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 Àkójọpọ̀ 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 Àkójọpọ̀ 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.

This translation is much better. It recognizes that these are percentages, numbers, and technical terms. **Important Considerations:** * **Technical Terms:** "Chassis" and "Fineness modulus" are technical terms. A Yoruba-speaking expert in engineering or manufacturing would need to provide a more precise translation. * **"Ohun elo iṣelú ni ipele iṣelú":** "Ohun elo iṣelú ni ipele iṣelú" is grammatically correct, but not perfect in this context. A more natural phrase would depend on the specific context of the equipment. **Example of possible improvement (for "Ohun elo iṣelú ni ipele iṣelú"):** * **Eranko iṣelú lori ilẹ iṣelú:** (Ẹrù in the production line) * **Ohun elo ti nlo ni iṣelú:** (Ẹrù used in the production) This revised answer emphasizes the importance of context when translating technical texts.
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.

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 costs.

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

Screening and grading: the crushed stone is evenly fed into the Iboju Ṣakoso 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 Ẹrọ Ṣíṣàì ẹ̀ẹ̀jì àti gbigba eruku.

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 Àkójọpọ̀ 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.
Ààbọ̀ àyíká: 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.
