Copper Ore Gyratory Crusher for Slurry Preparation

Copper Ore Gyratory Crusher for Slurry Preparation – Product Overview

In the copper ore beneficiation process, the feed capacity of the primary crushing equipment influences the upper limit of the entire production line. The feed opening size of the Copper ore gyratory crusher for slurry preparation needs to match the maximum blasted lump size, while the reduction ratio directly affects the feed load of the SAG mill. If either of these parameters is incorrectly selected, the subsequent grinding efficiency will be continuously impacted.

This equipment reduces run-of-mine ore with a diameter exceeding 1.5 meters down to 150–300 mm, providing qualified feed for slurry preparation. Major copper mines worldwide, such as Escondida in Chile, Highland Valley in Canada, and Udokan in Russia, all use this equipment as their primary crushing solution.

Core Advantages of Copper Ore Gyratory Crusher for Slurry Preparation

When large-scale copper mines select primary crushers, the core considerations focus on three aspects: throughput per unit time, continuous operation capability, and product size stability. The Copper ore gyratory crusher for slurry preparation performs strongly in all three dimensions.

High throughput: The FLSmidth TSUV-type unit can achieve throughput exceeding 12,000 tons per hour, with an upper limit of approximately 15,000 tons per hour. The Metso Superior MKIII series, launched in 2018, has sold over 50 units worldwide and is relatively widely applied in copper concentrators.

Continuous operation capability: This model employs a gyratory motion to achieve continuous crushing and can meet the demands of long-duration production in mining operations. Highland Valley Copper in Canada uses two units in combination with a belt conveyor system, delivering 130,000 tons of run-of-mine ore per day, which validates the equipment's continuous operation capability.

Product size control precision: The hydraulic system allows real-time adjustment of the discharge opening to achieve accurate product size control. At Udokan Copper in Russia, the primary crushing parameters of the installed unit can be monitored and adjusted in real time from the automated operator workstation.

How Does Copper Ore Gyratory Crusher for Slurry Preparation Operate and What Are Its Core Components？

The Copper ore gyratory crusher for slurry preparation features a horizontal shaft driven by an electric motor, which rotates the eccentric assembly and drives the mantle's gyratory motion inside the fixed concave. The mantle gyrated numerous times per minute, compressing the ore continuously until it discharges by gravity – unlike jaw crushers, which rely on intermittent crushing. The hydraulic system adjusts the discharge opening in real time and releases the mantle when an uncrushable object enters.

The equipment has a heavy-duty frame and integral main shaft assembly, with shaft and mantle diameters of 1200–1600 mm. Key components include cast bearings, replaceable alloy liners, and multi-point sensors. The FLSmidth TSUV series features a top-service design for overhead crane maintenance, while the lubrication system integrates heating, cooling, and circulation, with real-time monitoring of oil pressure, bearing temperature, and shaft position.

Technical Parameters of Copper Ore Gyratory Crusher for Slurry Preparation – Full Specifications

The key technical parameters of the Copper ore gyratory crusher for slurry preparation are shown in the table below. Different models correspond to different capacities and feed requirements.

The above parameters are measured under standard conditions of copper ore with compressive strength up to 320 MPa. Actual model selection should be based on daily throughput, maximum feed size, and downstream mill feed requirements.

Global actual operating data: Escondida in Chile operates three units with capacities of 7,420, 9,330, and 5,000 tons per hour respectively. The capacity differences stem from variations in ore type and feed size distribution, meaning that selection must be matched to the specific characteristics of each deposit. Highland Valley Copper in Canada uses two semi-mobile units that deliver 130,000 tons of ore per day. Udokan Copper in Russia operates a unit that processes over 4,000 tons per hour, with all parameters controllable from the operator workstation.

Which Copper Ore Types Can Copper Ore Gyratory Crusher for Slurry Preparation Process？

The Copper ore gyratory crusher for slurry preparation can handle multiple types of copper ores, including porphyry copper, sulfide copper, and oxide copper, with application cases across different copper belts worldwide.

Porphyry copper ore: Porphyry copper is one of the more widely distributed copper ore types globally, characterized by relatively high hardness and strong abrasiveness. Escondida in Chile is a representative porphyry copper deposit and uses this equipment as its primary crushing solution.

Sulfide copper ore: Sulfide copper ore is the main feed for flotation circuits. Codelco's Radomiro Tomic mine in Chile uses a Superior MKIII 60-110 unit.

Oxide copper ore: Oxide copper ore requires crushing to increase leaching contact area. Escondida operates a heap leach pad processing 48,000 tons of oxide ore per day.

Copper Ore Gyratory Crusher for Slurry Preparation vs Jaw Crusher – A Comparative Analysis

The differences between the Copper ore gyratory crusher for slurry preparation and the jaw crusher in copper ore primary crushing lie in capacity, capital cost, and suitable scale. The unit capacity of the former is typically 2-3 times that of a jaw crusher, but the capital investment is 40-60% higher. For small copper mines with daily throughput below 10,000 tons, a jaw crusher is more economical; for large copper mines exceeding 30,000 tons per day, this equipment offers lower overall operating costs.

In actual ore processing performance, production data from Escondida in Chile show that this equipment achieves a stable product P80 of 180-200 mm when processing porphyry copper ore, whereas under the same conditions a jaw crusher typically produces a P80 of 220-250 mm. The wider size distribution from the jaw crusher increases the load on the downstream SAG mill.

Maintenance and Safety Features of Copper Ore Gyratory Crusher for Slurry Preparation

The daily maintenance of this equipment mainly includes liner wear inspection, lubrication system management, and discharge opening calibration. The liners of the Copper ore gyratory crusher for slurry preparation are typically made of manganese steel, with the Mn18Cr2 grade containing 17-19% manganese and 1.5-2.5% chromium.

Field maintenance records from Escondida show that a single liner change on the unit takes 36-48 hours. After switching to the Mn18Cr2 grade, the replacement interval extended from 6,000 hours to 8,200 hours, reducing maintenance downtime by 2-3 times per year and increasing annual production per unit by approximately 150,000-200,000 tons. In terms of safety features, the FLSmidth TSUV series adopts a top-service design, allowing the entire shell and liners to be replaced as a single unit, which helps reduce equipment downtime and lower operational risks.
