AGGREGATES AND CIVIL CONSTRUCTION WASTE CRUSHING
A new vision One issue that has become more frequent in the past few years has been the choice between mobile or stationary crushing plants. Which one is the best choice? In a simplistic way, stationary plants are preferably chosen for
projects that will last more than 10, 20 years, whose costs with civil and infrastructure works are diluted over time. In addition, they are famous for delivering high hourly production at an acceptable cost. The mobile Kleemann crushing and screening units have been developed to break this paradigm. The crushers have a rated capacity ranging from 200 t/h and 1000 t/h, with the necessary robustness for these operations. In addition, they have the exclusive diesel-electric drive, which reduces fuel consumption providing a lower ratio R$ / ton.
Advantages of mobile crushing and screening:
From discourse to practice Kleemann has within its main technical advantages the diesel-electric drive
Mobility between sites or inside one same area Flexibility: depending on the aimed products, the disposition of equipment may be modified Fast operation start Drastic reduction or even elimination of civil works Possibility of operation with diesel or electric power of the public network thanks to the optional “Dual Power“ available on some models Continuous flow of production due to the possibility of equipment interconnection High resale value Portfolio with a wide range to meet the needs of different markets 48

of its crushers. All crushers are equipped with electric generators, which are responsible for the activation of auxiliary operations, such as conveyor belts, pre-screens, magnetic separators, etc. This concept provides a significant reduction of fuel consumption and enables the control and adjustment of the crushers according to the customer‘s needs. In this way, all equipment can be interconnected, which minimizes or even eliminates sudden interruptions in production: the equipment identify increases or decreases in feeding and automatically corrects its operating speed. Still in the field of technological advances, Kleemann offers the largest range of equipment that can be supplied with Dual Power. This option allows the machine to work with diesel or electric power from the public utility system. Thus, the customer chooses the electricity source they want to work with. This flexibility eliminates „forced outages“ of the operation caused by the inability to use public electricity use at certain peak times, or avoids extra charging on the kWh amount.
