The coarse material will be crushed by the secondary crusher. The fines will be taken out of the circuit. Once the secondary has finished with the ore it will be reclassified by a second set of screens with the oversize going to the tertiary crusher. The discharge of the tertiary is reintroduced to the screen deck to ensure that the ore size is ...
After the VSI crusher, the final crushed sand products are usually classified with washing equipment or air classifiers in order to reduce the fines 2 content. In secondary and tertiary aggregate crushing stages the most commonly utilised crushing equipment are cone crushers. The major advantage of the cone crusher is its ability to …
Jaw crushers are generally considered a primary or first-stage crusher. The maximum feed size can be as large as 80–85% of the crusher's gape or depth, while reduction ratios range from 2–3 times. Cone crushers are typically used in the secondary or tertiary stage after a jaw crusher has begun the reduction process earlier in the circuit.
VSI crusher RSMX series. stationary sand production. Capacity: 30 t/h - 500 t/h. Motor power: 160 kW - 400 kW. Weight: 7,500 kg - 20,200 kg. The rotor centrifugal crusher type RSMX is a high performance crusher with vertical shaft (VSI) and is used for crushing and refining of mineral materials.
During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in. ... VSI crusher. Vertical shaft impactors (VSI) have a vertical shaft and enclosed rotor that turn at high speeds. There are two main types of VSI crushers, rock-on-rock (autogenous ...
Cone crushers are similar to gyratory crushers in that they have a mantle that rotates within a bowl, but the chamber is not as steep. They are compression crushers that generally provide reduction ratios of 6-to-1 to 4-to-1. Cone crushers are used in secondary, tertiary and quaternary stages.
Vertical shaft impactors (VSI) and horizontal shaft impactors (HSI) are both types of impact crushers used for crushing materials. The main difference between the two types is the direction of the impact forces they produce. Horizontal Shaft Impactors (HSI) have a horizontal shaft that rotates at high speed and delivers a powerful impact force ...
NW7150S™ is equipped with Barmac® vertical shaft impactor (VSI) crushing unit. The VSI crushing unit produces cubical-shaped end products using rock-to-rock crushing action, where the rocks break against each other. B7150SE VSI crusher combined with the large 10 m2 (12 yd2) four-deck dual-slope vibrating screen into the same advanced chassis ...
The secondary crusher is the equipment that reduces the size of the materials further, after they have been reduced by the primary crusher. The secondary crusher has a size reduction ratio ranging from 3:1 to 5:1. The secondary crusher can be a cone crusher, impact crusher, or gyratory crusher, depending on the hardness, …
Vertical Shaft Impactors (VSI) are frequently used in mining, aggregate and quarry applications where the particle shape is critical (E.g. concrete, sand, stone and gravel). These high-speed crushers are best suited to secondary, tertiary and quaternary applications requiring the production of premium-shaped products.
There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...
Secondary crushing is the second stage in the comminution process and involves breaking down the material further into smaller pieces that can be handled by the tertiary crushers. The purpose of secondary crushing is to produce a smaller, more uniform product size that can be …

A high-quality hammer crusher can keep final material passing a twenty mesh, fifty to sixty percent passing a fifty-mesh screen. Crusher hammers are high chrome content. The hammer service life depends on the material you process. If you're running abrasive quartz, they'll last somewhere between one to two weeks.
HSI crushers can work in both the primary and secondary stages, while VSI crushers are primarily used towards the end of the crushing process as a tertiary crusher.
