How to produce artificial sand

SHANGHAI SHIBANG MACHINERY CO., LTD is one high-tech enterprise, which involves R&D, production, sales and service as well. In the past 20 years, we devote to producing mining equipments, sand making machines and industrial grinding mills, offering expressway, rail way and water conservancy projects the solution of making high grade sand and matched equipments.

Production process of artificial sand

The raw materials are uniformly sent to the crusher by the feeder for crushing. After the crushing process is completed, the materials with qualified particle size are sent to the sand making machine by the belt conveyor for sand making, and the products that meet the specifications are sent to the vibrating screen for screening. The materials that do not meet the particle size requirements of the finished product are returned to the sand making machine for reprocessing from the vibrating screen, forming a closed circuit for multiple cycles. If the cleanliness of the finished product is high and the water resources on site are sufficient, a sand washer can be configured after the sand making process is completed. In areas where water resources are relatively scarce, a sand and gravel separator can be used instead of the sand washer.

In the production of artificial sand, feeders, vibrating screens and belt conveyors are the basic supporting equipment. Regardless of the manufacturer, the models supplied are not much different. Here mainly lies in the choice of crusher and sand making machine. Those with investment experience should be relatively clear. E crushing and cone crushing are crushed using the extrusion principle, which is suitable for joint processing of hard materials. Hammer crushing and counter-impact crushing use the impact principle. Broken, suitable for processing medium hardness materials.

The difference between machine sand and stone debris:

  • 1. Size: The size of the artificial sand conforms to the national building sand standards, with uniform grain size, good grain shape, and reasonable grading. Aggregate term for the aggregate under the sieve of a sieve with a stone chip of 2.36mm or 4.75mm.
  • 2. Shape: The main difference between stone chips and machine sand is that the content of powdery particles and the content of needle-like particles are relatively large, and the compressive strength of stone is also a difference.
  • 3.Stone chips are also called artificial sand, which has a rougher surface than sand, has sharp edges and corners, and contains more stone powder with a particle size of less than 0.16 mm. The type of artificial sand is uniform in size


What is the difference between artificial sand, natural sand and washed sand?

The differences between machine sand, washed sand and natural sand are mainly divided into the following aspects:

  • 1. Formation process
  • Artificial sand is mainly made by sand making machine and other ancillary equipment; washed sand is natural silicon sand washed and graded raw sand for casting; natural sand is formed by the action of natural conditions (mainly rock weathering).

  • 2. Particle shape
  • The finished product of machine-made sand is more regular, and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. Washed sand is mainly flood beach sedimentary sand, and its appearance is gray-white-gray, containing medium fine sand, Coarse sand, coarse sand, gravel layer, gravel layer. Its occurrence is oriented to the river bed, the surface layer is inclined from the river bank to the river bed, and inclined from the upstream to the downstream; rock particles with a natural sand particle size below 5mm.

  • 3. Cleanliness
  • The machine-made sand is clean and free of dirt. Both washed sand and natural sand have a certain amount of mud content, which is not clean enough.


Artificial sand

Artificial sand refers to sand processed by sand making machines and other auxiliary equipment. The finished product is more regular. It can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. Machine-made sand requires professional equipment to produce qualified and applicable sand.

Natural sand is a sand system that is mined from the natural world. It is called natural sand, and is divided into sandy sand and silica sand. Sources include beach sand, lake sand, river sand, sea sand, and mountain sand. Natural sand is a particle core formed by rock or pebble after being washed by wind and rain or water. It has high strength. Washed sand is natural silica sand washed with water.

Graded raw sand with mud content (mass fraction) ≤ 1.0%. River sand is mainly floodplain sedimentary sand, and its appearance is grayish white to grayish yellow, consisting of medium fine sand, medium coarse sand, coarse sand, gravel layer and gravel layer.
