Anti Thermal Breakdown Rubber (ATB) is a soft natural rubber based on R26, but with improved thermal conductivity. It is intended for use as a liner material in slurry pumping applications where high impeller peripheral speeds are required. R26 is a black, soft natural rubber. chinatown restaurant banawe

"WitrynaThe reference value for the jet velocity was the peripheral speed of the grinding wheel (v jet ≈ v s = 35 m/s). They kept all other process parameters constant. They found that the process capacity (the grinding burn limit) depends directly on the jet velocity. " - Impeller peripheral speed
