It plays a vital role in the work. 2. Unique structural design, the finished product is cubic, tension-free and crack-free, with good grain shape.

Usually, different types of crushers: vertical shaft impact crusher, horizontal shaft impact crusher, cone crusher and jaw crushers are used for production of …

HAZEMAG impact crushers can handle individual lumps of feed material up to 8 tons in weight and 3 m3 (100 cu.ft) in volume, effecting the comminution process in a single pass at capacities of over 2200 tons/hour. Even feed material with a high moisture content up to 15% H2O can be processed without any problems by the provision of indirect ...

Vertical shaft impact (VSI) crushers, on the other hand, are used in the last stage of the crushing process, especially when its required that the end product has a precise cubical shape. VSI crusher can be considered a 'stone pump' that operates like a centrifugal pump.

Different Fineness & Shape. a. Jaw crusher is coarse crushing equipment, the discharge size is generally large, and the size of finished product is generally 10-350mm; due to the crushing principle of jaw crusher, there are many needle and flake finished aggregate; ... Impact crusher has the advantages of large feed inlet, high crushing chamber ...

1.1 Impact crushers can be divided into two types according to the number of rotors: single-rotor and double-rotor impact crushers. 1.2 The structure of the single rotor impact crusher (Figure 1) is relatively simple and consists mainly of the rotor 5 (strike plate 4), the impact plate 7 and the machine body. The rotor is fixed to the main shaft.

• Good shape of end product • Low initial investment • High reduction ratio Feed material is reduced by: • Initial impact with blow bar (60%) • Impact with breaker plates (30%) • Inter-particle collisions Crusher sizes There are many different crusher sizes. The first two figures in the NP Series™ model

If you crush this type of rock with a cone crusher, the shape of the particles is more "cubical" compared if you do the crushing with a hammer (impact) crusher. Impact crusher obviously produces better chips for the said purpose. For more amorphic or non–oriented rocks type of crushing obviously is of lesser importance.
