How to Choose River Sand Dryer-Australia Customer Case Attached

Author : Jordan Last Updated : Sep 26, 2019

River sand is also known as yellow sand. It is caused by the repeated impact of large stones on the force of water. Because of the complicated cost of rock, the cost of sand is complicated.

The sand particles are smooth and clean which is not corrosive to buildings. Rivers and sand resources are abundant in countries and regions with more rivers.

Some users didn’t know much about the river sand dryer at the beginning. They will ask why to use a river sand dryer to dry the sand? When the sand is just picked up, it will contain a lot of water. If it can keep up with sales, the seller can just air it a bit. If the sales volume is large, it is impossible to dry it by nature.

Drying and subdividing the sand through the dryer can increase the output with high efficiency, making sand sold more widely.

The usage of river sand

According to the different classification of river sand, its use is different.

1. River sand classification

Specifications: Sand can be divided into fine, medium and coarse sand. The sand has a diameter of 0.25-0.35 mm for fine sand, a diameter of 0.35-.05 mm for medium sand, and greater than 0.5 mm for coarse sand.

Variety of river sand

Variety of river sand

Divided by mesh: Building sand, drying river sand, natural river sand, river sand 4-8 mesh, river sand 8-16 mesh, river sand 10-20 mesh, river sand 20-40 mesh, river sand 40-70 mesh, river sand 50-100 mesh.

Drying river sand means that fish it out from the river, process it, dry it, evenly divide it, pack it, and then sell it. Mainly used in construction and cement products, it can also be used for fire fighting, interior decoration, engineering construction.

Drying sand can be used in building insulation mortar, casting, sewage treatment, an artificial beach and other industries, also can be used in the manufacture of glass, refractory materials, smelting ferrosilicon, smelting solvents, ceramics, abrasive materials, etc.

2. River sand specific use

The mesh river sand is mainly used for concrete with a strength grade greater than C30~C60 and for hydraulic concrete with anti-freezing, impermeability or other requirements.

River sand plays an important role in construction engineering: River sand, stone and cement must be added to the concrete used for paving; the laying of floor tiles, wall tiles and base treatment in the decoration of houses is inseparable from river sand, which is generally recommended to use medium river sand; the mortar used for masonry bricks is synthesized by river sand and cement.

Sand is an essential material in cement mortar. If there is no sand in the cement mortar, the solidification strength of the cement mortar is almost zero.

Types of river sand dryer

The sand dryer completely solves the problem of drying sand, and makes great contributions to various industries such as construction and environmental protection. The economic efficiency of sand dryers for customers is considerable. More and more people are investing in sand drying projects, which have brought huge profits to them.

The following will introduce three types of sand dryers.

1. Small river sand dryer

Small river sand dryer

Small river sand dryer

Below 10 tons per hour is referred to as a small river sand dryer, that is, 3 tons, 5 tons, 10 tons per hour, and so on. Generally, the heat source selection is determined according to the user area and the actual heat source. The operation cost of the sander is almost the same, so the choice is very flexible.

For quantities below 3 tons per hour, users do not have to choose to dry. They can choose to buy dry sand, or air the sand, for the use of electricity is relatively costly.

2. Medium river sand dryer

Medium river sand dryer

Medium river sand dryer

The medium-sized dryer is popular among users because of its price concessions and simple operation. From the customer’s point of view, the small dryer produces less with lower profit, and the user investment is not cost-effective; while the large dryer covers a large area with large time and labor consumption, and the most important is the high price which can be afforded for some investors, so medium-sized dryers have become their best choice.

3. Large sand river dryer

Large sand river dryer

Large sand river dryer

Large dryer refers to dryers that have a large output and can meet large production lines. For the users, if such a large device can not meet their needs, it will cause a lot of losses. In a highly competitive market environment, delaying the construction period is tantamount to delaying the survival and development of the company.

In the following, we recommend the most popular large dryer models of Fote Heavy Machinery, the large-scale manufacturers, have exported our products more than 200 countries, and the quality is guaranteed.

Under normal conditions, the length of the dryer is 10 times as large as the diameter. However, it is not strictly by this standard, and the length can be adjusted according to the needs of the customer’s project. The largest transaction is between 1.2-3 meters in diameter, and the value of the majority is between $42000 and $280000.

Factors affecting sand dryer selection

The huge demand in the market attracts an increasing of sand dryer manufacturers, and the price is quite uneven. So how do users choose river sand dryers, what are the factors to consider when choosing them? Let’s talk about the factors that affect river sand dryer selection.

Factors affecting sand dryer selection

Factors affecting sand dryer selection

  • 1 High applicability: Drying equipment is first and foremost necessary to be applied to specific materials, and the demand for the drying foundation of the materials is satisfactory, including the ability to dispose of materials well (feeding, transporting, fluidizing, dispersing, heat transferring, discharging, etc.), and can meet the basic needs of disposal volume, dewatering amount, product quality and so on.
  • 2 High drying rate: From the drying rate, when the convection is dry, the material is highly dispersed in the hot air, and the critical moisture content is low with fast speed. Under the same convention condition, the drying method is different and the critical moisture content is not the same. Therefore, the drying rate is also different.
  • 3 Low energy consumption: Different drying method has different energy consumption target. Usually, the conduction of drying thermal power is theoretically up to 100%, convective drying only about 70%.
  • 4 Saving capital: the same function of the drying equipment, sometimes the price is very different, the equipment with a fair price is the better one.
  • 5 Low investment cost: Equipment depreciation, energy consumption, labor costs, maintenance costs, spare parts costs and other operating costs should be as low as possible.
  • 6 High-quality dryer: Prioritize the selection of drying equipment with a simple layout, sufficient supply of spare parts, high reliability and long service life.
  • 7 Environmental protection: It should be in line with environmental protection needs with good working conditions and high security.
  • 8 Drying experiment: It is better to do a dry test for materials before the selection, which is often helpful in proper selection.
  • 9 Reliable manufacturer: Users should not completely rely on the experience over pay more attention to the absorption of new technology. It is helpful to listen to the recommendations of the dryer manufacturers.

Customer Case - River sand dryer in Australia

Australia has long been known as the “country in the mine train” and has a history of more than 200 years of mineral development. Australian mineral resources are extremely rich in both varieties and reserves, and these minerals are high in height, shallow in burial and easy to mine, and some ore is barely exposed on the surface.

In addition, Australia’s sandstone minerals are extremely rich. Many parts of the Arab world, including Dubai, are importing a large amount of sand from Australia - Burj Khalifa in Dubai, the tallest building in the world containing Australian sand.
