JS500 forced concrete mixer, with a discharge of 0.5 cubic meters per time, also known as 0.5 cubic meter concrete mixer, has an hourly production rate of 25m3/h. It is mainly used as the main unit of HZS25 mixing plant and can also have the dual advantages of single machine independent operation and PLD series concrete batching machine (also known as concrete batching plant, concrete batching silo) to form a simple concrete mixing plant.
JS500 is a widely used high-efficiency concrete mixer that uses a motorized discharge system and can be used in conjunction with a dump truck. It mainly consists of a mixing drum, hopper feeding rack, hoisting mechanism, mixing drum, mixing blades, mixing shaft, mixing arm, frame, unloading mechanism, oil and water supply system, and electrical system. Suitable for mixing plastic, dry hard, lightweight aggregate concrete and various mortars and mortars, it is an ideal tool for various construction sites.
●The JS500 concrete mixer mixing system consists of components such as an electric motor, pulley, reducer, open gear, mixing drum, and oil supply device.
●When working, the electric motor drives the secondary gear reducer, and the two shafts of the reducer drive two horizontal mixing shafts to rotate in opposite directions at a constant speed through two pairs of open gears.

●The feeding system of JS500 concrete mixer consists of components such as hoisting mechanism, feeding rack, hopper, feeding nozzle, etc.
●The brake motor ensures that the hopper can reliably stop at any position during full load operation, and the magnitude of the braking torque is adjusted by the large nut on the back seat of the motor.

●The water supply system of JS500 concrete mixer consists of water pump, throttle valve, cleaning and spraying device.
●The throttle valve can adjust the flow rate of water, and the total amount of water supply is regulated by a time relay.

●The JS500 concrete mixer unloading system consists of unloading doors, cylinders, or hydraulic cylinders and other mechanisms.
●There are three types of structures: hydraulic control, pneumatic control, and manual control.
●The discharge door is installed at the bottom of the mixer, and is powered by a cylinder or hydraulic cylinder to achieve mobile discharge.
●The electrical control circuit of JS500 concrete mixer is equipped with air switch, fuse, and thermal relay, with functions of short circuit protection and overload protection.
●All control buttons, air switch handles, and indicator lights are arranged on the distribution box door and equipped with door locks.
●The electrical components inside the distribution box are mounted on a flange, which is safe, reliable, and easy to operate and maintain.
