Sand Making Machine

MoleDive Vertical Shaft Impact Crusher yields up to 60-1068t/h

MoleDive Sand Making Machine is specialized in crushing river pebbles, rocks (such as limestone, granite, basalt, diabase, and andesite), ore tailings, and stone chips, with a high hourly output of 60-1068 tons, making it the perfect choice for mining companies.
Compared to traditional sand making machines, MoleDive’s sand making machine has a higher rotational speed, robust and reliable sealing, requires minimal maintenance, and offers a higher sand production rate.
This machine is suitable for various engineering applications, including water conservancy and hydropower projects, high-grade highways, expressways, railways, passenger dedicated lines, bridges, airport runways, municipal projects, and high-rise building sand production and stone shaping. It is also used in the mining industry for primary fine crushing processes and is suitable for materials crushing in industries such as construction, metallurgy, chemical engineering, mining, refractories, cement, and abrasives.

FAQ About Sand Making Machine

1. How does a sand making machine work?

  • Feeding: The equipment is supplied with raw materials, usually bigger boulders, stones, or minerals, through a hopper or conveyor belt.
  • Crushing: Rotating parts like rotors or impellers are within the machine. These parts affect the raw materials as they rotate quickly. This impact can be produced by centrifugal force, a combination of centrifugal and gravitational forces, or by flinging the materials into a high-speed impact wall, depending on the kind of machine.
  • Shaping: The raw materials are broken and crushed into smaller pieces by the high-speed impact. The form and size of the produced particles are determined by the particular design of the machine’s internal components and the speed at which they work.
  • Classification: The materials are frequently sent through a classifier or screening device after being crushed. This distinguishes between smaller and bigger particles, such as sand. The sand is gathered and sent to a distribution or storage system.
  • Recirculation: In certain machines, larger particles that don’t fit the specified size specifications can be recycled back into the crushing chamber for additional processing.
  • Final product: High-quality sand or other desirable grain sizes that may be utilized in a variety of industrial and construction applications are the end result.
Depending on its design and kind, such as vertical shaft impactors (VSI) or horizontal shaft impactors (HSI), a sand producing machine’s precise functioning may change. These devices are frequently employed in the mining sector for the processing of minerals as well as in the manufacturing of produced sand for concrete, asphalt, and other building uses.

2. How is artificial sand made?

  • Artificial sand, commonly referred to as manufactured sand or crushed sand, is made by crushing rocks or stones into sand-sized fragments. Here is how man-made sand is normally created:
  • Extraction and mining: The procedure starts with the extraction of the necessary rocks or stones. These include rocks that are tough and long-lasting, such as granite, basalt, and quartzite. The rocks are mined from natural sources or removed from quarries.
  • Crushing: The mined rocks are transferred to crushing facilities where they are put through various types of crushing equipment, including impact, cone, and jaw crushers. These devices reduce the huge boulders into smaller fragments, ranging in size from pebbles to sand.
  • Screening and washing: The crushed material is usually screened to remove the required sand-sized particles after it has been crushed. The coarser material is separated from the finer particles that match the requirements for artificial sand.
  • Classification: To further purify the sand particles, a classification technique may occasionally be used. This guarantees the sand’s uniformity in size and shape, which is crucial for a variety of applications.
  • Cleaning and washing: Sand may need to be cleaned to get rid of clay, silt, and other contaminants that might degrade its quality, depending on the source material. Getting clean and obtaining the ideal grade both benefit from washing.
  • Storage and distribution: Before being delivered to building sites, concrete manufacturers, or other applications, the finished artificial sand product is kept in silos or stockpiles.

Concrete, asphalt, and mortar are frequently made in the construction sector using artificial sand. It can also be applied in other situations where natural sand is not easily accessible or where particular standards of quality must be satisfied. Artificial sand production strives to mimic the qualities of natural sand while maintaining constant quality and availability.
