Sand Introduction: With the continuous development of national infrastructure construction, the depletion of old-fashioned mechanical Sand natural sand resources have been behind the production of the required accessories Sand, Sand need for a new and efficient to the market meet increasingly tight supply of sand and gravel. In this background our research staff after years of research, reference works abroad crushing machine and usage based on user feedback, combined with its advantages, with the joint efforts of the National Institute of Machinery and expert design and development of a new type of first three generations of dual-purpose machine gravel (sand machine). Its overall performance is superior to the crusher, rod mill Sand, through Impact Sand Sand manufacturers, as well as soft cone crusher and hammer crusher. The device is suitable mechanism of artificial sand, Sunaba, highway, rail, water, construction, cement, refractories, metallurgy, glass, sand and other industries, is the production of high-quality sand device of choice. Single Roll Crusher Sand with small 16O0mmx27O0mm single roll crusher, this transformation of single roll crusher specifications remain unchanged for gear, the tooth structure and configuration to improve and perfect: a spiral arrangement of teeth, overcome sintering machine impact caused by intermittent discharge load vsi sand making machine, so the workload evenly, small motors shock, smooth start, low energy consumption. 2 Improved form hammerhead structure, enhanced hammer breaking capability, ease of welding surface wear-resistant materials, improve the wear resistance, thereby increasing the life of the hammer. 3 shaft and bearing are water-cooled, reducing its thermal deformation. 4 multi-level signal control Sand, in order to grasp the emergency stop time, to facilitate timely maintenance. 5 optimization process configuration, rational arrangement of space under the material to ensure a smooth discharge. Sand manufacturers, Yuxin Senda (certified), Emeishan Sand Co. provided by Henan new Senda Heavy machine. Henan new Senda Heavy Machinery Co., Ltd.
