Gold mining is the science technology and business of discovering gold removing it and selling it on the market The gold milling process consisted of three general steps 1 Sorting the ore by size 2 Crushing the rock Larger ore fragments were pulverized or crushed in the crusher The fine ore was fed by conveyer belt to a ball
The first step in the mining and processing of nearly any mineral ore is comminution Since the oil embargo of 1979 the mining companies have been striving to reduce energy consumption and costs The first serious step was the introduction of in pit crushing in the early 1980s With in pit crushing accepted as a standard design mode the energy saving emphasis turned to

A jaw crusher is a robust essential and rugged crusher used primarily in mining and construction for the initial crushing of large rocks and ore Positioned at the start of the crushing process it uses compressive force between two jaw plates to break down large materials into smaller manageable pieces
Every jaw crusher diagram is a window to the soul of this rugged machine providing vital insights to the components that make up its robust design At the heart lies two pivotal plates the fixed jaw and the movable jaw The fixed jaw as the name suggests remains stationary and serves as the backbone for the crushing process
