Hammer Crusher: 
 Life is a mosaic hammer forged alloy or high-manganese steel hammer hammer four times, but the price is high manganese steel hammer forging hammer or two times. A medium-sized hammer crusher, hammer uses about 240 kg (n = 24, each about 10 kg), started in 300 days by year, the annual consumption of hammer 72 tons, by 8500 yuan per ton basis, annual consumption of 612,000 yuan, and 2 times a day to replace the hammer, which reduces the production, increased labor intensity, if you use high-mounted alloy hammer, replaced once every 5-7 days, a daily average of only 60 kg, only 18 tons per year, according to 18,000 yuan per ton, the annual cost of 324,000 yuan, compared with each hammer crusher hammer only a year, save 288,000 yuan for the company, if three crusher, a annual savings of 864,000 yuan. 

 Jaw Crusher: 
 A medium-sized jaw crusher teeth if you use high-manganese steel plate, replaced every 15 days, need to be replaced 24 times per year, each of which takes 480 kg to be 11.52 tons per year, per ton of 8,500 yuan, annual cost of 97,920 yuan, if the the use of high chromium complex life is a high-manganese steel tooth plate four times, 50 days to replace one, replace six times a year, was to be 2.88 tons per ton of 1.8 million, was $ 500 million for the company to save more than 47,000 yuan, If the three devices, annual savings of more than 141,000 yuan for the enterprises. 

 Crusher: 
 A crusher if you use high-manganese steel hammer replaced every 10 days, 30 times a year, each of 280 kg per year to be 8.4 tons per ton of 8,500 yuan, the annual consumption of more than 70,000 yuan; the use of high chrome hammer, every year for 5 times, each 1.4 tons per ton of 1.8 million, was $ 250 million annual savings of 46,000 yuan for the enterprises. If the three devices, each year for the company to save $ 130,000. According to expert estimates, the use of high chrome castings, high manganese steel castings than one-third of the cost savings per year. It can be seen, a business decision makers, without any input, just to make a correct choice, you can create huge economic benefits that enterprise.
