The first L.B. Bohle container blender was produced in 1987, and the German technology company has since manufactured thousands of blenders. Every day, many blending systems are employed on production lines worldwide.
L.B. Bohle has risen to the top of the pharmaceutical container blender industry due to its creative design, adaptability, and long service life.
High flexibility and scalability
The blender product portfolio is distinguished by its great degree of flexibility in design and production. This allows the blenders to be customized to the customer's production needs and daily demands.
All Bohle container blenders are employed in every possible pharmaceutical, chemical, and nutraceutical manufacturing production situation. Thanks to the proprietary mixing devices fitted on the inside of the container lid, all blending methods achieve a very homogenous blending of the powder batch.
Depending on the method, scalability might reach 12,000 liters. Blending containers are typically supplied as exchangeable containers with a volume of up to 2400 liters.
Innovative blending methods enable effective blending for densities ranging from 0.2 to 1.2 kg/dm³, with each container capable of combining 20-85% of the entire container volume.
Another major design characteristic is the selection of pick-up systems: L.B. Bohle provides its customers with five alternatives.

Electronically monitored quick clamps
Versions with conventional load arms and clamps are the most commonly requested. Containers are docked with four electrically monitored fast clamps. Containers with a volume of up to 1200 liters fixed on an undercarriage can be attached to the blender without additional lifting equipment.
A chopper can also be fitted in the container lid. The drive for this chopper is built into the blender's load arm. Another blender design allows the machine to swivel around its vertical axis.
This enables optimum customization to the customer's needs. This design also has a long service life and requires very little maintenance.
Another popular variant of the pharmaceutical blender involves sliding the container and adapter tubes onto two receiving mandrels. Two screws on the front side secure the container and keep it from slipping. The container is lifted and rotated through the mixing system, just like in previous Bohle mixing systems.
Ideal solution for automated container pick-up
The load arm of the third edition of L.B. Bohle mixing systems has eccentric clamps. Containers are picked up with tines and clamped automatically by eccentric movement in pick-up tubes, also known as adapter tubes.
This extremely safe pick-up system works well for automated container pickup, such as on a guide rail. If the containers have a circumferential frame, they can be picked up and laid down in an inverted posture. This model is also available as a swivel version, which can be spun around the vertical axis.

A fourth variant comes with load support and power clamps. These apply pressure to the upright's lower frame, keeping the container securely clamped to the load support.
They may be adjusted using the upright or the machine's support rails. To fit current blending processes, load handling can be done straight or at an inclination of up to 30 degrees. This system has proven itself over many years of operation with Bohle's SFM mixers.
The fifth variant uses hydraulic clamps on the load arm. Containers are hydraulically fastened between the load arm's fixed and movable sections. Various sensors and suitable controls ensure that the system operates safely.
The load-handling system can be tailored to different types of containers. It can also take up containers at an angle of 30°. Combined with a lifting unit, the design is extremely adaptable and has a tiny footprint.
All five types of L.B. Bohle mixing systems exhibit the design's adaptability, regardless of the container used in production.
Conclusion: Bohle blenders can mix circular or square containers with great results.

Laboratory blenders for research and development
L.B. Bohle created the LM 40 laboratory blender primarily for research and development applications. It provides high flexibility, mobility, scalability, and rapid discharge. Modern laboratory blenders are designed to provide excellent homogenous blending of medicinal materials.
The LM 40's exceptional efficiency can be due to the revolutionary proprietary L.B. Bohle countercurrent process technology. This novel technique also safeguards the operator and the product from contamination during processing.
The cutting-edge LM 40 laboratory blender is ideal for R&D applications and fulfills all current GMP design, operating, and control standards. It has a compact, adaptable design.
The mixing technique is powered by an AC motor inside the machine housing to ensure optimal efficiency. The control panel has also been integrated into the machine housing for easy access.
The containers have adaptor tubes and may be readily picked up by the laboratory blender's integrated forklift pick-up system.
Due to their flexibility, square containers, drums, double-cone containers, V-shells, and other specialty containers can all be utilized for blending. In addition, the optional movable lifter ensures that all containers and dishes are readily removed.
This laboratory blender is appropriate for space-constrained applications due to its compact size, single-axis movement, and tiny footprint.
Scalable production output from 5 to 12,000 liters
The LM 40 laboratory blender may be easily scaled up to the desired production size, with results ranging from 5 to 12,000 liters. Blending findings can be transferred to a production-scale blender.
