Used 2020 Stokes 900-513R Custom 23-Station Rotary Tablet Press – Die-Twisting Ejection, Under 2 Pressing Hours

Manufacturer Information

Stokes

Stokes is a long-established name in tablet compression equipment, with rotary tablet presses used for pharmaceutical, nutraceutical, confectionery, chemical, and specialty tablet manufacturing.

This Stokes Model 900-513R is a custom-configured rotary tablet press built around the established 900-513 platform. Its distinguishing feature is a specialized die-twisting design intended to rotate the dies to help break product sticking during tablet ejection.

Manufactured in 2020, this machine is reported to have less than two hours of actual tablet-pressing operation.

Description

Available for sale is a used 2020 Stokes Custom Rotary Tablet Press, Model 900-513R, Serial Number 032036, equipped with a 23-station rotary turret and a specialized die-twisting ejection arrangement.

The machine's most notable feature is its custom die-twisting design. During the tablet ejection process, the dies rotate to help break sticking between the compressed product and tooling. This configuration was developed as a specialized solution for formulations where sticking during ejection can create production challenges.

The press incorporates a 23-station rotary turret, product hopper and feed system, compression and adjustment controls, machine guarding, and floor-mounted drive assembly.

Electrical requirements are 480V, 3-phase, 60 Hz, 10 amps.

Built in 2020, the machine reportedly accumulated less than two hours of actual pressing operation, making its extremely limited reported production use a significant feature for buyers evaluating used tablet-compression equipment.

Potential applications include pharmaceuticals, nutraceuticals, vitamins, dietary supplements, confectionery products, chemicals, and specialty compressed tablets, particularly formulations where tablet sticking during ejection is a concern.

Specifications

Key Feature – Custom Die-Twisting Ejection Design
