Our expertise is in bonding rubber to metal parts. For mining operations, this includes: PipeTanksChutes; & Launders. We test our materials for their ability to resist abrasion.

Compounds Tested for Abrasion Resistance:.
PC-60ARN – Proco’s proprietary Abrasion resistant Black Natural Rubber compound.
Polyurethane – 90 Durometer abrasion resistant polyurethane believed to be best.
Black Natural – 60 Durometer abrasion resistant rubber specified by our competitors.
Tan Gum – 40 Durometer rubber often specified by others because of its low cost.

Proco is a turn-key operation: we fabricate metal chutes; launders; and piping; as well as other core metal parts. We also line new parts provided by our customers, or reline old parts to extend their useable life. We fabricate, line, paint and deliver to your specifications, ready for you to install. If your equipment is too large or too difficult to transport, we can perform lining or relining at your facility.

We will be happy to provide you with a competitive quote. We will process your order promptly, efficiently and professionally.

All Testing was performed by Akron Rubber Development Laboratory, Inc. (ARDL). Tests were performed using H18 abrasive wheels and 1,000 gram load per wheel for 3,000 cycles. ASTM D 3389-05 measures the weight loss of material per revolution. Comparing just the weight loss will skew the actual results because materials have different densities (specific gravities). The information needed to fairly compare the results is volume loss. The adjustment formulas would be:

       D = S × W
       V = M ÷ D
       since W=1 then D = S
       which yields V = M ÷ S


       S = specific gravity (ratio of: material density ÷ density of water)
       W = density of water (1 g/cm³)
       D = density of material (g/cm³)
       V = total volume of material lost
       M = total mass loss of abrasion test (loss/revolution × revolutions)
