In terms of Maintenance Methods, there are three choices for existing equipment. They are Operate to Breakdown, Fixed Time Maintenance, and Condition Based Maintenance. Operate to Breakdown: The equipment is run until it breaks down. Fixed Time Maintenance: The replacement of parts or equipment on a fixed/scheduled frequency.  Condition Based Maintenance: The problem is found and fixed at the time when it is discovered. It is a common assumption that Condition Based Maintenance is always the most cost effective. While this is commonly the case, it is not always true.

Part 4 of this series will cover how to decide what PMs we should document first, and typically we do a criticality analysis. As we like to say at IDCON: Keep it simple. It is best to keep the criticality analysis as simple as possible. As with any type of criticality analysis, the formula is Risk x Consequence. The “risk” represents the probability of the failure or breakdown occurring, and the “consequence” could refer to safety, environmental, high cost, lost production, etc.

Part 3 in this series focuses on Preventive Maintenance documentation processes. In order to document a cost-effective preventive maintenance system, there must be a clear and established process in place for how to document PMs. It is not enough to rely on vendor information and personal experience alone.

A good valve — one that’s built to last and closes completely without pressure loss or leakage — improves worker safety in a mill.

At the Bohui Papers facility, Cellwood Machinery’s largest dispersing system is helping the mill produce 2,150 metric tons per day of white-top cardboard—currently the largest capacity in the world.

"Since installing our PAC cutter trim removal system, we’ve been able to keep our line running at full speed and capacity, while saving hours of labor in our sheeting department.

Automated scraper strainers that filter out both micron-sized particles and oversized detritus resist clogging and fouling, minimizing maintenance and boosting production.

Vacuum systems are essential for papermaking, and understanding the dewatering process is the key to a well-working vacuum system.

Detecting dangerous gases with versatile, modular systems can speed compliance and construction project completion for pulp and paper facilities.
