ມີບັນຫາຂອງ ການວັດແທກເສັ້ນທາງການຄວບຄຸມການເກັບກ່ຽວทรายໃນแม่น้ำ ໃນແຂວງຫູນັນ ໃນປີ 2012, ການເກັບຊານດິນທໍາມະຊາດໄດ້ຖືກຈໍາກັດຢ່າງຕໍ່ເນື່ອງ. Meanwhile, traditional machine-made sand production line has such problems as poor grading, big fine modulus, mixed concrete with low strength and water pollution, etc., which incur criticisms. In light of this, LONGCHENG Inc. , the local famous manufacturer of concrete aggregate, purchased from SBM the world-class dry-type sand-making system---VU ຜະລິດຕະພັນ Optimization System and put it into use in the late 2015, absolutely solving the problems existing in wet-type sand-making system like large fine modulus, low yield and severe dust pollution.

Traditional machine-made sand production used the wet-type sand-making system which controls the stone powder content through washing gumming technology. In the process of washing machine-made sand, part of the fine particles below 0.6mm would be removed with the mud, impurities and stone powder below 0.075mm. This would cause the poor grading, big fine modulus and concrete with low strength.Meanwhile, it also reduces yield, wastes resources, and leads to water pollution, impeding clean production.
Given the heavy demand for high quality machine-made sand in Hunan and the weaknesses brought by the wet-type sand-making system, sand-making enterprises have started to search for a new technology to replace it. So this time LONGCHENG.Inc. selected SBM’s VU ຜະລິດຕະພັນ Optimization System which uses unique dry-type sand-making technology. It avoids the problems in wet-type technology and can process the high quality machine-made sand to replace natural sand. The VU system, therefore, has won high praise from cooperative enterprises in Hunan.

Transportation, storage and packing: The redundant stone powder is collected by the pulse dust collector and then sent into the finished product tank for storage through a pneumatic carrier. Finally, the final products are transported after being packed.
After fully understanding the customer’s conditions, we finally worked out a proper layout scheme after discussing the specific situation, conducting design and evaluating the scheme. It ensures a suitable, economical and profit-maximized production line customized for the customer.
SBM ได้พัฒนาระบบปรับแต่ง VU ຜະລິດຕະພັນ Optimization System อัตโนมัติเต็มรูปแบบ ซึ่งออกแบบมาเพื่อตอบสนองความต้องการในการตรวจสอบระดับการจัดอันดับ/โมดูลัสความละเอียดและปริมาณผงในทรายที่ผลิตด้วยเครื่องจักร ซึ่งสามารถแก้ไขปัญหาที่เกิดขึ้นในกระบวนการปรับแต่ง รวมถึงการบด การขุดและการแยกออกจากกัน
SBM has a skilled and experienced after-sale service team. All members are earnest and innovative. So far, thousands of engineering projects have accepted the installation and commissioning service. Meanwhile, SBM would help customers train their operating staff until they can operate the production lines independently.
In order to make customers understand the machine maintenance and repair, SBM supplies customers with the machine instruction manual that shows the detailed analysis of the machines and marks each part. It not only helps customers know the machine structures but also makes the part replacement easier.
The whole VU ຜະລິດຕະພັນ Optimization System production line offered by SBM is compact structurally and reasonable on design. This production line achieves maximizing productivity and minimizing operation costs. The whole production process is dustless and the redundant stone powder is recycled. The produced stone and sand have perfect grain shape. The sand grading is satisfying. So concrete preparation in the mixing plant is very stable and reduces the use of cement. The cost of production is, therefore, reduced.
Grading: For dry-type sand-making system, after the powder separating machine, the soil particles in the artificial sand can be removed and the sand can meet the standard for construction. Besides, the stone powder content in artificial sand can be controlled by the powder separating system under the national regulations so that the compressive strength and mixability of concrete can be increased. For wet-type production, in the process of sand-washing, the washing sand would be removed with stone powder, leading to the shortage of washing sand in finished sand product and influencing the grading of sand.
Cost: The production cost of the dry-type sand-making production line is relatively low, because it uses a high-efficiency powder separator to separate sand and powder and does not require much water for washing.
Environment: Unlimited by water supply and environment, the dry-type sand-making system can produce sand in water-scarce areas. But for the wet-type sand making production line, making sand must be carried out in water-rich areas. And the production is impossible in winter in high-latitude zones.
ການປົກປ້ອງສິ່ງແວດລ້ອມ: Water in the dry-type production line is not required. The stone powder in the production can be used reasonably. So, to some extent, the water and minerals are saved. Moreover, it brings no sewage and sludge. It is more environmentally friendly than the wet-type sand-making production line.
