为适应喷锚支护新工艺的发展,由长沙矿山研究院、江苏省海门电机厂、第十五冶金建设公司和江苏省冶山铁矿等单位研制成SP—2型转盘式混凝土喷射机,在冶山铁矿进行了一年多的工业试验,共喷射混凝土732.2立方米,证明该设备是国内现有混凝土喷射机中综合性能较好的一种,深受操作工人的欢迎。这台喷射机结构简单、容易加工、易损件少、拆装和维修方便;设备体积小、重量
In order to adapt to the development of the new process of spray-anchor support, the SP-2 type rotary concrete sprayer was developed by Changsha Mining Research Institute, Haimen Electric Motor Factory of Jiangsu Province, 15th Metallurgical Construction Company and Yeshan Iron Mine of Jiangsu Province. More than one year of industrial trials were conducted at Yeshan Iron Mine and a total of 732.2 cubic meters of concrete was sprayed. This proves that the equipment is a better one in the existing domestic concrete jets and is welcomed by operators. This jet machine has a simple structure, easy processing, less wearing parts, easy disassembly and maintenance, and small size and weight.
