Ebbco’s Garnet Removal System is designed to continuously remove the spent abrasive that collects in the catch tank, thus eliminating downtime for clean out. The Garnet Removal or "automatic shovel" as it is commonly referred to, can be retrofitted to any abrasive waterjet cutting machine tool. The system is sized by the area (in square feet) of the catch tank, and by the high-pressure pump capabilities versus the size of the catch tank. The primary selling feature of the Ebbco Garnet Removal System is to eliminate downtime on the machine tool and maximize production. The Ebbco Abrasive Removal System comes with a choice of spent abrasive receivers, depending on the end user disposal procedures. A 55 gallon drum, self dumping hopper or bulk abrasive bag hopper give our customers different options on how to handle the spent abrasive. The last option, the bulk abrasive bag hopper, is rapidly becoming our most popular due to the ease of handling and the eliminating of the use of dumpster's and local landfills for the disposal of spent garnet. Depending on your local geographic area Ebbco can help set up a disposal / recycle program for the spent abrasive in your bulk abrasive bags. This abrasive removal / recycle / disposal program takes care of many negatives in dealing with abrasive waterjet machines:

1. The downtime and "lousy" job of shoveling out catch tanks.
2. The transfer of spent abrasive from the catch tank to the dumpster.
3. The overfilling of dumpster's and local waste haulers not being able to pick it up to dump it.
4. The breaking of dumpster's.
5. The landfill concerns due to the metal content of the spent abrasive.
6. Your closed loop system becomes your abrasive removal system sending your closed loop systems operating cost up very high.
7. Prefiltering the spent abrasive before it goes in your recycler.

Whether your company is using the Ward or Flow Abrasive Recycler the Ebbco Garnet Removal System will "Clean" the spent garnet, by removing metal pieces, wood, plastic, rubber, styrofoam, etc. These contaminates can "tax" your abrasive recycler's capabilities. Ebbco Garnet Removal System has a large suction basket with 1/8" holes to pre-filter these contaminates before depositing them into the hopper.

Many Waterjet manufacturers are supplying overflow to drain or closed loop recirculation systems to handle table overflow water as part of the machine tool package or as an option. This is due to the fact that many states and local municipalities are restricting abrasive waterjet users from overflowing the table water into the POTW (Public owned treatment works). This water contains garnet, metal particles and dissolved solids from the machining process. When the catch tank fills with garnet it displaces the water in the tank. The overflow water now has a much higher concentration of garnet and suspended solids overflowing from the table, not to mention that due to less water, the catch table water temperature will increase. If you are using an overflow to drain system or a closed loop system to filter the table overflow water, the higher concentration of solids will result in increased consumables (filters and D.I. resin) for these systems. Another important purpose for the water in the catch tank is to dissipate heat incurred from the cutting process. When this water is displaced with garnet, the remaining water will not dissipate heat as efficiently, which could result in extreme water temperatures, resulting in thermal distortion of the part that is being cut. As waterjet systems continue to increase their capabilities, such as multi-axis cutting and closer tolerance’s being held, the need for reduced thermal distortion by controlling the catch tank temperature will increase.  

The Garnet Removal System is a necessary evil, however, with most shops a reasonable system payback is easily obtained, especially when eliminating local waste haulers and local landfills. If any of these concerns apply to your company, please call the Waterjet Filtration department at Ebbco Inc. at (586) 716-5151.

 We are pleased to announce an Abrasive Removal /Recycling Program that will lower your company's operating costs and eliminate some of the concerns that come with handling Spent Abrasive.

1. The downtime and lousy job of cleaning out your machines catch tank.
2. The disposal costs of having a local waste hauler take away the Spent Abrasive.
3. The landfill concerns regarding the contents of your Spent Abrasive.
4. The high freight costs of your virgin abrasive purchases.

Ebbco Inc. is a filtration company that makes abrasive removal systems as well as other waterjet filtration systems. Ebbco's Garnet Removal System or "Automatic Shovel"" will suck the Spent Abrasive (metal pieces, wood, plastics Styrofoam, etc.) through a suction strainer (removing the metal pieces, wood, plastics Styrofoam, etc.) and pump it into a centrifugal separator. This separator drops the spent abrasive into the bulk Bag Hopper. Once the bag is full, pull it out and install an empty one. These bags should be stored until you have collected 10 - 20 bulk bags. At that time call to schedule pickup for your spent abrasive as well as delivery on your virgin abrasive. A TCLP testing report must be provided. (See attached sheets)

North Country Minerals is looking forward to helping your company reduce its operating costs and rid you of some of the Abrasive Waterjet "Headaches". Please call us to discuss your disposal situation, geographic location and virgin abrasive requirements, so you can start saving money now.
