The construction and mining industry depend heavily on using crushed rocks or ores for specific applications. For crushing rocks, a specific device known as rock breaker is being used. This machine is specifically designed for tough crushing operations. The rock breaker is most commonly used in the mining industry for reducing the size of rocks that are either too hard or too large. The rock breaker can be either stationary or mobile, but generally, it is used as a mobile unit for increased flexibility.
The rock breaker is known for using a simple, but efficient “crushing” principle. The pressure from the upper chamber of the piston is always higher than the pressure from the lower chamber. When the pressure from the upper chamber is reduced, the piston moves upwards. The back head, positioned above the piston, is full of high-pressure N² gas and gas energy, specifically stored for the piston. Then, the pressure is transmitted to the tool, which uses the energy for breaking large rocks.
Despite the wide range of rock breakers on the market, they are all composed of similar parts. The main parts of every rock breaker are: tie rod, back head, cylinder, valve, piston, tool and accumulator. The tie rods are usually heavy-duty, because the rock breakers are used for difficult crushing applications. The back head, front head and the cylinder are all tightly fixed with four tie rods. The cylinder is the main part of the rock breaker, and it contains a hydraulic circuit for piston. By hitting the rock, the piston changes the kinetic energy into hammering energy. Then, the tool uses that hammering energy to break rocks. The accumulator is used to compensate the lost pressure from the process of creating hammering energy.
Every rock breaker comes with fully enclosed housing for maximum protection from dirt and debris. For enhanced safety and comfort, the rock breaker has shock absorbers positioned at the top. The recoil energy and mechanical forces are absorbed, meaning that all components are protected from vibration. At the bottom, the rock breakers feature high-grade steel bushings for proper vibration isolation. However, for proper operation, all parts of the rock breaker need to be well-lubricated. Auto-lube systems are the ideal solution, as they provide proper greasing procedure.
