电耙运搬时,在漏斗门处形成松散矿石的死堆,其参数取决于粉矿的特征,并随放矿进行其高度逐渐增加。在消除漏门处堵塞时死堆又遭到破坏。因此漏门的进矿口高度就稳定在一定范围内。这个范围取决于矿石平均最小尺寸,两者之比为3.0～3.6。 在死堆临界高度的条件下,漏口进路长度(a)与漏门高度(H′)有如下关系:H′=a+1.6。 在一定范围内耙道中矿堆流出长度越大,放矿指标越好。但超过这一范围,电耙巷道将发生堵塞,当电耙設备能力较大时,耙道中矿堆流出长度等于电耙巷道宽度是比较合适的,此时漏口进路长度与漏门高度有下列关系:H′=(a+)tga。 矩形漏门与拱形漏门比较,在放矿强度大和堵塞次数方面是有利的。
When the electric rake is transported, a loose pile of loose ore is formed at the funnel gate. The parameters depend on the characteristics of the fines and gradually increase with the height of the ore. The dead pile was destroyed again when the blockage of the leaky door was eliminated. Therefore, the height of the missed gate is stable within a certain range. This range depends on the average ore size, the ratio between the two is 3.0 ~ 3.6. At the critical height of the heap, the length (a) of the leak mouth and the height of the leak door (H ’) have the following relationship: H’ = a + 1.6. Within a certain range, the greater the outflow length of ore heap, the better the ore discharge index. However, beyond this range, electric rake roadway will be blocked, when the power rake equipment capacity is larger, rake Road mine outflow length is equal to the width of the electrical rake roadway is more appropriate, then the leakage path length and the leakage rate Has the following relationship: H ’= (a +) tga. Rectangular drain and arched door comparison, in the ore mining intensity and plug the number of times is beneficial.
