Jaw crusher models and parameters for primary crushing of copper ore

For any copper ore processing plant, the primary crushing stage directly determines downstream throughput and energy consumption. Selecting the right jaw crusher models and parameters for primary crushing of copper ore is critical because copper ores often contain hard quartz veins and have a compressive strength of 150-300 MPa. OCP Machinery, with over 40 years of experience in mining equipment, offers a full range of jaw crushers from small PE-250×400 to large PE-1200×1500. Key parameters include feed opening size (e.g., 900×1200mm allows 750mm max feed), discharge opening adjustment range (70-200mm), eccentric shaft speed (200-330 rpm), and motor power (90-200 kW). A proper model ensures that the crusher can handle occasional oversize boulders without stalling. OCP’s engineers use FEA-optimized moving jaw plates to increase crushing force by 15% compared to standard designs. When you evaluate jaw crusher models and parameters for primary crushing of copper ore, also consider the closed side setting (CSS) which affects product size and downstream cone crusher load.

In actual operation, the copper ore is fed by a vibrating feeder into the jaw crusher’s V-shaped chamber. The movable jaw moves periodically against the fixed jaw, compressing and shearing the ore until it falls through the discharge opening. OCP’s deep-chamber design reduces material slip and increases capacity by 10-12%. For a typical Chilean copper mine with 800 t/h requirement, OCP recommended the JC110 model (1100×850mm feed opening, 160 kW motor, CSS 100mm) which achieves a product P80 of 150mm. The jaw crusher models and parameters for primary crushing of copper ore also influence wear parts life – OCP offers Mn18Cr2 jaw plates that last 40% longer than standard Mn13. Our custom capability means we can modify the tooth profile and toggle plate angle to match your ore’s abrasion index. Additionally, OCP’s direct factory pricing eliminates dealer margins, saving you 20-30% compared to imported brands. Environmental compliance is built in: sealed dust hoods with connection for central dust collection, and rubber dampers to reduce vibration transmission.

The technical advantage of OCP’s jaw crushers includes hydraulic CSS adjustment (safe and fast), automatic lubrication system, and overload protection with toggle plate as a safety device. For a recent copper project in Zambia, OCP provided a tailored jaw crusher models and parameters for primary crushing of copper ore that included a JC125 (1200×950mm feed opening, 200 kW motor) and achieved 920 t/h, exceeding design by 15%. Our 40 years of experience helps avoid common mistakes like undersizing the crusher or ignoring the ore’s moisture content. Moreover, our direct sales model offers free on-site commissioning and operator training. Every jaw crusher from OCP comes with a 12-month warranty and lifetime technical support.
