vu120 machine-made sand production line in shijiazhuang

vu120 machine-made sand production line in shijiazhuang

Designed, manufactured and installed by SBM, this VU120 machine-made sand production line in Shijiazhuang was put into use in February, 2015. Its establishment plays an important role in relieving shortage of natural sand, protecting environment and developing green building materials and green mines.

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, which can optimize and adjust the indexes like the particle shape, grading, powder content and fineness modulus so that machine-made sand can completely replace natural sand in concrete and mortar preparation. The performance of machine-made sand gets improved and the cement and the cement and additives can be saved a lot.

Since the launch of Technical Regulations of Concrete Prepared by Machine-made Sand by China's Ministry of Housing and Urban-Rural Construction (MHURC) in 1973, machine-made sand has been developed extensively. Besides, the development of machine-made sand is deeply influenced by the macro-control policy, industrialization, B&R initiative, urbanization and ecological management.

The cost for quarrying natural sand gets higher and higher while the amount gets less and less because of excessive quarrying. Natural sand is non-renewable resource, so, to keep natural terrains and protect river wall as well as the ecological balance, the natural sand quarrying has been prohibited in some regions.

The sand produced by VU meets the standards of GB/T14684 and JGJ52. The sand can be adjusted according to the practical requirements. The fineness modulus can be controlled within 2.0-3.5; the powder content 3-15%.

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.

VU Aggregate Optimization System is a scheme system designed to produce high quality machine-made sand, which overcomes the problems in the sand-making technology including crushing, grinding and separating.

The new generation of VU Sand Making Machine firstly realizes the grinding technologies including high-frequency "stone hitting stone" and "material cloud". Compared to VSI Sand Making Machine, the VU the system increases the sand rate and fine sand rate by over 10%.

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.

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%.

Imitating formation principle of natural sand, the machine adopts the global pioneering technologies of "low energy crushing and dressing" and "self-grinding via falling mode" .,which can validly remove the edges on the surface of final products and increase the volume of fine sand about 0.6mm, the voidage reduces 1-2%, the flow time 5%.

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 reduce labor intensity and operation cost.

The controlling and monitoring tasks of all machines are integrated into the central control system, which greatly simplifies the operation process and ensures the safe, continuous and stable production.

Setting and keeping the optimal operating parameters is available. And the quality of products is stable. This system can maximize the productivity and keep the overall efficiency at the highest level.

After being crushed and shaped by the VU Sand-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 humid environment. Processed by VU Aggregate 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 Aggregate 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 sandstone, cement and concrete industry are created.

A. Environmental technology: The fully closed transportation and production and the negative pressure dust removing design avoids raising dust in production sites. The dry-type production and screening technology avoids the emission of waste water and slush.

B. Environmental operation: Moisture Content Control Machineoptionalkeeps the water content of finished sand product 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.

A. Efficient production: 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. Efficient operation: The intensive tower-like design occupies smaller floor areas. For example, an area of 7.5m24m can place the body part of VU70. The new anti-abrasive design and the upgrading of materials prolong the life span of wear-resistant parts and reduce the maintenance downtime a lot. The integrated control system and online adjustment design can adjust the system settings in operation, increasing the quality and yield of finished sand product and reducing labor force.

A. Reasonable grading: 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 ASTMC33the secondary level of Chinese standard JGJ52 and Indian standard IS383.

B. Smooth particle shape: 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 decreases obviously and the fluidity is therefore increased.

C. Controllable powder content: dry-type powder removing technology keeps powder content of finished sand product (0-0.15mm) stable and controllable within 3-15%. The dry and clean stone powder got by dry-type separation method can be recycled.

The raw materials are relatively clean low-value stone chips with fineness within 0-5mm and 5-10mm. The 0-5mm stone powder before being processed is 4 yuan per ton while the processed high-quality machine-made sand is 45 yuan per ton with the value of tailings increasing by 40 yuan per ton.

Sand produced by VU system can completely replace natural sand to prepare C20-C60 concrete and other special kinds of concrete. The machine-made sand has high strength, wide applicable performances and can save the use of cement and additives.

2. Receiving related data of VU system, the plan for installation must be enacted in advance. According to the size of each part, it is necessary to plan what we need in every installation process like the spare parts, materials, tools, cranes, staff and time so as to greatly reduce the time and cost for installation and to ensure the finish of project on time.

3. 10-20 workers are required to form an installation team. And they must have over 2-year experience in machinery and steel industry. Besides, after the security training, they have a strong conscience of self-security. Moreover, related skills must be grasped well. Before working, they must wear all protective appliance like work clothes, safety helmet, safety shoes and gloves. Meetings about safety and quality requirements are held in advance and each individuals working responsibility is assigned. The progress of project and related problems would be taken down every day and regular project meetings are held.

The project using sand and gravel tailings to make high-quality sand was offered by SBM. SBM offered both equipment and installation service. The whole process of installation was successful and VU120 system was put into operation on schedule. The operation was stable with little noises and no dust. The most important thing was that using the wastes produced by previous production to make valuable products brought us great economic profits.

Since the launch of Technical Regulations of Concrete Prepared by Machine-made Sand by China's Ministry of Housing and Urban-Rural Construction (MHURC) in 1973, machine-made sand has been developed extensively. From construction industry to road, railway, water & electricity, metallurgy systems, from blocking and protecting projects to bridges, tunnels and water works projects, from masonry mortar to common concrete, reinforced concrete, prestressed concrete, pump concrete, airtight concrete and combined bolting and shotcrete, machine-made sand can be seen everywhere.

In light of the protection to natural resources and the increase of construction quality, machine-made sand gradually becomes the key of dry-mixed mortar. Machine-made sand as the new construction sand for dry-mixed mortar has a significant impact on the integrated use of resources.

High cost: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 over-use of cement. And then production cost raises.

Technical defects:Because the technologies like crushing, screening, dust-removing by rinsing are too simple, the quality of finished sand product fails to pass standards on the one hand and how to treat sewage and sludge is a problem on the other hand.
