What Kind Of Grinding Equipment Is Needed For The Reuse Of Abandoned Lead Zinc Tailings?

According to the national annual report on prevention and control of solid waste pollution in large and medium-sized cities issued by the Ministry of ecological environment of China, the annual output of bulk industrial solid waste in China is 3.067 billion tons, of which the tailings of lead-zinc mine also accounts for a high proportion of industrial tailings.

The reuse of lead-zinc tailings is similar to that of iron, most of which are grinded and screened by magnetic separator. What is the price of the lead zinc mine tailings grinding mill?

Lead zinc mine tailings grinding mill

What kind of machine is used to grind lead-zinc tailings? There are many kinds of lead-zinc tailings recycling equipment in the market. HC series Raymond mill and HLM series vertical mill are popular all the time. They can be divided into several models according to different needs of users. Customers can choose according to their own needs.

HC series Raymond Mill

[Performance advantages]：The mill is a new generation of traditional mill equipment. It is widely used, easy to operate, easy to maintain, stable performance, cost-effective, the output is 30% - 40% higher than the traditional Raymond mill, is an economic and practical grinding equipment.

      [Application material]：It has high yield and high efficiency grinding ability for all kinds of non-metallic mineral materials with Mohs hardness less than 7 and humidity less than 6%. For example, talc, calcite, calcium carbonate, dolomite, potassium feldspar, bentonite, kaolin, graphite, carbon, fluorite, brucite and other grinding effect is good.

HLM series vertical roller mill

[Feed material particles]：0-50mm

　　[Moisture content of feed material]：＜15%

　　[Product moisture]：≤1-6%

　　[Capacity]：5-700t/h

　　[Finished product fineness]：22-180μm

[Scope of application]：It is widely used in electric power, metallurgy, cement, chemical industry, building materials, coatings, papermaking, rubber, medicine, food and other fields of production and life.

　　[Applicable materials]：For all kinds of non-metallic mineral materials with Mohs hardness less than 7 and humidity less than 6%, it has high-yield and efficient grinding ability, such as cement raw meal, clinker, power plant desulfurization limestone powder, slag powder, manganese ore, gypsum, coal, barite, calcite, bauxite, etc.

　　[Performance advantages]：It has the advantages of high grinding efficiency, low power consumption, large feed particle size, easy adjustment of product fineness, simple equipment process, small floor area, low noise, small dust, low operation cost and low consumption of wear-resistant materials.

Reuse value of lead zinc mine tailings

The lead-zinc mine tailings recycling is mainly grinding the lead-zinc mine tailings into powder. Tailings re concentration, building materials production and mine filling are the most common lead-zinc mine tailings recycling processes.

There are sulfur, iron, barite, sericite, fluorite and other minerals in lead-zinc tailings. It uses flotation, magnetic separation and other processes to enrich sulfur. When the sulfur content reaches a certain level, it can be sent to produce sulfuric acid to realize the reuse of lead-zinc tailings. Lead, zinc, copper and other elements in the tailings of lead-zinc mine can mineralize or promote the melting of cement clinker. It can be used to produce building wallboard materials and produce economic value. At the same time, it can also achieve zero discharge of tailings. It is also a good choice for the reuse of lead-zinc mine tailings.

What is the price of the machine for reusing the tailings of lead and zinc mines?

Due to the slight difference in the use of grinding equipment for different lead-zinc tailings, the different models and different prices are required, so the specific machine for the reuse of lead-zinc tailings is more than one, and the actual production is also required.
