High quality mixing acknowledged thousands of times

The WBH Batch-Type Single Shaft Mixer is the ideal machine to obtain highest quality mixtures in perfectly reproducible batches. In the last three decades MAP has supplied thousands of mixers to a large variety of industries worldwide. Mixing tests for customers are performed in the Group’s own laboratories in currently more than fifteen countries.

WBH Horizontal Single Shaft Batch Mixers consist of a mixing drum vessel with an inlet, an outlet with discharge valve and a venting spout, a full material mixing shaft, two drum closing end plates that carry flanged end bearing assemblies complete with integrated air or gas-purged shaft seals, and a drive unit complete with power transmission.

Function :

• The WBH Horizontal Single Shaft Batch Mixer is based on the principle of mechanical fluidisation of the product.
• The particular shape, position and rotation speed of the mixing tools, creates a centrifugal vortex motion which allows the materials to be projected in a three-dimensional way and to merge with each other.
• This ensures that ingredients with different particle size and bulk density are perfectly blended and mixed with high precision within the shortest possible time.
• WBH Batch-type Mixers are used for mixing dry powders, granules or short fibres, for moistening, agglomerating or granulating the same materials, or for mixing liquids or low viscosity pastes.

Features :

• Capacity: 10 to 20,000 litres per batch
• Mixing ratio: 1/100,000
• Variation coefficient (CV): 3 ~ 5%
• Possibility of adding up to 20% of liquid
• End bearing assemblies with various types of air or nitrogen-purged shaft seals or grease sealing
• Heavy-duty mixing chamber manufactured from carbon steel, anti-wear steel or 304L / 316L stainless steel
• Stainless steel surface finishing: grit silking, mirror polishing, glass bead blasting
• Wide range of mixing tools (boxed ploughshare, toothed ploughshare, blade, toothed blade-type) available, with anti-wear coating on request

Benefits :

• No product deterioration or damage
• Low maintenance
• Durable machine
• Power rating adapted to application
• Easy cleaning and access to all internal parts of the mixer
• Mixing know-how and test facilities

Ploughshare or inclined blade-type shovel tools rotate as mixing tools in a special arrangement on the mixer shaft in a horizontal, cylindrical drum vessel. The result is a turbulence in the mix that constantly involves all the product particles in the mixing process. The formation of dead spots or slow-movement zones in the mixing drum is prevented ensuring precise mixing. In some cases, to obtain the desired mixing effect, separately driven high-speed choppers can be installed.
