With the development of mining exploration, the requirement of stone crushing machine is increasing. So there appears kinds of crushers, such as jaw crusher, cone crusher, impact crusher, and so on. The design of mobile crushing plant is the innovation of crushing machine industry, extending the range of coarse and fine crushing and propelling the crusher to the further development.
Mobile crushing plant is the newly designed crushing equipment for crushing stones and construction waste. With the innovation of integration, flexibility, convenience, mobility, it is aiming for dispelling the obstacles in working site, working environment and infrastructure, extending crushing range and improving crushing strength. Therefore, the mobile crushing plant can be driven to any position in the working site and be used for crushing directly without installation, saving the time and transportation cost.
Mobile crushing plant is mainly composed of high efficient crusher, high functional vibrating screen, belt conveyor, electric motor and control cabinet, etc. The whole set is one installation and works coordinately, which fully embodies the convenience and mobility. The mobile crushing plant is mainly used in the fine grinding field, in the application of aggregate handling process, mobile crushing and screening plant instead impact crusher to yield higher hardness and more fine particle size stone product.

Sand Crusher Machine Equipment
Clay Sand Washing is the simplest and lowest cost method of cleaning Clay sand. In some of the very pure deposits that are void of heavy minerals, high amounts of clay and silt, and no surface staining, professional Grinding Mill manufacturers,washing is sufficient to produce acceptable grade product. It may be use ciros sand washing machine. In the process, water is added to the sand and is generally pumped to a cyclone for desliming.
The movement of the slurry passing through the pump and pipeline is sufficient to loosen the small amount of fines or clay that are in the ore body. China Stack Reclaimer Offers,Once the minor amounts of fines or clay have been released from the Clay sand they can be removed via a variety of methods.The entry to the concrete, sandstone aggregate will become the requirements for enterprise value.
And the cement enterprises have formed the complementary advantages with the Concrete Aggregates industry customers, markets, mineral resources, technology and human resources and equipment, which have become one of the major type .And the present mining resources mature crushing and manufacturing technology have the scientific management model ,which just need to bring in the relative crusher ,sand making machine to realize the combination between the sandstone aggregate and cement production .

Caterpillar Machine-Sales Drop Accelerates as Asia Slumps
Global sales fell 4 percent in the three months through January from the year-earlier period, the Peoria, Illinois-based company said today in a filing. That compares with a 1 percent drop reported in the three months through December, which was the first decline in more than 2 1/2 years."There is excess inventory in the supply chain to be liquidated," Ann Duignan, a New York-based analyst for JPMorgan Chase & Co., said in a report today.
The bigger drop in North American machinery sales is "suggesting that production cuts at the company may extend further into 2013 than previously expected," said Duignan, who rates the shares neutral, the equivalent of hold.In the three months through January, Asia-Pacific sales fell 12 percent and North American sales were down 11 percent, Caterpillar said, citing numbers reported by dealers every month. Latin America was up 3 percent, and the region that encompasses Europe, Africa and the Middle East rose 1 percent.
The declining sales come as China, which made up about 3 percent of Caterpillar sales last year, recovers from seven quarters of slower growth and the U.S. economy struggles to grow with recent tax increases and possible government spending cuts to reduce debt. Caterpillar said on Jan. 28 that gains in its sales and profit this year will come in the second half as the world economy improves, forecasting 2013 earnings of $7 to $9 a share on revenue of $60 billion to $68 billion.

Ecological Construction Calling for Environmental Crusher
Concerning on the situation change, it is not difficult to see that the ecological construction will be the topic in industries, including mining machinery, therefore, the reformation of heavy equipment is the key component.It is reported that crushing machine has developed for several centuries in China, and with the breakthrough of technology, crusher technique is also innovating in several aspects, such as breaking process, working mode, production means, and so on.
However, due to the wholesome low level, there is no thorough improvement for crusher and there is still problems like resource and environment pollution. In 2013, the improvement of crushing machine is the crucial factor for mechanical industry. In DSMAC,Vibrating feeders, the new technologies have been applied. Imported the advanced Germany crushing technique, DSMAC made up the cone crusher’s shortcomings of large volume, low capacity and high rice.
Recently, the environment-friendly hydraulic cone crusher is also researched out. The cone crusher can be divided into three categories, GZG Feeder suppliers,including standard cone crusher, medium cone crusher and short-head type cone crusher; crushing cavity chosen is decided by the ore application to meet the needs of medium crushing, fine crushing and super-fine crushing; also the dust removal and noise reductional equipment are used to reach the goal of green production.

Classified Guidance to Apply Impact Crusher
The single rotor Impact Crusher is a kind of crush equipment which to use impact energy to crush material.when it works,the rotor rotate at a high circle speed by the motor'(TM)s force,when the material enter into the hammer'(TM)s working area, the ore crush with the hammer,then the ore will throw to the reflecting part,this is the seconed time crushing,when the ore was reflected from the reflecting board,there is a third crushing on the hammer,again and again.,the ore is getting samller and samller while it go down in the first to seconed and to third reflecting room.
Till the ore was crushed into the proper size,it go out through the exit.to adjust the distance between the single rotor and the reflect board,it can change the shape and the size of the ore.this kind of crusher can control the size of the finished ore,so the big block is not much,the size of the ore is certain in a area.that'(TM)s because the sieve board have the function to control the size of the ore.
The entrance for the ore is on the top of the cursher,there are two sets of the reflecting board in the two side of the crushing room.In addition, in order to meet the nesting size requirements and compensate for wear of the jaw plate, additional nesting population adjustment device, usually put in between the bracket seat and rear rack adjust shim or wedge. However, in order to avoid affecting production, the replacement of broken parts and hydraulics can be used to achieve insurance and adjustments.

Things You Can Use A Rock Crusher For
Each type of rock crusher has a specific purpose in the mining and production process. In addition, there are generally four different criteria that determine what type of rock crushers will used. These include the hardness of the materials that need to be crushed, Portable crushing machine,the moisture content of the raw materials, the abrasion limit of the rock, and the reduction ratio which is what size the crushed product should be compared to the raw material that enters the crusher.
Primary crushers are the largest format of rock crushers. They take the raw ore from the mine and break it down to a smaller size that can be processed further by secondary and tertiary crushers. The types of crushers used for these heavy duty applications are typically Jaw Crushers, Gyratory Crushers, Horizontal Shaft Impactors and Vertical Shaft Impactors. They are extremely large in size and very powerful. They can take rocks that are more than a meter in diameter and make them up to 25 times smaller.
When the rock leaves the primary crusher, it is generally a more manageable size and will be transported on conveyor belts or in trolleys to the secondary and tertiary rock crushers. The Hydraulic Cone Crusher Manufacturers and tertiary crushers are used to further reduce the size of the rock. The purpose of these crushers depends largely on what the end use of the mined rock is. Ore that goes into a smelter will be crushed to a difference size than ore that that will be refined for other purposes. The types of crushers that are used as secondary and tertiary crushers are Jaw Crushers, Hammer Crushers, Cone Crushers and Vertical Shaft Impactors.
