Lead zinc aluminum industry in China is a non-ferrous metals, copper, lead and zinc in four varieties are the most promising varieties, so that the lead-zinc importance of self-evident. So what equipment is needed in the process of lead-zinc ore dressing ? Let's take a brief look at this article.
In general, lead-zinc ore dressing equipment can be divided into crushing equipment, grinding equipment , classification equipment , magnetic separation equipment , flotation equipment and drying equipment. So how do these devices work together in a coordinated manner?
The lead-zinc ore that has been mined is firstly crushed by a jaw crusher. After being crushed to a reasonable fineness, it is evenly fed into the ball mill through a hoist and a feeder, and the ore is crushed and ground by a ball mill. The ore fines ground by the ball mill enter the next process: classification. The spiral classifier cleans and classifies the ore mixture by the principle that the specific gravity of the solid particles is different and the rate of precipitation in the liquid is different.
The washed and graded mineral mixture separates the magnetic material in the mixture by magnetic force and mechanical force when passing through the magnetic separator because of the different specific magnetic susceptibilities of the various minerals. The mineral particles that have been initially separated by the magnetic separator are sent to the flotation machine, and different drugs are added according to different mineral characteristics, so that the desired minerals are separated from other substances. After the desired minerals are separated, because they contain a large amount of water, they must be initially concentrated by a thickener and then dried by a dryer to obtain a dry lead-zinc ore.
Galvanized steel, refers to the ordinary carbon construction steel through galvanized processing can effectively prevent steel corrosion and rust so as to extend the service life of the steel, including galvanized electricity galvanized and hot dip galvanized.
Commonly used in building exterior wall, such as glass curtain wall, marble curtain wall, aluminum curtain wall do column and bear force material, or used in outdoor telecommunication tower, highway and other outdoor construction steel is called galvanizing steel, among which galvanizing divides electricity galvanizing and hot dip galvanizing.
