Cement Mixers

Altrad Belle and Altrad Expert are two separate product lines within one industrial group. Belle descends from the British Belle Group and is positioned as professional equipment — drums from roughly 130 to 250 l, drives of about 0.55–1.1 kW, and a structure engineered for multi-hour cycles across a whole season. The Expert line sits in a cheaper segment aimed at light construction jobs and one-off renovations. The gap shows up in how the drum and crown gear are made, and in how long the machine keeps running under full load. Our range concentrates on the Belle line.

MINIMIX and BWE identify two families of machine. MINIMIX covers the smallest, portable mixers with drums of roughly 130–150 l that one person can wheel across a site and lift onto a trailer. BWE is the site series, with a drum reaching about 250 l, a reinforced frame and versions for both 230 V and 400 V supply. The number in the model designation gives the nominal drum volume in litres, which is not the same as usable output: a 250 l drum yields around 150–175 l of finished mix per batch, because the material needs room to tumble as the blades rotate.

The choice starts with the power available on site, because it rules out part of the range before litres matter: with no three-phase board you are left with single-phase 230 V machines, while a CEE socket opens up the 400 V versions of the BWE series. Drum capacity is the second step — roughly 130–150 l covers renovation work and masonry mortars, some 180–200 l fits house building, and a 250 l drum pays off only where concrete is poured across a whole shift. Transport is the third criterion: a larger drum means a heavier frame and fewer moves between sites.

The weight of a free-fall site mixer scales with drum volume and usually stays below 100 kg in the compact 130–150 l format and exceeds 100 kg with a drum of about 250 l. Every machine has transport wheels and a handle, so one person rolls it across a firm surface, while loading it onto a trailer or into a van is a two-person job or one for a ramp. For transport the drum is turned mouth-down and the power plug is protected against moisture. Exact mass is given in the technical data on each product page.
