What to reviewReview the collector duty, filter media, cleaning performance, and replacement-element requirements.
Filter leaks are difficult to detect

Combustible dust affects equipment selection
What you may noticeDust characteristics introduce additional requirements for collection, transfer, and process equipment.
What to reviewCoordinate equipment selection with the facility’s dust hazard review and qualified protection specialists; collection alone does not address every hazard.

What you may noticeMaterial arrives too slowly, or a new route must fit limited floor space and headroom.
What to reviewCompare conveying methods around capacity, distance, elevation, access, and material properties.

What to reviewReview the complete path: material feed, air supply, piping, receiver filtration, and discharge.
Abrasive material wears through equipment
What you may noticeElbows, valves, and other contact points need frequent repair or replacement.
What to reviewIdentify where wear occurs and evaluate component design, materials of construction, and operating conditions.
Rotary valve wear, jamming or leakage
What you may noticeA rotary airlock becomes a maintenance bottleneck or no longer performs as required.

Valve leakage, powder escape & incomplete shutoff
What you may noticePowder escapes around a slide gate, material passes a closed valve, or an isolation point loses pressure or vacuum.
What to reviewReview Britton cast-body slide valves and application-specific seals for improved containment. Confirm the required shutoff, pressure differential and material; inflatable-seal options are available for appropriate duties.
Storage, Monitoring & Packaging
Connect inventory visibility, filling, and production planning.

Material flow is difficult to confirm
What you may noticeA conveyor runs without delivering material, or the actual solids rate is unclear.
What to reviewSeparate the need to detect flow/no-flow from the need to measure mass flow, then select the appropriate instrument.
Slow, dusty or inconsistent bulk bag filling
What you may noticeBags take too long to fill, weights vary, or product spills during filling and removal.
What to reviewCoordinate the feed device, weighing, bag connection, dust control, and filled-bag handling.
Empty bags take up too much space
What you may noticeDiscarded bags accumulate around the line and require repeated handling.
What to reviewEvaluate compaction and collection arrangements around bag type, waste volume, and the available work area.
Pallet handling & load protection need improvement
What you may noticeManual wrapping or strapping slows dispatch, or loads are poorly secured for handling.
What to reviewReview end-of-line packaging and pallet movement around load format, throughput, and shipment requirements.
A plant upgrade needs several connected solutions
What you may noticeMultiple suppliers, equipment interfaces, or an uncertain scope make expansion difficult to plan.

Questions About Choosing a Solution
Can one material handling problem have several causes?
Yes. Poor discharge, for example, can involve material behavior, hopper geometry, outlet size, or the equipment below the hopper. Reviewing the process helps narrow the cause before selecting equipment.
What is the difference between magnetic separation and metal detection?
Magnetic separation removes magnetically susceptible contaminants. Metal detection can identify ferrous, non-ferrous, and stainless steel contaminants, subject to the application and detection limits. The appropriate approach depends on the material, contaminant, and inspection location.
Should I use a screener, a filter, or a liquid-solid separator?
The choice depends on the separation task. Screening can remove oversize particles or separate size fractions. Liquid filters address unwanted particles in liquid streams. Liquid-solid separators are evaluated for solids recovery or dewatering. The material and separation target determine the suitable equipment.
Can you help improve an existing line?
Yes. Share the existing equipment, the symptom you want to address, and the available space. CMT can help evaluate individual equipment changes or a coordinated system approach with the relevant suppliers.
