Sand & ndash; a very important element used in the construction of any structures. As a construction material sand is formed under natural conditions and due to the influence of many natural factors. In what conditions are formed deposits of sand, directly affected the ways of production.

dredger for sand mining

The Sand represents the smallest particles of rock. It can be located on the bottom of ponds, or on land that is a large part of the surface. And for its production use completely different methods.

What it takes to make production

But in order to get sand from the bowels of the earth, you need not only trucks, dump trucks, special dredge for sand mining, but the license for such activity in a certain place, because without it is illegal. License is necessary for all miners, except the landowners of garden and household plots, as well as the enterprises that deploy prey in areas on the border of the allotment of mining land.

Methods of sand mining

For each method of sand mining uses specialized techniques and methods.

The First method is dry extraction. In this approach, the sand is extracted from the quarry. It uses typical methods and equipment for open-pit mining of any minerals. To start doing drilling and then loosening with explosives and then loaded on trucks and export to the mills of the company.

The Second method involves the extraction of sand from the bottom of the body of water (lakes, rivers, shallow seas). In this case, a special design – a dredger for sand mining. Also, as an option, you can apply dlinnostebelchatye excavators, excavators with bucket wickedawesome. However, such equipment is expensive, which affects the final price of the material.

Also, extraction can occur in wet conditions when using the alluvium hydraulically. This method does not require blasting and drilling operations. It has the advantage over competitive ways – produced sand is cleaned from impurities.

Extraction of sand in shallow water

As noted above, on rivers, lakes and shallow seas used dredger for sand mining. The principle of operation is as follows: device pump sucks the sand which is on the bottom of the pond. Then he loaded into the hold of a ship or on a barge. Most convenient for this method of production are parched reservoirs.

The Dredger for sand mining has a complicated structure, which depends on the terms of use. In particular, the dredger bucket sort, is used if the soil on the ground more solid. The extracted sand is immersed and transported to a place where it is the final purification from impurities.

The design of the dredger

The Dredger for sand mining includes the required list of construction elements:

  • The Case – is an essential part for fixing all the necessary machinery, equipped with pontoons.
  • Pile camera – an important part, providing the movement of the dredger during extraction of sand and soil.
  • The superstructure – located in the Central pontoon has a deckhouse with required equipment.
  • Loosening of the device – the main part gruntoobrabatyvajushchaja complex.

  • Installation for ground transportation. Consists of several elements, is usually in the hold. Main parts, dredging pump, suction wire the actuator as a power unit and a pressure wire. The drive normally used are diesel, electric or diesel-electric drive.
  • Arrow. It helps the technician to control the depth of the development, as well as moving the ripping device. Due to the winch that is included in its basis, is lifting and lowering of the boom.
  • Electricity, water equipment. Has a supporting role in cooling, cleaning and sealing of the pump parts.

As you can see from the description, Dredger for sand mining, a photo that clearly demonstrates a complicated structure of the mechanism is a complex interrelated systems, the interactions of which greatly facilitates the work and simplifies the obtaining of material.

Features available

The Dredgers in the operation must have certain characteristics that allow you to operate as efficiently as possible. For example, the installation and dismantling of dredger should be short and simple. For quickly moving the machine must have a floating base that can be quickly removed if necessary.

ratio prosor dredge in sand mining

When choosing equipment it is necessary to pay attention to the ratio prosor dredger during extraction of sand, type of soil, method of production and possible mechanism. The main feature of the dredger is its performance. This device, which combines a variety of functions. The well-coordinated work functions will yield the maximum performance.

Classification of dredgers

These mechanisms are classified by the method of loading and transporting:

  • A suction Dredger – loading and movingproduced by pulp.
  • Scalabrine – used for loosening slovenij soils of various strengths.
  • Bucket – a kind of excavator machines, moved and immersed in the soil due to the ladle.

According to the method of transportation is divided into:

  • Pump ashore. The coefficient prosor pump ashore dredging by sand mining – an important characteristic that affects the performance of the dredger. Transportation is using pulpwood afloat.
  • Salandy. Transportation using barges – specialized courts that load the soil into the hold and transported him to the port.
  • Languaculture. Used to move soil long tray, which sends it on the shore or on a cargo ship.
  • Samocvetniy. As the name suggests, the dredger loads the soil in his hold and takes him.
  • With the release of pulp jetting effect. Applies if work is carried out in estuaries and marine waters, with a hydraulic.

According to the method of the labor movement:

  • Anchor – propelled by built-in anchors.
  • Self-Propelled – the movement due to the built in engine.
  • Pile – moving on stilts.
  • Pile-anchor – they are used as anchors, and piles.

Working method are divided:

  • Trench – a dredger during extraction of sand forms a trench, moving along the plot.
  • Papilioninae – a dredger in the development of the plot moves across it.
