26 JULY 2018 Static crushing plants are typically chosen when a contract is expected to last a number of years or where deposits are extensive. Stationary plants have several advantages that include higher efficiency and capacity, lower production costs, and higher stockpile. In addition, because there are fewer electronics on the equipment, they are easier to maintain and more durable. Schoeman says that Sandvik’s supply ratio is currently 30% mobile and 70% static. “We find that the dust control is better on static crushers and we have a number of crushers that have endured for between 25 and 40 years.” The mobile crushing plants in the Kleemann PRO series have been developed especially for the challenging demands in the quarry. The new MOBICAT MC 120 Z PRO achieves an output of up to 650 tonnes per hour with a maximum feed size of 1100 × 700mm. The powerful jaw crusher with its long movable crusher jaw is the heart of the plant. To guarantee the best possible material flow, the Continuous Feed System (CFS) adapts the conveying speed to the fill level of the crusher. The CFS is active in both plants with a line coupling with the MOBICONE MCO 11 PRO so that both crushers are optimally utilised. The PRO crushing plants are equipped with an economical and powerful diesel-electric drive, and the crusher and conveyor belts are operated electrically.
