082015041003 Zhengzhou City Hongxin Mines Ltd. to plant Route: Old Town Xingyang Longgang Zone briquette press ball machine roll skin Zhengzhou Economic Development Zone West life, you are welcome to visit! Pressure the ball machine shop display showing a hydraulic protection device is a high-pressure pump oil into the cylinder coal briquetting machine, the piston axial displacement. Former head of the piston rod connected to the bearing housing pressure to meet production requirements. When the intake material between the roll into the metal block excessive or hydraulic cylinder rod pressure overload coal briquetting machine flow chart, the hydraulic pump will be shut down, the accumulator pressure change by a dampening effect, the relief valve turned back to the oil, the piston rod displacement increasing the gap between the pressure roller so hard object by the pressure roller, the system pressure returned to normal coal briquetting machine manufacturers, can protect the pressure roller is not damaged. The machine can adjust the pressure according to pressure the ball density requirements and production flexibility. Zhengzhou Hongxin Mining Equipment Co., Ltd. focuses pressure the ball machine for 30 years, reliable quality and reasonable price, molding equipment is the key equipment in the production of coal, it should be selected based characteristics of raw coal, coal use and pressure forming, etc. Factors basis.
