A cone crusher is a type of crusher that is commonly used for processing rocks in mining and aggregate applications These crushers use compression force to break large rocks and other materials into smaller rocks gravel and Since its inception the live shaft cone crusher design is highly regarded as the benchmark for reliable hard rock cone crushing and its robust
RQD <70 >40 The ore or rock type is considered to be less competent and amenable to semi autogenous grinding without a pebble crusher The pilot plant was run with a primary autogenous mill and a secondary pebble mill New feed was run of mine ore and pebbles were extracted from the primary mill for media addition to the secondary mill
Photo The Trio® TC84XR cone crusher Pebbles contain valuable ore but without a crusher capable of processing them pebbles can end up discarded or stockpiled Weir Minerals has developed the Trio® TC84XR cone crusher specifically engineered to perform in the most challenging applications including pebble crushing Pebble crushing is one of the toughest
Grinding is one of the most energy consuming processes in the mining industry As a critical part of the comminution process autogenous grinding AG or semi autogenous grinding SAG mills are often used for primary grinding However the breakage mechanism of an AG/SAG mill is inefficient in grinding particles of a certain size typically in the range of 25 55 mm
2 Is it a primary secondary or tertiary crusher with primary crushers accepting the largest size material for reduction of course These factors along with the crusher s type jaw impact gyratory etc will give you an idea of how many tons of rock can be processed per hour through the crusher based on some mathematical computations
