With new specialised geometries, a 1,000 hp rating, greater structural strength and proven technologies, the newly launched CH890 and CH895 are designed to increase performance in both secondary and tertiary/pebble crushing applications, according to Sandvik.

The specially designed, strength-optimised topshell and dedicated crushing chambers of the CH895 model make it “ideal for tertiary and pebble crushing” while the CH890 topshell and crushing chambers are dedicated to secondary crushing. Both units have more power and increased crushing force in order to increase productivity. Manfred Schaffer, President Surface Mining at Sandvik Mining and Construction said: “It is the specialised geometries and smart crushing features that uniquely drive efficiency and throughput.”

The new mainshaft, made from a new high-strength material, is designed to withstand harsh mining requirements while the strength-optimised bottomshell design allows for greater loads. According to Sandvik, the heavy-duty structural design ensures durability and longevity in the most demanding conditions. Further customer improvements, for increased safety and minimised downtime, include a relocated external dump valve and a new over pressure system to keep the lubrication oil clean, thereby increasing time between service. Customers will also recognise the hydraulically adjusted mainshaft and proven ASRi^TM control system to facilitate online adjustment during full load and ensure peak performance is maintained.
