Grain Sifter Machine
A grain sifter machine helps remove unwanted particles and separate grains by size during grain processing. It can be used for wheat, corn, rice, soybean, seeds and other dry granular materials.
For grain processors, flour mills, feed plants and food processing facilities, screening is often one of the first steps before milling, grinding, packing or further processing. The right screening equipment can remove oversized particles, fine impurities and foreign materials while keeping the main product moving steadily through the production line.
Henan Precision Screening Machinery provides vibrating screening equipment for different grain processing requirements, with screen size, deck configuration, material and discharge design available according to the application.
What Is a Grain Sifter Machine?
A grain sifter machine is screening equipment used to separate grains and other granular materials according to particle size.
Depending on the process, the machine can perform several jobs:
- Removing large impurities from incoming grain
- Separating fine particles and dust
- Grading grains into different size ranges
- Removing undersized or broken particles
- Screening grain after crushing or milling
- Preparing material for downstream processing
Different grain plants have different screening requirements. Wheat cleaning before milling, for example, may require a different screening setup from seed grading or powdered grain products. Screen opening, machine type, number of decks and feeding method should therefore be selected according to the material and process.
Grain Materials We Can Screen
Our screening machines can be configured for a range of dry granular materials, including:
- Wheat
- Corn / Maize
- Rice
- Soybeans
- Barley
- Oats
- Millet
- Sorghum
- Grain seeds
- Feed pellets
- Broken grains
- Flour and grain powder
- Other dry granular materials
For mixed or difficult-to-screen materials, we can recommend the suitable screen structure after checking the particle size, moisture content, required capacity and separation target.
Grain Screening Applications
Wheat Screening
A grain sifter machine can remove oversized particles, small impurities and unwanted foreign material from wheat before further processing. For flour mills, screening can also be used after milling to separate flour particles according to size.
Corn and Maize Screening
Corn processing may require the separation of coarse particles, fine material and foreign matter. Vibrating screening equipment can be integrated into corn processing lines for pre-cleaning or particle classification.
Rice Screening
Rice and other cereal grains can be screened to remove unwanted particles and classify material by size. The screen configuration can be adjusted according to the required separation.
Seed Grading
Different seed sizes can be separated by using different screen openings. Multi-deck screening equipment can produce several size fractions in one screening process.
Grain and Feed Processing
Screening can also be used for feed materials and other granular products to remove oversized or undersized particles before storage, packing or further processing.
How Does a Grain Sifter Machine Work?
The working principle depends on the selected screening machine.
For a vibrating sifter, the vibration motor generates a controlled vibration that moves the material across the screen surface. Particles smaller than the screen opening pass through the mesh, while larger particles remain on the screen and move toward the corresponding discharge outlet.
With multiple screening decks, one machine can separate the material into several size fractions.
The final separation result depends on several factors, including:
- Particle size distribution
- Moisture content
- Feed rate
- Screen opening
- Number of screening decks
- Material characteristics
- Required screening accuracy
For this reason, we recommend selecting the machine based on the actual grain and process conditions rather than using capacity alone.

Why Choose Our Grain Screening Equipment?
Suitable for Different Grain Sizes
Different screen openings can be selected for coarse grain cleaning, particle classification and fine screening applications.
Flexible Machine Configuration
The number of decks, screen mesh, inlet and outlet arrangement can be adjusted to suit the production line.
Enclosed Screening
For dusty grain and powder applications, an enclosed design can help reduce material loss and dust escaping into the working environment.
Easy Screen Replacement
Quick access to the screen deck makes routine screen replacement and cleaning easier.
Integration With Other Equipment
The screening machine can be combined with feeding, conveying, dust collection, milling and packing equipment to form a complete material handling system.
Grain Sifter Machine for Your Process
Choosing a grain sifter machine is not only about the required capacity. The material itself has a major effect on the screening result.
Before selecting a machine, we normally check:
- What type of grain or material needs to be screened?
- What is the particle size?
- What impurities need to be removed?
- What screening size or grading range is required?
- What is the required capacity?
- Is the material dry or slightly moist?
- How many fractions need to be separated?
- What material should the machine be made from?
Based on this information, we can recommend a suitable screening machine and screen configuration.
