Whether you're setting up a new flour mill, upgrading existing equipment, or optimizing a feed processing plant, choosing the right grain cleaning equipment is one of the most important decisions you'll make.
1. Know Your Grain and Impurity Profile
Before specifying any machine, you need to understand what you're cleaning and what you're removing. Different grains (wheat, corn, rice, soybean) have different densities and sizes, and the impurity mix varies by origin, harvest method and storage history.
Typical impurities include:
- Oversize: straw, stalks, cobs, large stones
- Undersize: sand, soil, small weed seeds
- Lightweight: chaff, dust, empty husks
- Heavy: stones, metal fragments, dense seeds
2. Define Your Target Throughput
Grain cleaning equipment is rated by throughput (t/h). Always spec your cleaner at 110–120% of your actual requirement to account for peak loads and future capacity growth. A machine running at 70% capacity lasts significantly longer than one at 100%.
3. Consider the Cleaning Steps Required
Most operations require at minimum a pre-cleaner to remove large debris, followed by a fine cleaner to separate by size and weight. Destoning is essential if you're feeding a hammer mill or roller mill — stones cause enormous damage and downtime. Our combined cleaners perform all three functions in a single pass.
4. Factor in Dust and Noise
Grain cleaning generates significant dust. Ensure your selected machine has sealed aspiration channels, connects to a properly sized aspiration system, and meets local environmental and workplace safety regulations.
