Discontinuous and continuous birotor mixers with blades 

Discontinuous birotor mixer with blades

The BRP double shaft mixer with blades is a continuous mixer with two parallel tanks, each fitted with blades which promote a homogeneous mixing regardless of the particle size and density.
The intensive mixing action ensures, even with delicate or very brittle products, an optimal process without the formation of fine particles. The mixer can be started under full load.

The BRP batch mixer is used for dry solids (powders, granules, short fibers), dry solids + liquids (moistening, granulating, coating), as well as liquid and low-viscosity pastes.

Main advantages

  • maximum homogeneity of the mixture
  • Short mixing time (5-30 sec.)
  • Gentle handling of the material
  • Shorter discharge time due to double discharge mouth
  • Low residue (0-5,5% of the volume)
  • Easy cleaning
 

Operating mode

The horizontal rotors, which rotate in opposite directions, create a fluidization zone which ensures accurate mixture of products. The fluidization zone is generated by mixing the two technologies, the first in turbulence and the second in conveying. In these fluidized zones, powders and granules are dispersed optimally within a very short time. The double shaft mixer with blades BRP guarantees high performance in terms of homogeneity and mixing speed.

Continuous birotor mixer with blades

PALAMATIC PROCESS continuous mixer with overlapping blades is ideal for homogenization and mixing of dry or wet materials applications. 
These machines, of simple and robust design, are fitted with double parallel rotors and ensure the mixture of two or more materials but also their conveying during the mixing process. These mixers are ideal to carry out neutralization of sludge with lime, moistening of dust, extinction of quicklime etc...

Main advantages

  • Homogeneous conveying and mixing
  • Modular system for minimum maintenance costs
  • Powers adapted to demand
  • Adjustable blades with or without wear protection
  • Self-cleaning rotors thanks to overlapping blades
 

Operating mode 

Double shaft mixers with blades BRPC are adapted to dust mixing, granulation, neutralization of sludge and moistening of dust, ash or sludge. The overlapping of the blades and the adjustment of their inclination ensure a very good adaptation to the products to be mixed. The continuous mixer is made of a tank which contains two parallel rotors fitted with blades which intersect during operation thus covering the entire surface of the trough. The start of the mixer is also possible when full loaded.
