Iso Certified Sand Gravel Mining Vendors
سِرُ: Reduce Fines Generation & Meet Spec: ISO Certified Sand Gravel Mining Vendors for HighVolume Aggregate Operations
1. PAINPOINT driven اوپننگ
Your screening circuit is the bottleneck. Every ton of minus200 material you send to the settling pond represents lost revenue and increased water treatment costs. For commercial sand and gravel operations, the margin between profitability and loss often comes down to two metrics: fines generation rate ۽ product spec compliance.
انهن آپريشنل حقيقتن تي غور ڪريو:
- Fines carryover: Uncontrolled fines (minus200 mesh) in your concrete sand can trigger ASTM C33 rejection, costing you $12–$18 per ton in rehandling and blending.
- Dewatering inefficiency: A standard sand screw can lose 8–12% of your saleable product as overflow slimes, directly reducing your yield.
- Wear costs: Abrasive silica sand can wear through standard carbon steel liners in under 400 ڪم جا ڪلاڪ, driving maintenance budgets 30% above projections.
- Spec volatility: Fluctuating feed from the pit face means your current static screen decks cannot adjust, forcing you to either overgrind or underrecover.
- داخلي سِطح (50-100 ٽي پي ايڇ): $85,000-$120,000 (includes basic VFD, polyurethane پينل, skid mount)
- مڊل رينج (150-250 ٽي پي ايڇ): $145,000–$195,000 (includes dualdeck, spray bar system, پريميئم بيئرنگ)
- HeavyDuty (300-400 ٽي پي ايڇ): $220,000–$290,000 (includes oilbath vibrator, stainless steel wedge wire, remote monitoring interface)
- خودڪار لوڻ وارو نظام: $4,500 (reduces manual greasing frequency to once per month)
- Remote Vibration Monitoring Kit: $6,800 (realtime bearing temperature and stroke data via PLC)
- Custom Feed Box with Wear Liners: $3,200 (for abrasive feeds exceeding 2.5 سليڪا مواد)
- Spare Panel Kit (full deck set): $8,500-$14,000 (ensures 24hour changeout capability)
- معياري وارنٽي: 24 months on vibrator assembly, 12 months on panels
- توسيع ٿيل سروس معاهدو: $8,000/سال (ٽه ماهي معائنو شامل آهن, بيئرنگ جي متبادل تي 15,000 ڪلاڪ, ترجيحي ٽيڪنيڪل سپورٽ)
- ڪميشن ڪرڻ & تربيت: $4,500 (2day onsite setup, آپريٽر جي تربيت, and maintenance protocol documentation)
- LeasetoOwn: 36–60 month terms with 10% بقايا قدر
- سامان جو قرض: Fixed rates from 6.5% اپريل (ڪريڊٽ جي منظوري جي تابع)
- Seasonal Payment Plan: گھٽ پيداوار جي مھينن ۾ گھٽ ادائيگي (November–February)

2. پيداوار جو جائزو
سامان جو قسم: HighFrequency MultiSlope Dewatering Screen (Vibratory Classifier) for Sand & پٿر جي پروسيسنگ
آپريشنل ڪم فلو (5Step Process):
1. فيڊ جو تعارف: ڍل (40–55% solids by weight) enters the feed box via a flanged spigot from your hydrocyclone underflow or sand screw discharge.
2. Initial Stratification: HighGforce vibration (4.5–6.5 G) on the upper deck (polyurethane panel, 0.5mm–1.0mm aperture) separates free water and minus100 mesh fines.
3. MultiSlope Acceleration: Material cascades across three declining slopes (25°, 15°, 5°), increasing bed depth control and reducing water film thickness.
4. Final Dewatering: The lower deck (stainless steel wedge wire, 0.3mm–0.75mm slot) captures saleable sand while allowing clarified water to pass through.
5. خارج ٿيڻ: Product exits at 82–88% solids content (سطح جي نمي <6%), ready for stockpiling or loadout.
ايپليڪيشن جو دائرو: Primary dewatering of concrete sand, ٺڪر واري ريت, and coarse aggregate (up to 3/8inch). حدون: Not designed for heavy claybound feeds (>15% مٽي جو مواد) بغير اسڪريننگ جي; maximum feed temperature 60°C.

8. FAQ
ق: Can this screen handle feed directly from a dredge pump?
اي: ها, provided the feed solids concentration is between 40–55% and the maximum particle size does not exceed 10mm. For higher solids or larger particles, a scalping screen or hydrocyclone is recommended upstream.
ق: What is the typical payback period for replacing a sand screw with this screen?
اي: کان فيلڊ ڊيٽا جي بنياد تي 12 تنصيب, سراسري واپسي جي مدت 14-18 مهينا آهي, driven by increased yield (8-12 سيڪڙو), reduced moisture penalties, ۽ گهٽ سار سنڀال خرچ.
ق: How does this equipment comply with ISO 9001 معيار?
اي: All components are manufactured under ISO 9001:2015 certified processes. The vibrator assembly undergoes 100% runtesting with documented stroke and temperature data. Screen panels are traceable to batch and cure date.
ق: Can the screen be retrofitted into an existing plant layout?
اي: ها. The skidmounted design requires a flat concrete pad (minimum 6inch thickness) and standard electrical connection. The isolation springs reduce structural load transfer, allowing installation on existing mezzanines with load capacity above 150 PSF.
ق: What maintenance is required beyond panel changes?
اي: Weekly inspection of spray bar nozzles (clean if clogged), monthly greasing of vibrator bearings (unless automated system is installed), and quarterly vibration analysis to detect bearing wear. Annual oil change for oilbath models.
ق: Does the VFD allow for remote operation?
اي: ها. The VFD can be integrated with your existing PLC via 420mA signal or Modbus RTU. Remote speed adjustment and fault monitoring are standard capabilities.
ق: What is the lead time for a custom configuration?
اي: Standard models ship in 6–8 weeks. ڪسٽم ٺاھڻ (nonstandard deck size, خاص مواد) require 10–14 weeks. جلدي حڪم (4 هفتا) are available with a 15% expedite fee.
