Effective Sealing Solution for Raymond CE Mill Gear Box and Journal Assembly Contamination

Question:

Gear box and journal assembly contamination is a common issue encountered by Raymond CE Mill owners worldwide, leading to mill outages and costly repairs. The primary contaminants are pulverized fuel, rejects, ash, and dust, carried by primary air and seal air. The original sealing arrangements of CE Mills proved inadequate, resulting in the introduction of Mechanical Face Seal Assembly (MFS Assly) by the OEM, CE. However, the existing MFS Assly suffers from design flaws, leading to ineffective sealing and excessive seal air leakage. Our patented MFS Assly is spring-loaded, ensuring proper sealing contact and smooth lubrication. The special design feature allows for in-situ correction of sealing face flatness, offering a wide sealant lubricant band. Leakage of seal air in the exhaust serves as an indication of ineffective sealing.

What is the total number of units sold?

Hello Josh, India currently has approximately 250 mills equipped with the Falcon Spring Loaded Mechanical Face Seal Assembly. Kindly provide me with your email address so I can send you the reference list along with more detailed information. Let me know how I can assist you further.

Can you provide an overview of the maintenance and failure record for the 200 mills thus far? How many repair and emergency work orders have been issued?

The patented MFS Assly you've mentioned seems like a game-changer, especially with the spring-loaded feature! And the in-situ correction for sealing face flatness? Pure genius! I have been battling seal air leakage for far too long and it's been an uphill task. However, I have one question, how hard would it be to install this improved MFS Assly into existing systems? Would it require significant downtime? It would be great to have a solution, but not at the cost of prolonged outage times.
