How to improve the economic benefits of vertical grinding of ore materials?

There are many ore materials processed by Vertical Roller Mill. In order to respond to the national energy conservation and emission reduction call, many industries currently use vertical mills for processing, thus achieving the effect of energy saving and emission reduction. There are many types of micro-grinding materials. The powder sorting machine, the grinding roller device, the grinding disc device, the pressing device, the reducer, the motor, the casing and the like are composed. The rotary part of the ultra-fine classifier is the core component of the classifier. The dynamic balance will directly affect the performance, output and service life of the classifier.
When the vertical mill is used to process limestone materials, the centrifugal type separator is used in combination with the sand making line. The traditional sand washing machine wastes natural resources, although the economic benefits can be guaranteed, but the environmental benefits are poor. However, the use of a screening machine has a complicated structure and requires frequent replacement of the screen, which is complicated in steps and labor-intensive. The influence of the ultra-fine classifier on the working condition of the mill is mainly reflected by the power class of the powder, the cycle load rate and the grinding power of the mill. The influence of excessive stone powder content on cement and asphalt concrete volume parameters have important significance for the performance of asphalt mixture.
During the working process of the Vertical Roller Mill separator, the material enters the classifier from the feed port, passes through the inner cavity into the throwing disc, and then passes through the centrifugal action to the inner chamber of the classifier. The large blade provides updraft, coarse The material is blocked by the auxiliary blades and discharged from the coarse feed port. The fine material is taken up by the ascending airflow to the outer bin. When it reaches the return air blade, it enters the inner bin along the gap of the return air blade to form a circulating airflow and can be sorted three times, and a small part of the fine powder is discharged from the fine powder port. The complete set of equipment can not only increase production, but also improve the quality of pulverized coal and stabilize the thermal system.

Where to check before using the mobile crusher

To monitor the fault without stopping the machine, the first step is to understand the various operating parameters of the machine during normal operation of the crusher. It includes the production capacity of the mobile crusher during operation, the machine sound during operation, and the active state during operation. Only after understanding these basic states can the machine’s anomalies be noticed in time. With the machine running normal state data as the basis, we must also understand the characteristics of some machines when they are abnormal. For example, sometimes the machine will have a large shaking sound due to the looseness of the screw. For example, sometimes the damage of the internal parts of the machine will result in a decrease in the production of the machine, and sometimes the damage of the machine will result in a decrease in the yield of the produced product. phenomenon. These state features require continuous accumulation of experience in the usual production process, and always pay attention to these abnormal characteristics when using the crusher, so that machine failures can be discovered and maintained in time. Of course, in addition to these measures, these professional monitoring instruments can also be used to monitor the operating parameters of the crusher. For example, fault monitoring can be performed by monitoring changes in the chemical composition of the crusher oil. When these measures are combined, the normal left turn of the machine can be ensured. The current society is developing very fast, and we need to have a better grasp of the knowledge of crushers. The mobile crusher early inspection in normal operation has long known that this preventive work can greatly reduce the downtime in production, thereby greatly improving production efficiency.

Mobile crusher uses and advantages

First, the integrated whole unit The unit installation form of the integrated unit eliminates the complicated installation of the infrastructure of the separate components and reduces the material and working hours. The reasonable and compact space layout of the unit improves the flexibility of the station.
Second, the Mobile Crusher is flexible The mobile crushing station has a high vehicle ground, the vehicle body width is smaller than the operating semi-trailer, and the turning radius is small, which is convenient for ordinary road driving, and is more convenient for driving in the rugged road environment of the crushing field. It saves time for quick entry to the construction site, and is more conducive to stationing in a reasonable construction area, providing more flexible space and reasonable layout configuration for the overall crushing process.
Third, reduce the material transportation costs and break the mobile crushing station, which can crush the material on the first line, eliminating the intermediate link of material transportation and re-breaking, which greatly reduces the transportation cost of materials. In addition, the extended unit can directly send the broken materials into the transfer car bin and turn off the site.
Fourth, the series of Mobile Crusher directly and effectively integrated with the operation can be used independently, or can provide more flexible process configuration for the material type and product requirements of the customer, and meet various requirements such as mobile crushing and moving screening. The requirements are to make the organization and logistics transfer more direct and effective, and to minimize the cost.
V. Adaptable and flexible configuration The mobile crusher is suitable for the coarse crushing and fine crushing screening system. It can be operated independently by a single unit, or it can be flexibly composed of the system configuration unit. The discharge hopper side outlet provides a variety of configuration flexibility for the screening material conveying mode. In addition to supplying power to the unit, the diesel generator in the integrated unit configuration can also be configured to provide unit power supply to the process system.

