YZH China Stationary Rock Breaking Boom
In Gobi mining areas, strong winds, arid conditions and frequent jamming of large rock blocks at crusher hoppers are persistent pain points for aggregate production lines. A large sand and stone mine project in Northwest China previously relied on manual work plus mobile excavators to clear blockages at the feeding opening. When large ore wedged at the grizzly, production had to stop, and workers entered hazardous zones for blasting and rock prying. A single blockage clearance took 1 to 3 hours, causing frequent production interruptions, prominent safety risks, high fuel consumption and soaring labor costs.
To tackle blockage issues, the project adopted the YZH China Stationary Rock Breaking Boom, installed beside the grizzly feeding chute. It is specially used for secondary crushing of large rocks at the feeding port, fundamentally eliminating shutdowns caused by blockages.

Project Pain Points (Before Retrofit)
1. Frequent blockage of large stones at the feeding opening forced repeated production shutdowns and restricted output capacity.
2. Extremely high risks for manual clearing: workers operated close to the feeding chute with severe falling rock hazards.
3. Mobile excavators deployed for blockage removal brought high fuel consumption, heavy equipment wear and high comprehensive operating costs.
4. Heavy sandstorms and sharp day-night temperature differences in the mining area made ordinary construction machinery prone to failures with frequent maintenance.
On-site Equipment Performance
Built with a unique transmission principle, the YZH China Stationary Rock Breaking Boom features a compact and well-designed structure, stable operation and low noise. Compared with conventional crushing solutions, it achieves up to 70% energy saving and helps enterprises double production capacity. Meeting dual requirements of resource exploitation and environmental protection, the product adopts multiple groundbreaking technical innovations, with core performance comparable to world-class advanced standards.
Core Practical Advantages
- High-efficiency crushing & upgraded production capacity
Equipped with a high-quality hydraulic breaker, it delivers powerful crushing impact and stable operation. Easy maintenance greatly cuts equipment overhaul time and continuously solves large rock blockages at the feeding chute to guarantee continuous assembly line operation.
The equipment is fixedly mounted on one side of the feeding grizzly and requires no repositioning. once large rocks get stuck, the manipulator quickly moves into position for crushing, without moving heavy machinery to the site. Blockage handling time is shortened to more than ten minutes, greatly improving production continuity.
- Full-scenario adaptability, reliable under harsh working conditions
The mine is located in the Gobi desert with heavy sandstorms and extreme day-night temperature fluctuations, representing typical tough operating conditions. The YZH China Stationary Rock Breaking Boom has strong environmental resistance and can run stably long-term in such open-air desert environments.
Various front-end working tools are interchangeable to flexibly match different material crushing requirements. It can process hard rocks such as granite and quartzite, realizing seamless application across multiple working conditions.
- Safety-oriented, stable and reliable
Fitted with a high-performance shock absorption system, the whole machine structure is optimized via simulation with a scientific layout. Designed with a high safety factor, it allows operators to conduct remote control from an independent operation cabin. No personnel need to approach the dangerous feeding zone, completely eliminating the high-risk operation of manual clearing inside the grizzly and fundamentally removing the risk of falling rock injuries.
The integrated shock-absorbing structure absorbs crushing impact, and the base is firmly fixed. It rarely loosens under long-term high-frequency operation with low overall failure rate.
Project Outcomes
After commissioning, the production line’s downtime for blockage clearance dropped by 90%, and the effective operating time increased significantly. Compared with the previous excavator-based clearing method, energy consumption was reduced by 70%, saving substantial annual costs on fuel, maintenance and labor.
On-site operators commented: The equipment runs steadily in the Gobi environment and is simple to maintain. Staff no longer need to take risks clearing large rocks at the feeding opening, achieving both higher output and improved safety.
Customer Testimonial: "Blockage used to be the biggest headache for our production line. Every jam meant long downtime, and we were always worried when workers went down to clear rocks. The YZH China Stationary Rock Breaking Boom is installed at the feeding chute, crushing rocks immediately when blockages occur. No excavators running back and forth, low energy consumption. Operators control remotely from the cabin, safe and worry-free. It truly safeguards our production capacity."
Extended Applicable Scenarios
Besides sand and stone mines, this stationary breaking manipulator is also suitable for metal ore processing plants, quarries, construction waste recycling production lines, etc. It can handle complex environments including explosion-proof conditions, corrosive surroundings and high-altitude regions, serving as the preferred solution for secondary crushing of bulk materials and blockage management at feeding openings.
