Cutter crushers
Features & Benefits Hydraulic rotation »More versatility on narrow sites
Good kinematics »More performance »Ability to break large particles
Changeable wear parts »Reduced down time »Savings
Hardfacing »More life time
Cutter crushers
Features & Benefits
►
Increased productivity. »Hydraulically controlled rotation provides enhanced initial positioning of crusher to target (hydraulic rotation is by-passed, when crusher is in contact with target).
►
More versatility on narrow sites. »It is also easier to sort material (e.g. rebar) and effective in narrow spaces.
Hydraulic rotation
Cutter crushers
Features & Benefits
► ►
Reduced down time Reduced expenses of consumables »Four cutting edges are available in symmetrical cutter blades. Easy service on site. Special fastening system secures cutter blades effectively.
Cutting blades Easy to replace or turn
Cutter crushers
Features & Benefits
►
Increased productivity. »The stopper nipple in the jaw prevents iron scrap from slipping out of the cutting blades.
Cutting design Nipple
Cutter crushers
Features & Benefits
►
Increased productivity. »Crushing is most effective, when height of the material to be broken is approximately 70 % of maximum jaw opening.
►
Ability to break large parts »Jaw opening and usability of crusher were main design criteria.
Jaw kinematics
Cutter crushers
Features & Benefits
►
Less downtime »The trunnion supported cylinder (= center mounted cylinder) is effectively protected by the jaws. Protection is required due to of iron rebar protruding from the concrete and because crushers usually work in narrow places.
►
Less service costs »The induction hardened piston rod is resistant against falling debris.
Hydraulic cylinder Well protected
TWO CYLINDERS: Only as powerful as one cylinder. Heavy construction and expensive to maintain. Cylinders are difficult to protect.
Cutter crushers
Features & Benefits
►
Long working life »Robust structure and closed structure without needless cavities in body, allows secure use.
►
Less down time and service costs »Hardfacing is essential to increase life time of the crusher.
Reinforced construction Robust, closed structure Robust cutting blade seat Harfacing
Cutter crushers
Features & Benefits
►
Better productivity »The convex shaped breaking tooth stays sharp longer. The teeth are welded to the jaws to eliminate breakening of fasteners and required maintenance.
►
Less downtime and service costs »The tooth material is a special steel. Secure fastening by welding
Optimized tooth design