What are the effective measures to reduce the accident of the crusher?

1. Do a good job of temperature control management. The cone is broken in normal work, and each component has a normal operating temperature range. If the temperature of a component is abnormal, it is likely to cause damage to the relevant component. Especially for bearing parts, etc., if the temperature is too high, it must be carefully checked. Usually, the lubrication is not enough to cause the bearing to burn out.
2, do a good job of dust and dust removal. Due to the special nature of the Crusher Equipment production environment, a large amount of dust and fine particles will inevitably be generated during the working process. If the dust and dust removal faults are not done, the impact on the equipment will be very large. Especially when these dust particles enter the lubrication system, the wear of the equipment itself will be greatly accelerated, and the service life of the crusher equipment will be affected, which will easily cause the failure of the crusher equipment. In response to such problems, we must not only do the dustproof work of mechanical equipment in the daily production work, but also pay attention to the quality when selecting the accessories with higher requirements. , varieties with less impurities.
3. Corrosion of corrosive materials should be protected. In the use of the Quarry crusher, due to its wide range of use, it is easy to damage the broken parts of the crusher when crushing corrosive materials such as acid and alkali. Usually such materials need to be subjected to relevant acid reduction, alkali reduction treatment or special crusher related components before being crushed. The specific situation needs to be considered and selected according to the corresponding production environment and requirements, as well as the cost of demand input.

We must learn and carefully maintain him, proper maintenance. The performance of the machine is improved and the life is continued.

Main structure of composite hammerhead crusher

The composite Stone Crusher divides the hammer head into two parts, the hammer handle and the hammer end. The hammer handle and the hammer end are made of different materials. First, the hammer handle or the hammer end is prefabricated with a material, and then the pre-manufactured hammer shank or hammer end is placed in the mold to cast another liquid metal for casting. A portion of the hammer is prefabricated and then cast to form another portion of the hammer. The prefabricated hammer handle is generally made of carbon steel. The commonly used carbon steel is ZG35 and ZG45. It can also be directly bent into a hammer handle by using the steel profile, and then the hammer end is cast. The hammer end material is generally made of high chromium cast iron. Another method is to pre-manufacture the hammer end and post-cast the hammer handle.
The material selection of the hammer handle and the Crusher Machine, one combination is the material selection of the hammer handle, ordinary carbon steel such as ZG25, ZG45, the hammer end is made of high chromium cast iron; the other combination is the hammer handle is high manganese steel, the hammer end is high manganese steel. The mother is inlaid with a hard alloy block. 2, two-liquid bimetal composite casting hammer two-liquid bimetal composite casting method is to first cast a certain thickness of the first metal liquid into the mold, while pouring molten high-temperature protective agent to prevent the height of the joint is certain The second molten metal is poured after the time interval. High chromium cast iron + high manganese steel adopts the whole lost foam vacuum suction casting process. The steel structure which is cleaned and dried by dilute hydrochloric acid is placed in the prepared EPS pattern. The material is Q235A, the shape is box-shaped structure, one end is open, and the casting is required to be high. When chrome cast iron is not melted through, first cast high chromium cast iron and then cast high manganese steel.

An irreplaceable sand making machine in the mind of the user: a new sand making machine

In the mining industry, many users choose to use a new sand making machine to process sand and gravel materials. It has the characteristics of large output, high cost performance, and simple equipment maintenance. In daily operation, there are three sand making machine methods, and Xiaobian carefully introduces them.
1. Impact sand making. Instant impact sand making is the material that is subjected to instantaneous impact force to make sand. This type of sand making equipment is mainly a impact crusher or an impact sand making machine. Its main features are high sand making efficiency, large sand making ratio and low energy consumption.
2, 劈 type sand. The shovel sanding method is to place the material between a flat surface of the sand making equipment and a working plane with sharp edges. When the working plane with sharp edges is pressed against the material, the material will be along the direction of the pressure line of action due to the splitting plane. The tensile stress reaches or exceeds the tensile strength of the material and is cleaved. This type of sand making equipment is mainly a cone sand making machine or a hammer type sand making machine.
3. Press-type sand making. The material is placed between the two working faces of the sand making machine. After the pressure is applied, the material is sanded due to the compressive stress reaching the compressive strength. This method is generally suitable for the sand making bulk material. This type of sand making equipment is mainly a roller type sand making machine.
The above three methods of sand making are used in the mining industry, but which one to use depends on the equipment. Xinlian specializes in the production of sand making equipment. No matter what materials and production, we have equipment models to meet. If you need it, you can come to our factory for consultation and purchase. We will give you a satisfactory answer!
