Wheat Seed Vibration Grading Machine

Wheat Seed Vibration Grading Machine

The Wheat Seed Vibration Grading Machine from Shijiazhuang Xinlu Technology Co., Ltd. utilizes oscillating sieves and aerodynamic principles to classify wheat seeds based on size and density, critical for achieving uniform grading required for seeding and commercial sales.

The machine employs electromagnetic vibratory feeders to ensure consistent material flow onto inclined sieves. Multi-layer screens (3–12 layers, depending on model) segregate seeds into predefined size categories. For wheat, typical sieve apertures range from 2.0mm to 3.5mm to separate large, medium, and small kernels. Eccentric gear mechanisms generate adjustable vibration frequencies (800–1500 RPM), enabling precise control over material traversal speed and separation accuracy. Simultaneously, aspiration systems remove lightweight impurities like chaff and broken seeds through controlled airflow.

Models such as the 5XFJ series feature quick-release sieve frames,
allowing operators to switch screen configurations within minutes. The machine’s capacities range from 7.5 to 30 tons per hour, with power consumption between 1.1 kW and 4.5 kW. High-capacity variants include double-screen boxes for parallel processing.

Technical advancements include:

• Rubber ball sieve cleaners preventing mesh blockage.

• Frequency converters enabling stepless adjustment of vibration intensity.

• Low-noise fans (<75 dB) maintaining operator comfort.

• Stainless steel construction meeting food-grade hygiene standards.

This equipment is ideal for seed treatment centers and grain depots. It ensures graded wheat seeds with size consistency exceeding 97%, directly contributing to improved sowing efficiency and crop yield.
