Japan introduced pneumatic pipeline system container

o the main blower manufactured by the gas flow is 470Nm/min and 550Nm/rain, the maximum air pressure is 2800kg / 'm: and 4300kg / m,. Pipe at both ends of the rotary launcher in the direction of convertible container group. Mobile shunting in need of repair system for the introduction of container transportation system or group of container fixed set of push delivery systems. Located in the loading station by the total control of a personnel management system to monitor the functioning of the pipeline, in addition to the container group needed maintenance and repair personnel, the unloading stations generally do not need staff. Container group control device to adjust the speed and control of braking zone group of each container of automatic operation, loading station, unloading station, pipeline across the shunting device and the launch of the container group. . 8 -} | l for all aspects of operation must be strictly synchronized in order to ensure that the entire transportation system in the container group 23 to maintain at all times equal to the distance a group of some of the container to leave the mine in the pipeline, some of the container group to return mine in the pipeline, Some of the container group in the loading, unloading some of the container group. The location of the container group by the magnetic sensor on the container wall can be monitored in the control room. Open with the top of the container, in the period through the pipeline operation, a small amount of dust will be taken away by air from the limestone surface, but it does not matter, given the flow speed slightly faster than the speed of the container group, put the dust into the air in the end of the dust collector in the pipeline. Trouble-free operation of vessels for pipeline transportation systems in the Karasawa limestone mine has been open for 9 years running, without any serious problems. Electricity demand is about 2.5kwh, operating time is the effective time of the initial 94% and 98%, l6-hour work shift system is 8 hours a day. Staffing as follows: class 2 operator, a total of four two classes; inspectors class 1, two classes a total of 2; maintenance staff two (animal husbandry, working during the day), a total of eight. From November 1991 since the implementation of pneumatic containers pipeline system 24 hours a day 8-hour shift, the current operating time for its effective time 9D ~ 94%. The transportation system is safer than the belt conveyor belt conveyor line maintenance and replacement needs roller. Container pipeline system power consumption is estimated to 0.7kwh / t ・ km. It seems higher than other types of delivery systems, but general, and in the absence of a large number, the downhill case pneumatic pipeline system power consumption is about 0.2kwh / t ・ km. Pneumatic pipeline system to other container uses Akima railway tunnel in Japan, mining, container pneumatic pipeline system used to exclude waste rock, the project has been started for some time; be completed in two years. Container for the Akima tunnel pipeline system in many important respects from open pit operation in karasawa container pipeline system. For example, it is only a transfer from the time dependent g. Man of the temporary transportation equipment, Nkarasawa pipeline system open pit mine to be fixed long-term transportation equipment but their basic principle is the same. Pneumatic solid container pipeline system on the environmental pollution and its unique advantages to in the excavation tunnel in the transport of waste rock has great potential. Pneumatic pipeline system since the container has the following characteristics is bound to expand its influence, that is clean, safe, do not pollute the environment, suitable for conveying bulk materials continuously, to adapt to a variety of load types and working environment, protected from the weather, cost do most of the investment pipeline maintenance and production efficiency. In addition to other transport can transport ore limestone, sand, gravel, coal, cement, and mine tailings and other waste materials. It will no doubt be widely used in mining. Pan Lili Excerpt official British Mining Journal December 1993 hearing, 204 ~ 29g pages Wang Niansheng world since high school f0/70 grade, high-quality phosphate rock reserves are dwindling and low-grade, not to people familiar with the amount of phosphate rock mining increasing. To ensure successful and economical phosphate production, to be through laboratory and pilot plant test on the phosphate rock in a variety of processes to study carefully the behavior. Testing of ore samples must be representative of anxiety, test conditions, to fully simulate the conditions of industrial production is very important to these two points. When the inspection system of fertilizer from mining to the joint venture must study the whole project from scratch, in addition to factories and mines where conditions, process selection and plant design should be taken into account. Although the majority of available phosphoric acid production process is competitive, but never any one process can be dominant under all production conditions. Any process of evaluation are required. ffI. ● l {● shovel set left D. , Enough scattered abnormal test test maroon stone statue brand-pen
