MBC Double Cone Blender

The main body of the blender consists of two cone-shaped sections welded at their bases to a central cylindrical section. The axis of rotation is perpendicular to the cone axis and passes through the cylindrical section. The driving motor is located at one of the two lateral supports holding the blender body.

The solids are introduced into the blender through the loading aperture. In this type of blender, mixing takes place axially, as a result of the powder moving through the different sections. Mixing is thorough but it depends on the rotating speed.

The mixture is discharged through a hermetically closing butterfly valve which can be operated manually or automatically.
The skid has an electrically secured safety perimeter guard to prevent operators from gaining access during use. In the event of accidental access, for safety reasons the process will be stopped.

The series consists of 6 models with a total capacity of 160 to 4200 litres and a useful capacity of 65% of the total.
This blender is especially designed for sensitive mixtures with risk of breakage where the generation of dusts is to be avoided. Mixing times vary between 5 and 20 minutes depending on the mixture.
There are two apertures: the loading and cleaning aperture, and the discharge opening, which incorporates a butterfly valve thatcan be operated automatically or manually.
The apertures are sealed hermetically in order to avoid contamination from the outside during the mixing process.
The interior of the blender incorporates a cone mounted on the pivot axis on both sides. This system eliminates the formation of dead spaces and facilitates gravity discharge.

The skid is manufactured in AISI 316 (EN 14404) for all parts in contact with the product and AISI 304 (EN14301) for the rest of the equipment. Standard finish is Ra<0.8 on the inside and 2B on the outside.
Easy to clean, both manually and with an automatic CIP system, thanks to its hygienic design and the absence of entrapment areas.
It has perimeter safety protection with a door, is manufactured in accordance to EC safety standards.

The automatic stop positions are: loading, unloading and sampling. Before stopping in one of the above three positions, it performs a cycle that will slow down the mixer so that it can be accurately positioned and brought to a stop.
This equipment has been designed -in contrast to the “V”-type blender- to handle mixtures of granulated products and powders, or mixtures of products with high and different densities, with a loading of 65% of the total capacity of the equipment, unlike the 50% loading in a “V”-type blender, which handles mixtures of powders with the same bulk density.
