Product Description

50tph slag grinding plant
Our vertical slag mill is typically designed to deal with industrial waste residues generated by the blast-furnace ironmaking. Due to its high physical and chemical activity, and potential hydraulicity, the slag has been widely as admixture matters in the cement industry. And the slag can replace the cement in the concrete to improve the quality and durability of the concrete.
Here in Jiangsu Pengfei Group Co., Ltd, our vertical slag mill has features of high grinding efficiency, strong dry capacity, easy adjustment, low noises, low electricity consumption, simple process flow, little abrasion, and so on.
