Step by step jaw crusher selection for tin ore 35 tph in Bangka Indonesia

Understanding Bangka's tin ore and its crushing challenges
Bangka Island, part of Indonesia's "Tin Belt," has been a global tin producer for decades. The region's alluvial and primary tin deposits contain hard cassiterite-bearing rocks mixed with clay, quartz, and other minerals. Crushing tin ore at 35 tonnes per hour requires a primary jaw crusher that can handle feed sizes up to 400–500 mm while minimising over-grinding, which can affect downstream gravity concentration. Moisture content often ranges from 5–12%, making clay build-up a concern. A step by step jaw crusher selection for tin ore 35 tph in Bangka Indonesia must begin with understanding these site-specific conditions. OCP Mechanical Company, with 40+ years of direct manufacturing experience, offers crushers tailored to tropical, high-humidity environments. Our factory-direct model ensures competitive pricing without quality compromise.

Step 1: Determine feed size and required product
The first step is analysing your feed gradation. Tin ore from Bangka typically arrives with top sizes of 500 mm, but some deposits produce boulders up to 700 mm. For 35 tph throughput, a jaw crusher with a feed opening of 750×1060 mm or 900×1200 mm is generally suitable. The closed side setting (CSS) should produce a 50–80 mm primary product that feeds secondary crushers or grinding mills. OCP's engineers recommend a CSS of 40–60 mm for this application, balancing capacity with fineness. The step by step jaw crusher selection for tin ore 35 tph in Bangka Indonesia also involves evaluating the ore's abrasiveness—quartz content increases wear on jaw plates, so we suggest manganese steel with a higher carbon content for extended life. All technical data are continuously updated; consult our online support for current parameters.

Step 2: Match crusher capacity and motor power
At 35 tph, the crusher must maintain steady output even with variations in feed density and moisture. OCP's jaw crushers in this class are equipped with 75–90 kW motors, delivering enough crushing force to handle hard tin-bearing rocks. The eccentric shaft speed, typically 250–300 RPM, influences throughput and particle shape. For Bangka's conditions, we recommend a lower speed to reduce fines generation while maintaining capacity. Additionally, the crusher should feature a hydraulic adjustment system for quick CSS changes. This step by step jaw crusher selection for tin ore 35 tph in Bangka Indonesia includes verifying that the motor matches your site's power supply (380V/50Hz in Indonesia). OCP provides customised motor options and starter panels. Price information is for reference only; final quotes depend on specific configurations.

Step 3: Consider maintenance, wear parts, and local logistics
Jaw plates and toggle plates are the main wear items. For tin ore with moderate abrasiveness, OCP's standard manganese plates typically last 600–900 crushing hours. We recommend keeping a spare set on-site to minimise downtime. Maintenance accessibility is critical—our crushers feature hydraulic toggle beam adjustments and easy-access discharge openings. For Bangka operations, we also offer optional rubber-lined feed hoppers to reduce noise. Logistics to Bangka ports such as Pangkal Pinang or direct project site delivery are coordinated by OCP. Our step by step jaw crusher selection for tin ore 35 tph in Bangka Indonesia also covers consignment stocking of critical spares, ensuring availability when needed. All performance figures are estimates; actual results may vary with feed characteristics and maintenance.
