Small dry granulator rounds off the range
Bohle BRC 25 Compactor
Frankfurt/Ennigerloh, June 2015 – With the dry granulator Bohle BRC 25, L.B. Bohle Maschinen + Verfahren GmbH now presents the smaller version of the BRC 100, which was presented for the first time at ”ACHEMA 2012” in Frankfurt. “We now have rounded off our comprehensive offer of granulation solutions”, explained Lorenz Bohle. Easy handling, continuous production and a small footprint are the typical features with which Bohle now covers the comprehensive portfolio of wet and dry granulation.
The concept of the BRC: In the roller compactor, powder is processed to free-flowing granulates. The objective in the pharmaceutical industry is to achieve a granulate with defined density or porosity for subsequent tableting. The powder is fed in via a dosing unit, compacted between two rollers with gaps ranging from 1 to 6 mm and discharged as flakes. The impact on the rollers as well as the gap width are monitored sensorially. All data are integrated into a control circuit to continuously ensure optimum process parameters.
The chopper unit below the compact rollers processes flakes into granulates. The unit is equipped with a conical sieve with exchangeable sieve units to achieve different particle sizes.
Well equipped for customers’ requirements:
Simple control, easy cleaning and fewer edges, screws and angles - these are the essential features that already distinguished the BRC 100.
Especially the control of the pressing force via standard hydraulic systems constitutes a great problem, when the process is to comply with “hygienic design”. The electro-mechanical batch can solve this problem. With the Bohle BRC 25, frequent adjustment of the axes as with traditional roller compactors is a thing of the past, The axes are mechanically stable so that elastic deformation is prevented. This eliminates the need for complete axes control. Moreover, the BRC 25 is low maintenance. Even when cleaning is required, only four screws must be removed. Bohle engineers also reduced the footprint. Further advantages of the BRC series are the identical roller geometry and control in both machines allowing for easy scale-up.
Lorenz Bohle: “We are now able to offer our customers machines and processes for all stages of the granulation process with our new BRC 25 – continuously with the proven Bohle quality”.
