Agricultural Rotary Grain Classifier Separator

How the rotary grain classifier separator works

A motor and V-belt at the base drive the sieve box in a rotary motion. The top deck removes large impurities such as straw, cobs and stones, while the bottom deck lets sand and small seeds fall through. Clean grain leaves between the two decks. Rubber balls bounce under each screen and knock out trapped kernels, so there is no blockage of material in the sieve perforation.

The maker lists these points for the model:

• Suits pre cleaning and fine cleaning of all types of grain
• Double deck system
• Low maintenance

Across the machine type, designs are typically motor driven, continuous rotary operation, with a rotating perforated cylinder/reel classifier and a perforated steel cylinder, steel frame.

Model sizes

The listed models share a length of 2900 mm and a height of 1520 mm:

• 2900x1580x1520 mm: 1.5 KW motor, 10 TPH, 2500x1200 mm screen
• 2900x1850x1520 mm: 1.5 KW motor, 15 TPH, 2500x1500 mm screen
• 2900x2150x1520 mm: 2.2 KW motor, 20 TPH, 2500x1800 mm screen

Rated output depends on the grain and on how clean it is at intake, so we confirm the right size for your crop at quotation.

Buying notes

Buyers usually send us the crop, the hourly flow and their site voltage, and we match the sieve hole sizes to the grain. A grill type magnetic separator ahead of the cleaner protects it from tramp iron, and a destoner machine after it removes stones of grain size.

We quote on EXW, FOB, CFR or CIF terms and ship to Nigeria, Kenya, Ghana and many tender buyers across Africa. See our shipping, Incoterms and export documents page for the process. Warranty follows manufacturer terms confirmed at enquiry, and the FAO sustainable agricultural mechanization pages offer wider context on post-harvest cleaning.
