Basalt sand-making machines are commonly referred to as double-roll sand-making machines or double-roll crushers. They efficiently crush basalt through the relative rotation of two rolls, utilizing compression and shear forces. To enhance performance and operability, hydraulic double-roll sand makers and hydraulic double-roll crushers are also available on the market. These units incorporate hydraulic adjustment systems that precisely control the gap between the two rolls, flexibly adapting to varying particle size requirements. They also offer outstanding wear resistance and low maintenance costs, making them an ideal choice for the basalt processing industry.

1.What are the models of basalt sand making machines?

They can be categorized into large, medium, and small sizes based on model specifications.

2PGT400×250, 2PGT400×400, 2PGT610×400: With an hourly output of approximately 2-20 tons, these are small spring-loaded pebble sand making machines suitable for investment by small to medium-sized sand plants.

2PGT750×500, 2PGT800×600, with an hourly output of 10-50 tons, are medium-sized spring pebble sand makers. This model is suitable for new sand plants with relatively low investment costs.

2PGY750×500, 2PGY800×600, 2PGY800×800, 2PGY1000×800, with an hourly output of 20-80 tons, are medium-sized hydraulic pebble sand makers. Hydraulic models offer greater intelligence, higher output, and more cost-effective operation.

2PGY1000×1000, 2PGY1200×1200, 2PGY1500×1000, 2PGY1800×1000, 2PGY2000×1000, with hourly output of 80-400 tons, belong to the large flagship series of CNC pebble sand makers. Suitable for medium to large sand plants, they feature one-button start/stop for convenient and efficient operation.

2.Working Principle

The basalt sand-making machine operates on the principle of compression crushing. Its core consists of a pair of high-strength, wear-resistant counter-rotating rollers. During operation, raw basalt material enters the crushing chamber through the feed inlet and is subjected to intense compression by the two high-speed rotating rollers. The crushing force and output particle size are controlled by adjusting the distance between the rollers. Under the combined squeezing and shearing forces of the two rollers, the hard basalt is progressively crushed and refined into sand and gravel products featuring uniform particle shape and well-graded size distribution.
