Can concrete be made into sand? What equipment is good for making sand from concrete?

Yes, concrete can be made into sand, provided it is of a suitable type and in good condition. Concrete sand, also known as aggregate, is a by-product of the concrete production process and can be recycled for use in new concrete mixes. However, it is important to ensure that the concrete is free from contaminants, such as steel reinforcements, wood, and other debris, as these can damage the equipment used for making sand from concrete.

There are several pieces of equipment that can be used to make sand from concrete, including:

1. Concrete crushers: Concrete crushers are designed to break up concrete into smaller pieces, typically by using impact or compression forces. They can be used to process concrete waste, as well as old or damaged concrete structures, to produce sand for reuse in new concrete mixes.

2. Impact crushers: Impact crushers use impact forces to break up concrete into smaller pieces, typically by throwing the concrete against a hard surface or using rotating hammers. They are suitable for processing concrete waste with a low moisture content and are commonly used in quarries and recycling plants.

3. Cone crushers: Cone crushers use a combination of compression and attrition to break up concrete into smaller pieces. They are suitable for processing concrete waste with a high moisture content and are commonly used in aggregate production and recycling plants.

4. Screening equipment: Screening equipment, such as vibrating screens or trommel screens, can be used to separate the sand-sized particles from the larger pieces of concrete. This is typically done after the concrete has been crushed to remove any remaining debris and to ensure that the sand is of a suitable grade for reuse in new concrete mixes.

5. Washing equipment: Washing equipment, such as washing plants or log washers, can be used to remove any remaining debris and impurities from the sand-sized particles. This can help to ensure that the sand is of a suitable quality for reuse in new concrete mixes.

In summary, concrete can be made into sand by using a combination of crushing, screening, and washing equipment. The specific equipment required will depend on the type and condition of the concrete, as well as the desired output size and quality of the sand.
