Technological process of sandstone crushing line

The raw materials enter the European PEW 1100 hydraulic jaw crusher for rough crushing with ZSW490 * 130 feeder, and then enter the CSB240 cone crusher for second crushing, and the material after crushing will enter the 2Y2460 vibrating screen for screening. علاوه بر این, the recycled material enters the secondary crusher, the materials less than 150mm enter the HPT300 for third crushing, and more than 40mm will continue to enter the HPT300 for repeated crushing, less than 40mm will also enter the VSI5X-1145 impact crusher. The finished size reaches 0-5mm, 5-10میلی متر, 10-20میلی متر, 20 – 31.5میلی متر, and the current sandstone crushing production line has high productivity and good grain shape.

Advantage of sandstone crushing line

1. Adopt the latest type of European hydraulic jaw crusher, V type crushing cavity structure with large breast, strong adhesive force and large capacity; Adjust the outlet gap size with a wedge-shaped hydraulic system, saving debugging time. بعلاوه, adopting centralized lubrication, it is very convenient for maintenance.
2. The third crushing unit adopts a multi-cylinder hydraulic cone crusher. It combines higher speed and stroke, greatly improving the rated power and throughput of the HPT crusher, as well as the crushing ratio and production efficiency. The special crushing cavity design and rotating speed significantly improve the fine-grained material proportion and product cubic content, and fully reduce the occurrence of needle-shaped materials. The multi-cylinder hydraulic cone crusher uses a liquid lubrication system, allowing it to operate without manual refilling per shift, saving labor costs. بعلاوه, it is very convenient for equipment maintenance, reducing production and operating costs.
3. The production line adopts three-stage crushing, which achieves the maximum optimization of the crushing degree at all crushing levels. After the second crushing, the secondary screening is carried out, and then the material is directly processed. This not only reduces the crushing pressure of the tertiary cone crusher, but also the entire production line can achieve the maximum optimization of production capacity.

What is the sandstone sand making process?

The detailed sandstone sand making process and technology usually includes these main steps and methods:

1. Raw Material Preparation

Sandstone is first taken out from quarries. Large blocks are fed into the crushing system—usually starting with a jaw crusher—to break them into smaller pieces for further processing.

2. Crushing Stages

Primary crushing with a jaw crusher breaks sandstone blocks into manageable pieces. Secondary crushing, often done with an impact or cone crusher, further reduces the size to make sand-sized particles.

3. Screening and Classification

• Vibrating screens separate the crushed material by size.
• Oversized pieces are returned for further crushing, while properly sized material proceeds to sand production.

4. Sand Making and Shaping

Special sand making machines or vertical shaft impact crusher (هر کس) further grind and shape the particles to get the desired sand shape, size range, and surface texture. This step makes the sand more uniform and improves its performance for different uses.

5. Washing and Purification

The crushed and shaped sand is washed to remove impurities such as clay, silt, or other unwanted materials. Cleaning methods may include scrubbing, separating by density (cycloning), or using gravity to improve purity.

6. Dewatering and Drying

After washing, the sand is dried using vibrating screens, hydrocyclones, or belt presses to remove excess water. Drying machines might be used if dry sand is needed for the final product.

7. Quality Control and Stockpiling

The processed sand is tested for size, شکل, cleanliness, and physical qualities. Final sorting ensures the sand meets industry standards. Good-quality sand is stored and prepared for delivery or further use.
