Hello, please send us a commercial offer for the following parameters: TECHNICAL SPECIFICATION (TECHNICAL REQUIREMENTS) For the Supply of a Mobile/Stationary Crushing & Screening Plant for Basalt Processing 1. GENERAL INFORMATION Parameter Description Project Name Supply of Crushing & Screening Plant for Basalt Quarry Client Aleksanyan Aharon Marati (Republic of Armenia) End Use Production of construction crushed stone for road and concrete works Material to be Processed Basalt, Doleritic Basalt Compressive Strength 200–300 MPa Moisture Content < 5% Feed Size (Max) 500–700 mm 2. PRODUCTION REQUIREMENTS Parameter Requirement Capacity 50–100 tons per hour (t/h) Annual Output 10,000 tons minimum Operating Schedule Single shift (8 hours/day) 3. OUTPUT FRACTIONS The plant must produce the following finished fractions simultaneously: Fraction Application 0–5 mm Sand / fines (by-product) 5–10 mm Fine crushed stone 10–20 mm Medium crushed stone 20–40 mm Coarse crushed stone Requirement: The crushed stone must have a cubical shape (low flakiness index, preferably < 15%) to meet construction standards (GOST 8267-93, or equivalent). 4. TECHNICAL REQUIREMENTS FOR THE EQUIPMENT 4.1. Crushing Stages For hard and abrasive material (basalt), the following crushing stages are mandatory: Stage Equipment Type Purpose Primary Jaw Crusher Crushing feed material to 0–150 mm Secondary Cone Crusher Medium crushing to 0–50 mm Tertiary (Recommended) Cone Crusher (short head) Final reduction for cubical shape (especially for 5–10 and 10–20 mm fractions) Important: Use of a cone crusher is required for the secondary stage. Rotor crushers (impact crushers) are NOT acceptable for basalt due to high abrasion. 4.2. Screening and Classification Equipment Requirement Vibrating Screen Minimum 3 decks (3 layers of screens) to separate 0–5, 5–10, 10–20, 20–40 mm Return Conveyor To recirculate oversized material (>40 mm) back to the crusher (closed circuit) 4.3. Feeding System Equipment Requirement Hopper / Bunker Minimum capacity: 15 m³ Vibrating Feeder With grizzly bars to bypass fines (0–50 mm) before the primary crusher 4.4. Additional Equipment Equipment Requirement Conveyors Connecting all components; mobile/transportable design preferred Control System PLC-based with centralized control panel Dust Suppression Water spray system at all transfer points Magnetic Separator (Optional) To remove metal contaminants 5. MOBILITY REQUIREMENTS Option Preference Mobile (Wheeled) Preferred – easier to relocate and install without heavy foundations Mobile (Tracked) Acceptable Stationary Considered if mobile cost is significantly lower 6. POWER & ENERGY REQUIREMENTS Parameter Requirement Power Supply 380V, 50 Hz, 3-phase Generator (Optional) Provide price for diesel generator (300–400 kVA) as an option 7. SCOPE OF SUPPLY The supplier must provide: Complete crushing and screening equipment with all components (as per Sections 3–6). Connection cables, pipelines, and accessories for installation. Operation and maintenance manuals (in English or Russian). Spare parts kit (wear parts) for 1 year of operation. Commissioning (Supervision): The supplier shall send a technician to site for installation supervision, commissioning, and operator training (up to 2 weeks). 8. DELIVERY TERMS Parameter Requirement Delivery CIF to Poti, Georgia (Black Sea port) or directly to Yerevan, Armenia Delivery Time Please specify minimum and maximum lead time 9. WARRANTY AND AFTER-SALES SUPPORT Parameter Requirement Warranty Minimum 12 months from commissioning Spare Parts Availability Guaranteed availability for 5 years Technical Support Remote support (by phone/WhatsApp) available 24/7 Service Center Please specify if you have a service center or dealer in Armenia, Russia, or Georgia 10. COMMERCIAL REQUIREMENTS Parameter Requirement Price Please quote in USD Payment Terms Please provide standard proposal Scope of Commercial Offer Please include: - Equipment price (EXW or CIF) - Cost of shipping and insurance - Cost of commissioning / supervision - Price of recommended spare parts kit - Validity of the offer 11. ADDITIONAL INFORMATION REQUESTED Please provide: General layout drawing of the proposed plant with dimensions. Process flow diagram showing material movement. List of main equipment with make/model and technical specifications. Photos or videos of similar plants operating on basalt (if available). Reference list of clients who purchased similar plants for basalt crushing. CONTACT INFORMATION Name Aleksanyan Aharon Marati
