Of course not. On the one hand, the VU aggregate optimization system can solve the problem of the source of high-performance sand, and make low-cost, high-performance concrete and mortar, then ensure the stable operation of mixing station, mortar system and optimize the mix ratio. On the other hand, there are a large number of 0-10mm stone chips in the gravel yard. This kind of material has disadvantages of large capacity, small market demand, low price, and even it will keep long in stock and become tailings, resulting in storage and treatment costs. Using VU aggregate optimization system can process these tailings into high value fine sand, which also saves production costs.
After understanding the VU aggregate optimization system, you may understand the importance of fine aggregate and the advantages of dry sand process. KEFID Heavy Industry is selling VU120, VU150, VU300 and other large aggregate optimization systems. Welcome to consult.
The VU aggregate optimization system is composed of VU impact crusher, particle optimizer, modulus control screen, humidifying mixer, dust collector and centralized control system. It is also equipped with hoist, belt conveyor, chute and steel frame structure.
VU vertical shaft impact crusher
VU crusher is a product specially designed for aggregate optimization system based on VSI series sand making machine. It uses a 5-hole rotor, which greatly improves the impact frequency of materials, and adds a grinding mechanism to the blanking ring to strengthen the role of rubbing and shaping. After crushing and shaping by VU crusher, the sand shaped like needle is reduced, and the finished product is round and quality.
Particle optimizer
The inner vertebral body rotates to drive the spiral movement of sand, which forms a brushing action between sand and cavity, sand and sand. The burrs and edges on the surface of sand are removed, and fine sand of 0.15-0.6 mm is obtained. This kind of waterfall brush can effectively reduce the void fraction of sand and improve the fluidity, and the effect of low energy crushing is obvious. The capacity of 60t only needs 22kW power, and the cost-effective ratio is high.
Modulus control screen
In fact, modulus control screen is the equipment that combines air separation and screen separation. If the screen is not changed, the gradation of finished sand and the content of stone powder can be adjusted by adjusting negative pressure and setting of separator.
Humidifying mixer
It makes humidification uniform, operation reliable, maintenance convenient. Specially water spraying device and water supply system with adjustable water quantity can ensure uniform material humidification and moderate water content, so that the moisture content of finished sand is qualified, and the composition is uniform.
Dust collector
Adopts negative pressure dust collector and combines with the whole process of sealing operation. Ensures that there is no dust in the site, and the environmental protection index meets the national standard.
Centralized control system
An integrated electronic control system can monitor and regulate the operation of the whole set of equipment. It can start and stop by one key, including alarm for abnormalities, emergency shutdown, automatic and stable operation parameters, etc.. which can ensure the smooth and stable operation of the system.
The VU sand and gravel aggregate system has been comprehensively upgraded on the basis of the original dry sand making system. It adopts highly intensive tower-type fully enclosed arrangement, which can effectively control dust emission and meet the environmental protection production standards. The mechanism sand has been comprehensively improved in various indexes such as grain type, gradation and powder content, making the performance of the mechanism sand comparable to natural sand.
The advantages of the VU sand and gravel aggregate system are as following:
1. High quality finished sand
The finished sand has excellent grading, grain type, powder content and other process indexes, and the performance is stable and controllable, which is comparable to high quality natural sand.
2. Low consumption and low cost
The comprehensive innovation of the grinding technology, the improvement of the performance of the single equipment and the reasonable connection of the technology have achieved low consumption; the low-cost can be achieved by using cheap tailings such as stone chips and melon seeds as materials to produce sand.
3. Fineness is adjustable
Fineness adjustment is convenient (2.2-3.2).
4. More accurate classification
The classification accuracy is more accurate than before. The same product as wet sand can be produced by adding water as mixer.
5. Process environmental protection
The equipment is fully enclosed and the dust does not overflow. The environmentally friendly dry process does not require water washing and does not cause problems such as sewage, silt and dust.
VU aggregate optimization system integrates sand production, particle shape optimization, stone powder control, gradation adjustment, water content control and green process together. It produces final sand with round shape, little powder content, as well as dry, clean and reusable stone powder.
Small covered area
Compared with the traditional sand production line, the VU aggregate optimization system is a tower type crushing line. For example, the main tower of VU120 aggregate optimization system is only 21m x 8m, which occupies a small area and saves the cost of infrastructure construction.
Long service life
Anti-wear design and quality raw material significantly prolong the service life of wear-resistant parts and greatly reduce the downtime of maintenance. The key components adopt international brands, such as impact crusher bearing using German brand FAG, triangle belt using German OPET, vibration motor using Sino-foreign joint venture brand Euler Wolong, PLC components using Siemens, etc., which can strengthen product quality.
High crushing efficiency
Using vertical shaft impact crusher with five outlets to increase the frequency of throwing and collision, and using the crushing process called stone-to stone. The Sand-Forming rate of one pass is 10% higher than that of the original impact-crushing mode.
Good quality of finished sand
VU aggregate optimization system can substantially increase the production of materials with particle size between 0.15 mm and 0.6 mm, and the finished sand meets the requirements of high standard sand in gradation, grain type and mud content. Its grain shape optimization and shaping technology is recognized as an international advanced level by China Science and Technology Achievement Appraisal Committee.
Stable and adjustable
The VU optimization system has many adjustable devices, which can adjust the air volume and pressure distribution, return volume of vertical shaft impact crusher, mold-controlled screen, etc. The gradation of finished sand is adjustable and controllable, which meets the requirements of the second zone of the national standard. In addition, once the parameters are set, the performance of finished sand remains stable, and the control process is simple and effective.
Green process
On the one hand, it conforms to the sustainable concept of waste reuse, because the source of raw material comes from a wide range and the cost is low. On the other hand, there is no dust in the production site and no need to wash, and there is no sewage sludge treatment problem.
The project adopts VU150 Aggregate Optimization System with high quality, green process and intensification. It uses integrated electronic control system and the centrifugal crushing method of "stone beating stone". Besides, it combines air separation technology with vibration screening technology, and the finished stones are shaped round and the powder content can be adjusted at any time. VU150 Aggregate Optimization System can produce manufactured sand that meets the requirements of customers, and all environmental protection indicators meet the national standards.
