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 boom within the gyratory throat. The rockbreaker boom is typically sized to allow the full range of motion over the active area of the rock box. The reach should be deep enough to allow the hydraulic breaker to enter the gyratory for material breaking and liner plate removal applications.
The Vertical Breaker Coverage zone permits superior maneuverability and performance allowing the boom and breaker to operate without subjecting the boom to undue stress. The boom should be positioned and sized so the majority of breaking and raking operations can be done within the Vertical Breaker Coverage zone.
Oversize material that is too large cannot pass through the grizzly and is Iefton top to be broken by a rockbreaker system. The smaller material is allowed to pass through the grizzly down the ore pass. The rockbreaker boom should be sized to allow coverage of the tool over the grizzly with the tool in a vertical position over the main breaking area. The Vertical Breaker Coverage should be positioned well above the working height of the oversize material on the grizzly allowing for maximum

SITE LOCATION For maximum effectiveness, the rockbreaker boom must reach and cover all the problems areas. Proper location is one of the most crucial factors in the successful installation of a rockbreaker system. BTl addresses many variables in the process of sizing a rockbreaker system. Installation drawings are furnished showing the rockbreaker boom's position relative to the crushing site.
Typical questions:
What is the expected duty cycle of the boom and breaker?
Where does material bridge up or slow down?
Where is it practical to break oversize?
Where is the best location to assist material flow into the crusher?
Will the breaker be used to assist in the removal of liner plates in gyratory applications?
Will the boom location allow for positioning out of the way of haulage trucks or scoops?
Will the boom interfere with any structures?
Will the boom location allow safe access to the boom and breaker by maintenance and operation personnel?
SIZING THE BREAKER The MRXT series rockbreaker boom is designed to work with a 4,000 - 8,500 ft·lb (5 400 - 11 500 joule) class hydraulic breakers. The breaker must be sized properly to correctly handle the oversize material's size, hardness, and quantity. A general guideline is listed below. Consult BTl for final sizing of the breaker to the application .
The BX40 is a 4,000 ft·lb ( 5 400 joule) class breaker suitable for oversize pieces of 2-3 yd 3 (1,5- 2,3 m3
) in size, depending on material hardness. This breaker works well in materials with a compressive strength of 20,000-30,000 psi (138 -207 mPa). It is well suited for limestone and softer mineral rock applications on grizzlies up to 20 tph (tons per hour) of oversize, as well as small gyratorys with material production rates up to 2,000 tph.
The BXRSO is a 5,000 ft·lb (6 800 joule) class breaker suitable for oversize pieces of2- 3 yd3 (1,5- 2,3 m3) in size, depending on material hardness. This breaker works well in materials with a compressive strength of 25,000 - 35,000 psi (172-241 mPa). It is well suited for limestone, granite and mineral rock applications on grizzlies with up to 25 tph of oversize, as well as mid-size gyratorys with material production rates up to 2,500 tph.
90900-ENG-1112 www.rockbreaker.com
The BXR65 is a 6,500 ft·lb (8 800 joule) class breaker suitable for oversize pieces of 3 - 4 yd3 (2,3 - 3 m3) depending on material hardness. This breaker works well in materials with a compressive strength of 30,000 - 40,000 psi (172 -276 mPa). It is well suited for limestone, granite and mineral rock applications on grizzlies with up to 30 tph of oversize, as well as mid size gyratorys with material production rates up to 3,000 tph.
The BXR85 is a 8,500ft·lb (11 500 joule) class breaker suitable for oversize pieces of 4-6 yd 3 (3- 4,6 m3
). This breaker works well in materials with a compressive strength of 35,000 -50,000 psi (207 - 345 mPa). It is well suited for granite and harder mineral rock applications on larger grizzlies with up to 35 tph of oversize, as well as large gyratorys with material production rates up to 3,500 tph.

TYPICAL ROCKBREAKER SYSTEM & OPTIONS BTl rockbreaker systems are shipped un-assembled. The following items are included with each shipment:
• Turntable (locate system serial number on rear side)
• Electric Hydraulic Power Pack
• Hydraulic Breaker (if breaker is not to be installed right away, store indoors standing up)
• Outer Boom (Dipperstick Boom), with Tilt Cylinder installed
• Inner Boom, with Dipperstick Cylinder installed
• Hoist Cylinder
• Hydraulic hoses, tubes, options, and any spare parts will be crated separately.
BTl turntable mounted rockbreaker booms are installed on two different types of sub-structure-structural steel and reinforced concrete. BTl can suggest configurations, however customers must determine which is appropriate.
Threaded Tie Rods must be within 1/8" (3 mm) tolerance of dimensions shown on installation diagrams. They should be torqued in a lubricated condition to 1,460 ft·lb (1 980 N·m).
Nylon Mounts sandwiched between the turntable base and substructure help absorb the transmission of shock from the boom to the support structure.
Shims -1/8" and 1/4" (3 mm and 6 mm) supplied with the bolt kit, eliminate irregularities between the two surfaces.
MRXT SITE PREPARATION
22 BREAKER TECHNOLOGY MRXT ROCKBREAKER SYSTEM
REINFORCED CONCRETE INSTALLATION The reinforced concrete pad must be configured to resist the overturning moments and dynamic forces of the stationary rockbreaker system. BTl recommends that all concrete foundation designs are reviewed by a civil I structural engineer and conform to good building practice, local building codes, and site conditions.
The foundation mounting plate is embedded in the reinforced concrete. When installing the foundation mounting plate, make sure all tie rods are vertical, in-line, and within 1 /8" (3 mm) of the dimensions shown in the following Turntable Footprint diagram. A plywood template is included with the optional foundation base plate to assist in positioning the tie rods.

