Which kind of mining equipment has core competitiveness?

As the competition between mining equipment is increasingly globalized, market demand is changing continuously. Unique competitiveness of large-scale enterprises will inevitably play an increasingly important role in industrial organization structural system. Continuous improvement of production socialization degree in international scope requires production process to be further collaborative, standardized and professionalized which are precisely the advantages of medium and small enterprises. Hence, at the present stage and in the near future, coexistence of super large enterprises with bipolar characteristics and a large number of medium and small enterprises will become the main form for development of industrial organization. Compared with this situation, unreasonable phenomenon of organization structure of mining machinery equipment in China is still outstanding.

At present, overall efficiency of ore milling equipment industry is relatively low. The main reasons are various. Firstly, technical content of product is low. Secondly, gap between technology-intensive product and users’ requirements is widening. Thirdly, core manufacturing capability of large complete set of equipment with high added value and engineering equipment is insufficient, which virtually bring more pressure to enterprises. So, when continuously deepening reform of large state-owned enterprise, it’s very necessary to stimulate the enthusiasm and passion of independent innovation of enterprise by means of system construction. The experts point out that realizing industrial upgrade is a task which must be finished from the current industrial competition. For enterprises, there are only two ways. The first is to continuously imitate and occupy market share really well. The second is to surpass the copycat and improve core competence and international reputation.

If we observe and assess the international competitive ability of equipment manufacturing industry in China without prejudice, it’s easy to find that the industrial competitiveness must be relatively low when main technical resource especially public technical resource is mostly controlled by state-owned enterprises. In this sense, achievements of mining machinery industry in China are more worth being expected. And only the mining equipment with high technical content and high added value can truly have core competitiveness.Zenith is a professional manufacturer of mining equipment, welcome to visit our company, we never let you down.

The most efficient way of improving grinding efficiency of mill

There are many factors influencing the grinding efficiency of making machine. As for one mill grinder, when processing one mineral, the influencing factors of ultrafine mill efficiency include property of grinding media, matching of grinding media, filling ratio of grinding media, ratio of grinding balls to materials, grinding density and feeding granularity. Among them, the influence of some factors is approximately proportional, some nonlinear, some relevant, and such factors as matching filling ratio of grinding media will change along with the implementation of the grinding process and the loss of grinding media, for this reason, it is very difficult to precisely and scientifically calculate the influence relation of every factor. However, there is one influencing factor which is the most direct, clear and most efficient, feeding granularity.

Working efficiency refers to the working amount finished in unit time. For this reason, grinding efficiency refers to the amount of products meeting the granularity requirement of vertical roller mill in unit time. When the grinding plant, grinding balls and grinding density are the same, the grinding efficiency is mainly related to feeding granularity. Grinding mills are used for processing large materials to products with the required granularity, so that if the granularity of feeding materials is similar to that of required, the working load of grinding mills will be smaller and the working efficiency will be higher.

According to our calculation, when reducing the feeding granularity from 20mm to 5mm, the relative productivity of grinding mills will be improved by about 30%, which means that the ball grinding mill can process 30% more ores in unit time. When such cost as energy consumption and personnel is certain, if 30% more concentrate products can be got in ore beneficiation plant, the increase in economic benefits for the ore beneficiation plant will be huge, for this reason, reducing the feeding granularity is the most efficiency way of improving the grinding efficiency of ball making machine and increasing the benefits of ore processing plant.

Several factors affecting the working efficiency of superfine carbon

The efficiency of silicon carbide ultrafine grinding directly affects the efficiency of the entire production line, after a period of use, we often find that the work efficiency of silicon carbide ultrafine mill as before, in order to restore the ultrafine carbide Work efficiency, and thus improve the efficiency of the entire production line, we have to understand the impact of silicon carbide ultrafine grinding efficiency of the reasons for what.

