In order to satisfy the increasing demand for high quality sand and the performance requirement of concrete and mortar, SBM spent 5 years developing VU System at the specialized aggregate optimization test site with over 30-year experience in this industry.
The VU Àkójọpọ̀ Optimization System is a system designed to produce high-quality machine-made sand, which overcomes the problems in sand-making technology, including crushing, grinding and separating.
Nínú iṣẹ́-ìṣòwó yìí, VU Àkójọpọ̀ Optimization System ṣe àwọn ìwọ̀n gbogbo ti ìṣelọ́pọ̀ ègúnlọ́gìlọ́gbọn onísán fún oníṣẹ́.
------Gíga Èrè tí a Ń Ṣe Àlùkò
The new generation of Ẹrọ Ṣiṣelọ́pọ̀ Ègúnlọ́gìlọ́gbọn VU firstly realizes the grinding technologies including high-frequency "stone hitting stone" and "material cloud". Compared to VSI Àlùkò Making Machine, the VU system increases the sand rate and fine sand rate by over 10%.
-----Gíga Èrè
The combination of crushing, screening and powder separating, the screen can finish material screening and stone dust removing at the same time because of its full closure, dust removal using negative pressure and uniform screening.
-----Àwọn ohun èlò tí a lè yípadà ati ṣakoso
Wind volume and flow duct can achieve continuously online precise adjustment without replacing the screen mesh and other parts. The fineness of final sand is controllable within 2.5-3.2; the powder content within 3-15%.
-----Ṣiṣe àwọn ara afẹyìn ní àrã
Imitating the formation principle of natural sand, the machine adopts globally pioneering technologies of "low energy crushing and dressing" and "self-grinding via falling mode", which can effectively remove edges on the surface of final products and increase the volume of fine sand to about 0.6mm. The voidage is reduced by 1–2%, and the flow time by 5%.
------Iye owo kekere
The new and targeted dressing technology reduces the energy consumption and extends the life span of vulnerable parts (under the same conditions, the life span is over ten times of impact crushers).
Automated control design guarantees stable water adding to keep the eligible water content of final sand and uniformity, and to avoid segregation.
------Greener
The use of negative pressure dust collector and the closed operation boasts less dust and pollution, fully in line with national standards of "green" construction.
------Ọlọ́gbọ́n sí Ijù
The design of automatic monitoring and material discharging of fine ore bin makes the fine material storage and transportation possible by pressing a button. It greatly reduces labor intensity and operation cost.
------Ṣìṣẹ́ ati Rọrun

------Agbara Gídígìdí
Setting and keeping the optimal operating parameters is available. And the quality of products is stable. This system can maximize productivity and keep the overall efficiency at the highest level.
After being crushed and shaped by the VU Àlùkò-making Crusher, the tailings below 10mm as raw materials are divided into three components under the action of FM Control Screen and Dust Collector--- stone powder, reverting material and finished sand product. Stone powder is collected by Dust Collector and stored at the fine ore bin while the finished sand product enters the Particle Shape Optimization Machine for further dressing and then is taken the last processing step--- mixing in a humid environment. Processed by VU Àkójọpọ̀ Optimization System, raw materials can be turned into high-quality sand with reasonable grading, smooth shape and controllable powder content, and dry, clean, recycled and high-quality stone powder (Application fields depend on raw materials).
The VU Àkójọpọ̀ Optimization System---- a world-leading dry-type sand-making system designed by SBM for machine-made sand production of Shijiazhuang Hengxin Jinshuo Construction Material Company was upgraded fully on the basis of the existing dry-type sand-making system. The use of highly-intensive fully-closed tower-like layout integrates the high-efficiency sand-making system, particle shape optimization, stone powder control, grading adjustment, water content control and environmental protection. Not only does the productivity increase a lot, but also all standards including particle shape, grading and powder content improves so that the performance of machine-made sand can be compared with natural sand and new chances and value in the development of the sandstone, cement and concrete industries.
Gígbàdúró Ayíká Àgbàyanu
A. Ìṣàdánwò ayíká: The fully closed transportation and production and the negative pressure dust removal design avoid raising dust in production sites. The dry-type production and screening technology avoids the emission of waste water and slush.
B. Ìṣiṣẹ́ ayíká: Ẹrọ Ṣakoso Iyọnu Àdàpọ̀（optional）keeps the water content of finished sand products qualified and avoids raising dust. The powder storehouse monitoring and automatic telescopic material discharging design prevent the stone powder from spilling in transit. Besides, the dry-type dust removing and separating technology keeps the dryness and cleanness of stone powder, making the treatment and overall utilization easier.
Agbara Gíga
A. Ṣiṣejade tó dára: The all-around innovation of crushing and grinding technologies increases the sand production rate by over 10%. The integrated dry-type screening technology elevates the screening efficiency obviously, and the screen area can be reduced by over 50% compared with that of traditional technology. The performance improvement of single machine and the reasonable use of technologies reduce the electricity consumption a lot and increase the processing volume by 5-10%.
B. Iṣẹ tó dára: The intensive tower-like design occupies smaller floor area. For example, an area of 7.5m×24m can place the body part of VU70. The new anti-abrasive design and the upgrading of materials prolong the lifespan of wear-resistant parts and reduce the maintenance downtime a lot. The integrated control system and online adjustment design can adjust the system settings during operation, improving the quality and yield of finished sand products and reducing labor.
Didara Gíga
A. Ṣiṣe àtòtọ̀n tó yẹ: Integrated crushing & grinding functions and flexible screening design make the grading of finished sand product continuous, adjustable and controllable. The fine sand within 0.15-0.6mm increases sharply while the coarse sand with fineness within 2.36-4.75mm reduces relatively. The grading meets the American standard ASTMC33, the secondary level of Chinese standard JGJ52 and Indian standard IS383.
B. Apá àlùkò tó dára: Completely original grinding and material falling shaping technologies mainly produce square and spherical sand. The edges on the sand surface are reduced to the extreme. Meanwhile, the superficial area and voidage decrease obviously and the fluidity is therefore increased.
C. Ṣíṣe àkóso nínú iye èyìn tó wà: dry-type powder removing technology keeps the powder content of finished sand products (0-0.15mm) stable and controllable within 3-15%. The dry and clean stone powder got by dry-type separation method can be recycled.
Èrè Gíga
Highly-efficient system design reduces electricity consumption by 5-10% and labor cost by 40%. The one-time investment can save costs over 30% in comparison with similar products.

Ìdàwó gíga: Because of the continuous quarrying, the sand resources get fewer and fewer. The demand exceeds the supply so that the price increases sharply. Furthermore, because the supply and quality of sand cannot be guaranteed, the laboratory has to adjust the mix proportion frequently, which usually gives rise to the overuse of cement. And then production cost rises.
Àṣìṣe ẹ̀dá-ìṣẹ́: Because the technologies like crushing, screening, dust-removing by rinsing are too simple, the quality of finished sand products fail to pass standards on the one hand and how to treat sewage and sludge is a problem on the other hand.
