EBZ75 cantilever-type roadheader as hard rock cutting machine size is narrow, hydraulic system is simple and reliable, low maintenance, adapts to minimum cross-section of about 5 square meter.
EBZ75 as a roadheader mining equipment for rock cutting is suitable to work in coal mine, engineering excavation, potash mine, sodium, bauxite and other geological conditions with hardness co-efficient upto F4. Equipped with a national patented scraper conveyor, it can transport coal, gangue, dregs, rocks and other materials without any blockage and can achieve rapid excavation and uninterrupted transport.
Main characteristics of this machine are: compact structure, short machine body, low center of gravity, convenient operation and stable when working. Cutting head is driven by motor without strong overload capacity. All components are reasonably designed to be small part combination for the convenience of underground transportation and installation. It is equipped with internal spraying system with good de-dusting effect. Hydraulic system is simple and convenient to maintain.
Electronic Control System
EBZ75 road header adopts explosive-proof and intrinsically safe switch box and intrinsically safe operation box which are small in volume, light in weight, flexible in operation, safe and reliable; main controllers are mounted in a sealed shell to shield electromagnetic interference effectively; working conditions are displayed on LCD screen. It has over-voltage, motor-overload, short circuit, and earth leakage lockout functions.
EBZ75 type road header adopts constant power, pressure cut off and load sensitivity control.
Cutting head is optimized with emulation technique; cutting tooth layout is reasonable and rock breaking capacity is strong.
Spraying system of EBZ75 type road header consists of internal spraying system and external spraying system. Internal spraying system is to spray behind teeth. It possesses water leakage detecting function. Design of external spraying system is effective.
First conveyor adopts straight structure and is connected with insertion board smoothly. The conveying operation is unobstructed.
Traveling driving system integrates motor and reduction gear with internationally advanced technology. Its output torque is large and it is suitable for operation with large dip angle. If there is limit on weight or overall height during transportation, the roadheader can be dis-assembled to transport.
