Pulverized coal ball press machine ball press machine introduce advanced technology, reliable quality, a machine, strong pressure for large, medium and small enterprises to establish a certain production scale of the production line. For industrial gasification, a variety of boiler type, cold type focus, coal fire, civil coal, civil metallurgy, refractory, medicine and other materials, molding. Strong coal ball press machine after years of industrial use and improvement, compared with other similar products, strong coal ball press machine with the ball high, low power consumption, and compact for easy maintenance and debugging structure distinct advantage. Coal ball press machine principle coal ball press machine hosts powered by the electromagnetic speed motor, the pulley, spur gear reducer, coupling with spread through the rod axis. Driving shaft and the driven shaft through the open gear to ensure synchronous operation. Passive bearing equipped with a hydraulic device behind. Screw feed device by the electromagnetic speed motor drive pulley, worm reducer rotation will be pressure to force the material entered the inlet pressure. Because electromagnetic speed motor constant torque characteristics, when the pressure feeding amount of material equal to the desired host screw feeder, you can maintain a constant feed pressure to pellet quality and stability. Such as excessive feed, feed device of the power transmission overload; feed rate is too small is not a ball. Coal ball press machine structure is composed of 1, feeding parts: the main is to achieve dosing to ensure uniform access to the material between rolls. 2, transmission parts: the main drive system are: motor - triangle strips - reducer - open gear - roll. Host powered by the electromagnetic speed motor, the pulley, spur gear reducer, coupling with spread through the rod axis. Driving shaft and the driven shaft through the open gear to ensure synchronous operation. Passive bearing equipped with a hydraulic device behind. Hydraulic protection means is by the hydraulic pump high-pressure oil into the cylinder, the piston axial displacement. Former head of the piston rod connected to the bearing housing pressure to meet production requirements. 3, forming part: mainly refers to host part of the core part of the roll. When the intake material between the roll into the metal block excessive or hydraulic cylinder piston rod pressure overload, the pump will be shut down, the accumulator pressure change by a dampening effect, the relief valve to open the oil return, the piston rod displacement so increase the gap between the pressure roller so hard object by the pressure roller, the system pressure returned to normal, can protect the pressure roller is not damaged. The machine can adjust the pressure according to pressure the ball density requirements and production flexibility. Coal ball press machine and efficient production of materials of claim 1, the material is absolutely not allowed to have iron or other high hardness block debris to prevent damage to the roll forming machine and the shaft, using department should be installed in addition to iron part in the process of formulating the 2, the material granularity control in less than 1mm particles should be 30-40%; 1-2mm particles should be 30-40%, the largest particles smaller than 3mm of the particles should be at around 10% 3, water control at 8-10% ( How much water into the ball impact on the maximum rate, a little more a little less is not the same, the absolute guarantee uniform moisture, special attention should be) 4, feed must meet, should adopt variable speed screw feeder, observe feed back adjustment 5 supply of new material, a binder and other additives (such as desulphurization agents) users to be on their own according to the coal industry and the environment formulated Zhengzhou City Yonghua specializes in producing briquette equipment, coal ball press machine is the industry leader Location, welcome to visit our company and test machine. http://www.gyyqj.com/
