Granite Quarry Equipment List: The Complete Machine Fleet for 1,000 m³/Month Block Production
If you are budgeting a granite quarry, the first serious question is not which machine to buy — it is what the complete fleet looks like, and how many of each machine a real production target demands. This article publishes Set Makina’s reference equipment list for a granite quarry producing 1,000 m³ of blocks per…

Drilling or Cutting for Granite Extraction? A Cost Comparison per Cubic Metre
In marble quarrying, the question was settled decades ago: diamond wire cutting is the primary extraction method almost everywhere. In granite, the question is still open on every new project — and getting it wrong can double or triple the production cost of every cubic metre. Drilling-based granite extraction and diamond wire cutting are both…

Rail-Type vs. Bridge-Type Wire Saw: Which Machine Fits Quarry Extraction
“Wire saw” is not one machine. A rail-type wire saw and a bridge-type wire saw share the same cutting principle — a diamond wire loop running around a drive flywheel — but they are built for different jobs, and confusing them is a costly specification error. We still see purchase lists and public tenders that…

Diamond Wire Cutting Speed for Granite: Why Variable Speed Control Matters
Diamond wire cutting speed is the single most misunderstood parameter in granite quarrying. Marble cuts well at a high, stable peripheral speed in the 40–50 m/s range, so many buyers — and even some tender specifications — assume granite works the same way. It does not. Granite requires a variable peripheral speed, typically between 25…

Vane vs. Axial Piston Pneumatic Motors: Which Is Right for Your Application?
Choosing between a vane type pneumatic motor and an axial piston pneumatic motor is one of the most consequential decisions in industrial drive system design. Both convert compressed air into rotary mechanical energy — but they do it through fundamentally different mechanisms, and each excels in a distinct set of applications. In this guide, we…

Reducing Cost per Meter Drilled: A Practical Guide for Quarry Managers
Cost per meter drilled is the single most important productivity metric in quarry and mining operations — yet most operations never calculate it accurately. Instead, managers focus on daily advance rates or shift output, while the hidden costs of bit wear, compressor energy, unplanned downtime, and rod losses quietly erode their margins. In this guide,…

ATEX Pneumatic Motors for Hazardous Environments: Underground, Surface, and Normal Use Explained
When an ATEX pneumatic motor is required for a hazardous environment, the wrong certification choice carries serious legal, safety, and financial consequences. Set Makina manufactures both vane type and axial piston pneumatic motors in three distinct certification variants — Underground ATEX, Surface ATEX, and Normal Use — and each must be specified correctly at the…

Top 5 Questions to Ask Before Buying a Hydraulic Crawler Drill
A hydraulic crawler drill is one of the most significant capital equipment purchases a quarry or construction operation makes. Get it right and it pays back steadily for ten years or more. Get it wrong and the mismatch costs you in productivity, consumables, and downtime from the first week. In this guide, we walk through…

DTH Hammer vs. Top Hammer Drilling: Which Is Right for Your Operation?
When evaluating rock drilling technology for your quarry or mining operation, the choice between DTH hammer drilling and top hammer drilling is one of the most consequential decisions you will make. Both methods break rock effectively — but they do it differently, they excel in different conditions, and they carry very different cost profiles. In…
