Leak-Free Rotary Shaft Seals Essential for Mixing Lithium Ion Battery Slurries, Pastes, Gels and Powders
Rotary shaft seals for battery slurry mixing equipment play a critical role in lithium-ion battery production. Leaks past the radial shaft seal can be costly and dangerous. Rotary shaft seals from CinchSeal are uniquely suited to eliminate leaks. The result is reduced maintenance, elimination of shaft wear, reduced downtime, and the lowest total cost of operation for cathode and anode slurry mixing operations for lithium-ion battery producers.
The future of batteries for electric vehicles looks to belong 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.
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.
Why CinchSeal Rotary Shaft Seals?
In chemical plants, mixer and blender failures happen for several reasons, but the main causes include:
Premature bearing failure
Irreversible damage to shafts
Expensive battery powder leakage
Toxic environment contamination
Premature Bearing Failure
The CinchSeal self-adjusting design does not allow contamination build-up in the bearing housing
The self-lubricating seal enables a dry-running seal operation, decreasing its wear and tear
Irreversible Damage to Shafts
CinchSeal rotary seals eliminate damage from rubbing. An elastomer that spins with the shaft prevents friction.
Moreover, it can tolerate shaft misalignment of up to ¼ inch, common in bulk-handling equipment, without losing its seal
Expensive Battery Powder Leakage
An air barrier created by purging prevents the product from entering the seal
It also develops a force that pushes the rotating faces outward against the stationary faces and creates a tighter seal
Cooling off rotating seal faces reduces friction-generated heat and prolongs the useful life of the seal
Toxic Environment Contamination
Two features of every CinchSeal rotary shaft seal help stop product leakage and environment contamination:
Larger shaft/seal interface surface
FDA-approved silicon elastomer and PTFE rotor cups
Less Maintenance, Fewer Replacements
CinchSeal 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. When it is necessary, only internal parts – elastomer and rotor cups – need to be replaced. Changing them out is also a simple process.
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 harsh working conditions
Split rotary shaft seals that make conversion and installation easy
Easy disassembly to make batch and frequent cleanings a breeze
