A new online tool for the prediction of atmospheric ash during volcanic eruptions has been made publicly available to scientists around the world. Created by researchers at the University of Bristol in the United Kingdom, it will enable forecasts to more accurately predict the spread of volcanic ash clouds, better airspace management, and paves the way for a volcanic crisis. A type of Grinding Machine that grinds a workpiece plane or a profiled surface.The main types are horizontal axis rectangular table, horizontal axis round table, vertical axis rectangular table, vertical axis round table and various special surface grinders.

It has been revealed that in 2010 eruption of the Icelandic Eyjafjallajokull volcano, the ground plane and cancellation of the Easter holiday plan in Europe, may have released more than 10 times the ash than originally thought. "Our research is an important development in our modeling of volcanic pinnates," said Woodhouse, one of the creators of Dr. Mark PlumeRise, the lead author of the original study. "This model can be matched with the state-of-the-art prediction tools used to predict the volcanic ash spread during the volcanic crisis." Prior to this, it was estimated that only the amount of volcanic plume emitted from the volcanic eruptions was measured by the height of the plume. But this method is only reliable in still air. To consider the effects of the wind, mathematicians and Earth scientists at the University of Bristol combine their expertise to create a new mathematical model. The model shows that strong winds are high because they will reach the ash column under calm conditions. This means that estimates can be greatly shed, relying only on feather height to measure actual figures. Now the team has taken their research step and created an online tool that can be used by scientists around the world to predict and monitor how much volcanic ash is released during the eruption process. The information is then fed into a forecast of how the volcanic ash cloud will be transmitted to a more reliable forecast, and how the airspace will need to be managed accordingly. The release of ash during the eruption of the ash, the meteorological simulation of the diffusion of ash clouds into the atmosphere, is an important input," said Dr. Jeremy Phillips, co-founder PlumeRise.
It is used to provide information directly from the volcanic ash advisory center to the aviation industry. We are doing this openly and freely as a web-based tool that anyone wants to use.
Having been tested, PlumeRise has several volcanic ash advisory centers (VAACs) around the world, including the London Meteorological Agency volcanic ash advisory center, covering the United Kingdom, Iceland and the northeastern North Atlantic. It is also used by academic institutions in Japan, Italy, Iceland Meteorological Bureau.
â‘ Horizontal axis table surface grinder
The workpiece is held by a rectangular electromagnetic table or clamped on the table and reciprocated longitudinally.
The wheel frame can be used for lateral intermittent feed movement along the dovetail guide of the slide. The sliding seat can be vertically intermittently fed along the guide rail of the column, and the workpiece is ground by the grinding wheel, and the grinding precision is high.
â‘¡ Vertical shaft round table surface grinder
The vertically mounted grinding wheel spindle grinds the workpiece with the grinding wheel end face, and the grinding wheel frame can perform intermittent vertical feeding movement along the guide rail of the column.
The workpiece is mounted on a rotating circular table for continuous grinding and high production efficiency.
In order to facilitate the loading and unloading of the workpiece, the circular table can also be moved longitudinally along the bed rail.
â‘¢ Horizontal axis round table surface grinder
Suitable for grinding round sheet workpieces, and can be used to tilt and grind round workpieces with different thickness.
â‘£ Vertical axis rectangular table surface grinder
Since the diameter of the grinding wheel is larger than the width of the table, the grinding area is large, which is suitable for efficient grinding.
⑤ Double end grinding machine
The two parallel planes of the workpiece are simultaneously ground by the grinding wheel end faces of the two grinding heads, and there are two types which are the horizontal shaft and the vertical shaft.
The workpiece is guided through the grinding wheel by a linear or rotary feeding device.
This type of grinding machine is highly efficient and is suitable for mass production of parts such as bearing rings and piston rings.
In addition, there are guide grinding machines for grinding the guide surface of machine tools, and special grinding machines for grinding turbine blade profiles.
