created by purging that prevents the product from entering the seal
  • Cooling of the rotating seal faces to reduce friction-generated heat and prolong the useful life of the seal

I.D./O.D rubbing

CinchSeal rotary seals all but eliminates damage from rubbing. An elastomer that spins with the shaft prevents friction.

Less Maintenance, Fewer Replacements

CinchSeal high-pressure rotary shaft seals last longer. They need less maintenance, which means time and cost savings. And they don’t have to be replaced as often. But even when replacement is necessary, they save time and money. Changing them out is a simple process, so the expertise needed for other seals isn’t necessary.

This simplicity is especially evident in CinchSeal split rotary shaft seals made for harsh environments, like those found in chemical plants. Split seals offer a number of advantages:

  • Stainless steel that stands up to caustic washdowns
  • Split rotary shaft seals make conversion and installation easy
  • Easy disassembly to make batch and frequent cleanings a breeze

The Seal choice is a Cinch

To sum up, here’s why CinchSeal rotary shaft seals make the most sense of producers of cathode powder:

  • They solve three main causes of mixer and blender failures: bearing housing contamination, O-ring failure and I.D./O.D. rubbing.
  • They require maintenance and replacement less often, and, in both cases, the process is much simpler.
  • They offer an economically superior solution to failures that can cause harm to people and the environment as well the bottom line.

Since 1994, CinchSeal has been a major manufacturer of rotary shaft seals for screw conveyors, ribbon blenders and all kinds of bulk handling equipment. CinchSeal products serve as replacements and upgrades that make the need for machine replacement less likely.
