3 Steps For Stone Crushers Crush Stone To Sand

Many different types of stones are spread over the mountains in nature, some of which are natural sedimentary rocks. With the current widespread production of mechanism sand, what stones are suitable for sandmaking? What stone crusher is suitable for sand-making? Let’s take a look together.

Stones for sand making

The mountain has abundant raw materials and resources for making sand from stones.
The stone raw materials for sand making are extensive, such as limestone, granite, river pebbles, etc. The different raw material with various stress performance and application of final sand.

  1. Limestone

Limestone is widely distributed in nature and easily obtainable. In sand and gravel production lines, it is the raw material for both sand and gravel, and stone powder is recyclable.

  1. River pebble, cobblestone

River pebble is a widely used aggregate with good texture of sand-making. It is a good alternative to natural sand in strength, granules, and chroma.

  1. Basalt

The sand made of basalt mixed into concrete can reduce the weight of the concrete, but its strength is still good. It has the characteristics of sound and heat insulation. Basalt is a good building aggregate for lightweight concrete in high-rise buildings.

3 Steps For Stone Crushers Crush Stone To Sand

With the advancement of infrastructure, natural sand is no longer meet production needs. So the artificial sand market has emerged, and many people have seen business opportunities in this industry. Artificial sand making is the process of turning stones into sand. So how do we crush stones into sand? It only requires three steps.

Crushing stones into sand includes three steps: crushing, sand making, and sand washing. So what are the specific steps? What is the required equipment? The following will introduce it to you.

        1. Crushing

The first step in breaking stones into sand is to crush them, which breaks them into small pieces. The stone crushers include jaw crushers, cone crushers, and impact crushers. Different crushers can perform coarse, medium, and fine crushing of materials.
The jaw crusher is the primary crusher, with a high crushing rate and large feed particle size. It is suitable for crushing hard stones into small pieces. Cone crushers or impact crushers are the secondary crusher machines. Cone crushers crush harder stones. The impact crusher is suitable for crushing stones with medium hardness or below.

  1. Sand making

The second step in turning stones into sand is sand making, which can process stones into various specifications of sand. Using sand-making equipment to produce coarse sand, medium sand, fine sand, ultra-fine sand, etc. Optional equipment includes an HVI sand-making machine, VSI sand-making machine, fine crusher, etc.

The commonly used sand-making equipment includes HVI and VSI sand-making machines. They are suitable for various types of stone sand-making with high production capacity and performance. VSI sand-making machine is suitable for small-scale sand-making plants, with high sand-making efficiency and good shaping effect. HVI sand-making machine has advanced technology, large output, and strong production capacity.

  1. Sand washing and screening

The third step in turning stones into sand is to wash the sand, which improves the cleanliness of the sand. After crushing and sand-making, the stone-crushing process is completed. If the sand contains too much soil or other impurities, the sand will go to a sand-washing machine for clay cleaning. The commonly used equipment for sand washing is a bucket-wheel sand washing machine and a spiral sand washing machine.

The price of the bucket-wheel sand washing machine is relatively cheap. The investment cost is low, the cost-effectiveness is high, and the requirements for materials during the sand washing process are relatively low. The spiral sand washing machine has the advantages of a simple structure, good sealing structure, low power consumption, and high cleaning efficiency. It meets high standards and requirements with a long service life.

Solutions for a complete sand making plant

The sand making plant is consist of multiple pieces of equipment and cooperate to complete the stone sand production operation. So the vibrating feeding machine, vibrating screen, and belt conveyor support the entire stone sand production line. It mainly consist of a reasonable combination of crushing and sand-making systems. According to the different hardness of stones, the following are common configurations for the complete production line design of making stones into the sand.

  1. Facing stones with high hardness (river pebbles, granite): Jaw crusher+cone crusher+vertical shaft sand-making machine (VSI or HVI)

The jaw crusher+cone crusher is suitable for processing high-hardness stones. After the medium and fine crushing, the material enters an impact sand-making machine for machine-made sand. The cone crusher has high wear and compression resistance for hard stones, and the hydraulic environmental protection device will prevent machine shutdown in case of machine failure, providing dual protection, thus achieving the effect of crushing hard stones.

  1. Facing soft stones (limestone) with a crushing machine+impact crusher+ VSI sand making machine

Jaw crusher+ impact crusher is suitable for rough and fine crushing processing of soft stones. Impact crusher mainly relies on the impact plate and hammer to crush the material into small gravels under the impact force. Soft stones will reduce the wear on the rotor, so it is more suitable for crushing soft rocks. The crushed stones enter the VSI sand-making machine for the sand-making process.
