见图1，一种干法回收PCB的整体装置，包括破碎机、磁选机、涡流分选机、静电分离机，所述整体装置由进料装置1与大破碎机2物料入口相连通，大破碎机2物料出口通过第一物料传输装置3与第一磁选机4物料入口相连通，第一磁选机4物料出口通过第二物料传输装置3A与中破碎机5物料入口相连通，中破碎机5出口通过第三物料传输装置3B与第二磁选机4A物料入口相连通，第二磁选机4A物料出口通过第四物料传输装置3C与涡流分选机6物料入口相连通，涡流分选机6物料出口通过第五物料传输装置3D与微粉碎机7物料入口相连通，微粉碎机7物料出口通过第六物料传输装置3E与静电分离机8物料入口相连通。See Fig. 1, a kind of overall device of recovery PCB by dry method, comprises crusher, magnetic separator, eddy current separator, electrostatic separator, described overall device is connected by
大破碎机功率45KW，筛网孔直径25mm；将PCB破碎成25mm左右的小块状。The power of the large crusher is 45KW, and the diameter of the screen hole is 25mm; the PCB is broken into small pieces of about 25mm.
中破碎机功率37KW，筛网空直径10mm；将25mm左右的小块状PCB破碎成10mm左右。The power of the medium crusher is 37KW, and the empty diameter of the screen is 10mm; it can crush small PCBs of about 25mm into about 10mm.
永磁型磁选机能有效选出里面混入的铁块等，避免对后续的设备造成损坏。The permanent magnet magnetic separator can effectively select the iron lumps mixed in it, so as to avoid damage to the subsequent equipment.
涡电流分选机能有效去除其它有色金属。其原理是当导体在交变磁场中产生感应电流，在感应电流所产生的磁场与外加磁场相互作用下，导体受到涡电流的作用，使物料运动产生偏向，从而使导体与非导体产生分离。分离系数与物质的导电率和密度有关，如铝、铜、镁等金属的分离系数大，而锌、铅等分离系数小，从而能够将废料中的不同金属分选出来。Eddy current separator can effectively remove other non-ferrous metals. The principle is that when a conductor generates an induced current in an alternating magnetic field, under the interaction between the magnetic field generated by the induced current and the applied magnetic field, the conductor is subjected to the action of eddy current, which makes the movement of the material deflected, thereby separating the conductor from the non-conductor. The separation coefficient is related to the conductivity and density of the substance. For example, metals such as aluminum, copper, and magnesium have large separation coefficients, while zinc, lead, etc. have small separation coefficients, so that different metals in waste can be sorted out.
微粉碎机功率75KW，筛网空直径2mm，将10mm左右的小块状PCB破碎成2mm左右。The power of the micro pulverizer is 75KW, and the diameter of the screen mesh is 2mm, which can crush small PCBs of about 10mm into about 2mm.
静电分离设备利用静电原理将金属和塑料类分离。Electrostatic separation equipment uses the principle of static electricity to separate metals and plastics.
