Key Components of a SKE Pedestal Boom Rock Breaker System
SKE Pedestal Rock Breaker Boom System is a stationary unit, a machine designed to manipulate large rocks, including reducing large rocks into smaller rocks. They are typically used in the mining, quarrying, aggregate, cement, metallurgical and foundry industries to remove oversize rocks that are too large or too hard to be reduced in size by a crusher or grizzly.
SKE Pedestal Rock Breaker Boom System consists of four major components: pedestal boom, hydraulic hammer, hydraulic power unit, and operating control. We are one of the largest manufacturers of these machines, exporting to Dubai, Abu Dhabi and other parts of the UAE, Saudi Arabia, Oman, Kuwait, Qatar, Bahrain, Iraq, Egypt, Malaysia, Singapore and more.
Applications
1. Underground or Opencast Grizzly Screen (Grid)
Grizzly applications are extremely harsh by nature — a continuous primary crushing process. SKE grizzly Pedestal Rock Breaker Boom Systems are designed with wide boom cross sections, extra-large pins and reinforced high-tensile steel plates. The boom is subject to high degrees of in-line and side raking, combined with various sizes and amounts of oversize, and is built to handle complex loading whether below or above ground.
2. Stationary Primary Crushing Plants
Jaw Crusher & Impact Crusher — Jaw crushers and impact crushers are most often fed from a rock box using a vibratory feeder. SKE high-strength Pedestal Rock Breaker Boom Systems are mounted on crushing-line steel structure, concrete foundations, or a separate supporting column to break excessively large stones or unblock the transport route to crushers. The boom system reduces oversized boulders, rakes rock material into the crusher, and reaches into the crusher mouth or hopper to assist with processing and clearing jams — a simple, cost-effective and safe breaking solution with the widest range of boom reach and breaker sizes in the industry.
Gyratory Crusher — Big jobs need big rock breaker boom systems. SKE's wide range of gyratory Pedestal Rock Breaker Boom Systems allow full breaker coverage within the rock box and mouth of the gyratory crusher, quickly eliminating any bridging or clogging, restoring consistent material flow to the conical crusher, or releasing cave-ins (vaults) in the cone crusher. These systems are usually placed on the rugged steel structure of the cone crusher.
3. Mobile & Portable Crushing Plants
Mobile crushers use small rock breaker boom systems mounted directly on the structure of the mobile crusher, so it can be moved without first dismantling the boom system assembly — yet large enough to handle the raking and breaking. SKE mobile crusher Pedestal Rock Breaker Boom Systems are compact, tough and fitted with high-powered mine- and quarry-duty hydraulic hammers for maximum performance.
4. Foundry Industry & Metallurgical Industry
Foundries, metallurgical smelters and steel mills are among the toughest working environments. The SKE custom pedestal boom system has a unique design that helps factories improve work efficiency (such as saving time in the extraction of slag and refractory brick), and plays an efficient, safe role in shelling, brick breaking, unpacking and slag cleaning of metallurgical furnaces and mobile ladles. With a 2-in-1 radio remote control system, SKE pedestal boom systems provide total safety for the operator and suit areas where excavator access is too difficult.
5. Other Uses
We provide professional customized services according to the actual working conditions and needs of the end user — including recycling plants, tunnelling, digging cement in cement plants, assisting car dumpers to unload, port coal unloading, railway wagon planishing, grabbing and transporting garbage at municipal waste treatment stations, digging clams at sea, removing rust from ship hulls, and loading, unloading and handling timber.
