This short double blade mining machine reference names granite, marble and slate as suitable quarry materials. The source contains no model, blade arrangement or site result, so the page focuses on the decisions that change with each stone.
Granite duty
Granite selection needs the actual variety, block dimensions, cutting depth, blade core and segment set. A hard-stone setup cannot be inferred from the machine silhouette or from the broad material list in the old description.
Marble and slate duty
Marble and slate have different structures and saleable-face requirements. The quarry plan should consider bedding, veining, block support and the intended cut direction. They should not share a generic feed setting or consumable recommendation simply because the same machine family can be used.
Evidence missing from the recording page
No quarry, machine model, blade sizes, motor, rail spacing, water or output is recorded. The video may help identify the double blade layout, but any unreadable specification remains unknown.
A useful acceptance sheet would name one stone and machine configuration, then record travel behavior, finished geometry and wear by blade position. That makes the page specific without inventing facts the source never supplied.
