Denucci Excavating, based in Bristol, Pa., has been in the demolition and excavation business for the past 40 years. Since experiencing rapid growth over the last 12 months, Denucci has expanded its workforce and now employs 24 people. On the production side, machinery is also being updated to meet demand, as more excavated demolition materials are produced, resulting in an increase in onsite crushing and screening.

To efficiently cope with the increased demand for recycled concrete aggregate, the producer recently upgrade its crushing equipment. Its goal was to reduce energy costs and achieve better, consistent aggregate gradation.

Denucci decided to invest in the production capabilities of an Extec C12+ jaw crusher. The crusher features a new automation package, allowing for greater control and providing more efficient and productive operation.

Key features include a standard central greasing system for efficient, centralized lubrication. This makes sure the bearings are sealed against dirt and that lubricant washed away during work is replaced right away. By lubricating the bearing frequently with small amounts of grease, the C12+ Vogel automatic lubrication system eliminates over- and under-greasing and lubrication. This means less wear, less downtime, and less money spent for repairs and spare parts.

Using an over-band magnet also ensures the removal of any steel reinforcement when concrete is crushed, a timesaving feature that also allows for better maintenance and reliability.

With a new overhaul of the chassis, using compact, heavy steel and a web and flange construction, improved strength and flexibility is offered in whatever conditions the C12+ is placed. This means the machine now has more applications, reduced maintenance, and will last longer.
