And zhoufengwu hold the same view of citic securities machinery industry veteran analyst guoyaling also said, the u.S.Subprime mortgage crisis in the influence of our country industry is primarily through demand of the formation of the indirect.At present,raw material mill our country's exports to the united states mechanical product advantage have focused on the price, so even if the economic downturn, to the low end of the economy and the possibility of product demand weakened is small.For the growing risk the appreciation of the renminbi, guoyaling suggest enterprise shall prepare more hands,jaw crusher in addition to taking hedging means besides, still should lock customers high quality, sign the rmb long-term agreement.At the same time, the enterprise can also use the foreign key parts purchasing.At present, china's exports of mechanical products with parts and the low end products are in the majority,china vibrating feeder the assembly for the high-end parts of still rely on imports, such as using foreign exchange purchase high-end parts can effectively reduce the cost.In addition, the enterprise can be reduced rmb loan scale, increasing foreign currency loan.
Impact crusher is one of the most important crushing equipment which is widely used in mining, chemical, metallurgy,cement rotary kiln building materials, electricity and other industries.The hammer is the main wear parts, its quality direct impact the crushing efficiency of impact crusher.In addition to being hit, the hammer is also impacted by the material during crushing stones.So after long-term repeated use,vibrating screen the hammer's surface will change.Currently the majority of hammer is made of high-manganese steel.
How to use cone limestone crusher machine1.When cone crusher is operating, even feeding should be delivered.If the feeding is uneven, production capacity will be reduced, product granularity is too big, spring action is frequent, pressure of bowl-shaped bearing is high, energy consumption is increasing.
From the various sub-sectors of the jaw crusher, engineering jaw crusher operating income and net profit growth than any other sub-sectors of industry growth leader."12th five-year" period, the compound growth rate can reach about 20%.As the "12th five-year" seven strategic emerging industries, high-end equipment manufacturing industry will be the major support of the policy.Overall, the profitability of the jaw crusher industry has been significantly improved, which is reflected in two aspects: first, the return on net assets rose to 15.53 percent from 14.05 percent in 2009.Return on total assets rose to 6.49 percent from 5.23 percent in 2009; the industry's net profits grew faster than operating income growth.Mainly because the steel and other raw material prices have remained stable while the price has increased, making the annual increase in gross profit margin.Rose from 19.21% to 20.56%, 1.35 percentage points, three costs during the management expense ratio decreased significantly.In 2010 than in 2009, down 0.52 percentage points, management efficiency is also enhanced profitability of the industry.
The jaw crusher,impact crusher,cone crusher and pulverizer machine are the popular crushers with stones in mining industry.Blog; trituradora; trituradora blog;.
Rock is fed into a large opening at the top of the cone crusher where it is squeezed between the mantle and the cone.As the size of the rock decreases, pieces fall into lower levels of the crusher where they continue to be worn and broken down further.Once small enough, the fragments of rock exit through a narrow opening at the base of the machine.Cone crushers manipulate rock between a fixed cone and the movable cone (the central shaft).The width of the exit opening is adjustable through ascending and descending the fixed cone which allows the rock to be crushed to a variety of sizes.This method is more advanced than the one used in jaw crushers.You can see how jaw crushers work by clicking here.
