Double-spiral batch mixers.
Double-spiral batch mixers are used for the preparation of homogenious mixtures from dry powdered and granulated mineral materials such as fertiliers, rubber derivatives; biological materials such as spices, and others such as polymers, bentonit. They can also be used for the averaging of the composition of batches of materials.
Mixer 4C11 ( volume 600 dm3 ) is used for mixing of suspensions, emulsions, and solutions.
Prerequisites for the components for dry mixtures: particles' size of up to 10 mm, content of moisture of up to 5 %, for liquid materials viscosity of up to 100 cSt.
The central part of the mixer consists of single- or double spirals, placed on a vertical shaft which rotates.
The components are loaded into the mixer in order to achieve a homogeneous composition of the mixture. The material if offloaded from the mixer and the process may be repeated on another batch of material.
The non-uniformity of prepared mixtures does not exceed 2 - 3 %.
Mixing time up to 10-20 min.
