Role of material field:
选矿厂的配矿以及混匀料场有如下作用:
The ore dressing plant and the mixing field have the following functions:
1贮存作用。由于料场有一定的矿石贮存量,把它用作贮存设施,保证对选矿厂提供足够的矿石。料场起到调节和缓冲作用的相互干扰,运输不及时的影响因素可以基本消除,这就是保证选矿厂可以在正常调节下进行连续生产,
1 storage. Because the material field has a certain amount of ore storage, it is used as storage facilities, to ensure that the ore dressing plant to provide enough ore. The material field plays a role in the regulation and the buffer function of the mutual interference, the transportation is not timely and the influence factor can be basically eliminated, this is to ensure that the ore dressing plant in the normal regulation of continuous production,
2配矿与混匀作用。对进入料场,的矿石,用适当的堆料方式和布料方法,选用合适的堆料和取料设备,使矿石在在化学组成和物理性质方面得到混匀,入选矿石的质量得到稳定,生产操作和管理得到改善。
2 ore blending and mixing. To enter the yard, ore, with proper stacking method and distribution method, choose suitable stacker and Reclaimer equipment, so that ore in chemical composition and physical properties of mixed evenly in the selected ore quality stable, and production operation and management has been improved.
料场的布置方式主要是根据用料来那个、场地以及、总图布置和选用的堆料等因素决定。采用传来呢直线式则布置成一跨两堆制。这些形式各有优点。
Layout of the material field is mainly determined according to the materials to the site, and the general layout and selection, stacking and other factors. The use of a straight line is arranged into a cross two pile system. These forms have their advantages.
选用的堆料机和取料机类型与料场布置方式有着模切的关系、
The stacker and Reclaimer type and material field layout with cutting relationship,
当选用固定式悬臂皮带堆料机时,料场可以按两跨两堆制布置,若一台取料斗要取两垮的料堆,由于取料设备不能直接过跨或过堆,当要过跨时,就要用过跨小车的办法。
When using fixed cantilever belt stacker feeder, material field can according to two cross two piles of layout, if a reclaiming bucket to take two loose material pile, due to the reclaimer equipment can not be directly cross or heap, when to cross, used car across the way.
选用双向把料的桥式取料机,其颤抖可以条换方向,可以将料场分布为每跨两对侧,具体形式有一跨两堆式、四跨四堆式,取料机设置在两个料堆之间、取料时可以向两个方向取料。
Choose two-way the material of bridge type reclaimer, their trembling can be a change of direction, may the material field distribution for each span two pairs of side, the specific form is a two span pile type and 4 spans four heap, reclaimer set in the two material stack and Reclaimer can to two direction reclaimer.
圆形料场:
Circular material field:
圆形料场堆料时,矿石由设置在栈桥上的皮带运输机运来,通过堆场中心的旋转的漏斗将矿石卸至径向的回转式堆料的皮带机上进行布料。堆料皮带机应是可俯仰的,以减少粉尘的污染。取料通常采用桥式扩版取料机。取料机的桥架一段支承在堆场中心的主柱上、另一端支承在料堆外圆的圆形轨道上。
Circular material field stacker ore by set at the trestle on belt conveyor to transport, through the yard the center of rotation of the funnel will ore unloading to the radial rotary pile material belt cloth. The pile belt conveyor should be available to reduce dust pollution. Usually the bridge reclaimer reclaimer expanded edition. Reclaimer bridge a bearing in the yard the center's main column, the other end is supported in the heap of the outer circle of circular orbit.
圆形料场的外圆直径在45-100米之间,最大为150米,但在使用中多为85-100米。
The outer circle diameter of the circular material field is between 45-100 meters, the maximum is 150 meters, but in the use of more than 85-100 meters.
