Pick Sand Making Machine According to Your Requires

Sand is one of the important elements of concrete and sand pulp, and it is also the basic raw material of civil construction and engineering. It might be divided into naturalquartz stone used in glass manufacturing sand and artificial sand. Organic 1 is formed in nature condition (mostly from rock weathering). Typically, we call it pure for the rock grain size is beneath 5mm. Artificial one is produced sand, which refers for the rock grain size significantly less than four.75mm which has been processed and screened by crusher machines. The common one is divided into 3 kinds of coarse, medium and fine according the modulus of fineness. Coarse: the modulus of fineness is three.7 three.1, the typical size is above 0.5mm Medium: the modulus of fineness is three.0 2.3; the average grain size is 0.5 0.35mm Fine: the modulus of fineness is two.two 1.six; the typical grain size is beneath 0.25 mm. The modulus of fineness is finer, the sand is coarser. The range of modulus of fineness for normal concrete sand is 3.7 1.six. The medium size sand is improved. Or it is possible to mix tiny fine sand to coarse sand, along with the mixing proportion is four:1. The grain composition of sand refers to proportion. The space cavity of two exact same sized is substantial, and it will be smaller underneath the condition with the proportion of two various grainsizes; it will be smaller if you'll find 3 kinds. So, the rate of space cavity will depend on the proportion of different grainsize. It could save cement consumption, and increase the density and strength of concrete and sand pulp if the proportion is effectively. Machinery generates a wide range or we are able to also call it vertical shaft , with all the advantage of low consumption, price helpful, the final product size is shaped nicely and low iron and dust pollution. Its fineness size is often adjusted, so the sand and gravel proportion is nicely, that's suitable for giving aggregate to highway, railway, civil engineering,...
