Sample testing is required through every stage of mining, ranging from the first grab sample of an exploration survey right through to the smelter. Lab crushers are the first step in the sample preparation procedure and prepare the sample for pulverizing. For example, Rocklabs “The Big Boyd Primary Crusher” (pdf), which is a scaled up version of the very successful Boyd Crusher can accept a lump size up to 150 mm (6 inch) and crush that down to 95% passing 10 mm or even finer, and is key to lab preparation procedures and accurate sample splitting.