STRUCTURAL STEEL INSTALLATION
A structural steel tower is often used when it is necessary to install the rockbreaker turntable at a required elevation on or beside the crusher.
The structural steel tower and its foundation must be configured to resist the overturning moments and dynamic forces of the stationary rockbreaker system. BTl recommends that all structural steel foundation designs are reviewed by a civil I structural engineer and conform to good building practice, local building codes, and site conditions.

Remote Electro/Hydraulic Joystick Stand (Standard)
This system consists of two dual axis joystick controls with a right-hand thumb switch for breaker fire. The controllers are mounted on a compact control stand making it easy to locate in a crusher control room or other convenient area. An indicator "on" light and a joystick power shutdown button (shutting down power to control valve only) are located on the stand between the controllers.
The main control valve is located on the rockbreaker turntable and allows manual override of all functions.
The joystick controller signal travels through a multi conductor cable to an electrical activating module on each spool of the boom control valve. These modules provide sensitive control for the movement of valve spools giving smooth, positive control of all boom functions.
The power supply for the main control valve solenoids is inside the controller stand. The 120 V to 240 V power "in" and the cable to the power supply are customer supplied. The 24 V cable (30 ft included to maximum 100 ft) from the control stand to the turntable control valve is supplied by BTl. The length required should be determined at the time of order.
• Portable Electro/Hydraulic Joystick
This portable system consists of two dual axis joystick controls with a right-hand thumb switch for breaker fire. Controllers are mounted in a compact control box allowing operation from any position. An "ON" indicator light and joystick power shutdown button (shutting down power to the central valve only) are located between the controllers.
The main control valve is located on the rockbreaker turntable and permits a manual override on all functions.
The signal from the joystick controller is fed through a multi conductor cable to an electrical activating module on each spool of the boom control valve. These modules provide sensitive control for the movement of spools through an internal pilot circuit giving smooth, positive control of all boom functions
Radio Remote Control System
Radio controls allow the operator to work safely from a distance with an approximate maximum sight line distance of 330ft (100m).

IQANTM is a state-of-the-art system, developed to electrically control and monitor hydraulics in a stationary boom system.
IQANTM communicates with and displays data from systems on the rockbreaker, such as the lubrication system, control valve, and etc.IQAN'M also allows control of these systems.
IQANTM is user-programmable via a high-level graphical design tool, dramatically simplifying development. Simulation ofthe control system takes place in parallel with the programming of machine functions.
Servicing is greatly simplified in a number of ways. Sensors can easily be calibrated in the field and any error is recorded

All boom functions are identified by ISO symbols. Functions depend on customer requirements and the rockbreaker system.
Item 1, an Emergency Stop button is found on all controls. An Emergency Stop button is also found on all BTl supplied motor starter panels. It will be operational on any permanently wired control equipment. For controls connected by wire or radio, the button is operational only when the controls are ON and the selector switch turned to the appropriate control. On units with multiple controls, the console and motor starter panel Emergency Stop buttons are always functional, but the optional controls only function when that control is selected and activated.
Left Joystick push-button, item 2, decal shows Left Joystick push-button actions. These functions are available after connecting to the motor starter panel. These functions are active with a BTl supplied starter panel (operations may vary depending on customer requirements). The left button starts the hydraulic motor; the right button stops the hydraulic motor.

The joysticks control the boom functions. Graphic decals show directions.
Joystick control movement is proportional, and affects the speed of the selected boom movement by the distance the joystick is moved from the center.
There is a dead-band zone on the joystick to prevent moving the boom from accidental joystick movement or vibration.
Only slight pressure is required to move the joysticks. Do Not push joysticks past their limit.
Anti-lunge (option) prevents the sudden downward movement of the boom, in the event a hydraulic hose loses pressure. This stops the boom from smashing down onto a rock or through the grizzly grating, damaging the breaker and breaker tool.
