above 725 tph, jaw crushers cannot compete with gyratory crushers [2]. Therefore, capacity is a significant parameter in the design of a crusher. In addition, the closed side setting (particle reject) of the crusher defines the particle size gradation of the products. Measurement of the crusher's closed side

Secondary Crushing: To refine the size of the materials from the primary crushing stage. Cone Crusher, Impact Crusher: Usually between 125 mm and 150 mm: Further reduced to 20 mm to 40 mm. The material from the primary crusher is fed into secondary crushers for a more uniform and finer size. Tertiary Crushing

Key requirements from a top performing cone crusher are aggressive crushing action, high crushing force and high power. The degree in which full use is made from this …

Impact Crushers - Secondary. The NGS Impact Crusher is extremely versatile. The most common application involves taking primary-run limestone from either a Jaw Crusher or impact breaker and reducing it into a construction grade aggregate. ... The primary curtain is generally set at a measurement equal to one-half the top size of the feed ...

The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 8:1.

The term "secondary crushing" has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed.The term should not be used, as it sometimes is, to designate …

Secondary impact crushers and cone crushers are used to further process primary-crushed aggregate, and can be operated with or without attached screening units. These crushers can be used as either …

The crusher is one of the first steps to processing the raw materials being excavated, taking large rocks and boulders and turning them into smaller, workable-sized material, and this is typically completed in two stages – a primary and then a secondary crusher. Every crusher has an ideal level measurement at which it runs most efficiently.

Single-cylinder type is suitable for secondary crushing, multi-cylinder is suitable for fine crushing. 2. If you need more aggregate than fine, you can choose a single cone crusher plant. 3. It is recommended to use a multi-cylinder …
