The working efficiency of a crushing machine is determined by its working principle Cheap Daniel Sturridge Jersey , which is closely linked to the mechanism of material crushing. For this reason, it is necessary to systematically research the crushing mechanism of the materials and comprehensively describe the working condition of the crushing equipment so that the purpose of high efficiency and energy conservation can be achieved. Some scholars in foreign countries think that the following research work should be done in order to realize the goal:

1. The physical action of the crushing process;

2. Research on the crushing process of the single particles;

3. Research on lamination crushing;

4. Mathematical simulation of the crushing process;

5. The working condition and optimum control of the crushing equipment.

No matter what kind of cement is ground, the final grinding system of the cement mill is that most economical and its electricity effect is the most significant. When used in different powder grinding systems, the cement mill has different production increase and energy consumption effects.

1. Pre-grinding system.

Generally speaking, the pre-grinding system can increase the production by 20-50% Cheap Connor Randall Jersey , and save 9-10kwht of electricity, equals 15-20%. When the ratio between the throughput of the materials and the ability of the mill system increases, the cycle load of the roller crusher can be increased in order to improve the production capacity of the powder grinding system and reduce the unit electricity consumption of the system.stone crusher:http:www.hx-crusherstone_crusher

2. Mixed grinding system.

The mixed grinding system is able to increase the production by 80-100% and save electricity by 30-50%. The feature of this system is that it returns part of the coarse powders inside the powder selection machine to the roller crusher to be crushed again together with the new materials and return the other part directly to the powder grinding machine for grinding. It can also return the boundary materials to the roller crusher for crushing again. The advantages of boundary materials cycle are: firstly, evenly mix the materials inside the materials stock bin so that the roller crusher can run stably and the electric current has small fluctuation; secondly, after cycle crushing Cheap Cameron Brannagan Jersey , the granularity of the materials that go into the grinder can be reduces and the production capacity can be further improved; thirdly, increase the amount of the coarse powders inside the powder selection machine that is returned to the roller crusher and let the roller crusher fully play its role of saving energy.

3. Semi-final grinding system.

The ability of the semi-final grinding system to increase production and save energy is determined by the crushing ability of the roller crusher.

4. Final grinding system.

The final grinding system is able to save electricity by 50-68%.

" Surprise decision awards ‘greatest living poet’

Bob Dylan, regarded as the voice of a generation for his influential songs from the 1960s onward Cheap Ben Woodburn Jersey , has won the Nobel Prize for Literature in a surprise decision that makes him the only singer-songwriter to win the award.

 

The 75-year-old Dylan - who won the prize for ""having created new poetic expressions within the great American song tradition"" - now finds himself in the company of Winston Churchill, Thomas Mann and Rudyard Kipling as Nobel laureates.

 

The announcement was met with gasps in Stockholm's stately Royal Academy hall, followed - unusually - by some laughter.

 

Dylan's songs, such as ""Blowin' in the Wind,"" ""The Times They Are a-Changin Cheap Andrew Robertson Jersey ,'"" ""Subterranean Homesick Blues"" and ""Like a Rolling Stone"" captured a spirit of rebellion, dissent and independence.

 

More than 50 years on, Dylan is still writing songs and is often on tour, performing his dense poetic lyrics, sung in a sometimes rasping voice that has been ridiculed by detractors. Some lyrics have resonated for decades.

 

""Blowin' in the Wind Cheap Alex Oxlade-Chamberlain Jersey ,"" written in 1962, was considered one of the most eloquent folk songs of all time. ""The Times They Are A-Changin,'"" in which Dylan told Americans ""your sons and your daughters are beyond your command,"" was an anthem of the civil rights movement and Vietnam War protests.

 

Awarding the 8 million Swedish crown ($930,000) prize Cheap Alex Manninger Jersey , the Swedish Academy said: ""Dylan has the status of an icon. His influence on contemporary music is profound.""

 

Swedish Academy member Per Wastberg said that ""He is probably the greatest living poet."" Asked if he thought Dylan's Nobel lecture - traditionally given by the laureate in Stockholm later in the year - would be a concert, Wastberg replied ""Let's hope so.""

 

Over the years, not everyone has agreed that Dylan was a poet of the first order. Novelist Norman Mailer countered: ""If Dylan's a poet, I'm a basketball player.""

 

Sara Danius, Permanent Secretary of the Nobel Academy Cheap Alberto Moreno Jersey , told a news conference there was ""great unity"" in the decision to give Dylan the prize.

 

Dylan has always been an enigmatic figure. He went into seclusion for months after a motorcycle crash in 1966, leading to stories that he had cracked under the pressure of his new celebrity.

 

He was born into a Jewish family but in the late 1970s converted to born-again Christianity and later said he followed no organized religion. At another point in his life, Dylan took up boxing.

 

Dylan's spokesman, Elliott Mintz, declined. Wholesale Jerseys China Free Shipping   Wholesale NBA Jerseys   Wholesale Jerseys   Wholesale Cheap Jerseys   Cheap NCAA Jerseys Free Shipping   Cheap NBA Jerseys From China   Wholesale Soccer Jerseys Online   Wholesale Cheap Hockey Jerseys China   Wholesale Authentic Football Jerseys   Wholesale College Jerseys China
