granulating disc isa cubage measuring feeding e; it supplies materials to thenext procedure evenly and continuously; at the same time, it canbear relatively higher pressure. it is a fine powdery materialfeeder suitable for non-cohesive materials like coal powder,cement, chamotte, limestone, shale, gangue and clunch. it is widelyused in gold concentrator, coal mine, chemical plant, constructionand foundry for and even feeding. advantages of thismachine are: simple structure, easy-to-adjust and excellent inperformance. this machine is suitable for conveying of materialswith granularity less than 50mm, while it is not suitable forcohesive materials, easy-to-flow or hard-to-flowmaterials.
