Is it feasible to use construction waste to make sand? What equipment is needed?

Since the price of sand and gravel in many regions soared last year, the price of sand and gravel has been running at a high level. The domestic supply of sand and gravel is in short supply, and the price has hit new highs. Many people have set their sights on machine-made sand. There are many kinds of raw materials for machine-made sand. The production prospects of using construction waste to process it into machine-made sand are broader. Here is an analysis of the feasibility of making sand from construction waste:

It is feasible to use construction waste to make sand. Construction waste contains a large amount of concrete, bricks and other wastes. After proper treatment and processing, it can be made into recycled aggregates for the production of concrete, road construction materials, etc. Using construction waste to make sand can not only reduce environmental pollution, but also save raw materials and reduce production costs. The following are the main equipment required to make construction waste into sand and gravel aggregates:

1. Primary crushing equipment:

First, primary crushing equipment, such as jaw crusher, is needed to crush large pieces of material in construction waste into smaller particles.

2. Secondary crushing equipment:

Next, secondary crushing equipment such as impact crusher or cone crusher can be used to further crush the construction waste particles.

3. Screening equipment:

In order to separate the aggregates from the impurities in the construction waste, screening equipment is needed for screening. Common screening equipment includes vibrating screens, etc.

4. Sand making equipment:

In order to obtain the required particle size and shape of sand and gravel aggregates, sand making equipment is needed to crush and shape the construction waste. Commonly used sand making equipment includes vertical shaft impact crusher, roller sand making machine and rod mill sand making machine.

5. Sand washing equipment:

In order to improve the quality of sand and gravel aggregates, it is necessary to clean the aggregates after crushing and sand making. Commonly used sand washing equipment includes bucket sand washing machine, spiral sand washing machine and vibrating sand washing machine.

6. Screening equipment:

In order to ensure the uniform particle size of sand and gravel aggregates, screening equipment is needed to grade the aggregates after crushing and sand making. Commonly used screening equipment includes vibrating screens, etc.

According to production needs, users can choose appropriate crushing, sand making and sand washing equipment to meet production requirements. In actual production, equipment configuration can also be optimized and production efficiency and product quality can be improved through experiments and other means.
