Depending on the material of the output size is different, such as rock, sand and gravel, river gravel and other such materials.Metal-containing rocks are different, the shape of the sheet-like, gritty, block, also have different hardness.Sand is a quite different structure, and some particles of uniform thickness, some sizes; some good roundness debris sand, gravel and some debris sharp edges and corners.Like eggs, like river gravel stones, regardless of size.Such as small grains, such as large watermelon or greater.Sand grain size uniform made of sand and gravel production line, and the pressure is relatively high, far exceeding those of the original sand sand making production more in line with current building requirements, but also in building quality also have some protection.
First question we need to consider is what kind of stone you need to break, such as pebbles and let us know pebbles is very hard, if the direct use of sand production will cause serious Sand hammer wear, after all, the cost of replacing the hammerit is very large, so you need to use this time to be a pebble crusher crushing, sand making machine to be able to use the two-stage crushing performed after completion of crushing, the only way the particle size is perfect.
If you need large pieces of broken stone then do not hesitate to directly re-use impact crusher or stone crusher was ground after a large jaw crusher crushing them for the first time, after sifting through the sand will getand stone are two, if you only need to use two layers of stone sieve enough.
Granite, river gravel, basalt, limestone and other stone is used for sand, granite and hard texture, beautiful color, difficult to be acid-base erosion or weathering, often used in building materials.But only for hard rock crushing equipment jaw crusher capable of crushing them normally.
