Blending Systems for the
Pharmaceutical Industry

Container Blenders – PM

In the production of pharmaceutical solids, the homogeneity of the mixture produced by container blenders is a critical process step. An even distribution of all components in the mixture is the goal of this process.

L.B. Bohle has produced container blenders for pharmaceutical production since 1987. To date,
thousands of container blenders have been built, and every day a wide variety of several blending systems are used worldwide in the production lines of pharmaceutical companies and contract manufacturers.

With the successful mix of idea and construction, L.B. Bohle is one of the leading companies on the global market in the field of container mixers for the pharmaceutical industry. It doesn’t matter whether it is a laboratory mixer, a container blender, or a system with a container capacity of up to 12,000 liters.

Blending with the Container Blender
by L.B. Bohle

The product portfolio of our container blenders is designed to be very diverse thanks to the high flexibility in the areas of design and production. The container blenders from L.B. Bohle can be used in all conceivable production scenarios in the pharmaceutical industry. It doesn’t matter whether you use round or square containers in your production, as there are numerous pick-up systems for mixers. We offer the container blenders you need for your manufacturing process.

Container blenders guarantee homogeneous mixing

The blending elements inside the container lid allow all Bohle blending systems to achieve the homogeneous mixing of dry powder batches. The blending procedure is scalable for volumes between four to 12,000 liters.

For highest flexibility, blending containers or mixing containers with different capacities can be used. The Bohle blending process guarantees the effective mixing of batches between 20 – 85 % and with densities between 0.2 – 1.2 kg/l.

PM Pharma Blender – stationary blending device with the following components:

  1. Container blender machine body with load suspension device
  2. Electrical switch cabinet integrated in machine body
  3. A separate installation is available upon request
  4. Separate operator panel (15“ Touch Panel), Printer/PDF print option
  5. Safety light barrier or laser scanner available as an option

The blending operation is a fully closed process. For filling, each container comes with an inner lid. In addition, the blender can also be used as a milling station for the transport from container to container.

High flexibility thanks to a wide range of different container adaptations

L.B. Bohle offers a wide range of pick-up systems for its blending systems

  1. Standard arm connection and clamp
  2. Round forks on the lifting arm
  3. Lifting arm with eccentric clamp, power clamp and hydraulic clamp

Multiple processes in one system – blending, optionally with chopping and liquid addition

  1. Closed system, therefore optimal for containment applications
  2. No cleaning required between batches
  3. Gentle product movement
  4. Rotates up to 6rpm
  5. Optional speed increase possible after technical clarification
  6. Blending elements in intermediate bulk container (IBC)
