of today produce less flat and elongated particles than the short stroke crushers of 20 years ago. Figure 5 shows the affect of F&L with stroke. This is because the longer stroke machines allow the material to tumble more as it falls deeper into the crushing chamber with each stroke. This tumbling action breaks up the F&L particles as it promotes

THE CORRELATION BETWEEN AGGREGATE SHAPE AND …

May 13, 2019· The settings on a jaw crusher are designed to produce material ideal for secondary crushing. The best particle shape is typically found in material that is about the same size as the closed-side setting. Smaller sizes will contain a higher proportion of elongated particles because they have passed through the crusher without being touched.

How to Get Fine_sized Finished Products?

The type of crusher selected will play a role in the shape of the rocks generated from crushing, which may affect sorting. For example, jaw crushers and unloaded cone crushers will produce particles that are flat and elongated while impact crushers and choke-fed cone crushers will make more cubic-shaped particles.

flat and elongated aggregate from crusher

The percentage of flat and elongated particles has been related to volu- metric properties; therefore, changes in percentages of flat and elongated particles may be related to changes in volumetric properties. However, flat and elongated aggregate tests performed at the 5 1 ratio are generally insensitive to production changes in aggre- gate shape.

reducing elongated particles crushing

Feb 15, 2005· Rolls are used in flour milling, where crushing yields different-sized particles, allowing separation of purified flours. Moisture content is important so that, for example, the bran is soft and remains in large pieces, whereas the endosperm is brittle and fractures into small granules. Corn germ can be separated from starch and fiber by roller ...

elongated particles should be limited to a maximum of 15% by weight of total aggregate. In general, it is preferable to have somewhat equidimensional rather than flat, thin, or elongated particles. The amount of flat and elongated particles in coarse aggregate samples can be determined following ASTM D 4791 (Flat Particles, Elongated Particles,

PRIMARY CRUSHING In stone quarries or in very "boney" gravel pits, large material usually is reduced in size by either a jaw (Figure 5- 7) or a gyratory crusher. Both types are compression crushers. Although economical, they have the tendency to create thin, elongated particles. Particle shapes sometimes may be …
