Twin Shaft Concrete Mixer
Models：JS500
The JS500 Twin Shaft Concrete Mixeris an ideal and advanced model both at home and abroad. It is capable of mixing semi-dry, stiff, plastic concrete, lightweight aggregate concrete, and various mortars. This machine adopts a new lifting device and mixing arm connection method, which further improves the operational reliability of the whole unit. It features fast material mixing, high productivity, uniform mixing, and excellent quality. As the main supporting machine for the HZS25 concrete mixing plant, the JS500 twin-shaft compulsory mixer boasts a long service life and high output.The JS500 mixer can be used independently or as the main machine for mixing towers and mixing plants. It is suitable for general construction projects, road and bridge engineering, and small precast component factories.
Mixing System
· The mixing system of the JS500 Twin Shaft Concrete Mixer consists of an electric motor, belt pulley, reducer, open gears, mixing drum and mixing device, oil supply unit, and other components.
· During operation, the electric motor drives a two-stage gear reducer. The two output shafts of the reducer drive two horizontal mixing shafts to rotate reversely at a constant speed via two pairs of open gears.
Feeding System
· The feeding system of the JS500 Twin Shaft Concrete Mixer includes a hoisting mechanism, feeding frame, hopper, feeding spout, and other components.
· The brake motor ensures the hopper stops reliably at any position under full load. The braking torque is adjusted by the large nut at the rear of the motor.
Water Supply System
· The water supply system of the JS500 Twin Shaft Concrete Mixer is composed of a water pump, throttle valve, cleaning and spraying device.
· The throttle valve regulates the water flow rate, and the total water supply is adjusted by a time relay.
Discharging System
· The discharging system of the JS500 Twin Shaft Concrete Mixer consists of a discharge door, air cylinder, or hydraulic cylinder.
· Three control structures are available: hydraulic control, pneumatic control, and manual control.
· The discharge door is installed at the bottom of the mixer. Discharging is achieved automatically via an air cylinder or hydraulic cylinder.
Electrical System
· The electric control circuit of the JS500 Twin Shaft Concrete Mixer is equipped with an air switch, fuse, and thermal relay, providing short-circuit protection and overload protection.
· All control buttons, air switch handles, and indicator lights are mounted on the distribution box door, which is fitted with a door lock.
· The electrical components inside the distribution box are installed on an insulating plate, ensuring safety, reliability, and convenient operation and maintenance.
