A dry mortar plant runs the same recipe thousands of times. The mixer does not need to be clever; it needs to hold its tolerances while eating sand, cement and mineral filler shift after shift.
Ribbon mixers do most of this work: 100 L to 4,000 L batches, wear-resistant troughs and agitators, and a discharge that empties completely so the next batch is not contaminated by the last. Wet or high-viscosity products — gypsum plasters, repair mortars, some tile adhesives — move to a double paddle machine instead.
Built for abrasive, continuous duty
Wear resistance
Hardfaced agitators, replaceable wear strips and heavy-gauge troughs for sand- and cement-based products.
Throughput
Batch sizes from 500 L to 4,000 L with cycle times that let the plant hit its tonnage per shift rather than per hour.
Bulk handling
Big bag filling with a dust-tight inflation seal, plus screw conveyor loading from silos so the mixer is fed at a controlled rate.
Continuous-duty reliability
Heavy-duty geared motors, oversized bearings and a frame designed for 24/7 operation rather than intermittent batches.
Construction material applications
Dry mortar
Cement, sand, cellulose ethers and redispersible powders blended at 2,000–4,000 L per batch.
Tile adhesive and grout
Cementitious and epoxy-based formulations with fine fillers and polymer additives, where short cycles must still give a uniform colour.
Gypsum and plaster
Stucco, joint compound and plaster of Paris — high-viscosity products that need a paddle machine rather than a ribbon.
Putty powder
Wall putty, skim coat and smoothing compounds: fine fillers plus binder, blended to a consistent texture.
Self-levelling compounds
Cement- and calcium-sulfate-based floor levellers, where trace additives decide flow behaviour.
Waterproofing and repair mortars
Polymer-modified coatings and repair products with latex or polymer liquid addition during mixing.
Construction-grade equipment
Ribbon Mixer (WHJ)
The standard machine for dry mortar and construction powder, with wear-resistant trough and agitator options. 100–4,000 L.

Frequently asked questions
What is the largest batch available?
The ribbon mixer goes to 4,000 L gross volume — roughly 2,400–2,800 kg on a typical dry mortar at 1.2–1.4 bulk density.
Will the machine survive sand and cement?
Yes, with the wear package: hardfaced agitator, replaceable liner strips and heavy-gauge trough. We quote the liner as a consumable so replacement is planned rather than a breakdown.
Can it be fed from a silo?
Screw conveyors handle silo-to-mixer transfer at a controlled rate, and dust collection at the charging point keeps the plant clean.
