rock breaking, while the usage of mechanical breaking methods for hard rocks has recently increased mainly in fractured formations. Moreover, mechanical breaking methods involves lower capital costs, higher safety, a cleaner environment and higher strata control than blasting methods. There are several non-explosive or mechanical methods such as hydraulic breaking, ripping, and digging. Hydraulic breaker is used to break up rocks in areas where blasting is not possible due to safety or environmental issues. Breaking is done with a hydraulic hammer, a percussion hammer fitted to an excavator which is typically used for rock excavation and demolishing concrete structures. The performance analysis of a hydraulic breaker typically involves the evaluation of various factors such as impact energy, frequency, noise level, durability and efficiency. Each hydraulic breaker has its strengths and is suited for different operational needs, with Breaker II being the most powerful and heavy-duty, while Breakers I and III offer high efficiency with lighter construction, and Breaker IV providing a balanced option. By evaluating these key metrics, operators can choose a hydraulic breaker that is best suited for actual field working conditions their application to use the machine in productive manner.
The performance of a hydraulic breaker is determined by various factors, including the technical specifications and operational conditions. High impact rate and appropriate tool diameter contribute to effective material breaking. Carrier weight class and hydraulic input power ensure compatibility and efficiency. Maintenance and breakdown hours reflect the equipment's reliability and need for service. Operator skills, jobsite conditions, and proper attachment selection also play critical roles. Regular maintenance, including lubrication and wear part replacement, is essential for sustained performance. Ultimately, a well-maintained hydraulic breaker operated by skilled personnel in optimal conditions will deliver high productivity and efficiency.
1.1 Importance of performance analysis To know the working of hydraulic breaker in mining field with all its specifications. Hydraulic breaker operates by utilizing the hydraulic system of an excavator, where pressurized hydraulic fluid drives a piston back and forth within a hydraulic cylinder. This piston impacts a tool, usually a chisel or moil point, generating high-impact force that breaks the rock or concrete into smaller pieces. The cycle of pressurizing the fluid, moving the piston, and impacting the tool repeats rapidly, often several hundred to a few thousand times per minute, providing a consistent breaking force. Hydraulic breakers are defined by key specifications that ensure their effectiveness and compatibility with specific tasks.
Key Words: Hydraulic breaker, Performance analysis, Fuel consumption, Hardness, Compressive strength, Tensile strength, Noise, Vibrations, etc.
1. INTRODUCTION Mechanical breaking offers significant advantages over blasting, particularly in terms of safety, environmental impact, precision, regulatory compliance, operational flexibility, and cost efficiency. These benefits make it a preferred method in many construction, demolition, and mining applications, especially in urban and sensitive environments where control and minimal disruption are critical. A hydraulic breaker, also known as a hydraulic hammer, is a powerful percussion hammer fitted to an excavator for demolishing concrete structures or rocks. It operates by converting hydraulic energy from the excavator's hydraulic system into kinetic energy, which is

To know the tonnage production achieved per shift and per day. The production achieved by a hydraulic breaker is influenced by several factors, including the impact energy, blow rate, and efficiency of the tool and carrier machine. On average, hydraulic breakers can achieve production rates ranging from several cubic meters to hundreds of cubic meters per hour, depending on these variables. To know the diesel and hydraulic consumption to meet the profitable output. Hydraulic oil consumption by a hydraulic
