For feed mills, oilseed meal plants and grain processors packing 50–70 kg (110–154 lb) bags. The machine feeds, opens, weighs, fills, closes and labels each bag at 540–650 bags per hour (tested with soybean meal), and brings bagging labor from 5–6 workers to one supervisor.

The rate was measured with soybean meal. Other products and bag sizes change it, so tell us both and we will confirm.

Is the QZB-500B1 the right fit?

Good fit

Soybean, canola, sunflower and cottonseed meal plants
Feed mills: poultry, cattle, fish and pig feed, pellets
Rice and grain processors with heavy bags
Fertilizer, plastic pellet, sand, cement and salt packers
Plants using open-mouth woven, double-layer laminated or PE composite bags
