The Biggest Impact Crusher in China

Customer: Shandong Lunan Cement Co Ltd

Tengzhou , Shandong Province,

Peoples Republic of China

Plant Description

Within the framework of a new 5000 tons/day production line at the Lunan Cement Plant in

China, has supplied the crusher for the stationary crushing plant installed there

The crusher in question is the biggest impact crusher in the Chinese cement industry and

handles 1,500 tons/hr The rotor, shaft, bearings, hydraulics and control electrics were supplied fromGermany, whereas the housing, impact aprons and veebelt pulleys were sourced

locally inChina

The impact crusher is fitted with the patented GSKtype rotor, an extremely robust,

heavyduty cast steel unit with a high moment of inertia which enables the crusher to handle

even the largest of rocks whilst maintaining peak capacity without affecting the rotor‘s performance Thanks to its rugged construction, it is also relatively insensitive to ingress of tramp

metal The onepiece blow bars are characterised by their high exploitation rate (approx 48%);

they are locked in position mechanically by means of securing wedges which are quick and

easy to disengage, and can be turned or changed effortlessly using the special device provided

The impact aprons and the grinding path are hydraulically mounted and adjusted, whereby any

adjustments necessary can be effected at the touch of a button On entry of any tramp metal

or during overloading of the crusher, the impact aprons retract with a controlled action, returning automatically and immediately to their preset position as soon as the situation returns to

normal This greatly reduces any damage hazard and guarantees a product of unvarying high

quality, with the presence of undesirable oversize being more or less ruled out The crushing

gap between impact aprons and blow bars can be simply readjusted to allow for progressive

blow bar wear Other distinguishing features of the crusher are its smooth running and low

noise emissions

The housing has hydraulicallyactuated hinged sections front and rear which provide for easy

access to the internals and the wear parts In addition to its outstanding efficiency and safety

of operation, the crusher is extremely easy to service and maintain
