What Is the Difference Between a Tramp Oil Separator and a Coolant Recycling System?

Published August 13, 2026. Last updated August 13, 2026. Quick Answer A tramp oil separator is a single-purpose device that removes floating or dispersed hydraulic oil and lubricants from coolant. A coolant recycling system is a complete, multi-stage plant that performs oil removal, then adds particulate filtration, concentration control, and bacteria control so the coolant can be pumped back into […]

How Much Can a Coolant Recycling System Save My Manufacturing Facility?

Published July 20, 2026. Last updated July 20, 2026. Quick Answer: A coolant recycling system typically reduces new coolant purchases by 50 to 75 percent and cuts coolant disposal costs by up to 90 percent, while recovering 95 to 98 percent of metalworking coolant for reuse. Most manufacturers see full return on investment within 6 to 18 months, with high-volume […]

How Do Chip Wringers Affect Coolant Concentration and Quality Upon Recovery?

Written by Paul Montgomery, Marketing Leader, PRAB, Inc. Reviewed by Mike Proos   |   Published July 2, 2026   |   Last updated July 2, 2026 Quick Answer: A wringer uses centrifugal force to fling cutting fluid off metal chips, recovering fluid that would otherwise leave with the scrap. The recovered fluid is mechanically separated, not chemically cleaned, so it can carry fines […]

How to Choose a Metal Chip Processing System – The PRAB Framework

PRAB’s Metal Chip Processing Selection Framework is a structured decision tool for metalworking operations selecting between wringers, briquetters, crushers, and centrifuges. The framework aligns three operational variables, scrap volume, metal type, and fluid content, with the equipment configurations that consistently deliver up to 90% scrap volume reduction, up to 98% coolant recovery, and up to 25% increase in scrap resale […]

What Is the Best System for Aluminum Chip Recycling?

Aluminum chip recycling is one of the most effective ways manufacturers can recover value from machining operations. For companies machining aluminum, chips and turnings are not just waste—they are a reusable asset. Yet many facilities still lose profit by hauling wet chips, storing bulky swarf, paying excessive freight, or allowing reusable coolant to leave with the scrap. The best aluminum […]

Copper at $5/lb and Rising – How to Turn Your Machining Scrap Into a Significant Revenue Stream

There’s a calculation most manufacturing operations never run. It goes like this: take the machining scrap pounds of copper, brass, or bronze chips your facility generates per week, multiply by the current scrap price ($3.40–$5.10/lb depending on grade and cleanliness), subtract the discount your scrap dealer applies for oil contamination and loose bulk, and compare that to what you’d earn […]

The Other Metal Crisis- Why Copper Prices Are Rewriting the Rules for Manufacturers

Aluminum has dominated the commodity headlines this spring — but copper prices have been quietly building a more consequential story. While aluminum’s challenge is supply: mines capped, smelters disrupted, capacity maxed — copper’s challenge is something fundamentally different. It’s demand. Demand that no amount of new mine construction can keep up with, demand from industries that didn’t even exist a […]

From Scrap to Profit – Why FREE Materials Testing Protects Metal Chip Processing ROI

Metal Chip Processing Is Now a Profit Center Metal chip processing directly affects: Metal Scrap resale value Coolant recovery and reuse Haul-away and storage cost Floor space utilization Yet many systems are still selected without application-specific data. Why Generic Performance Data Fails Chip Geometry and Coolant Chemistry Matter Two aluminum (or any metal) plants rarely produce the same chips. Differences […]

PRAB Systems Aren’t Just for Large Plants -How Smaller and Mid-Size Manufacturers Benefit from Modular Scrap and Coolant Recycling

When manufacturers research metal scrap handling, coolant recycling, or industrial water reuse systems, PRAB is often the benchmark for large, complex operations. That reputation is well earned. PRAB systems are widely used in centralized coolant management, plant-wide conveyor networks, ISO 14001 environmental compliance, and closed-loop water reuse—challenges typically associated with high-volume production environments. But that perception has created a misconception. […]

Why “High Cost” and “Downtime Risk” Are the Wrong Lens for Metal Chip Processing

How PRAB Reframes Capital Investment as a Fast-Return, Low-Disruption Strategy: Metal Chip Processing Solutions Across manufacturing, metal chip processing systems are increasingly recognized as essential to operational efficiency, safety, and sustainability. Yet two objections still dominate: high initial cost and integration downtime. These concerns are understandable—but they are also increasingly misaligned with how modern metal chip processing projects are actually […]
