Conical Sieves for the pharmaceutical industry
Conical Sieves - BTS
Conical Sieves are used to crush solids. Due to their versatility, Conical Sieves play a crucial role in pharmaceutical production. They can be integrated into complex production lines, for example for filling/emptying or transfer processes on process machines or for filling and transferring containers.
More about the highlights
The Sieving BTS is used for the uniform size reduction of pharmaceutical ingredients. The sieve unit can also be used for mixing and dispersing. Sieves are available in a variety of different sizes - from laboratory scale to high capacity plants.
Compared to other shredding technologies on the market, the L.B. Bohle screening plant offers numerous advantages for production:
- Lower noise emission
- Narrow distribution of Particle Sizes
- High design flexibility
- Higher capacity than comparable systems
When processing low-density materials, the BTS can increase throughput by more than 50 % compared to conventional mills.
The Turbo Sieving BTS is used to calibrate the Particle Sizes and thus guarantees an optimum particle size distribution.
By using different conical sieve inserts (perforated sieve and friction sieve), both dry and moist products can be processed at a speed of 150 to 1,500 rpm. Product capacities of two to three tonnes can be achieved within one hour.
Convenient operation is via a 7" touch panel, which enables user and recipe management as well as PDF batch print management and has a USB interface. The explosion-proof version of the Turbo Sieving can also be used in accordance with ATEX directives.

L.B. Bohle offers innovative grinding and sieving systems that are essential for pharmaceutical production. Their conical sieves and Hammer Mills, such as the Bohle Turbo Sieve BTS and Bohle Turbo Mill BTM, ensure efficient particle size reduction and homogenisation. These compact, easy-to-clean devices improve production flexibility and increase efficiency, ideal for research, development and high-volume manufacturing processes.
Why does sieve technology play a central role in pharmaceutical production?
Conical Sieves ensure precise particle size distribution, which is crucial for solution speed, homogeneity and miscibility. They can be flexibly integrated into production lines - e.g. for filling, emptying or transfer processes - and thus contribute to Process Safety and quality.
What makes the Turbo Sieving BTS from L.B. Bohle so special?
The patented agitator blade design, the variable screen speed of 150 to 1,500 rpm and the use of different conical perforated and friction screens enable the processing of dry and moist products at a capacity of up to 3 tonnes per hour.
How easy is it to clean and operate the BTS?
The easy-to-clean design with bayonet lock and clamping ring allows for quick disassembly and manual cleaning. Optional integrated WIP cleaning nozzles ensure automated internal cleaning, while the 7" touch panel enables intuitive operation, recipe management and log output via USB.
What advantages does the optional RFID technology offer?
The system automatically recognises the sieve insert used and thus prevents incorrect recipe allocations. Operating times can also be recorded, which helps to recognise wear at an early stage.
