Figure 5.1 Schematic diagram of a crusher showingg the open- and closed-side settings. 5.1 Jaw and Gyratory Crushers. Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size.
60% of the crushing in an impactor will be done on initial impact with the blow bars and the primary apron. Then the secondary apron will do 30% and finally the tertiary apron kicks in and does the final 10%. Back to the primary setting. If you squeeze that down and close the gap up you will reduce your production.
HSI crushers can be primary or secondary crushers. In the primary stage, HSIs are better suited for softer rock, such as limestone, and less abrasive stone. In the secondary stage, the HSI can process more abrasive and harder stone. ... With proper choke-feed, cone-speed and reduction-ratio settings, cone crushers will efficiently produce ...

Selecting the right primary crusher is foundational to success at a crushing site. The primary crusher is the engine that drives the rest of the plant; it's the workhorse that takes blast feed sizes and reduces them to sizes that are manageable for other site components – the belts, the screens, and eventually any secondary crushers – on the road to a finished product.

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.
Secondary impact crushers are vital tools in the aggregate and mining industries, designed specifically for the second stage of crushing. After the initial reduction by a primary crusher, these machines take the coarser input material and further reduce it to the desired size, shaping the particles into a more cubical or uniform form.
Learn about the different types of secondary crushers, including impact crushers, cone crushers, roll crushers, and jaw crushers, and their functions, advantages, disadvantages, applications, and factors to consider when selecting them. Discover case studies and examples of successful applications, as well as future developments in secondary crusher technology.

Where the material is not reduced sufficiently in the primary crusher, it is then crushed by a secondary crusher to achieve the correct size of the material. Wear on parts of the crushers affect the performance and volume of material being crushed, the parts subject to high impact, and abrasive wear include the hammers, rotors, teeth, and mantles.
In the secondary crushing phase, machines play a crucial role, expertly managing materials from primary crushing. These pieces, usually between 150 to 300 mm, are fed into secondary crushers. These crushers are built to handle these sizes, aiming for a consistent range of smaller pieces. Secondary crushers vary in size and gradation.
