Opportunities

1、Infrastructure construction tide keeps surging and the demand for aggregate is brisk.

2、The price of sand and stone is in a state of rising and fluctuating, and the prospect is broad.

3、There is a large supply gap in some areas, so the sand aggregate faces a huge investment opportunity.

Challenges

1、The decline of natural sand reserves led to the government's policy of limiting mining, which could not make aggregate supplied continuously.

2、The quality of mixture consisting of nature sand and concrete is decreased because the quality of nature sand is decreased, so that the construction quality is also influenced.

3、The regional distribution is uneven, and the cost of raw material collection is high.

4、Traditional sand making uses cheap jaw crusher to produce. It takes disadvantages of simple crushing, single screening and unstable quality.

Based on Japan's special design and advanced international technology, Kefid developed an integrated sand making system --VU aggregate optimization system. With the integration technology of breaking, grinding and sand selecting, VU aggregate optimization system can produce machine-made sand comparable to natural sand, which can well meet the demand of construction market.

Structure

Quality and Efficiency

VU series vertical shaft impact crusher

VU series vertical shaft impact crusher

The new type of 5 holes rotor improves collision frequency and crushing efficiency.
The comprehensive grinding effect is formed because of increased grinding block, which makes the product uniform in texture.

VU module control screen

VU module control screen

Integrated screening facilities improve production efficiency greatly.It is adjustable and controllable that makes the product fineness uniform, gradation reasonable and quality reliable.

VU shape optimizer

VU shape optimizer

he materials are crushed along the stress concentration point at low velocity impact, so that the crushing effect is good.(Material's burr is brushed away because of water-fall spiral movement,which makes the finished products well-distributed.)

Central control system

Central control system

1、Negative pressure device collects powder. It is efficient, convenient and clean.
2、The ores can be used more efficiently because it is dry and clean.

VU humidifying agitator

VU humidifying agitator

1、Automatic water adding device ensures the moisture content of the finished sand is stable and the composition is even.
2、The operation is simple and the labor cost is saved

Intelligent control device makes the operation simple and accurate.Real time monitoring and timely handling of operation problems can improve the service life of equipment.

Performance advantage

1、tower design, compact layout, efficient operation.

2、It reproduces the natural crushing, erosion friction and natural washing process in the formation of natural sand to a great extent, so as to improve the performance of finished sand greatly.

3、It uses gravel, cheap tailing, waste sand as raw materials and reduce the cost greatly.

4、There is an intelligent control system which can save manpower and material resources because it is easy to operate.

5、There is no dust, sewage and sludge in the sand making process, and the cost of environmental protection is low.
