JS series Concrete Mixer

JS series concrete mixer is a kind of double shafts forced type mixer, it can be used separately and can be used together with a concrete batching machine to be a simple type concrete batching plant. It is being widely used in various scale of prefabricate concrete parts factory, and much construction of road and bridge, dam, port and so on. It could be used to produce dry concrete, plastic concrete, fluidity concrete, lightweight aggregate and various kinds of mortar.

What Defines a Good Concrete Mixers

Wear is the real operating cost. Shaft-end seals, liner plates and mixing arms are therefore designed as replaceable assemblies, dimensioned so that maintenance crews can change them on site within a single shift.

Every cubic metre of structural concrete passes through a JS series Concrete Mixer. The machine has one job — distribute cement paste evenly around every aggregate particle in the shortest possible cycle — and when it fails, the failure shows up as strength scatter, segregation during pumping or rejected truckloads.

Optional tilt/hoist configurations

Available as bare mixer, skip-fed unit, or mounted on a complete plant frame.

Short cycle times

Twin-shaft machines reach full homogeneity in 30-40 seconds, keeping pace with the batching sequence.

Heavy-duty gearboxes

Planetary gear reducers with forced lubrication are selected for 24/7 duty cycles.

Buying Questions Answered

How often should liners be replaced?
Typically after 60,000-100,000 batches for a twin-shaft mixer using rounded aggregate; angular or highly abrasive aggregate shortens that.
How do I size the mixer to my plant output?
Match batch size to the plant.s rated hourly output divided by the number of batches per hour — normally 40-50 for a twin-shaft installation.
Twin-shaft or planetary?
Twin-shaft wins on throughput and simple maintenance for ready-mix volumes; planetary gives superior homogeneity for low-slump, coloured or fibre-reinforced mixes and is preferred in precast.
What maintenance is needed on the shaft seals?
Automatic grease injection every shift and shaft-end seal inspection weekly; seals are normally replaced annually.
