Designing green mining machinery is main trend
The domestic demands for energy conservation and environmentally friendly production is increasingly strong; from the development trend Cheap Louis Williams Jersey , producing energy conservation, environmental protection and efficient crusher, sand maker is undoubtedly the dominant direction in the future. Today, crushing equipment production enterprises increasingly focuse on the R & D and produce efficient, energy-saving machinery. Zhengzhou Hongxing Mining Machinery Co., Ltd. crusher and sand making commonly used design principles of long-life, low power consumption and ease of operation, by optimizing the structure of the product and accessories to achieve the most economical form to play crusher efficiency. Zhengzhou Hongxing Mining Machinery Co., Ltd. crushing machinery products are considered the aspects of equipment maintenance treatment, depreciation vulnerability and noise and environmental protection in the initial design phase.
Mining Machinery is a major source of pollution with resources consumption. Faced with increasingly severe resource and environmental constraints, closely around the design and management of 4R's product lifecycle to reduce energy consumption, pollution is an important means to achieve sustainable development strategy. The specific measures: (1) use the design principles of long-life, low energy consumption and reduce the weight. Extend product life and reduce the amount of mechanical production and reduce its scrapped; reduce energy consumption, reduce environmental pollution; lightweight and high efficiency can reduce the consumption of materials and resources. (2) Maximize the use of materials of low environmental load, not use Freon (air conditioning), chlorinated rubber, resin and asbestos and other hazardous materials as much as possible. Make the pollution of waste parts minimization and overall cost optimization; in the initial design phase of mining machinery products, it should be considered of dealing with scrap pieces with simple treatment, low cost and pollution, convenient parts disintegration; (3) use recycled materials and resourcee; (4) reduce the vibration and noise of the machine to reduce the pollution of surrounding environment.
The 21st century, China has become an outstanding mining machinery manufacturing country and get worldwide attention; Through independent innovation and the development of digital, intelligent, ecological, mining machinery will make a greater contribution to China's economic construction and social development.

Modern Paint Ball guns were a natural progression from a 'Ping Pong Gun' that was used by many young 'Warriors' in the 1950's. This 'Toy' would fire Ping Pong balls under air pressure. A hit wasn't as painful as a modern unprotected 'Paintball' hit, because of the deceleration of the very light projectile.
Then the Daisy Manufacturing Company of 'BB Gun' fame came up with the first Paint Ball Gun. The first Paint Ball gun was invented (1970) and patented by a Daisy Employee, James Hale (U.S. patent 3,788, 298 issued on January 29, 1974.) with the original intent of use by the Forest Service and ranchers marking trees for harvest and cattle for selection. The first gun actually designed for playing Paintball was the Splatmaster invented by Robert G Shepherd. This U.S. patent number 4,531,503 was issued to Shepherd on July 30, 1985.
The Forestry version (Nel-spot 007 pistols) was used in a game of 'Capture the Flag' in 1981, boys will be boys. By 1982 some of the entrepreneurial players from that 'Capture the Flag' game, started National Survival Games (NSG) and opening paint ball fields. Charles Gaines, founded NSG. PMI (Pursuit Marketing Inc.) was founded for the distribution and marketing of Paint Ball products and paint ball gear sites. Caleb Strong opened the first outdoor paintball gear site in 1982 in upstate New York. Being in upstate New York, Caleb also opened the first indoor paintball gear site in Buffalo in 1984.
The early marketing of the new sport included articles written by quite a few of those early players and published in Sports Illustrated and other sports genre.
Once established it was only natural to set up a Championship Contest. This was done in 1983 at a paint ball gear site with a purse of $14,000 cash. The sport also went international in 1983 with the opening of an outdoor paintball gear site in Toronto.
More International Venues were added beginning with Australia in 1984, .
