Rule #2: Determine desired product size. Your closed-side setting (CSS) of the crusher determines the desired product size that will be produced. The CSS is the minimum distance between the jaw liners at the bottom of the crushing chamber when in operation. For example, a 40- x 51-in. jaw crusher calls for a maximum feed size of 32 …

A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".

crusher [2], [8]. The size of a jaw crusher is usually described by the gape and the width, expressed as gape x width. Jaw crushers range in size up to 1680 mm gape by 2130 mm width. This size machine will handle ore with a maximum size of 1.22 m at a crushing rate of approximately 725 tph (tons per hour) with a 203 mm set.

For example Figure 8 shows a typical particle size characteristic curve when a jaw crusher breaks three different hardness ores. If a ore dressing crushed ore is medium hard ore the maximum particle size (dmax) of the product is required to be value="20" unitname="mm" w st="on"> from Figure 25. ... typical crusher product size …

Sized material discharges out the bottom of the crusher on the open stroke. The product size can be adjusted by moving the pitman closer to or farther from the stationary piece of steel. The closer the pitman to the stationary piece of steel, the smaller the product size. ... The material and its characteristics, e.g., its hardness, density ...

Operating Characteristic (OC) curve provide a clear picture of how well sampling separates good batches from flawed ones. The graphs map the chances a lot passes testing (y-axis) against the quality level (x-axis), usually shown as a % of defects. This visual shows sampling performance distinguishing high vs low standard lots.

13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.
