From Low Output to High Capacity – A Perlite Sand Making Upgrade

Project Background

A non-metallic mineral processing enterprise, established in 2010, specializes in perlite ore crushing, grading, and deep processing. Its products are widely used in building insulation, agricultural improvement, industrial casting, and other fields. With growing market demand for perlite manufactured sand, the client planned to expand production capacity and improve product quality.

Problems with the Original Equipment

The client previously used an old hammer crusher, which presented several issues during operation:

Frequent wear parts replacement: The hammers wore out extremely fast, requiring replacement every 1-2 months on average, resulting in high maintenance costs and prolonged production downtime.

Severe over-crushing: The high-speed impact crushing action of the hammer crusher produced excessive fine powder from the perlite, reducing the yield rate and wasting resources.

High dust pollution: Poor equipment sealing led to dust-filled workshops, creating environmental compliance pressure and poor working conditions for employees.

Solution and Equipment Selection

Based on the material characteristics of perlite (medium hardness, brittle, dust-prone) and the client’s capacity requirements, Huashengming recommended the roll crusher (perlite sand making machine) .

This equipment uses a double-roll counter-rotating compression crushing principle. Material fed between the two rolls is subjected to uniform, stable compressive force for crushing. Compared to the high-speed impact action of a hammer crusher, the roll crusher offers the following core advantages:

Long-lasting wear parts: The roll shells are made of high-chromium manganese steel wear-resistant material, with an average service life of over 2 years, significantly reducing maintenance costs.

Precise and adjustable output size: The hydraulic system allows easy adjustment of the gap between the two rolls, with output size adjustable from 1-3mm to meet various specification requirements.

Low over-crushing rate, high yield: The compression crushing method avoids excessive fines, producing sand with well-graded, cubical particles.

Low dust, environmentally friendly: The equipment runs smoothly with good sealing, effectively improving the working environment.

The equipment accepts feed size up to 80mm, with capacities ranging from 5 to 450 tons per hour across more than 20 models, allowing flexible selection based on customer needs.

Operational Results and Customer Feedback

After installation and commissioning, the new equipment officially went into production, with all indicators meeting expectations:

Stable capacity: Actual processing capacity met the client’s order requirements, with smooth production line operation.

Uniform output size: The hydraulic system automatically adjusted the roll gap, producing well-graded finished sand with stable quality.

Significantly reduced maintenance costs: The long service life of the roll shells eliminated the need for frequent shutdowns for wear parts replacement, improving equipment uptime.

Environmental compliance: Dust emissions were significantly reduced, with notable improvement in workshop conditions.

The client’s project manager commented: “Huashengming’s roll crusher is easy to operate and produces stable output. The roll shells are durable, so we don’t have to change hammers constantly like before. Production is up, and costs are down.”

Conclusion

The successful application of this perlite sand making project demonstrates that for medium-hardness, brittle non-metallic minerals like perlite, Huashengming’s roll crusher offers significant advantages in output precision, yield rate, operational stability, and maintenance costs.
