Stokes Model 516

Heavy-duty Rotary Press - Double Sided

Compacting Press

The Stokes Model 516 is a heavy-duty 15 Ton rotary press designed for double-sided operation. The press can handle up to 2 1/4'' fill and 3 1/2'' compact sizes. Optional 20 ton force is available.

Construction Features

Mainframe and crosshead are sturdy machined castings and cams. Pressure rolls are hardened steel for superior tool and part life. The two piece head is precision machined to ensure accurate tool alignment and guarantee the die table is precision ground and polished.

Pin Type Transit Level Feeder

The feeder funnels material directly over the die cavity. Stationary pins cause a cascading action that improves filling of the dies for accurate tablet weights. An adjustable gate also maintains fluidity tunnel of granulation and prevents packing in the frame.

Three Point Transit Leveling

Arrangement permits simple and precise setup of feed frame. No resetting of feeder is required.

Stainless Steel Hopper

Vertical adjustment and lock provision.

Dust Removal Suction Nozzles

Positioned above and below the die table for clean operation.

At ejection, allows for the use of reworked tooling.

Adjustable Upper Roll

This feature permits compacting of tablets at various points in the die, which extends die life. It also minimizes capping and laminating of tablets.

Handwheel Control

Press speed, fill and pressure settings.

Keywayed Upper Punch Sockets

These sockets provide punch alignment when producing tablets of irregular shape are standard.
