从运输机上方来固定皮带,矿物在运输过程中不致泄漏。此法看起来似乎简单,然而,直到现在才由利登—阿利马克(Linden—Ali-mak)研制出来。这种运输机现正在试验,再过一年左右,它将可供国际采矿工业应用。这种运输机有许多优点,它可以在高达45%的坡度上输送矿物(因为矿物是被约束在皮带的内侧),而普通运输机只允许17%～18%的运输坡度;它能在0.5米的曲率半径上运行,皮带可以比一般的皮带运输机绷得更紧,因为一般皮带运输机,只有靠皮带的重量才能维持在托辊上,故皮带必须有较大的弧线;输送粉尘矿物时,由于囊形皮带可以隔开风流对矿物的作用,所以,它不像普通皮带运输机那样需要防尘保护装置。
From the top of the conveyor to fix the belt, minerals will not leak during transport. This law may seem simple, however, until now developed by Linden-Ali-mak. The transporter is now undergoing trials and will be available to the international mining industry for another year or so. This conveyor has many advantages. It can transport minerals up to 45% (because minerals are trapped inside the belt), whereas conventional conveyors only allow 17% to 18% of the transport grade; Radius of the belt running, the belt can be tighter than the average belt conveyor tension, because the general belt conveyor, only by the weight of the belt can be maintained on the roller, the belt must have a larger arc; conveying dust minerals, as a result of Bag-shaped belts can separate the effect of the wind on the minerals, so it does not require dust-proof protection as ordinary belt conveyors.
