How do I dispose of spent garnet?

Prior to disposing of spent garnet, please review applicable local, state and federal regulations. Although BARTON abrasives are classified as non-hazardous, it is the responsibility of the waste generator to ensure spent materials are disposed in accordance with applicable solid waste regulations. Depending on the waste generation process, additional testing (i.e. Toxicity Characteristic Leaching Procedure (TCLP)) may be required in order accurately assess the proper waste classification.

What is the shelf life of garnet abrasives? Is there an expiration date?

BARTON garnet abrasives are naturally occurring minerals that do not contain chemical additives. There are no product expiration dates. However, proper storage methods need to be followed. Store abrasives in a cool dry place; preferably indoors. Keep container/package tightly closed and in a well-ventilated place without large temperature swings to prevent condensation. Abrasives stored in FIBC’s - flexible intermediate bulk containers, commonly called bulk bags, must be kept out of direct sunlight as UV light can deteriorate FIBC’s that are intended to be single use bags.

What are the advantages of using an abrasive bulk hopper and bulk bags?

Bulk bags provide the advantage of loading the abrasive hopper in one shot as compared to 55 LBS at a time with paper bags. The risk of paper bag contamination is also eliminated. Proper handling of bulk bags may also reduce the possibility of injuries related to handling paper bags. FIBC guidelines must be followed when handling bulk bags, and the bulk hopper must be installed properly. Installation guidelines for the BARTON abrasive hopper.

Should I pre-screen my abrasive? Why?

Our manufacturing processes are built on strict, comprehensive quality control standards to ensure the proper particle size distribution (PSD) and abrasive quality. However, when opening paper bags, fibers or contaminants could be introduced into the abrasive. Therefore, we recommend screening the garnet to help capture these particles.
