Production line and factory setup overview
A small/medium stone-processing line converting sound quarry marble blocks into calibrated rough slabs through block receiving and geological defect inspection, yard handling, block squaring where required, trolley loading, multi-blade gang-saw cutting or selected multi-wire cutting, slurry-water circulation, slab unloading and washing, thickness inspection, slab racking and dispatch to polishing. It does not polish finished slabs.
Recommended lowest-entry line configuration For a credible Afghan entry plant, contract one block-size envelope and one slab thickness. Screen one 30-blade marble gang saw with block trolley, overhead or gantry crane sized for the heaviest block, slab-handling clamps, blade-tensioning and dressing tools, water pumps, two-stage settling pits and filter press or equivalent closed-loop solids management. Confirm foundation dynamics and local blade/segment service before purchase.
Production process and implementation sequence
- Block receiving, weighing and defect mapping
- Yard storage and safe crane handling
- Optional block squaring and base preparation
- Trolley loading, alignment and restraint
- Controlled gang-saw cutting with water
- Slab unloading, separation and washing
- Thickness, flatness, cracks and yield inspection
- Rack storage and transfer to polishing or sale
Products, capacity and market fit
- Afghan marble can retain substantially more value when exported or sold as accurately cut slabs rather than irregular blocks.
- A single stone family and thickness simplify blade settings, yield analysis and buyer approval.
- Closed-loop water and slurry recovery reduce freshwater demand and uncontrolled dust/sludge disposal.
- Block quality, cracks and handling discipline influence saleable yield more than headline cutting speed.
- Rough-cut marble slabs - Buyer-approved stone variety, nominal thickness, tolerance, flatness, crack and surface limits - Local polishing plants and regional slab buyers
- Cut-to-order rough slabs - Separate block plan and thickness schedule with yield agreement - Fabricators with confirmed project dimensions
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
| Block yard and gantry/overhead crane | Receives and safely handles quarry blocks | Rated above the heaviest contracted block |
| Block trolley and alignment system | Positions and restrains block during sawing | Matched to saw chamber |
| Thirty-blade marble gang saw | Cuts one block into parallel rough slabs | Stone-specific blade and stroke |
| Blade tensioning, dressing and workshop tools | Maintains straight accurate cutting | Local service capability |
| Slab clamps, racks and transfer trolley | Prevents breakage during unloading | Non-marking contact surfaces |
| Water pumps and spray system | Cools cutting zone and transports fines | Duty/standby pump design |
| Settling pits and filter press | Recovers water and forms manageable sludge cake | Closed-loop process target |
| Stone inspection and thickness tools | Maps defects and releases slabs | Buyer tolerance plan |
Raw materials, utilities and factory requirements
- Sound quarry marble blocks by variety, dimensions and mapped defect class
- Gang-saw blades, diamond segments or specified abrasives
- Clean makeup water and approved process consumables
- Slab separators, rack protectors, labels and critical pump/saw spares
- Industrial three-phase power, transformer and saw motor-starting study
- Engineered reinforced foundation isolated for saw vibration
- Rated block and slab lifting systems with certified operators
- Closed-loop cutting-water, settling and filter-press system
- Safe slurry-cake storage and licensed reuse or disposal route
Indicative low-entry investment and implementation plan
