Product Introduction
With the continuous improvement and large-scale mining equipment, the internal liner bolt removal work automation of large mills is also increasing. At present, the domestic enterprises in the replacement of ball mill liner, the removal of liner bolts mostly said to use manual impact type, resulting in low efficiency and high labour intensity. There are safety hazards, long time to change the lining and backward technology, is a traditional method of removing bolts. The time consumed to remove the bolts of a medium-sized mill is as short as 15 days and as long as 20 days. It is also an operation method that cannot be changed by mining enterprises.
Our MC2-150B bolt punch is to improve the traditional way of removing bolts, shorten the time of mill liner replacement and the development of high-efficiency hydraulic bolt punching products, in the replacement of a large and medium-sized ball mill liner removal of bolts in only 5 days, greatly improving the equipment utilisation. Bring higher benefits to the use of units.
MC2-150B bolt punch has large impact force, no recoil, easy operation and accurate positioning. It is the preferred equipment for ball mill liner bolt removal.
Main technical features
1: The power system adopts electric motor drive, no harmful gas emission, the hydraulic system adopts variable system, the system heat is small, low noise, energy saving and environmental protection.
2: High degree of intelligence, integrating hydraulic control technology and hydraulic vibration technology.
3: Bolt punch has horizontal spreader and vertical spreader, plus the auxiliary role of the guiding sleeve, can smoothly remove the horizontal and vertical bolts.
4: The whole machine is equipped with economic and practical, exquisite design and reliable quality. Maintenance is simple. Comfortable operating environment and low labour intensity.
MC2-150B Bolt Punch Product Introduction
According to our company's more than ten years' experience of bolt punch production, and also has been constantly summed up and improved, we are now launching a MC2-150B bolt punch, from the hydraulic system to the structural parts, the electric control part adopts a brand-new design, which ensures that the bolt punch is more efficient when working.
I: The structural parts are laser cut and discharged, semi-automatic and automatic welded, polished and descaled, and sprayed with plastic in the assembly line, with strong colour adhesion and smooth and glossy surface. The colour has a long shelf life and does not fade.
2:Bolt punch body is the key core components, punch body cylinder body spool, and a full set of seals are imported from South Korea supporting parts. Adopt Korean technology to make the punch body in pressure resistance, wear resistance, high temperature resistance and other aspects of a better quality assurance. Make the bolt punch in the work of oil pressure pressure balance. Vertical maximum striking force is increased to 360 joules. Horizontal striking force is 1800 joules. The operation can be point strike, can also be continuous strike, efficiency improved.
3:Improvement of the bolt punch's focus when it is safe to produce. Reduce and eliminate recoil, the back end of the improved punch body increased air shock absorption buffer spring. Adding nitrogen gas, so that the recoil force when striking is cushioned and reduced. The operator has no obvious recoil feeling when striking the bolt, which ensures the personal safety of the operator.
4: the electronic control part, the main motor using the total opening and stopping control, the oil pump steering is clockwise steering, in order to prevent the opposite steering, damage to the oil pump, now installed phase sequence protector, to ensure that the motor does not turn when the wiring is not correct. Only when the wiring is correct will the motor start to drive the oil pump work. Increased hydraulic oil temperature indication, hydraulic oil level protection, electrical fault protection and oil return indication protection. And equipped with emergency stop switch, control box shell made of stainless steel, electrical components using Schneider brand. Supporting parts are of high quality brands at home and abroad.
The overall appearance of the design is exquisite and reasonable, (and has obtained the national invention patent), practicality, mobile and flexible, beautiful and generous advantages.
