VSI sand maker, also called VSI crusher, is the major machine for sand making plant.
Ball mill is the key machine to grind the crushed materials. Ball mill machine is widely used to process cement, silicate product, building material, refractory material, fertilizer, ceramics and glass, etc.
On the basis of domestic mills, fote raymond mill is produced. The raymond roller mill enjoys the features of high working efficiency, low energy consumption, small floor space and small cost.
The use of eps beads revealed sufficient early age strength at the same time the utilization of quarry dust in epsfoam concrete led to a more than 30 increase in compressive strength compared to the epsbased mixtures two hundred and fiftysix trial mixes were produced to examine the physical and mechanical characteristics of epsfoam
The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries by replacement of quarry dust the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity the availability of sand at low cost as a fine aggregate in concrete is not suitable and
