Zinc ore is important for the production and development of zinc as an important raw material for the non-ferrous metal zinc. From zinc ore to zinc metal, it needs to go through the production process of crushing, grinding and beneficiation. Huashengming Heavy Industry introduces the crushing process of zinc ore and the configuration of crushing production line!

Three-stage crushing process:

Zinc ore crushing usually adopts three-stage crushing process, according to the ore hardness (Platts hardness coefficient f=8-12) and particle size requirements, divided into coarse crushing, medium and fine crushing, fine crushing three stages

Coarse crushing stage

Jaw Crusher

Equipment: Jaw Crusher
Function: Crushing raw ore (≤700mm) to ≤200mm.
Advantage: deep cavity optimisation design, large capacity (90-1100t/h), strong wear resistance, suitable for high hardness ores.

Middle and fine crushing stage

Impact crusher

Equipment selection: Impact crusher
Function: further crushing to ≤50mm, improve crushing ratio.
Advantage: Suitable for low and medium hardness materials (e.g. limestone), good grain size and low energy consumption.

Fine crushing stage

Roll Crusher

Equipment Selection: Roll Crusher
Function: Crush the ore to ≤12mm (into the grinding size), or with closed-circuit screening to achieve a finer particle size.
Advantage: Hydraulic adjustment of crushing, adjustable mode, suitable for high-precision crushing (output 20-550t/h).

The above is the introduction of zinc ore crushing equipment and production line configuration, you can leave a message at any time if you want to know the related equipment and configuration.
