PAWLICA - Model RUV -Grain Pre-Cleaner
The universal grain pre-cleaner RUV increases the cost-effectiveness of the pre-cleaning process, eventually the final cleaning of cereals, legumes, and granular substrates. It is a single screen design with switching flaps. During the reception, it is possible to use the high performance in pre-cleaning and after changing the sieves, it is possible to perform the final fine cleaning before shipping. Their significant advantage is their considerable adaptability to a large range of materials and their high performance and durability.
- output from 100 t/h to 600 t/h
- 4 air handling variants
- emissions up to 10 mg/m3 air with filter
- three screens in a row with a length of 3 m
- rotary movement of screens
- possibility to adjust the outlets by means of integrated flaps
- provides high pre-cleaning performance, suitable for second
- final cleaning on dispatch
Grain sorting into up to four fractions
The RUV pre-cleaners have manually adjustable distribution valves that allow sorting the cleaned material into up to four fractions according to the sieve setting: quality 1, quality 2 (fractions), overflow over the pre-screen and dust. The overflow and dust fractions are combined in a dust chamber. By means of manual or pneumatic flaps, they can be combined or separated very quickly.
A system of manually or automatically operated distribution valves of the RUV grain pre-cleaners feeds the cleaned material to the individual sections of the screens (3 pieces per 1 tier). The sufficiently sized air handling of these pre-cleaners, together with the air quantity control, allows handling wetter materials with a significant proportion of undesirable impurities. The air cleaning system can be selected from four variants.
- inlet aspiration
- outlet aspiration
- inlet recirculation chamber
- Combination of inlet recirculation chamber with outlet material aspiration
The recirculation aspiration chamber reduces energy consumption and the amount of air leaving the environment. A cyclone in combination with a turnstile is installed to reduce dust at the outlet. For extreme dust reduction, textile filtration can be used in RUV pre-cleaners with output air emissions up to 10 mg/m3.?
