Recently, the client from Russia ordered a set of DPC2018 hammer rock crushers , whose capacity is 400t/h, crusher hammers are 40, and output size is 25mm. And this equipment is used for crushing limestone in limestone sand making production line. Founded in 1997, DSMAC began to specialize in researching and producing cement crushing equipment, especially independently developing the patent product single-stage hammer crusher. The single-stage hammer crusher can crush the large ores into required size in one stage, which replaces the traditional two-stage crushing, simplifies the technical process and reduces the cost. Mr. Fan, the chief manager from production site, said, “Many clients don’t have a good knowledge of DSMAC, so they called DSMAC to consult their required products, but they still don’t trust the quality of these products. But after they visit the production site, they are greatly moved by the production site, and they demand to sign the agreement at once.” Especially, in 2008 DSMAC successfully developed and produced the largest double-rotor single-stage hammer stone crusher 2DPC2325 in China, whose capacity, rotor specification and crusher hammer amount all break the records in the world. In addition, DSMAC also independently developed and produced its mating crusher hammers, which are applied the internationally advanced AMC composition material, are named “big gold tooth” super crusher hammers, and can last 50%-100% longer service life than the high quality Mn18Cr2MoNbRe. “We usually order the crusher hammers from crusher manufacturers, but they are easily worn out, and we could not find good processing factories, so when we visit the crusher manufacturers, and we finally find that they don’t independently produce the crusher hammers while purchase them from other factories to achieve the price difference from us. Now, we visit your crusher hammers producing site, so we totally trust you.” The client from Russia said. What gives us even greater strength is our R&D capabilities. We have 55 dedicated R&D engineers, who have already created products with 28 patents, including a Limestone Ore Crusher with one of the largest outputs available and a crusher rotor and hammer head with up to four times the life span of those of our competitors, a machine now popular in more than 20 countries. Our crushers are so strong that they can be used for up to 20 years.
