Still stuck in hard rock mining? The "slowness, danger, and high cost" of traditional blasting/hydraulic hammers are being completely solved by mining excavators with breaker! This article compares two operation modes and combines real cases of iron mines in Ontario, Canada, to help you calculate the "efficiency account".
Traditional hard rock mining: The triple dilemma of time-consuming + risky + high cost
Blasting method: Requires advance approval, hole drilling, and site clearance; a single operation takes 8-12 hours, and is prone to flying rocks and vibration damage to equipment;
Hydraulic hammer breaking: A single hammer processes only 0.5-1 cubic meter of rock per hour; when hardness >12MPa, repeated hitting is required, resulting in fast cylinder wear, with maintenance costs accounting for 30%.
Mining excavator with breaker: An all-in-one "mining accelerator"
Mining excavator with breaker drives the breaker through the hydraulic system, directly embedding it into the machine body to realize integrated "excavation + breaking" operations:
The impact force of mining excavator with breaker is adjustable: Adaptable to different hard rocks such as granite (Mohs hardness 6-7) and basalt (hardness 5-6); the hydraulic hammer frequency can be freely switched between 30-80Hz;
Efficiency soars: A single hammer processes 2-3 cubic meters of rock per hour, 4-6 times higher than hydraulic hammers;
Safety and cost reduction: No need for blasting approval, reducing the risk of personnel exposure; moreover, the service life of breaker accessories is extended by 2 times (Hengwang's patented hydraulic buffer technology).
Foreign verification: The "speed-up myth" of iron mines in Ontario, Canada
An iron mine in Ontario, Canada, originally used a combination of hydraulic hammers and blasting, with a daily processing capacity of only 800 tons and an average monthly downtime for maintenance of 4 days. After switching to mining excavator with breaker:
The daily processing capacity exceeded 1200 tons, and the average monthly downtime was reduced to 0 days;
Annual savings in labor + maintenance costs exceeded $800,000, with an investment return cycle of only 6 months.
