Hard material sand making process

1. Feeding and coarse crushing

1. Use a vibrating feeder to evenly feed hard materials into the coarse crushing equipment.

2. Use a jaw crusher for coarse crushing. The jaw crusher is suitable for primary crushing of hard materials. Materials with a feed size of less than 1200mm can be crushed, and the processing range is wide.

2. Medium and fine crushing and screening

1. The coarsely crushed materials are transported by conveying equipment to the medium and fine crushing equipment for further crushing. For hard materials, cone crushers are usually used for secondary crushing.

2. The crushed materials are screened, and the materials that meet the requirements enter the next process, and the materials that do not meet the requirements are sent back to the crusher for re-crushing.

3. Sand making and shaping

1. Use a sand making machine to crush and shape the screened materials. For hard materials, the vertical shaft impact crusher has a better crushing effect, and the processed materials have a more uniform particle size.

2. In order to improve the sand formation rate, control the fineness modulus and stone powder content, the rotor speed of the sand making machine, the feed grading and other parameters can be adjusted.

4. Screening and sand washing

1. Use a vibrating screen to screen the finished sand after sand making, which is usually divided into coarse sand, medium sand and fine sand.

2. In order to obtain clean finished machine-made sand, a sand washing machine can be equipped for sand washing. The commonly used sand washing equipment is a wheel bucket sand washing machine, and the sand particles after washing have good shape and high quality.

5. Auxiliary equipment and dust removal

1. In the sand making process, auxiliary equipment such as belt conveyors and dust removal equipment are also required to ensure the smooth operation of the production line and environmental protection requirements.

2. Dust removal equipment can effectively reduce dust pollution and protect the environment and workers' health.

In summary, the hard material sand making process includes feeding and coarse crushing, medium and fine crushing and screening, sand making and shaping, screening and sand washing, and auxiliary equipment and dust removal.
