Kleemann has introduced the new Mobicat MC 120 Zi Pro, a jaw crusher plant designed for challenging quarrying operations.
The new Pro Series jaw crusher made its debut at Wirtgen’s ConExpo booth in Las Vegas.
“The Pro Series is really focused towards quarries — heavy duty applications,” said Thomas Jordan, technical sales manager for Kleemann.
“When we’re building and designing a machine for the contractor (Evo) range, we have to take weights into consideration, and heights and lengths. “On the Pro Series, we’re not constrained. The Pro Series customer isn’t worried about moving these machines around four or five times a day.”
With an output of up to 717 tons per hour, the Mobicat MC 120 Zi Pro delivers in natural rock applications.
The powerful jaw crusher has a feed opening of 122 cm x 81 cm and is equipped with an extra-long articulated crusher jaw.

To ensure the best possible material flow, the continuous feed system (CFS) adapts the conveying speed to the fill level of the crusher. On most jaw crushing systems, the operator has the time-consuming task of clearing the crushing chamber in the event of material blockages. However, this is not so with the optional crusher unblocking system.
Should material bridging occur in the jaw crusher, the crusher can be reversed with the aid of the electric crusher drive and in this way the blockage can be cleared in no time.
The crusher is powered by a diesel electric power supply.
“The whole concept is we have a diesel engine, and then a generator on board,” Jordan said. “That generator powers all of our components. Our feeder, our prescreen, even the crusher and the belt are electric drive. That’s great for fuel and great for production.”
The machines in the Pro line can be operated with the simple Spective control system via a 30-cm touch panel. All components and functions can be controlled conveniently from the ground.
The Mobicat MC 120 Zi Pro jaw crusher plant was one of four innovations from Kleemann on display at the ConExpo stand of the Wirtgen Group.
The mobile Mobicone MCO 11i Pro cone crusher was also displayed. The MCO 11i Pro is the ideal secondary crushing plant of the MC 120 Zi Pro.
Harmonized in size and performance, the MCO 11i PRO has a maximum output of 518 tons per hour. Also, part of the Pro line, the crusher is built without compromise in the same sturdy manner and designed for permanent quarrying operation.
Kleemann also displayed its Mobirex MR 130 Zi EVO2 impact crusher.
The mobile impact crushers of the EVO2 series are designed so that they can be transported easily and made ready for operation in a short time span. As well, the direct diesel drive concept ensures a high output while simultaneously keeping consumption low. For better capacity utilization and productivity, the system widths of the impact crusher plant open in the direction of material flow. The plant is also operated using the intuitive Spective control concept.
The overall system delivers an output of up to 496 tons per hour.
The ideal support unit for all three crushing systems is the new double-decker Mobiscreen MS 952i EVO classifying screen, which made its North American debut at ConExpo.
Like the Mobirex MR 130 Zi EVO2 impact crusher, the screening plant of the Evo line can be deployed flexibly thanks to ideal transport dimensions and short setup times.
These advantages make it a viable choice for crushing plant contractors, not only in recycling but also quarrying.
The MS 952i EVO has a screening surface of 1.5 metres by 6 metres and boasts an output of up to 550 tons per hour. The high output is largely attributable to the good material flow through the plant. This starts with loading, which can be carried out both by wheel loader and upstream crushing plant thanks to the generous feed hopper.
A speed sensor on the belt is another advantage. If this machine senses it’s getting too much material, it sends a signal back to the feeder to slow down.
“When it clears itself, it sends a signal back to speed up. It’s constantly monitoring itself,” Jordan said.
“When we deliver these, I like to tell operators ‘you have one job’ just to keep material in the feeder and this machine will look after itself.”
The material is also transported on an extra wide feeding conveyor of 1.2 metres to the screen casing.
“A screen is a screen, but we sat down and said how can we improve the process? How can we be more efficient?” Jordan said. “Widening that main belt is one. It sounds simple, but it’s really effective.”
