100-120 t/h VU Tower-like Sand Making Plant

The project supplies manufactured sand and aggregate for expressway construction. Since a large amount of high-grade concrete is needed in the process of bridge construction, the construction unit not only have huge demand for manufactured sand, but also requires the high quality of it. However, the traditional sand-making process method has numerous defects such as large fineness modulus, high dust pollution´╝îlarge footprint and etc. Thus, the customer decided to use VU aggregate optimization system to solve the problems. After the system was put into production, the plant has been running smoothly and the output keeps stable, which has brought great economic benefits to customer.

Project Profile

Material: limestone(0-10mm)

Final Product: 0-0.075mm(stone powder),0.075—5mm(manufactured sand)

Major Equipment: VU120 aggregate optimization system

Application: Final product is mainly used as high-grade concrete material in expressway program.


1)The gravel is crushed inside VU impact crusher to eliminate the needle shaped material. This process is meant to make the grains reach the required size.

2)The crushed stones are evenly conveyed to model-controlled screen through feeder, where the materials are graded. With the gradation of manufactured sand is precisely controlled, the unqualified material is returned to impact crusher for re-crushing until the size and shape reach the requirement. Besides, the stone powder is collected by dust collection system.

3)The qualified finished product enters Humidification agitator(optional) for wet mixing to control the moisture content of the sand, which will ensure the quality of the sand in a further step.

4)The excess stone powder produced will be collected by pulse dust collector, sent to finished product tank by pneumatic conveying system, and packed through packaging system for transportation in the end.
