Maintaining your jaw crusher is crucial for its optimal performance and longevity. The first step is regular inspection.
Selecting the Right Crushing Equipment | Agg-Net
Types of crushers. Most crushers used for aggregate production fall into one of three main categories/types: Compressive crushers – which squeeze the material until it breaks; Impact crushers – which use the principle of rapid impact to shatter the material; Attrition crushers – which use both impact and grinding to shear the material.
Crushing technology | Technologies | Kleemann
In contrast to pressure crushing, the impact crusher operates according to the impact crushing principle. In this process, the crushed material is picked up by a fast moving rotor, greatly accelerated and smashed against a fixed impact plate ("impact toggles"). From there, it falls back within range of the rotor.
Energy considerations in compressive and impact crushing …
The operating principle of the vertical shaft impact (VSI) crusher is shown in Fig. 2.Rock material falls down into the rotor which rotates so that the edge speed is about 50–60 m/s.The rock particles accelerate and impact the surrounding bed of rock that is formed during operation.
