Product catalog summary

Overview: The MRXT Series Sales Specification Sheets detail the technical specifications of the MRXT Rockbreaker System, designed for mining and quarry applications. The document focuses on the system's components, specifications, and applications, particularly for secondary breaking of oversize material at gyratories and grizzlies.

Specifications:

Operating Weights: Models range from 22,150 lb (10,047 kg) for the MRXT24 to 25,000 lb (11,340 kg) for the MRXT36.
Dimensions: Overall height ranges from 21'1" (6.4 m) to 25' (7.6 m), with working lengths from 25'2" (7.7 m) to 36'4" (11.1 m).
Hydraulic Breaker Operating Weight: Breaker models range from BX40 to BXR85, with weights from 3,830 lb (1,740 kg) to 6,500 lb (2,950 kg).

System Components: Includes boom assembly, hydraulic breaker, breaker tool, joystick controls, control cable, electric hydraulic power pack, and greasing system.

Design Parameters: Designed for endurance in gyratory crusher and grizzly applications, with features to withstand side bending, torsional loading, vibration, and shock loads. Heavy hydraulic cylinders and joint construction ensure durability and extended service life.

Turntable Construction: Features a 330-degree swing, hydraulic drive motor brake, gearbox, and gear-driven slew ring.

Applications: Used for secondary breaking of oversize material at gyratories and grizzlies, with configurations for different site requirements. Proper location and sizing are crucial for effective operation.

Hydraulic Breaker Specifications: Energy classes range from 4,000 ft·lb (5,400 joule) to 8,500 ft·lb (11,524 joule). Operating weights and tool diameters vary by model, with specific flow rates and operating pressures.

Recommendations: Ensure proper sizing and location for optimal performance. Consider material hardness and size when selecting the appropriate breaker model.

Installation Guidelines: Systems are shipped unassembled, including components like the turntable, electric hydraulic power pack, and hydraulic breaker. Installation can be on reinforced concrete or structural steel, with specific guidelines for stability against dynamic forces.

Site Preparation: Reinforced concrete installations require a foundation mounting plate embedded in concrete, with tie rods aligned within 1/8" tolerance. Structural steel installations involve a tower to elevate the turntable, requiring engineering review to meet local codes and conditions.

Force and Moment Diagrams: Provide maximum static loads and moments, with dynamic values estimated at twice the static values. Details on swing torque and load distribution are included for proper system configuration.

Power Pack Specifications: Includes a premium efficiency TEFC electric motor and a high-pressure hydraulic swash plate piston pump, tailored to match boom and breaker size requirements.

Procedures: Installation procedure suggests selecting a power pack site convenient for repair and operator access, avoiding exposure to flying rock, dust, and dirt. The power pack should be placed against a wall with one side and end open for plumbing connections and service access.

Standards and Recommendations: Locate the power pack within a heated enclosure for cold weather applications. Insulate hydraulic lines between the power pack and the valve, which is the customer's responsibility. The power pack is supplied without electrical wiring, allowing for configuration with existing setups or control panels.

Optional Equipment: Includes immersion heaters, electric motor deration for altitude, and various control system enhancements such as secondary joystick controls and radio remote control pendants. Cold weather options include space heaters and heat trace lines for hydraulic components.

Control System: Features a stand-mounted joystick control with dual-axis IQAN proportional joystick controls, a Parker IQAN MD3 control module, and a high/low temperature shutdown feature. Optional control equipment includes secondary portable joystick control pendants and ergonomic suspension seats with armrest-mounted joysticks.

Operator's Cabin: Options include medium and large cabs with heavy gauge steel construction, impact-resistant windows, and polyurethane insulation. Optional equipment includes electric heaters, air conditioning, and explosion-proof window covers.

Control Systems: Offers various control options including manual hydraulic control with four levers, remote electro/hydraulic joystick stands, portable joystick systems, and radio remote control systems. Each system provides independent control of boom functions with features like emergency stop buttons, indicator lights, and power shutdown capabilities.

IQAN™ System: A sophisticated control and monitoring system for hydraulics, allowing user-programmable control and data communication. It simplifies servicing with easy sensor calibration and error logging, enabling remote fault analysis and machine updates.

HVC Option: Includes a high-speed control valve with position feedback, anti-lunge protection, and programmable soft stops. Ensures smooth operation and prevents sudden movements that could damage the equipment.

Auto Grease Options: Includes hydraulic and pneumatic auto lubrication options, ensuring efficient lubrication of the boom and breaker components. These systems are designed for automatic operation and include high-volume refill fittings.

Cab Options: Operator cabs are available in medium and large sizes, constructed with heavy gauge steel and insulated for comfort. They feature safety glass windows and ergonomic seating, with options for additional doors and windows.

Cold Weather Packages: For operations in extreme cold, the system offers installation packages with heaters, insulated shrouding, and heat trace lines to maintain functionality in temperatures as low as -30°F (-34°C).

Commissioning: Requires the services of a BTl service representative to ensure proper setup and operation.

Installation and Commissioning Requirements: The customer must provide 2 laborers, 1 welder, and a crane with an operator for installation supervision or start-up and commissioning. The customer is responsible for electrical installation and proper site preparation according to the BTl installation manual.

Environmental Specifications: Designed for applications ranging from -25 °F to -45 °F (-32 °C to -43 °C). Includes 2 kW heaters and optional 3 hp circulation pump for continuous oil supply. Insulated shrouding for the main control valve and space heaters for warming slew motors and control valves. Heat trace lines and control panel with ambient sensing thermostat included.

Customer Responsibilities: Insulating hydraulic lines between the power pack and valve. By-passing the energy recovery system in BXR series breakers.

Concave Removal Tool: Used in Gyratory Crushers to safely remove steel liners from the crushing chamber. Consists of a long tool, adapter welded assembly, bolt, hex nut, and washer. Provides a safer and more economical method compared to manual labor.

Tool Configurations and Options: Various tool lengths and types available, including blunt, chisel, and moil ends. Extreme duty kits and wear bar kits available for enhanced durability. Quick coupler and bucket attachment options with pin-on-pin configuration.

Additional Notes: All dimensions and specifications are subject to change without notice. Regular and overtime rates apply for labor, with additional expenses.

MRXT SERIES SALESSPEC/FICATIONSHEETS MRXT APPLICATIONS ABOVE-GROUND GYRATORY BREAKER COVERAGE The gyratory crusher is the mainstay of medium to large duty crushing plants. Typically, material is brought to the crusher by large haulage trucks and dumped into a rock box. The gyratory crusher is located at the bottom of the rock box. Material is crushed between the eccentrically mounted rotating crushing cone and the fixed, tapered crushing throat. The rockbreaker system is typically installed in line with the spider that supports the cone. This provides superior maneuverability of the rockbreaker...
