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 unit is provided with a guard rail with electrical safety to prevent the operator from accessing it when in operation. If anyone should gain access to the unit, for safety reasons, the operation will cease.

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 unit is manufactured in AISI 316 (EN 14404) quality for all parts in contact with the product and AISI 304 (EN 14301) for the supports and the rest of the equipment. The internal and external surfaces have a bright polished finish.
Due to the polished surface and absence of edges or corners, the unit can be easily cleaned either manually or automatically with CIP system.
The unit incorporates a guard rail with electrical safety, according to EC safety standards.
The motors and electrical panels are available in standard or ATEX protection.
It allows the addition of liquid additives depending on the product to be mixed. Normally, these liquids are added in spray form in order to affect the largest number of particles in the mixture, thereby increasing efficiency.
The system offers a clear added value. The unit’s large production capacity, the high quality of the resulting mixture, and the low energy and maintenance costs directly contribute to an increase in profitability.
On request, the loading and discharge systems can be automated with a butterfly valve with pneumatic dosing system.
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.

This unit allows the incorporation of a liquid spray system to introduce liquids in spray form during the process. The injector is connected to the spray nozzles by means of a rotary system and is fed with additives from a pressurized tank or by means of a variable displacement pump at constant pressure.
The automatic stop positions are: loading, discharging, and sampling. Before stopping at one of these three positions, the system performs a cycle which slows down the mixer in order to reach the stopping position with the highest possible accuracy and remains halted at that point.
The unit can be equipped with an automated loading system for introducing powders and granules into the blender body by means of a vacuum unit with self-cleaning hoses. It prevents creation of dust.
The skid can also be provided with a complete monoblock vacuum unit with liquid ring pump.
It is possible to install an automated vacuum discharge system. It includes a product receiving hopper with an automated
self-cleaning filter; as well as a control panel for the unit.
The loading/discharge can be carried out with pneumatically actuated retractable hermetic bellows. This system and the vacuum loading/discharge can be combined.
