The crushing process of concrete is nearly the same as stone crushing. Firstly, we choose the usable materials and transmit them with the stone vibrating feeder. Then vibrating feeder pours them into primary portable concrete crusher. Then products of primary concrete crusher get crushed by secondary mobile concrete crusher. Secondary concrete crusher crushes stones into smaller size and usually they can get used. But more often the products of secondary concrete crusher get screened by vibrating screen and whose can fit the requirement will leave this process and become the final product and the others will go back to secondary concrete crusher or even primary crusher to get crushed. Finally, concrete all become the right products we need. Tertiary concrete crusher is usually used in special crushing process. Tertiary concrete crusher will process stones into much smaller size than secondary crusher. We usually choose mobile crusher or portable concrete crusher is this process. Because it is really convenient to use mobile concrete crusher or portable concrete crusher in this process.

It is reported that the huge market in China and the integration policy of the coal crusher machine industry released recently is promoting the mining machinery manufacturers to make an investment.According to the survey conducted by the special survey center of Chinese market economy, the newly built building-used ore mines of limestone mine, granite mine and fluorite mine approved by the government this year reaches 200. This survey also shows that the demands for all kinds of mining machines driven by a newly built ore mine whose investment is less 10 million can reach about 100. For this reason, the demand produced by the infrastructure construction in China is a main promoting factor. From 2008 to 2009, Chinese market has surpassed the North American market and becomes the largest market in the world that sells the most mining machines and in 2010, the output of mining machinery in China may accounts for 50% of the total output in the whole world.

With the advance of the merger and reorganization of coal enterprises, the average size of the coal mines will gradually increase and low-end products will be eliminated, which will produce new demands for high-end and intelligent coal exploitation equipment and large-sized washing and dressing equipment and promote scientific and technological progress in this industry and the growth of the leading enterprises.

Some experts say that many mining machinery companies in our country still linger about the low-end market. Take crushing equipment as an example, the market shares of independent brands accounts for less than 30%, and most of them concentrate in the low-end market and the independent brands of medium and large excavators over 20 tons are basically blank. In addition, the core spare parts of the mining machinery like hydraulic component, engine, controlling component and drive system still rely on export, so that the manufacturing companies that can successfully realize export substitution will have great market opportunities.

For of gold ore mining, a full set of gold ore dressing equipment is very important, the configuration of gold ore dressing equipment directly affects gold crusher ratio and gold utilization rate. If we want to increase the mining ratio of gold ores and decrease the waste of gold mineral resources, the gold ore talings processing equipment or gold tailings processing production line are necessary.

In gold ore dressing production line, there is usually a high gold content in the tailings, therefore, improving the tailings recovery rate can be a very effective way to promote the utilization rate of gold resources. While, how can we effectively improve the recovery rate of gold ore tailings?

  • 1. Improve the gold ore dressing process. Improve and develop gold ore dressing process by making full use of the rough concentrate, innovating new grinding technology, choosing flotation reagents with good selectivity, improving the grade of gold concentrate, etc.
  • 2. Raise the automation level of mineral processing equipment. There are many means to improve equipment automation level and recovery rate of preparation equipment, such as constant feed ratio of the grinding system, water level control, automatic control on the flotation pulp pH value, online monitoring, computer analysis and intelligent computer control.
  • 3. Finally, improve the technical and economic indexes of gold mineral processing equipment. It is for large-scale gold ore dressing equipment. Gold ore dressing plants should use appropriate workshop corresponding to the scale of the large sized gold ore dressing equipment as far as possible, which contributes to realizing the automation control on the production process of mineral processing equipment, increasing gold recovery rate, reducing energy consumption and costs, and improving economic benefits.

The energy consumption for conveying the tailings in the ore beneficiation plant is very high. Since the tailings have to be timely transported to the tailing dam, the pulp pump must run without stop, which directly increases the energy consumption for tailings transportation and improves the production fees. For this reason, on the condition that the pump station, pipeline and head are all fixed, it is advisable to use the variable-frequency governor to change the rotary speed of the machine unit and change the parameters of the impeller to reform the old pump. Using the variable-frequency tailing conveying pump can realize high-density conveyance or constant-density conveyance, which will effectively reduce energy consumption and production cost.

With the constant development of science and technology, the ore dressing technology and SBM crusher and processing such as flotation machine, magnetic separator and ball mill are also constantly making progress and developing. The ore dressing industry in our country provides good development platform to promote the improvement of the taste of the dressing materials in order to provide various kinds of excellent mineral products for other domestic industries.
