Vertical spiral mill is a fine-grained grinding equipment, which is mainly used in iron ore, copper ore, molybdenum ore and some non-metallic ore industries. It is the main product to replace the traditional two-stage ball mill.

NHI is one of the main suppliers of vertical spiral mills in China. It started the research and development of vertical spiral mills in 2012. At present, it has realized the design and production capacity of product serialization and differentiation.

The vertical spiral mill produced by Fangda Group Northern Heavy Industries Group Co., Ltd. has the characteristics of energy saving, environmental protection, high efficiency, small land occupation and high information level, which is 30-50% more energy-saving than the traditional ball mill.

Recently, the 4500 HP vertical spiral mill with the largest installed power in the world was successfully offline in NHI. The energy-saving characteristics of the product have been generally recognized by the market under the background of carbon neutralization and carbon peak, which will help users reduce operating costs and continuously improve benefits.
