By definition, basalt is an aphanitic igneous rock with less than 20% quartz and less than 10% feldspathoid by volume, and where at least 65% of the feldspar is in the form of plagioclase. Basalt features a glassy matrix interspersed with minerals. The average density is 3.0 gm/cm3.

 

On this advantage of physical characteristic,artificial basalt sand is more and more popular in middle size city on construction and roads.How to produce basalt sand on proper capacity and saving production cost always to goal of Sunstone Machinery.On August,2015,we branch new basalt sand crushing plant from 10-30 tons per hour,this series are much economic for civil construction.One crushing system will all graded aggregate size from 0-25mm for buildings,while 0-60mm for roads.This is really the way to reduce your cost,low energy consumption,less staff salary,less raw material with high efficient production,all of the stone size will be used as aggregate well.

 

The main flow of basalt sand making will be like this:

 

Raw basalt ore are feeding to primary jaw crusher.

Crushed basalt gravels send to secondary impact crusher for next round crushing.

Qualified < 40mm basalt gravels send to VSI sand making machine to make basalt artificial sand.

With matching vibrating screen group,get your target aggregate in each size from the secondary impact crusher.

All of the basalt gravels < 40mm are totally crushed to be sand with 3-6% powder content and cubic sharp.

There are also sand washing and sand recycling system for optional to meet your needs.
