Sand Making MachineFine Crushing

Sand making machine is suitable for soft or medium hard and very hard ore materials with hardness not higher than 320 Pa. Also, we usually call it VSI sand making machine. It has the characteristics of stable and reliable work, easy maintenance, and a high sand production rate. Now, let’s learn some basic information about it.
Sand Making Machine

The specific production capacity is based on the customer’s site configuration and actual production capacity.

Feeding Size: ≤40mm

Production capacity: 70-640T/H

【Product Particle:】

The finished product of the sand making plant has a cubic shape and low flake content, which is especially suitable for stone shaping and producing mechanism sand.

【Applicable Fields:】

A vertical shaft impact crusher is mainly used for crushing and shaping non-metallic ores, construction materials, artificial sand, and various metallurgical slag.

【Processing Materials:】

The materials that can be processed by sand making crusher machine are limestone, river pebble, mountain stone, lapis lazuli, cobblestone, weathered sand, basalt, granite, quartz, gabbro, etc.

What is a sand making machine?

A sand making machine, also known as a vertical shaft impact crusher, is a type of equipment used to crush or shape rocks into sand particles. Its main purpose is to produce well-shaped sand products that can be used as a substitute for natural sand.

Applications of sand making machine

  • Artificial sand making: processing river pebbles, mountain stones (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, stone chips, and other materials.
  • Construction use: construction aggregate, highway road fabric, bedding material, production of asphalt concrete and cement concrete aggregates.
  • Engineering use: engineering field of water conservancy and hydropower, high-grade roads, highways, high-speed railroads, passenger dedicated lines, bridges, airport runways, municipal engineering, high-rise construction of the production of mechanism sand and stone shaping.
  • Mining industry: fine crushing process in the pre-mill section of the mining industry, material crushing in building materials, metallurgy, chemical industry, mining, refractory materials, cement, grinding materials, and other industries.

Production Process Of Sand Processing Plant

The sand making product line follows a systematic process. Here’s a clear and structured breakdown of the steps involved:

  • Stone Crushing: Large stone pieces stored in the silo are fed into the jaw crusher by a vibrating feeder for coarse crushing. The crushed materials are then conveyed by a belt conveyor to a cone crusher or impact crusher for further crushing.
  • Screening: The belt conveyor transports the crushed materials to a vibrating screen for screening. The vibrating screen separates the finished sands (materials above the sieve) from the oversized particles (materials under the sieve).
  • Sand Washing: The finished sands are carried by a belt conveyor to a sand washing machine for washing and removing impurities. After washing, the cleaned sands are sent to the finished product stack with the help of a belt conveyor.
  • Fine Crushing: The oversized particles (materials under the sieve) are conveyed by the belt conveyor to a vertical mobile impact crusher (artificial sand making machine for sale) for fine crushing. The finely crushed stones are then sent back to the vibrating screen for another round of screening.

This process forms a closed loop where the materials go through repeated crushing and screening stages until they meet the desired size and quality requirements. The rock crusher equipment continues until the desired amount of sand is produced. By following this structured sand processing line, sand manufacturing machines efficiently crush, screen, wash, and refine raw materials to produce high-quality sand products. Let’s take a look at a real case.

Types of sand making machine

1. VSI series sand making machine

VSI sand making machine is a common gravel-making machine in the market. VSI sand maker has a deep cavity rotor design with a large passing capacity. Compared with traditional sand making

Maximum feed size:Hard material <45 mm, soft material <50 mm

Capacity (feed at center):40–365 t/h

Capacity (feed at center and sides):80–650 t/h

Motor power:4P 500 kW

2.PCL series sand making machine

PCL sand making machine is the latest equipment with two functions of sand making and shaping. The finished product is uniform, with a beautiful size and better grain shape. It adopts the best design of the material impact angle of the crushing chamber.

Maximum feed size:Hard material <50 mm, soft material <55 mm

Sand shaping capacity:50–498 t/h

Sand making capacity:90–585 t/h

Motor power:2×315 kW

3. Mobile sand making machine

Both PCL and VSI sand making machines can be equipped with mobile crushing stations. The mobile sand making machine can be driven to the site to start sand making and screening work directly. It not only effectively improves work efficiency, but also facilitates user operation.

Production capacity:40-650 t/h

Equipped with machines:Feeder, sand making machine, vibrating screen, conveyor, etc.

It can be composed of tire-type and crawler-type sand making machines to meet the needs of various coarse, medium, and fine sand production plants.

How does a sand making machine work?

Here’s a detailed breakdown of its working mechanism:

Material Intake:

Raw material flows into the vortex crushing cavity from the feed hopper.
This material is typically rock, gravel, or other hard substances suitable for sand production.

High-Speed Rotation and Impact Crushing:

Inside the machine, a high-speed rotating impeller functions as the main crushing component.
As the impeller rotates at high speed, it scatters the material around it in an umbrella-like pattern, effectively crushing it.

Multiple Collisions and Friction:

The scattered materials collide with each other, undergoing further fragmentation.
A vortex flow is created within the material layer between the impeller and the casing, leading to multiple collisions, friction, and additional crushing.

Discharge and Screening:

Crushed material is discharged from the lower discharge hopper, completing the crushing process.
A screening machine is then used to control the particle size of the finished product, ensuring that it meets the desired specifications.
This process allows for efficient and controlled sand production, which is crucial in various construction and industrial applications. The sand making machine’s ability to crush and refine materials quickly and effectively makes it a valuable piece of equipment in the sand and gravel industry.
