Mix, aerate and crush in one go with Allu TransformerAllu Bucket 350x350px

ALLU Transformer is a bucket that screens, crushers, pulverisers, aerates, blends, mixes, separates, feeds and loads materials. And best of it all, it transforms the materials you work with. Transformer will process just about anything; topsoil, excavated and waste soil, contaminated soil, clay, peat, bark, compost, biowaste, demolition waste, construction waste, milled asphalt, glass, coal, oil shale, lime stone and several other materials.

ALLU Screener Crusher can screen and crush materials from 15 mm to 150 mm fragment sizes.

Widest range on market

ALLU has the widest range of screening buckets and screener crushers on the market. The units fit for almost any base machine size starting from the most compact ALLU DL Series to the massive ALLU M Series that will fit up to 160 tonnes excavator.


Pipeline and cable excavation

By using ALLU Pipeline Padder the excavated soil does not have to be transported away and replaced with new soil. This means significant savings in material and transport costs. No time is lost when waiting for replacement material. At the same time binders can be mixed, if the job requires stabilization.

Industrial applications

Often in industrial applications big particles in the material flow cause problems in processes. With ALLU these big particles can be crushed and the material flow through e.g. conveyers is not interrupted. The unnecessary stops in feeding systems are often costly and time consuming.

Composting , recycling and landscaping

ALLU Screener Crusher is versatile tool when you need to aerate or mix compost to speed up the composting process. By using ALLU mixing, aerating and crushing the bigger materials clumps can be easily done in one step operation. This time saving operation is called ALLUizing.

Soft rock crushing / mining

Crushing and loading the raw material is completed in one step. This reduces the need of buffer storage areas and material transportation.

Investment costs are lower compared to big stationary processing stations. Transportation from one site to another is easy and fast, no expensive special arrangements are needed. There is no need for on site electrics either.
