前言近年来,为了确保矿物资源的稳定供应,正积极地进行探矿并大规模开发矿山资源。因此所使用的破碎机一般也是大型的,而且要求坚固而易于维护。宇部兴产股份公司在约扎石灰石矿多年开发经验和煤卡的破碎机械制造经验的基础上,根据与美国雷克斯诺德(Rexnord)公司技术协议正在制造以诺德伯格为商标的可靠性高的破碎设备。 Foreword In recent years, in order to ensure a steady supply of mineral resources, exploration is actively carried out and large-scale exploitation of mining resources is under way. Therefore, the crusher used is generally also large, and requires strong and easy to maintain. Ube Industries Co., Ltd., based on its years of experience in the development of the Jotun Limestone Mine and the experience in the manufacture of crusher machinery for coal cards, is building on the basis of Nordkberg's trademark under the technical agreement with Rexnord High crushing equipment.
