Stone crusher for railway projects of 16-31.5mm crushed stone and 10-16mm crushed stone

When calculating the mix ratio of the stone materials used in railway projects, the common particle sizes of crushed stone aggregates are divided into: 5mm, 10mm, 16mm, 20mm, 30mm, 31.5mm; common stone crushers used in railway projects include jaw crusher and cone crusher, impact crusher, sand making machine, etc.
The jaw crusher is used for coarse crushing (discharge more than 10cm); the cone crusher and impact crusher are used for medium and fine crushing (discharge more than 1cm). The difference is that the cone crusher is suitable for crushing hard rocks such as granite, basalt and river pebble. The impact crusher is suitable for crushing limestone, dolomite and other medium and low hardness materials; if further shaping is required to make sand, a sand making machine is needed for fine crushing, shaping and mechanism sand production (1-5mm).
The above is a common classification of the discharge size. In fact, the stone crusher of 5-10mm, 10-16mm, 16-31.5mm and other specifications for railway projects can also choose the slightly larger model of the HPT cone crusher. In addition to crushing, it can also have a certain shaping function. Because the HPT cone crusher adopts the proprietary lamination crushing principle, the proportion of cubes in the finished product is significantly increased, the needle-like particles are reduced, and the gradation is more reasonable.
