From Cotton Seed Hull to Briquettes: Continuous Production Line Creates New Profit

Cotton ginning plants generate massive volumes of cotton seed hull as a byproduct after seed separation. Traditional disposal options deliver little economic return for cotton processors. Dingli Group's integrated briquette production line unlocks commercial value for this abundant agricultural waste.

The complete line integrates feeding, continuous rotary drum carbonization, sealed cooling, pulverizing and briquette extrusion. Running under sealed oxygen limited conditions, the system achieves uniform carbonization with automated feeding and discharge for round the clock continuous production.

Pyrolysis generated combustible gas is captured, purified and recycled as internal heat source. This closed loop energy system cuts external fuel consumption, while centralized flue gas treatment helps finished briquettes satisfy strict international environmental standards for export trade.

Dingli Group delivers reliable turn key production lines for global clients, advancing low carbon solid fuel transformation and exporting practical Chinese technical solutions for global circular agricultural waste recycling.
