CRS2750 Sand-Making Machine Successfully Commissioned in Shandong

At a chemical raw material processing park in Shandong, a CRS2750 sand-making machine supplied by Shandong is now operating with high stability and efficiency. Integrating sand and powder production, this equipment plays a pivotal role in preparing high-purity quartz sand for glass manufacturing, becoming a standout solution in the field of mineral grinding.

The raw material processed on site is quartz ore with a hardness below Mohs 7 and moisture content under 6%. The client set stringent requirements on output capacity, fineness control, and environmental compliance. The selected CRS2750 sand-making machine, built upon an optimized Raymond mill structure, features compact design, intelligent control, and excellent adaptability.

This model delivers dual finished products simultaneously:

• Quartz powder with fineness of 80–400 mesh
• Manufactured sand with granularity of 20–120 mesh

This greatly improves material utilization and satisfies diverse product specifications in the production of high-purity glass raw materials.

From delivery to commissioning, the installation took only 5 days, demonstrating excellent ease of setup. The overall machine dimensions are 17000 × 11000 × 15000 mm, with a maximum feed size of ≤35 mm, making it compatible with a wide range of raw ore sizes.

In operation, the machine consistently produces around 65 tons per hour, a 1.5–1.8× increase in output compared to traditional Raymond mills. This dual-output capability is achieved without increasing energy consumption, dramatically reducing energy cost per ton.
