Case Introduction

In order to meet the demand for limestone materials in the construction of Zhangjiajie-Huaihua High-speed Railway, China Railway 20th Bureau decided to invest in the construction of limestone production line project. This project is a special material yard for Zhangjiajie-Huaihua High-speed Railway of China Railway 20th Bureau, aiming to provide stable and high-quality limestone materials for Zhangjiajie-Huaihua High-speed Railway and ensure the smooth construction of high-speed railway. As an important guarantee for the construction of Zhangjiajie-Huaihua High-speed Railway, we have formulated a detailed production line plan for it based on the terrain advantages of the site and the material needs of high-speed railway. The plan mainly involves the crushing, sand making and screening of limestone materials. The production line consists of Xingaonai Heavy Industry ZG series 1550 vibrating feeder, XGN series 1615 heavy hammer crusher, 1220 light hammer crusher, YKZ series 3070 vibrating screen * 4, PCK series 1520 single rotor sand making machine, and a dust collector device is used. The specific feed particle size is 70-80 cm, and the discharge particle size is four conventional finished materials below 31.5 mm.
