TST jaw crusher

Jaw crushers

2

FLSmidth’s history with the design and manufacture of jaw crushers dates back more than 100 years with the Traylor and Fuller-Traylor double toggle jaw crushers. These crushers have continuously withstood the harshest duties found in the world. With constant and continual improve-ments to the designs, the TDT has been solidified as a preferred crusher throughout the industry. FLSmidth is proud to add their new line of single toggle jaw crushers, the TST, to the heritage the double toggle crushers established.

The TST jaw crushers are engineered for trouble-free operation, character-ized by safe and easy serviceability. The most modern analysis techniques and features available to date ensure a strong and reliable crusher design. In order to handle the increasingly hard ores and remote locations common in the industry today, the TST is equipped with an efficient crushing motion, modular frame and a simple, low maintenance design.

Design

An often overlooked, but very important, characteristic of the single toggle jaw crusher is its kinematic design. The chamber design enables the TST to efficiently crush hard material via a combination of shaft eccentricity, toggle angle and chamber layout. While the chamber is designed with a very steep nip angle, all other connected components are designed to enable the units to easily crush the hardest rock at high production rates, while maintaining the necessary product size.

The active feed opening of the jaw crusher chamber ensures that any occasional oversize material will be gripped

and quickly pulled into the crusher. Once the jaw plates pull in the material, its steep nip angle ensures continual grip

and efficient crushing of even the hardest material.

Since a crusher is only as strong as the components that support it, FLSmidth concentrated on designing a very strong base for all other components. The design is based on a modular-type frame that is bolted and pinned, and capable of heavy duty operation. FLSmidth’s exclusive design is stronger and more robust than other traditional and modular designs.

The frame and swing jaw crushers feature double-roll spherical roller bearings to allow for any misalignment that may occur. All overloads are absorbed by the generous bearing size and safety factors that FLSmidth

utilizes in each crusher model. The bearings are supported by a large diameter forged alloy steel, generous radii and no threads to ensure that all stress risers are eliminated. Bearings are lubricated by grease and protected from dirt by a multi-pass labyrinth.

Instead of a breakable toggle plate, FLSmidth’s design utilizes a tramp relief shear pin (FLSmidth’s safety pin) which, when un-crushable material is encountered, shears and protects the crusher. The safety pin works by removing the flywheel’s kinetic energy from the crusher shaft, thus preventing overstressing the crusher.

1. Abrasion resistant cheek plates are easier to

replace

2. FLSmidth’s bolted and pinned frame assembly

comes together for a very strong and robust

design

3. Swing jaw & front frame employ replaceable

jaw plate holders in the event of wear.

4. Rolling toggle design and replaceable abrasion

resitant toggle seats provide long life

5. Hydraulic cylinder wedge adjustment takes up

wear seen on the jaw plates

6. Safety shear pin provides faster and safer

maintenance than a typical breakable toggle

plate

7. Spherical roller bearings use a multi-pass

labyrinth and grease to minimize dust and dirt

ingress.
