Gold Crushing Operation

Gold milling begins when ore material from the mine is reduced in particle size by crushing and grinding. Crushing is crucial stage in gold benefication process. According to end products requirements, gold crushing is generally processed in three steps: primary crushing, secondary crushing and tertiary crushing.

A primary crusher, such as a jaw crusher, is used to reduce ore into particles less than 150 mm in diameter. Impact crusher and cone crusher are often used in secondary and tertiary crushing process. Generally, crushing continues using a cone crusher and a vibrating screen until the ore is less than 19 mm. Crushing in jaw and cone crushers is a dry process, with water spray applied only to control dust.

Gold Ore Processing Plant

Gold crushing is the first stage in the comminution process. This is usually a dry operation, which involves breaking down the ore by compressing it against rigid surfaces or by impacting it against hard surfaces in a controlled motion flow.

Crushing process step prepares the gold ore for further grinding or for feeding directly to the classification or concentration separation stages. We provide high quality gold crusher equipment. The popular gold crusher machine includes the following types:

  • 1. jaw crushers
  • 2. cone crushers
  • 3. roll crushers
  • 4. impact crushers
