The opencast coal mine has a top-down rock layer, gravel and cement, including Jurassic strata, middle sandstone, and fine sandstone and so on. The rock body owns the special features, for example slightly dense, hard, uniform structure. According to the role of the crushing condition, the different type’s rocks match the different reflection of crushing vibration. In a word, coal-bearing strata as homogeneous rock should be broken to a certain technology.
As the special nature of open-pit mining, coupled with technology is limited, surface coal mining has been restricted always. With the upgrading of mechanical equipment and technology, mining machine companies began to lucubrate on the open pit mining operation. To meet the market demand, Henan Hongxing Mining Machinery Co., Ltd. developed hydraulic drive wheeled vehicle chassis mobile quarry plant. Hongxing mobile crushing plant is widely used in road and bridge construction, urban construction, metallurgy, energy, and other departments of crushing, screening. It is especially suitable for surface coal mining areas, which including mobile cone crusher, mobile jaw crusher, mobile impact crusher, tyre mobile crusher and trucked mobile crusher.
Most of the power plant require the final size of the coal which processed by surface coal mining plants to be less than 200mm. But the great majority small and medium sized opencast coal mine does not establish the crushing equipments. At the same time, the particle size of the coal product didn’t reach to the technical requirements, which directly impact on the economic benefits of the mine. To build a fixed crushing station, not only need a one-time investment, but increase cost of the second transport as well. It also affects the economic benefits of coal.Since its inception, crusher portable has been widely recognized and trusted by customers, which creates enormous economic benefit for enterprises. Hongxing Machinery is the manufacturer that always make customers reliable and rest assured. For many years, Hongxing Machinery adheres to the principle of using technological progress to ensure quality enhancement of products, which brings real benefits to customers and realizes win-win situation between customers and company.

As we all know, the ore dressing equipment includes shaking table concentrator, gravity chute separator, magnetic separator machine, flotation concentrator, classifer, mixing barrel and so on. There are a variety of factors influencing iron ore beneficiation, for example its type and parameter.
After a lot of market research, there are usually two ways to investigate the preparation equipment mechanical ability. One way is from the aspect of process capability. We can observe the products" quality to measure if there is something wrong. The other way is to measure directly according to the related standards of mining equipment; for example, we can measure the concentricity of bearing, parallelism of guide rail, vertical degree of axis, gear backlash and hitting power of the machine.
Ore beneficiation equipment mechanical ability is an important standard of measuring equipment processing capacity, also a standard to measure if the mineral processing equipment can meet the quality requirements of the indicators. All manufacturers pay special attention to that how to improve the production of iron ore beneficiation equipment, so the experts of Hongxing Machinery share with you some methods to increase its preparation output.
1. Improve its structure and classifier circulation rate.
2. Change the transmission equipment and improve the transmission capacity.
3. Strengthen the ventilation of ball mill and reduce the over grinding phenomenon of material. We can add a self-made blowing and ventilation device to solve the over grinding phenomenon of material and improve the products quality.
4. Shrink the particle size of materials to be grinded and lower their moisture content. The biggest particle is less than 15mm. the space of article sieve of hammer crusher is 10-12mm, which guarantees the even granularity of materials.
5. Strengthen the management of grinding machine and improve the grinding ability. The grinding body of dry ball mill is commonly divided into two kinds: one is round steel ball type, which is mainly used to crush materials. The other type is steel section, which is used to grind material.Relying on Strong technical precipitation and independent innovation ability, Hongxing Machinery plays an important role in international market, which become one of the most important manufacturing and exporting bases in China. As the typical product of Hongxing machinery, ore separating line has such advantages as reliable operation, easy maintenance, simple structure, low production cost, high productivity, advanced technology and so on.

Cement mill is grinding cement production equipment, along with the people to the mill of the increasingly high demand, high efficiency and energy-saving cement mill is the inevitable development of each manufacturer. The following Henan Hongxing Mining Machinery helps you analyze my factory energy saving cement grinding mill features:
Energy saving ball mill is suitable for grinding various ores and other materials, are widely used in mineral processing, building materials and chemical industry and so on, can be divided into two kinds of dry and wet grinding method. According to the discharging in different ways, can be divided into two kinds of lattice type and the overflow of cement grinding machine. Energy saving cement mill is mainly used for open circuit grinding system. Its characteristic is the system equipment and has the advantages of simple process, less investment, plant covers an area of; in the cement mill adopts the structure of the advanced inner choosing powder special compartment device, a fine grinding barn increased activation device, grinding the end for discharging grate plate, the maximumdecrease grinding barn grinding media size, greatly improving the grinding efficiency, achieve high yield, low energy consumption.
Now use the ordinary cement grinding mill mostly for closed-circuit grinding system, characterized by high efficiency, largegrinding mill output, power consumption province, especially grinding slag cement, performance more prominent. General ball mill output can be increased by about 10% 15-20%, reduce power consumption, in addition, producttemperature can reduce the 20-40 C, the fineness of products are easy to adjust. However, energy-saving cement grinder changed the original mill structure, so that the body, chassis integration, installation can be once and placed on the base plane, spindle double row self-aligning roller bearing can reduce energy consumption by 30%, increase the granularity, processing power increased 15-20%.Relying on Strong technical precipitation and independent innovation ability, Hongxing Machinery plays an important role in international market, which become one of the most important manufacturing and exporting bases in China. As the typical product of Hongxing machinery, hoist bucket has such advantages as reliable operation, easy maintenance, simple structure, low production cost, high productivity, advanced technology and so on.
