PREAMBLE TO THE DESCRIPTION
The following specification describes the invention


This invention relates to a dual grinding mechanism in mixer grinder to facilitate two different mixing facility separately
Various kinds of mixer grinders are available in the prior art, some are with jar cover and some are without. Usually, during operation of mixer grinder while mixing or grinding something, user need to wait for grinding the other material, if both the materials are of different kinds for example, dry spices (dry) and chutney (wet), and he needs washing and then drying of jar for further mixing or grinding.
In one of the prior art patents no WO 2009/035353 discloses a grinder with double forced movement of the grinding medium. They provided chambers having a vibrator and drum rotator for grinding. Also polish patent no P.359118 comprises a drum which is supported on bearings at the input pivot on one side and outlet element on the other side. The supporting structure of the grinder is placed on six vibrators that are mounted on the combined footing. The drum comprises three circular chambers.
An object of the invention is to provide a dual Rotary Mechanism in Mixer grinder felicitate two chambers /jar for mixing and grinding separately at time.
Another object of the invention is to provide a dual Rotary Mechanism in Mixer grinder which is cost effective in terms of electricity and time consumption.
Yet another object of the invention is to provide a dual Rotary Mechanism in Mixer grinder which can increase the productivity of the mixing and grinding.
