Model. VAL-1500 x 6 – 2 x 3. Vertical Aspiration Leg 1500 mm wide, with six layers of screens, which consists of a double deck with 3 layers of screens in each deck.
Machine details are;
The Feed hopper is near the top of the machine at a convenient auger height.
The Aspiration system has a large capacity fan with a 7.5 KW motor. This fan will lift the dust, weed seeds, light and pinched grain. This material is collected in a cyclone. In the bottom of the cyclone is a rotary valve which drops the material onto a tray. This tray conveys the material to the bottom of the screening deck where it is combined with the small screening grain.
The Screening deck has two electric vibrator motors with six layers of screens. The vibrators give the deck a small orbital motion. Under each layer of screens there is a tray which holds rubber balls. The bouncing of these balls hits the underside of the screens removing the lodged grain in the screens. Each layer of screens is made up of two pieces 1500 mm x 1200 mm, giving a total screen size per layer of 1500 mm wide x 2400 mm long. By using screens with different apertures, which may be slots or round holes, it is possible to clean a large range of grains.
The screening deck can be setup with one layer of screens for scalping and two layers of screens for screening. Another option is to have two layers of screens for scalping and one layers of screens for screening.
The machine is transported on Tandem spring suspension.
The capacity of this machine is from 6 – 25 Tonnes per hour.
It is very easy to operate and the adjustments are simple and responsive.
