The following is a description of machine features.
The concave shape enables the pot tender to place additional abrasive above the filler hole. When the machine
exhausts, the material will instantly feed into the pot. The result is less down time.
POP-UP VALVE ASSEMBLY
The hemispherical automatic pop-up valve stem allows pressurization of the machine four times faster than other
popup stems. It also eliminates backward flow through the sand valve, increasing the life of the valve as much as 50
times. Even when misaligned, the valve seats perfectly, every time.
Introduction of the large-sized 6" x 8" handhole allows two-handed servicing-of the inside of the machine. This
enables the operator to quickly remove any foreign object that may have fallen into the tank.
The cone-shaped machine bottom is designed at a steeper angle than the angle of repose of sand. This allows a
continuous and even flow of abrasive right down to the last pound. No residual matter remains to absorb moisture and
cause subsequent clogging.
