Double cone mixer for powders and solids
Ensure gentle mixing of fragile powders and solids with a low-speed, non-forced blend to maintain product integrity while meeting high cleaning requirements between batches.

Gently Mixes and Homogenizes Solids and Powders
The Double Cone (MBC) from Bachiller is designed for precise mixing of delicate solids and powders. Its biconical rotary drum gently tumbles products at low speed, minimizing structural damage for fragile materials. Ideal for the chemical, pharmaceutical, and food industries, it’s commonly employed to mix vitamin blends, protein supplements, and resin powders.
With capacity ranging from 200L to 35,000L, the MBC offers batch-wise operations known for their accuracy, achieving a mixing accuracy of 1:10,000 in mere minutes. This mixer ensures complete discharge, reducing product contamination risks during changeovers and simplifying cleaning.
Material-wise, the mixer comes in hygienic finishes, internally mirror-polished to a Ra ≤ 0.6 µm, and can be outfitted with a heating/cooling jacket, liquid injection, or choppers for intensified mixing. Compliance is assured with CE marking under the Safety for Machinery Directive 2006/42/CE, with ATEX options for hazardous environments.
Maintenance is streamlined with low-maintenance design features and options for automated solids loading, dosing systems, and vacuum conveying. Bachiller supports customization and offers engineering assistance to tailor the mixer to your specific processing needs, ensuring seamless integration into your production line.
