Three Dimensional Product Movement for Better Mixing

Plough Share Mixer

Plough Share mixers operate on the concept of a fluid bed with three-dimensional product movement that is mechanically generated. The mixer consists of a cylindrical mixing vessel containing plough or paddle shaped mixing elements mounted on a horizontal shaft installed along the central axis of the mixing vessel. The mixing elements are designed to lift and separate the product within the vessel. The number of ploughs / paddles, their spacing, and the speed of rotation all contribute to degree of fluidization. Plough Share mixer provides intense mixing within short mixing times.

A drive system comprising of a motor, gearbox and couplings drives the plough shaft. A sealing arrangement is provided for the area where the shaft exits the container to ensure that material does not travel from the container to the outside and vice versa. For injecting liquid into the material, liquid spray systems can be provided. For applications requiring lumps to be broken down or when the mixer is to be used for wet granulation, plough mixers can be fitted with high-speed chopper units. In the lower portion of the mixing vessel, single or multiple choppers are mounted. It is popular to use the tulip-shaped chopper and x-mass tree chopper variants.

Materials are charged through nozzles located at the top of the cylindrical mixing vessel. The working volume ranges from 30 percent to 70 percent of the total vessel volume. The agitator shaft rotates at high peripheral speeds of more than 200 metres per minute to produce a whirling, three-dimensional fluidized product movement. The turbulence and material movement within the mixer vessel prevents formation of dead-spots or low-movement zones and ensures intense and homogenous mixing in short time.

The material is discharged through a discharge nozzle located at the lower end of the container after completion of mixing. In order to prevent any dead pockets inside the mixer, flush bottom discharge valves are recommended. These valves can be operated manually, pneumatically or hydraulically. For cleaning and inspection access, wide hinged side doors are provided. Plough mixers provide excellent solutions for mixing materials like powders, powders with liquids, heavy pastes and putties. In a short period of time, homogeneous mixing of materials of different densities, flow properties, particle sizes and structures is achieved. It is possible to combine ratios as high as 1:20,000, with 95 to 98 percent homogeneity, in under 5 minutes. The plough share mixer is capable of handling up to 600,000 centipoises of viscosity. The specific power for the mixer drive generally ranges from 30 to 40 kW/m3, depending on the properties of the materials to be mixed. Plough mixers can be built to operate in both batch and continuous modes.
