The invention provides an ore crushing
machine suitable for different sizes. The
machine comprises an ore crushing
machine body, a material conveying
conveyor belt, a feeding
conveyor belt, a baffle plate, an
initial treatment device, a feeding hopper, a crushing box, a material discharging opening, a gearbox, a motor box, a control box, a
power control panel, a second motor, a rubber base, a belt, a third motor, supporting legs,
conveyor belt rolling roller, a
combustion box, a water tank, a water pump, a gas tank, a gas delivery
pipe, a first pressing plate, a crushing table, a first
hydraulic cylinder, an electric
drill, a second
