This operation page traces the double blade mining machine back to the circular-saw principle used in stone-processing factories. It also records a change in application: from granite mining to wider use across different stone mines.
The source describes the equipment through its operating principle and application history, not through a model sheet or a measured quarry result.
Factory-saw principle in a quarry machine
The old text says the double blade machine is based on the circular saw used in a stone factory. That establishes the cutting concept, but it does not specify blade diameter, spacing, travel system or cutting depth.
From granite to other stone
Granite mining is named as the original application. The article says the machine later became widely used for various types of stone. No named marble, slate or other quarry is attached to that statement, so suitability still has to be confirmed for the actual deposit.
How to read the operation claim
Huada characterizes the machine as safe, efficient and stable and says many stone-mining enterprises choose it. Those are broad supplier claims without a comparison, customer list or acceptance record on this page. The recording may help viewers recognize the operating arrangement, while an equipment decision still needs the stone, bench layout, intended block and offered machine configuration.
