Press for the pharmaceutical industry STOKES 550

for tabletscompactsingle-sided

The Stokes Model 550 presses are a line of 12-ton single-sided rotary presses designed for compacting a wide range of shapes required by the pharmaceutical, powder-metal and ceramic industries. Simplified adjustments, through conveniently positioned handwheel controls, allow adjustments of weight and thickness during operation in order to optimize compact quality. The press closed grid feeders feature a series of pins mounted at the bottom of the frame, which encounter materials as they feed through causing a cascading effect that drives materials into the die cavities. Adjustable gate controls at the rear of the frames permit a consistent material flow rate through the feed stations. Transit-level feed supports facilitate front-to-back and side-to-side positioning of the feed frame. Two piece precision-machined rotary heads provide accurate tool alignment and guidance that extend tool life. A lower punch leveling system compensates for tool wear and allows use of reworked lower punches. Feed hoppers, fabricated from stainless steel and arranged with vertical adjustments and lock systems, provide control of material flow to the feed frames. The pneumatic pressure / tonnage indicator system permits easy and accurate adjustment of pressure while easily determining tonnage applied. This system includes an automatic motor shut down if the pre-set load is exceeded.
