High-Efficiency Double Blade Granite Quarrying Machine /Stone Mining Cutter

Which country has the largest output of granite for mining in the world?

China is the world’s largest producer of granite for mining. In 2024, China produced approximately 11 million tons of granite building-stone—about 36% of global output.

What is the popular granite mining method in China?

By double blade mining machine for vertical cutting combined with wire saw machine for bottom horizontal cutting.

Why this solution?

Use the advantages of double blade quarrying machine

* High speed --- It can cut est. 15 sqm/hour, while the wire saw cuts about 10 sqm/hour.

* Low consumption --- It cost about USD1.00/sqm, while the wire saw cost USD1.5-2.3/sqm.

Disadvangtages of double blade quarry cutting machine:  It can only make straight and vertical cutting.

So, for bottom horizontal cutting, we use quarry wire saw, which can cut flexibly in any direction.
