Grain cannon with attached air classifier precleaner
Gruber Mobile Precleaner Combination Types VRK / VRKE
The Gruber Grain Cleaning Combination Type VKR or with increased discharge height VRKE, is suitable for optimal pre-cleaning at the grain intake. The chassis with castors makes the unit easy to operate by one person.
The Gruber VRK / VRKE series of grain precleaners are used for powerful pre-cleaning of grain, maize and other cereals from dust, chaff and other light foreign bodies. It eliminates up to 85% of the foreign matter in the grain. This means a qualitative improvement of the stored goods. These grain precleaners work according to the air classifier principle and are suitable for separating those parts that are lighter than grain (e.g. dust, husks, small grains, etc.). The air classifier fan can be adjusted to the required air output, which depends on the type of grain, among other things. The air flow separates the lighter parts in the cleaning cone and thus ensures a good cleaning effect.

Mobile, compact cleaning units with 5 different conveying and cleaning capacities and 3 different discharge heights. The air classifier precleaner fed by the grain cannon is suitable for separating parts that are lighter than grain e.g. dust, husks, small grains, etc.
The air volume and thus the degree of cleaning can be changed by means of a throttle valve at the outlet of the cleaner fan or by means of electronic speed control of the fan motor (frequency converter).
The grain is fed through the inlet spout on the side of the cleaning cone. The rotating distribution wheel distributes the grain optimally, cleans it and feeds it into the collection funnel.
In the attached dust cyclone, the clean-out is separated from the air and can be bagged, for example.
