Sand making machine to open the river pebble use the door

River pebbles are natural in a natural ore, the river pebbles for reasonable processing and utilization, is an indispensable step in building a green society. With the depletion of mineral resources, to take reasonable measures to improve the utilization of river pebbles is the focus of the current gravel plant, from the current market trends, the sand making machine will open the river pebble use of the door.

River gravel is an ordinary sand and gravel by the impact of floods, water transport process is constantly under the impact of the formation of the role of extrusion, during the tens of thousands of years after the evolution of the history of the formation of the river pebble high hardness, abrasion resistance, Corrosion resistance is good, the acquisition cost is relatively low, so become a water conservancy, highways, railways, bridges, construction, municipal engineering and other fields in the ideal stone, the application value is extremely high.

It is understood that many areas of China in the treatment of river pebbles there are some problems, such as waste in the process of serious waste; dust and noise and other pollution problems occur frequently; get the river gravel finished grade is low, the application area is limited.

Although the market on the river pebble treatment equipment more, but can really achieve the river pebble resources as undoubtedly sand machine equipment, the market a lot of crusher can only achieve the purpose of the river pebble broken, but broken the size of the size and Shape can not control, can not meet the industrial field on the river pebble grain size requirements, but the sand is different, it is a typical sand making equipment, the river pebbles have a very good shaping effect, the finished product more accurate The

Many processing plants in the river pebble processing, the direct use of crusher for its processing, while ignoring the importance of sand making machine in the production process caused a serious waste of resources, which led to higher and higher costs, To the processing plant to bring a huge financial burden.

Based on a lot of manufacturers do not know how to process the river pebbles, Shanghai joyal machinery company's sand machine experts recommend that for the river like pebble this relatively high hardness of gravel, the user if the finished product shape and particle size requirements are higher, the best Is the use of sand making machine for its processing.

Sanding machine with stone crushing principle, in the course of the operation will not damage the equipment parts, while the river pebble sanding better, but also in the process of running less dust, low noise, to achieve the conservation of resources And the dual effect of protecting the environment, is currently the most favored by the user sand making equipment, will be the use of river pebble resources play a vital role.

With the increase in demand for gravel in the industrial sector, the investment and utilization of river pebbles has become the current hot spot, and the upsurge of exploitation of river pebbles has been set up, which will be a kind of river pebble processing plant and mining machinery and equipment factory. New opportunities and challenges.

River pebble sand making equipment

Introduction to river pebbles

River gravel is a natural stone, the appearance of sleek, beautiful, generally as a watch, with the continuous progress of science and technology, its comprehensive utilization value has been significantly expanded, the scope of use is further improved, so far, river pebbles were applied In the construction, industry, bridges and other fields

Unprocessed river pebbles can not be directly applied, because of its shape, size inconsistent, applied in various fields unsightly, only after professional equipment can be used after processing, for the processing of such stone, we choose sand equipment, Sand equipment manufacturers are very much, Shanghai joyal machinery to high credibility, good quality equipment, cost-effective and other advantages of the majority of customers have been unanimously approved, the following we focus on the Shanghai joyal River pebble sand making equipment.


According to the characteristics and characteristics of river pebbles, river pebble processing equipment mainly sand machine, sand washing machine and vibrating screen, the following three devices in a detailed description:

1, sand making machine

Sand making machine, also known as the impact crusher, the equipment for the river pebble processing main advantages reflected in the high production efficiency, Shanghai joyal production of sand making machine in the structural design process, to maximize the efficiency of equipment for the purpose of reasonable Design, for the efficiency of each step, the process, the details are treated rigorously, especially the core components of the equipment - motor, Shanghai joyal priority to use high-quality, high-performance, low-power motor parts, this move Not only makes the operation of the equipment more perfect, but also to a large extent also improve the production efficiency of the equipment.

2, sand washing machine

Strictly speaking, sand washing machine also belongs to the sand making equipment, its function and function is to complete the sand peeling work on the river pebble, Shanghai joyal production of sand washing machine in the river pebbles sand washing process is very high degree of cleanliness, And the handling capacity is very large, which also stems from the well-designed equipment, Shanghai joyal attaches great importance to scientific and technological research and theoretical innovation, sand washing machine processing into a very high technological content, while the equipment selection will pay special attention, We use a high hardness, high strength, high density metal material for the chassis design, excellent chassis parts can protect the internal parts from damage, but also can extend the service life of the equipment.

3, Vibrating Screen

Vibrating screen is generally the auxiliary equipment in the process of sand making. Its function and function is to complete the filtering effect on the river pebbles. The performance of the vibrating screen produced by Shanghai joyal is very advantageous, and we adopt a unique design to carry out reasonable layout, especially The equipment of the screen, spring, motor system deployment, which makes the device has a filtering effect is good, durable, low operating noise advantage, these advantages make the equipment sales and turnover rate has been significantly improved.

Why can not sea sand for real estate construction

Natural sand scarcity has become more and more people's consensus, the river can not meet the market demand for sand and gravel, can only start from the machine sand, which also makes the mechanism of sand in recent years more and more hot, the system of sand production line has become A lot of gravel plant competing to buy products, high-quality sand production line equipment is more manufacturers of sand and gravel in the small and medium enterprises in the stand out of the magic weapon.

Some people questioned, since the river sand less and less, can not meet the natural sand and gravel demand, why not sea sand? The existence of sand is certainly a lot of sand, and there is no river sand excavation damage to the river environment, there are security risks and other issues, can not be used for infrastructure construction?

Joyal machinery sand and gravel experts tell you the answer, not desalinated sea sand can not be used as building materials. This is the state strictly prohibited, why is this?

We all know that with the continuous development of society, now the real estate construction are mostly made of sand and concrete reinforced concrete construction, although the sand itself is pure, low mud content, but because of its moisture and a large number of free chlorine Ions and other acid ions, when they are used in reinforced concrete, these free chlorine ions will corrode the steel, resulting in expansion of steel, which caused the structural components of their own expansion and deformation, bearing capacity decreased, seriously affecting the safety of the building.

The damage caused by the desalination of the sea sand to the rebar is very serious. If the acid ions such as chloride ions are corroded, the steel bars are getting thinner and the mechanical properties are decreasing and the yield strength and elongation are significantly decreased. A large number of water molecules, easy to make steel rust, reinforced rust after the expansion of the volume, will burst around the concrete, resulting in cracks, serious and even lead to the surface of the concrete off; ribbed steel to rely on the surface of the crescent-shaped ribs Concrete anchored together, like the screw on the thread, not easy to fall off, once the steel corrosion, crescent-shaped thread corrosion damage, ribbed steel bar into a smooth cylindrical, anchor performance significantly reduced.

Desalination of the sand can be used for construction, but the high cost of desalination desalination, and the process requires a higher. Although there are some areas have used sandals as a precedent for concrete ingredients, but the fact that there is indeed a reduction in the use of the building life. Before the domestic river sand is unregulated state, easy access, and now the cost of sand is not high, and the safety is relatively high, so rarely use sand.

Through the above description, I believe we have to understand why the sand is not used for construction, more information on aggregate aggregate, please contact the Red Star machine to understand the consultation.
