Can Stone Powder Replace Sand?

Are you familiar with stone powder washing sand? Many friends consult stone powder sand washing equipment. The reason behind it is to use stone powder sand washing instead of river sand. Can the washed stone powder replace the sand? What equipment is used for stone powder sand washing? Here we will give you an answer.

Can stone powder replace sand?

As common natural sand, river sand has an unshakable position in construction and decoration. The stone powder sand is the sand separated as the stone powder after cleaning and screening, and the stone powder is the powder residue left in the crushing and processing of various ores! Whether the stone powder sand concrete is qualified, whether the poured buildings are qualified, and whether there are quality problems and potential safety hazards need to be tested by relevant quality inspection departments.

However, the construction quality is very important. Replacing river sand with stone powder sand must be suspected of shoddy and inappropriate! Although the hardness of stone powder sand is OK, there are some characteristics of river sand, stone powder sand does not. After all, river sand is washed by the river for a long time, and stone powder sand is made manually and mechanically.

The demand for replacing sand with stone powder comes from the shortage of natural river sand resources and the soaring price. So can stone powder replace the sand?

Stone powder can not completely replace river sand but can be replaced within a certain range. Stone powder refers to particles with particle size less than 0.075mm in manufactured sand. The stone powder is the general name of stone powder. There are many kinds of stones. There are many kinds according to mineral composition, not necessarily calcium carbonate. Calcium carbonate is limestone, only one kind of stone powder, and talc powder is also used to make putty. And quartz powder is used to make glass. There are also many mineral rocks that can be ground into powder. The interior of stone powder mostly contains fine particles. After washing with water washing stone powder equipment, high-quality sand can be produced. It is widely used in many fields such as road construction, water conservancy, construction, and concrete mixing plant. The raw material reserve is large, the operation cost is lower than that of machine-made sand, and the profit is very considerable. The stone powder sand-making project has been mature and widely carried out in many places. There are also many users’ doubts that stone powder can not replace sand in some cases. If it is necessary to replace sand, it is necessary to screen and clean the stone powder, control the content of stone powder within a reasonable range according to different end uses, and produce sand of different specifications. Machine-made sand for highway cement concrete has clear technical requirements for stone powder content. If it wants to be used in concrete, it needs to meet relevant technical standards.

What equipment is used for stone powder sand washing?

Because the stone powder contains a lot of dust, soil, and other sundries, it needs to be screened and cleaned before it can be used. So what is the process of stone powder sand washing? What equipment is better for stone powder sand washing?

 

The process flow of stone powder sand washing is as follows

The stone powder is screened by a vibrating screen, and the large materials are screened out, and then the sand conforming to the particle size is sent to the sand washing machine for cleaning through conveying equipment. In the whole process, we need screening equipment, conveying equipment, a sand washing machine, and sewage treatment equipment. Among them, sand washing machine affects the quality of sand.

 

What kind of sand washer do you use?

At present, there are two types of washing stone powder machines and equipment commonly used in the market: Wheel Sand Washing Machine and Spiral Sand Washing Machine. A good washing stone powder machine and equipment should not only process and clean up, but also have a strong sand recovery rate, which can control the mud content of stone powder within a certain range, so that it can be better applied in various fields. Therefore, we should study the selection of sand washing machines.

Spiral Sand Washing Machine

Capacity: 70TPH-350TPH
Feeding Size: ≤10 mm
Water Consumption: 9-280m³/h
Suitable for: Pebble, Granite, Quartz, Limestone, and more.
Spiral Sand Washer is also called a screw sand washer. It can wash and separate the soil and other impurities in sand and gravel aggregate, commonly used in open-pit mining wash plants, artificial stone production lines. Single screw, double screws; small sand washing machine, mobile wash plant (portable wash plant), large scale screw wash plant; coarse sand, fine sand.

The spiral washer is a large piece of equipment for black and non-ferrous metallurgy mines, iron and steel, metallurgy, chemical industry, and building materials to wash ores and stones. The washing machine has great processing capacity, which is an ideal equipment to meet the requirements of large productivity for the cleanliness of ores and stones. Washing first can avoid the crusher and screen machine blocking, In the raw materials, such as soluble or harmful ingredients, should also be washed. The washing machine is widely used in mines, coal, smelting, and other industries.
