Housing System

The Tertiary Crusher Housing is a rugged, fabricated steel plate construction with external bracing (ribbing) for increased strength. For quick and easy inspection of the internal parts, the housing is fitted with very large doors that swing open to permit full side access for parts inspection and maintenance. With simplicity and function in mind, the housing is fitted with thick, interchangeable, wear-resistant liners that have been designed as a common shape. The housing system is stress relieved to increase its service life and to provide workmanship of the highest quality.

Liner System

With simplicity and function in mind, the housing is fitted with 1 inch thick, interchangeable, cast wear-resistant liners that have been designed as a common shape. The liners have an interchangeability level of approximately 95%. A further benefit with this liner design is realized in the form of increased wear metal utilization. A worn liner, for example, can be repositioned from a high wear zone (within the rotor circle), to a low wear zone (outside the rotor circle), thus extending its service life. The standardized design of the housing liner system helps to further reduce the impactor cost of operation.

Aprons

The impact aprons (right / left) are a heavy-duty fabricated component equipped with thick, replaceable bolt-on impact plates of high quality, wear-resistant cast alloy. The aprons are identical (base frame / impact liners) which helps to reduce inventory costs along with lowering the impactor cost of operation. With function and simplicity in mind, adjustment of the impact aprons is achieved by a hydraulic cylinder / control panel. Reaching the desired gap setting only takes a few minutes and no tools are required.

Third Crushing Path (Patented Design)

The crushing path is designed as a series of impact steps (or ledges) which provide an excellent level of control over the product grading, enhanced product soundness and very high cubical product shape. The crushing path can be adjusted (top & bottom settings) through external hydraulic cylinders.

VR2 Rotor

The VR2 Rotor is offered for the production of manufactured sand. In this system, the blowbars are secured into position by a single piece locking brace system. This design permits the removal of the blowbars in the side direction. The blowbars, which can be rotated 1 time, have a metal utilization rate of approximately 50%. Exchange time, varying with the machine size, takes approximately 20 minutes per row. The rugged design of the VR Rotor system, combined with its operational flexibility permitting the installation of various thickness blowbars, is an ideal choice for the tertiary processing of raw materials. A major benefit of the VR Rotor system is its symmetrical shape which permits its operation in the clockwise or counterclockwise direction.

The VR rotor offers a very high level of operational flexibility. In addition to its reversible design, the rotor system can accommodate three (3) different blowbar designs that vary in their thickness. For example, when processing 1 inch clean stone down to manufactured sand, the 40mm thick blowbar is the optimum choice. For larger feed materials, up to 3 inch, the 75mm thick blowbar (available in ceramic alloy) is utilized.

VR4 Rotor

In this system, the blowbars are secured into position by a single piece locking brace system. This design permits the removal of the blowbars in the side direction. The blowbars, which can be rotated 1 time, have a metal utilization rate of approximately 50%. Exchange time, varying with the machine size, takes approximately 30 minutes per row. The rugged design of the rotor system, combined with its operational flexibility (4 rows crushing or 2 row crushing) is an ideal choice of the tertiary processing of raw materials. A design of this rotor system also permits its operation in the clockwise direction.