The third reason is the structural problem of silicon carbide ultrafine grinding, which includes the type of ultrafine grinding of silicon carbide, liner shape, speed, specifications and so on. The different types of silicon carbide superfine grinding media used in the range are also different, the correct use of silicon carbide can be ultra-fine grinding efficiency, otherwise the wrong use will reduce the production efficiency. Under normal circumstances, the spherical medium and long rod-type medium grinding effect is. Ultrafine grinding of silicon carbide grinding grinding efficiency is high, suitable for fine grinding, because the silicon carbide ultrafine mill used in the spherical media in the grinding is the collision point of contact. However, the ultrafine grinding of silicon carbide superfine grinding is thought to be too serious, so the rod carbide superfine grinding is more suitable for mineral grain size below 30 mm and requires the product size of not less than 1 mm ore grinding.

The fourth reason is that the specific operation is used. More parameters of silicon carbide ultrafine grinding is fixed, can not be used in the production of easy to change, and some parameters can be based on the specific use of the situation to make a reasonable adjustment, thereby enhancing production efficiency. So the low efficiency may also be due to the adjustment of some adjustable parameters unreasonable.

Understand the impact of silicon carbide ultrafine grinding work efficiency of several factors, you can adjust the superfine grinding of silicon carbide, and at the same time in the use of more attention, will be able to restore the efficiency of ultra-fine grinding of silicon carbide, and then Improve the efficiency of the entire production line.

The research on new sand making technology and its features

The present sand making technologies mainly include two types: tertiary crushing and rod mill combination sand making technology and vertical shaft impact crusher sand making technology. These two sand making methods have both advantages and disadvantages. Given this, the researchers propose the argument that users only use vertical shaft impact crusher to grind the hard rocks into sand, and through the optimization and adjustment of traditional sand making machine technology reasonable selection of vertical shaft crushing equipment, finally reach the goal of producing qualified sand. This article will give a detailed introduction to the research on the new sand making technology and its features.

As for the artificial sand and stone material production system that is used for processing light and high corrosive parent rocks, the main disadvantages of only using vertical shaft impact crusher to manufacture sand lie in uneven product grading and high fineness modulus of the final sand. If the customers want to properly reduce the fineness modulus of the sand in order to satisfy the project requirement, they only need to properly reduce the average diameter of the sand. According to traditional sand making technology, the new technology makes the following adjustment: the part of coarse sands whose particle granularity ranges from 5mm to 2.5mm are recrushed through the fineness modulus adjusting cabin and the vertical shaft impact crusher rotating with high speed, thus reaching the goal of adjusting the fineness modulus and grading of the final products. As for the selection of crushing equipment, it is for the best to choose the stone impacting stone series vertical shaft impact crusher which adopts the material impacting material crushing principle, thus significantly reducing the abrasion of the equipment caused by the rocks.

(1) This sand making technology is suitable for hard rock with high impacting strength, corrosion and compression strength.

(2) The keys to the new technology are three. Sand making technology: change the rod mill to crushing machine, thus reducing energy consumption and civil engineering; the selection of crushing equipment: mainly choose the stone-impacting-stone vertical shaft impact crusher to reduce the abrasion of the equipment caused by the hard rocks; the fineness modulus adjusting cabin adjusts the fineness modulus of the final sand.

This new sand making technology can not only satisfy the quality requirement of sand, but simplify the sand making process, effectively improve the disadvantages of traditional sand making technology and significantly improve the sand making efficiency, so that it is the development direction of sand making technology in the future.

What affect the grinding granularity of raymond mill?

Raymond mill has been perfect after years of practice and improvement. It is widely used for grinding materials in metallurgy industry, building materials industry, chemical industry, mining industry and other areas. It can meet the requirements of different customers with the interaction of the analyzing machine and fan. Through years of production experience, we have summarized the following factors affect the granularity of Raymond mill:

1. The rotating speed of its main engine.

When the rotating speed of raymond mill is too high or too low, it will make the fine powder enter into the discharging port earlier to affect the fineness of the powder material. The rotating speed of Raymond mill can be adjusted through the adjustment of the engine current.

2. The speed of the blower.

For the materials with light weight, if the blowing speed is too large, the particles which have not reached the requirements will also be blow into the dust collector. On the contrary, for the large particles, if the wind speed is too small, it will affect the discharge of materials, the rotating speed of the blower affects the wind speed, which can be considered as one of the important factors.

