Lead-Zinc Ore Grinding Mill
Lead-zinc ores are mineral deposits rich in lead and zinc, primarily used for the extraction of these two metals. Lead and zinc have a wide range of applications, serving sectors such as the electrical, mechanical, military, metallurgical, chemical, light industrial, and pharmaceutical industries. Furthermore, lead is also extensively used in fields including the nuclear and petroleum industries.
Applications
The grinding process for lead-zinc ore is generally categorized into three types: coarse powder processing (0–3 mm), fine powder processing (20–400 mesh), and ultrafine powder deep processing (400–3250 mesh). The specific production process required varies depending on the material, the desired specifications, and the intended application; therefore, a flexible approach is necessary.

Large pieces of lead-zinc ore are crushed by a crusher until they reach a fineness (15mm–50mm) suitable for entry into a grinding mill.
The crushed lead-zinc ore fragments are transported via an elevator to a storage hopper, from which they are fed uniformly and at a controlled rate into the grinding chamber of the mill.
For fine powder production, equipment such as the LM Vertical Roller Mill, MTW European-style Mill, or 6X Intelligent European-style Mill (featuring thin-oil lubrication) is typically used. For ultrafine powder, the LUM Ultrafine Vertical Mill or MW Ring-Roller Micro-powder Mill is preferred. For coarse powder, the CM European-style Coarse Powder Mill or a direct-flow centrifugal mill is used.
The ground material is processed through a powder classifier. Particles that do not meet the required fineness are separated and returned to the main mill for further grinding.
Particles that meet the required fineness are carried by an airflow through ducts into a dust collector, where they are separated and gathered. The collected finished powder is then transported from the discharge outlet to a finished-product silo, from where it is either loaded into bulk tanker trucks or processed through an automatic bagging machine.
