According to a recent study, the number of hot weather increases year by year due to climate change and brings about the potential to reduce the productivity of workers. The soaring energy costs, major changes in agricultural production, high crime rates, and severe damage to the coastal areas have all brought economic problems that come from the tropics.
For outdoor work, negative productivity seems to start at about 79 degrees Fahrenheit (26.1 degrees Celsius), and efficiency drops sharply when it reaches 90 degrees Fahrenheit (32.2 degrees Celsius). From the current forecast of greenhouse gas emissions, by the end of this century, most of the southern part of the United States will experience more than 90 degrees Fahrenheit over five months in one year. At this rate, the productivity of American workers will fall by 2% by 2100. This compares to the 2008 recession of the Greek economy with less than 1% of productivity decline. Personally, it provides a $504 surcharge for each man, woman and child. In addition, in the areas of poverty and agriculture, costs will increase substantially.
The decline in productivity is the biggest blow to the economy. Higher temperatures mean more demand for electricity, which means higher energy costs unless the country makes concerted efforts or breaks through fossil and fissile power generation. At the end of the century, the average annual increase in costs in very poor areas was 287 US dollars, which may have more than doubled. Violent crimes may also rise. Of course, the destruction of the warm coastal areas caused by sea level rise will cost the population hundreds to thousands of dollars each year, but if you want to save the money, then due to heat and humidity-related mortality Will rise. "After 100 years, because of excess calories and humidity, there will be a 10-20 times increase in related mortality," said Dr. Alfred Sommer of Johns Hopkins University.
Universal crusher is suitable for pharmaceutical, chemical, metallurgy, food, construction and other industries. It can process hard and hard materials, including plastic, copper wire, Chinese herbal medicine, rubber, etc. It can also be used as the supporting equipment before the processing of micro crusher and ultra-micro crusher. Its powder collecting chamber adopts fully enclosed noise reduction structure, which can effectively reduce the working noise. The machine is equipped with a cooling device to reduce the temperature and work more smoothly. The motor speed of the machine is 5000 RPM. The machine is made of lcr18Ni9Ti stainless steel material, with strong wear and corrosion resistance characteristics, suitable for processing advanced and corrosive materials. The machine adopts the impact crushing method, so that the material into the crushing chamber, by the high-speed rotary six movable hammer impact, through the gear ring and the material collision with each other and crushed, crushed material with the help of air flow, through the sieve into the powder bag, leaving no residue. It has the advantages of high efficiency, low noise, reliable work performance and product quality, safe operation, drug hygiene and low loss.
1. Before using the universal jet mill, check whether all fasteners of the machine are tightened and whether the belt is tightened.
2. The running direction of the spindle must conform to the direction of the arrow shown on the protective cover, otherwise the machine will be damaged and personal injury may be caused.
3. Check whether the electric appliance of the mill is complete.
4. Check whether there are metal and other hard sundry objects in the crushing room of the mill, otherwise it will break the knife tool and affect the operation of the machine.
5. The purity of the material must be checked before crushing, and no hard metal sundry is allowed to mix in, so as not to damage the dao tool or cause combustion and other accidents.
The oil cup of the crusher should be frequently injected with lubricating oil to ensure the normal operation of the machine.
7. Stop feeding before shutdown, if not continue to use, to remove the machine left behind.
8. Regularly check whether the screen is damaged. If there is damage, it should be replaced immediately.
9. When using, if the crusher will have small vibration, be sure to tighten the handle connecting the cover to avoid accidents.
