含有磨蚀性和润滑性添加剂的粒状磷酸盐产品

Granulated phosphate product containing abrasivity and lubricity additives
Abstract:
A granulated phosphate composition that provides sufficient nutritional value as well as enhanced pelleting benefits, such as abrasiveness and lubricity, compared to other granulated phosphate feed products. The granulated phosphate composition includes a phosphate source, such as monocalcium phosphate, mono-dicalcium phosphate, or dicalcium phosphate, and one or more additives such as lubricity and abrasivity additives. The lubricity additive can include a sodium additive that lubricates the die during a feed milling or pelleting process. The abrasivity additive can include silica or sand that scours the die during the pelleting process. The increased lubricity and abrasivity attributes of the composition benefits die throughput and efficiency in the pelleting process, without compromising nutritional value in the final feed product.
