Descrição

This planar rotary screen is a specialized grain cleaning machine designed to accommodate the distinct physical characteristics of wheat and corn. Wheat kernels are slender and elliptical, with ventral creases prone to trapping fine sand, dust, and light impurities; in contrast, corn kernels are larger and flatter, often mixed with cob fragments, silk, stones, and broken grains. Utilizing a gentle horizontal gyratory motion and a multi-deck screen structure, the equipment effectively removes large, small, and light impurities, delivering clean material for downstream processes such as milling, feed production, storage, and further sorting. Ideal grading results can be achieved by simply changing screens with different aperture sizes; the unit operates smoothly with low noise and offers ease of use and maintenance.

Planar Rotary Screen Working Principle

The machine is driven by an eccentric shaft and counterweight system that makes the screen body perform a horizontal planar rotary movement. This motion is gentler than strong vibration, which is important for protecting fragile wheat kernels and reducing breakage in corn.

When wheat or corn enters the feed inlet, it is evenly distributed onto the first sieve deck. Because the screen body moves in a circular path, the grain travels in a spiral and forward direction across the sieve surface. This gives the material enough time to stratify and separate.

For wheat cleaning, the upper sieve catches straw, wheat ears, strings, and large impurities, while the lower sieve removes sand, small stones, and broken kernels. For corn cleaning, the upper sieve discharges corn cobs, stalks, and large debris, while the lower sieve removes sand, fine dust, and small broken pieces. An optional aspiration connection can also remove light impurities such as dust, wheat awns, and corn silk. The cleaned wheat or corn is then discharged from the outlet for the next processing stage.

Parameter

Features

• Dual-purpose screening for wheat and corn: The planar rotary screen is configured with different sieve meshes and deck combinations to match the size and shape of wheat and corn kernels.

• Horizontal planar rotary motion: The eccentric drive creates a smooth circular movement, which helps wheat and corn stratify evenly without aggressive jumping or damage.

• Multi-layer sieve decks with quick-change screens: Upper and lower sieve frames can be changed quickly, making it easy to switch between wheat cleaning and corn cleaning.

• Enclosed dust-tight structure with aspiration outlet: The machine reduces dust escape and can be connected to a dust collection system, improving the working environment for wheat and corn processing plants.

Advantages

• High cleaning efficiency for both grains: The multi-deck design removes large impurities, small stones, sand, and light dust from wheat and corn in one continuous process.

• Gentle handling of wheat and corn: Compared with vibrating screens, the planar rotary motion reduces kernel impact, helping maintain wheat quality and lower corn breakage.

• Flexible adjustment for different grain conditions: Stroke, rotary speed, and screen mesh can be adjusted according to wheat variety, corn size, moisture content, and impurity level.

• Reliable and low-maintenance operation: The balanced drive, wear-resistant sieve frames, and anti-clogging cleaning system reduce downtime and extend service life.

Benefits

• Cleaner wheat and corn for higher final product quality: Removing impurities early helps improve flour quality in wheat mills and raises the purity of corn products in corn processing plants.

• Protection for downstream equipment: Clean wheat and corn reduce wear and blockage in destoners, magnetic separators, mills, and conveyors, lowering maintenance costs.

• Higher capacity and stable production: The efficient planar rotary screening action allows continuous operation, helping wheat and corn processing lines achieve consistent output.

• Better working environment and compliance: The enclosed design and optional dust collection help control dust when cleaning wheat and corn, creating a safer and cleaner workshop.

Conclusão

The Efficient Planar Rotary Screen For Wheat & Corn Cleaning is a reliable solution for removing large, small, and light impurities from wheat and corn. By combining gentle planar rotary motion, multi-layer sieving, adjustable screen configurations, and dust-tight construction, it helps wheat and corn processors improve grain cleanliness, protect downstream equipment, reduce maintenance, and increase overall production efficiency.
