The Tier 4 Final-compliant Mobirex MR 110 ZSi EVO 2 from Kleemann is a slightly smaller version of the MR 130 ZSi EVO 2. EVO 2 represents the continuing evolution of the EVO line, featuring additional benefits in terms of economy and operational safety, according to the company. Size and productivity differentiate these two impact crushers. The MR 110 ZSi EVO 2 has a crusher inlet opening of 44 in., and the MR 130 Zi EVO 2 features a crusher inlet opening of 52 in. These provide feed capacities of up to 350 or 450 tph, respectively. According to Kleemann, the “S” in the nomenclature indicates a Mobirex unit with an optional, highly productive secondary vibrating screen with an extra-large screening surface that’s mounted on the discharge conveyor. This secondary screen unit can produce spec material, potentially eliminating the need for a separate screen, Kleemann says.
