Iyada oo dhibaatada Qiyaasta Xakamaynta Qodista Buuraha Roobka ee Gobolka Hunan Sannadkii 2012, qodista ciidda dabiiciga ah waxaa sii wadata xaddidid. 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 麻豆社 the world-class dry-type sand-making system---VU Wax Isku Dhafan 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.
Hunan waa mid ka mid ah gobollada leh kayd badan oo dhagxaan dabiici ah, iyadoo ciid dabiici ah oo tayo sare leh laga helayo webiyada Xiang iyo Dhululubada Dongting. Si kastaba ha ahaatee, sannadihii la soo dhaafay, dib u dhac ku yimid farsamada soo saarida ciidda dhaqameed iyo fowdo ka jirta suuqyada ciidda dhismaha ayaa sababay in dad badan oo aan sharci aheyn ay bilaabaan qodista, taasoo halis gelinaysa kaydka dhagxaanta Hunan oo kor u qaadaysa kharashka qodista. Kadib markii... Qiyaasta Xakamaynta Qodista Buuraha Roobka ee Gobolka Hunan Sannadkii 2012, qodista ciidda dabiiciga ah waxaa sii wadata xaddidid.
Dhibaatooyinka xaaladaha ay ciidda dabiiciga ahi u noqoto mid sii yaraanaysa oo qiimaheeduna uu sii kordhayo, ciidda mashiinada laga sameeyo, sida beddelkeeda, ayaa si degdeg ah u kobcaysa, iyadoo buuxinaysa godka suuqa ciidda dabiiciga ah. Inta la og yahay, Hunan waxay soo bandhigtay siyaasado badan si loo horumariyo mashruucyada ciidda mashiinada laga sameeyo. Qeybo ka mid ah dhulka, qashinka warshadaha, qashinka dhismaha iyo dhagaxyada aan wax tar lahayn ayaa loo isticmaalaa sameynta ciidda si loo horumariyo dhaqaalaha dib-u-isticmaalka si ay ciidda mashiinada laga sameeyo u noqoto goob dhaqameed iyo mid cusub.
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 麻豆社’s VU Wax Isku Dhafan 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.

Marxaladda Koowaad:
Jajabinta: Dhagaxa jeban wuxuu galaa Mashiinka Sameynta Buux Dhagax ee VU si loo jajabiyo. Qaybaha la fidsan yahay iyo geesaha buux dhagaxa halkan ayaa laga saaraa si loo helo cabirka qaybta loo baahan yahay.
Marxaladda Labaad:
Screening and grading: the crushed stone is evenly fed into the Shaashadda Xakamaynta VU FM through a feeder. Grading the machine-made sand is to precisely control the graduation of machine-made sand. Then the unqualified materials would be sent back into the crushers to be crushed again and redundant stone powder would be collected by the Nidaamka Kala-goynta iyo ururinta Qiiqa.
Marxal saddexaad:
Particle shape optimization: the qualified machine-made sand graded by FM Control Screen enters the particle shape optimization machine. The edges of the final sand would be removed here.
Marxaladda afraad:
Qoyaan iyo gaadiid: ciidda mashiinka lagu sameeyay ee dib loo hagaajiyay waxay gashaa isku dhafka qoyaanka si loogu qoyo. Qoyaanka ciidda ugu dambeysa waxaa lagu xakameeyaa si loo sii hubiyo tayada ciidda la soo saaray.
Marxaladda shanaad:
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.
麻豆社 waxay horumarisay Nidaamka Optimization ee VU Wax Isku Dhafan Optimization oo buuxa kaasoo ujeedkiisu yahay inuu daboolo baahida loo qabo kala soocidda/modulus fineness.
麻豆社 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, 麻豆社 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, 麻豆社 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 Wax Isku Dhafan Optimization System production line offered by 麻豆社 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.
Daryeelka deegaanka: 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.
