JS500

The JS500 concrete mixer is a twin-shaft forced mixer for small batch production. A nominal discharge of 500 litres per cycle and an 800 litre input volume let it serve precast yards, block plants and small site batching without a heavy foundation. Two 18.5 kW motors drive the shafts.
Staggered blades push material through the chamber in a forced action, so plastic, dry-hard and lightweight aggregate mixes reach a uniform state faster than a gravity drum. An inspection window lets operators watch the mix, and a 5.5 kW winch handles the skip where the layout calls for one.
Most orders for the JS500 concrete mixer ship alongside an HZS25 arrangement, with the mixer under the batching frame and a PLD series machine feeding it. Standalone use is common too, with a manual or small hopper feed and a 0.75 kW water pump for the mix water.
Selection comes down to batch size and cycle count. The JS500 concrete mixer returns about one cubic metre per cycle, so daily output follows how many cycles the crew can sustain across a shift. Confirm grades, aggregate sizes and slump range before fixing the configuration.
