If the output of this crushing process should have less material of the +1-in. size, the larger crusher could be operated with a closed circuit. That is, the oversize in the output could be recirculated through the roll crusher without exceeding the rated capacity of the crusher. Then all material leaving that crusher with a 1-in. setting would ...
f) Select the relevant crusher from the capacity tables =CV228. TONNAGE THROUGHPUTS It is vitally important that the correct size of crusher is selected for the required application. Be aware that when operating the crusher in closed circuit, the total crusher load needs to be used in calculations (raw feed plus return feed).
A crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.

Size reduction control of cone crushers has received fairly little attention over the past few decades. Consequently, the most common control objective is still to regulate the crusher load (crusher power or crusher main shaft piston pressure) or the closed side setting (the shortest distance between crushing liners), not the actual size reduction.
4. Crushing may be done in open circuit or closed circuit. In open-circuit crushing, undersize material from the screen is combined with the crusher product and is then routed to the next operation. In Closed-circuit crushing, the undersize from the screen is the finished product. Following are the flow sheet diagrams of open & closed circuit:
This method applies to other crushers where a control variable is available The crushers are the last size reduction stage in the value chain. Over crushing is common. The connection between crusher setting and yield is often unknown The rock cannot be repaired. We need to control the crusher carefully.

Crushing may be in open- or closed-circuit, depending on the required product size distribution. Two basic crushing flowsheets are shown in Figure 6.1: (a) the older style ("traditional") 3-stage crushing circuit ahead of a rod mill, and (b) the more modern open-circuit primary crushing prior to SAG milling with crushing and recycling of "critical size" material (see Chapters 5 and 7 ...

The product of crushers with large throws, and lower eccentric speeds, will vary more widely, depending to a much greater extent upon the nature of the material. In judging the relative merits of crushers which are rated at their close-side settings, a check should be made to determine just what kind of product the crusher will deliver, with ...

Jaw crusher feed should be pre-screened using a grizzly screen prior to crushing, to remove material finer than the closed side setting (CSS). Efficiency tips In practice, many jaw crushers are not fed to their design capacity; this is because the subsequent processing plant does not have sufficient capacity to handle the volume of material ...
reduction through the crusher and end product shape. Closed side setting (CSS) The closed side setting has a significant effect on the product gradation, capacity, and power draw of an MP cone crusher. The closed side setting is measured from the bottom of the mantle to the bottom of the bowl liner at their closest point during the gyrating cycle.

Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher. The feed size to a secondary crusher is typically in the range of 50 mm to 250 mm (up to 300 mm). If the capacity is higher, the acceptable feed size gets larger. After crushing, the product is in the range of 0-60 mm (75 mm ...