3. The wearing degree of grinding roller and grinding ring.

When the Raymond mill is operating, the grinding roller and grinding ring will not contact with each other. With the working of the mill, the wearing degree of the roller and ring will also increase, if the materials cannot be fully ground, the fineness of material will be affected, and the amount of rough particles will also increase.

4. The turbine blade of the analysis machine.

There are large amount of turbine blades equipped inside the analysis machine, which is in sun shape distribution, these leaves will be wore after a period of use, which will directly affect the powder separating efficiency of the analysis machine. The coarse powder enters into the powder collector through the analysis machine, which is an important reason for the too much coarse powder content in the finished product.

Effect of low voltage on ultrafine grinding

Superfine grinding at the time of production, for all aspects of the requirements of the very strict, any one aspect of non-compliance, there may be a decline in production efficiency and the increase in fault, so we must ensure that all aspects of the rationality of the conditions, here is mainly about the voltage is too low, for the impact of the machine. The ultrafine mill in the processing of materials, good performance, not only with the performance of the equipment and quality has a relationship with the external working conditions also have a great relationship, so-called working conditions mainly refers to the operation of various aspects, such as the speed of the feed, and then, for example, the size of the voltage, these aspects are in line with the requirements Equipment to work smoothly, any one condition is not standard, can cause adverse effects in production, here is to introduce the voltage is too low, for the impact of the machine production.

Ultrafine grinding at work, when the voltage provides the machine operation, the required driving force, in general, different types of equipment, the voltage requirements are a rating, if not up to this rating, will appear to start the difficult phenomenon, or even can not start, If the voltage is too low due to voltage instability in production, then will cause the wind pressure to become small, the analysis machine can not work normally, this time, the powder will plug inside the mill, not only affect the output, but also increase the maintenance process, these two aspects for production, are very unfavorable, Therefore, we need to ensure the stability of the voltage in production and meet the requirements of equipment operation.

To ensure the size of the voltage in the production of ultrafine mill, need to install an electric cabinet before installation, and install a stable voltage, this can effectively guarantee the stability of the production voltage, before the power-on, to check the voltage value to ensure that it reaches the rated value, and then open the mainframe, to ensure that all aspects of the conditions meet the production requirements of equipment, In order to ensure the smooth production. In fact, the voltage value will only affect the production of Ultra-fine mill one of the factors, in the actual production, there are many external factors will cause its production of unfavorable factors, so before the start of the inspection and routine maintenance, maintenance work can not be reduced, all aspects of the conditions are standard, to ensure the smooth production.

Cause of severe vibration phenomenon in milling production

Ultrafine grinding in the installation if the plane and horizontal surface is not parallel will occur vibration, but also when the machine installed plane does not correct, will lead to the machine’s main engine and reducer is not two plane, is also the host of the connection wheel and reducer of the connecting wheel of different hearts. This phenomenon can lead to the operation of the device on the mainframe and the operation of the reducer is not synchronized, resulting in vibration. User two can understand, superfine grinding mainframe operation is driven by the reducer, reducer and host parts of the installation plane is not parallel will cause the machine vibration, making reducer and host parts damaged. In view of this phenomenon, the user can adjust the level surface of superfine grinding.

Ultrafine grinding in the ore milling equipment process will occur normal vibration, but because the ultra-fine grinding is fixed on the ground through the anchor bolts, so its vibration amplitude is very small. However, when the local foot bolts are loosened, the vibration amplitude of the superfine grinding becomes larger, which will cause the parts and materials inside the machine to collide, causing the damage of the machine. In view of this phenomenon, the user only needs to fixed the anchor bolt to be good.

The thickness of the material layer in ultrafine mill is also the two factors that vibrate the machine, when the internal material layer of the machine is too thin, the mill roller and the disc between the gap between the small, prone to impact phenomenon, this impact will lead to the vibration of the machine, the user for this phenomenon needs to increase the amount of feed, thereby increasing the thickness of the material layer.

Vibration occurs when the material is too brittle and the size is too large. At this time because the material is too crisp, easy to break, so it will result in a disc on the two parts of the phenomenon, so that the grinding roller and disc impact, vibration, for this phenomenon, the user to control the size of the feed size, larger chunks of material occurrence of this phenomenon is more likely.
