In the mining process, raw materials are extracted from open excavation sites using heavy machinery such as excavators. In some cases, blasting techniques are employed to break up large rocks for easier extraction. Once the raw material is loosened, it is transferred to a basic processing site.

At the processing site, the mining boulders are separated from unwanted dust and debris. This step is crucial to ensure that only clean boulders are processed further. The clean boulders are then loaded and sent for further processing to be reduced into construction aggregates.

The next step in the process involves screening the materials from the initial screen using a vibratory screen. This helps further separate any remaining dust from the material, ensuring that the final product is of high quality. Any waste material that is separated out is then dumped at a designated area.

The retrieved material, now free of dust and debris, is taken for further processing. This process highlights the importance of efficient waste management and the use of advanced screening technologies to produce high-quality construction aggregates.
