KPI-JCI and Astec Mobile Screens expanded its Vanguard product line with the more compact 2056 Vanguard jaw crusher, which features a 20-in. x 56-in. jaw crusher that is ideal for sand and gravel applications. According to the company, the 2056 Vanguard also excels 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-16 in.,” 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 ton over the lifetime of the crusher.”
Significant changes engineered into the new 2056 model are a new single cylinder auto-tension system, which offers less maintenance, increased reliability and reduced wear part consumption, the company says. 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 unique 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, adds KPI-JCI and Astec Mobile Screens. 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 1 1/4-in. stroke and heavy-duty flywheels result in a lower fuel cost per ton, the company says.
