Underground mining operations typically use a steel grate called a grizzly to size material before it enters an ore pass. Material that is too large cannot pass through the openings in the grizzly and are left on top of the grizzly to be broken by a fixed pedestal booms system, while the smaller material is allowed to pass through the grizzly down the ore pass.
Grizzly applications are extremely harsh by nature. The fixed pedestal boom system is subject to high degrees of in-line and side raking, combined with various sizes and amounts of oversize. YZH’s stationary pedestal boom systems are designed with wide boom cross sections, extra-large pins and reinforced high tensile steel plates. All designed to handle complex loading to the boom.
Reduce downtime costs of your crusher. YZH brand breaker boom systems are essential to avoid congestion at the crusher intake. Keep on working in spite of jams by installing a Pedestal Breaker that will overcome any eventuality. They are radio‐controlled and have 360° rotation. A complete range with a variety of reaches and features that enable the YZH design a team to tailor them to your crushing plant.
Foundries and steel mills are among the most aggressive environments for operation of any machine. The unique design of the breaker booms system will help you save time in the extraction of all slag and refractory brick. Thanks to their radio control system, Pedestal breaker boom system provide total safety for the operator. They are suitable for areas where access of an excavator is too difficult. A complete range with a variety of reaches and features that enable the YZH design a team to tailor them to your plant.
Big jobs need big stationary pedestal rockbreaker booms systems and hydraulic rock breakers. YZH’s wide range of hydraulic rock breaker booms system allow full breaker coverage within the rock box and mouth of the Crusher. YZH’s complete line of large hammers are designed specifically for gyratories to quickly eliminate any bridging or clogging, restoring consistent material flow to the crusher.
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 fixed pedestal rockbreaker boom system is typically mounted in-line with the upper support of the rotating cone called the spider. This provides superior maneuverability of the stationary hydraulic rock breaker boom systems within the gyratory throat. The boom is typically sized to allow full range of motion over the working range of the rock box. The reach should be deep enough to allow the breaker to enter the gyratory for material breaking and concave removal applications.
Jaw crushers are typically used in many medium duty primary crushing applications. A fixed jaw plate opposite and moving jaw plate size the material through as it passes from the top to the bottom of the crusher. The jaw crusher is typically fed from a rock box by a vibrating feeder.
YZH brand pedestal rock breaker boom systems are suitable for use in Tunnelling applications where hazardous conditions and confined spaces preclude the use of heavy machinery.
The operator works in complete safety with radio‐controlled, YZH static rock breaker boom system and enables you to reduce the size of the material before sending it to the crushing process.
Mobile crushers are, as the name implies, designed to be moved from site to site. An appropriate sized pedestal rock breaker boom system will mount on the crusher securely so the crusher can be moved without first dismantling the breaker assembly yet be large enough to handle the raking and breaking.
A pedestal rock breaker booms system should be positioned to assist with raking rocks into the crusher, reduce oversize, and to be able to reach into the crusher to assist with processing and clearing jams.
