American crushing and screening sector heavyweight KPI-JCI and Astec Mobile Screens has expanded its Vanguard product line with the new, more compact 2056 Vanguard Jaw Crusher.

The 2056 is a 508mm x 1,422mm jaw crusher said to be ideal for sand and gravel applications. The model is also said to excel in recycled concrete and mining applications.

“The small gap provides an excellent nip angle at a tight closed-side-setting, making this the perfect jaw for applications where the material is minus 16mm,” says Ron Griess, product manager for KPI-JCI and Astec Mobile Screens. “Additionally, the crusher’s high reliability paired with best-in-class performance leads to a lower cost per tonne over the lifetime of the crusher.”

Significant changes engineered into the new 2056 model include a new single cylinder auto-tension system, which offers less maintenance, increased reliability and reduced wear part consumption. The crusher’s new wear seat provides easy access and increased uptime, while a new corrugated stationary wedge increases the crusher gap and maintains a steep nip angle, providing less slippage, lowering the wear costs by providing longer jaw die life. Its novel flywheel retention system secures the flywheel in place, providing unmatched reliability and longevity.

The innovative shaft and bearing assembly increases serviceability and reduces maintenance and rebuild cost, providing a lower total cost of ownership through the lifetime of the machine. The electric motor mount, v-belt drive and guarding are all integrated on the machine, providing an easy-to-install compact package for mobile or stationary applications. A large 31.75mm stroke and heavy-duty flywheels result in a lower fuel cost per tonne and is said to offer 33% more inertia than competitive models.
