Sand making machine operation of the general knowledge

2017-11-30

Understand sand making machine, grasp the correct operation of sand making machine, sand making machine (sand making machine) equipment operators required course below we will come to you to explain in detail your sand making machine general operation matters.
How to determine whether the sand machine is functioning properly, there are usually two ways. The first method is to check the material out of the mill, if it meets the requirements, and beating little, it proves that the mill is operating properly, the description is more appropriate, the material size, moisture are good, steel grade is also suitable.
The second approach is to listen to the sound of sand making machine, one steel bar, the sound should be loud, but there is no steel bar lining plate “steel” sound, should be issued normally “rushing” mixed with a slight impact Sound, such as the sound becomes dull, issued a “roaring” sound, the impact of sound can not hear, indicating the warehouse material too much, serious so-called full grinding phenomenon, then immediately stop feeding until the sound to normal When feeding again.
If the sand making machine loud and clear, strong impact of steel bars, indicating less material mill, should increase the feeding. In changing the amount of feeding, should not become too aggressive, should be gradually adjusted.

Analysis of Multipurpose Use of Recycled Aggregate from Construction

2017-11-28

With the booming development of new construction projects such as replacement of old houses and road construction in recent years, the volume of construction waste is rising at an unprecedented rate, which brings considerable pressure on the rapid development of cities. Scientific treatment of construction waste has also become a hot topic of nationals in recent years. In general, the most scientific and practical treatment method is to crush construction waste using crusher equipment and recycle it.
As early as in developed countries, the utilization rate of construction waste has reached more than 98%, but the domestic recycling of construction waste began to emerge in the recent two years. In order to improve the comprehensive utilization rate of construction waste, mining machinery enterprises continue to introduce advanced technologies in the upgrading and research and development of construction waste crusher equipment to keep abreast of developed foreign countries. For example, SBM Mining Equipment Co., Ltd. has been continuously innovating and developing efforts Construction waste crushing equipment, comprehensive utilization up to one hundred percent.
However, because of the difference of granularity of the broken materials, the scope of the recycled aggregate is different. According to the analysis, recycled materials of 0-2.5 mm can be used as the main raw material of plastering mortar or instead of river sand; recycled materials of 0-4.5 mm can be used as main raw materials for bricklaying mortar; and recycled materials of 2.5 / 4.5-10 mm The main raw material for brick making; 10-32 mm recycled material: used as road building material; recycled materials larger than 32 mm can be re-crushed into crushers or used to fill embankments and continue to serve infrastructure and other industries.
SBM has made a significant contribution to the reuse of construction waste recycled aggregates. It not only finds suitable shelter for a large amount of construction waste, but also reduces the construction industry’s exploitation of natural gravel by effective recycling so as to ease the already scarce natural resources The heavy pressure on. After the construction rubbish is processed by the special crusher equipment, its performance is more stable and reliable compared with that of the construction rubbish. It is also safer for the construction of housing roads and makes an important contribution to the environmental protection and the sustainable development of the domestic economy.

Therefore, we need to introduce more effective construction waste crusher, and effective application.
1, towards the development of lightweight and reduction
Current screening machines and crushers all have certain processing capabilities. However, the basic requirements of a mobile crusher are hardly satisfied because of the bulky equipment and the large overall size, which make it difficult to integrate into one platform. Therefore, should be lightweight, small size of the equipment developed to ensure that more convenient and flexible treatment of construction waste.
2, toward the direction of automation
When dealing with construction waste, because of the loud noise and harsh environment, a large amount of powder layer appears in the air and the safety of workers at high speed is threatened by the equipment. When dealing with construction waste, minimizing worker participation and improving the automation of the equipment will become an important equipment for handling construction waste.
3, Towards a diversified mission
In order to be able to better recovery of construction waste, we will be more stringent recovery technology, especially those recycled aggregate materials. Therefore, it is necessary to develop a more suitable construction waste treatment equipment, with the ability to screen and crush construction waste to ensure better treatment of these recycled aggregates, thereby continuously improving the performance of recycled aggregates.

The importance of determining material quality in sand making machine production

2017-11-20

Many machinery and equipment eventually become a non-standard products, in fact, not our processing does not meet the requirements, but our selection of raw materials problems. For example, many sand making machine now is the case, many companies in the purchase of materials due to their own do not pay attention.
Ultimately, the purchase of materials in terms of thickness is not enough, in terms of strength are not enough, eventually resulting in changes in equipment performance and parameters. In fact, in this case, if we can not meet the requirements in terms of structural components, even if we are really very good in terms of power and power, we are all really futile.
In the material we use now, if the designer is required to go through a special accounting, when used are GB materials, our sand material inspection personnel must be strictly in accordance with GB to be tested. To ensure that the material is the national standard materials, in fact, the national standard and non-standard material differences, on the one hand is the appearance of a great difference. For example, the size and thickness of the material, followed by the internal structure in fact, there will be some differences.
After seeing a lot of sand making products nowadays, in fact, many people feel that brand products will be relatively better in terms of performance and profitability. Here, we also suggest that we try our best to choose brand products so that the quality of brand products will bring us better Benefit.
