Method and installation for screening and drying strand material upstream of a distribution machine in the course of manufacturing wood material boards

Abstract

The present invention relates to a method and an installation for screening and drying strand material (1) of a distribution machine in the course of manufacturing wood material boards, wherein the strand material (1) still in the moist state is screened with a screening device into at least two different fractions of strand material. At least one of the screened fractions is fed to at least one dryer, and the feeding of the strand material to the dryer is carried out by means of a conveying device, which is controlled by a control unit. The control unit assures a uniform, predetermined weightand/or volume input into the dryer(s) by measuring the mass and/or the weight per unit area of the strand material by means of a measuring device.
本发明涉及在材料板的制造过程中用于在铺装机之前对散料(1)进行筛分和干燥的方法和设备,其中,散料(1)在提供或者制造之后经受干燥和可选的涂胶,最后在铺装站中在成形带上被铺装成板坯并且在接下去的过程中借助压力和热量被压制成材料板。本发明的方法在于,用筛分装置(2)将尚处于潮湿状态的散料(1)筛分成至少两个不同部分的散料(13、14),至少一个筛分后的部分被送入至少一个干燥器(5、8),借助由调节装置(10)控制的输送装置(4、7)执行散料(13、14)到干燥器(5、8)的输送,以及调节装置(10)借助测量装置(11)对散料(13、14)的质量和/或单位面积重量的测量来确保均匀的和预定的重量和/或体积加料到干燥器(5、8)中。
