“谷底角”——由矿仓、漏斗,或者溜槽的两边墙的交线所组成——必须大子在容器内的原料的安息角或原料不会流动的角度。此谷底角常小于两边墙的任一边墙角。可用下列方程式计算。cot~2V=cot~2α+cot~2β此处V是谷底角,α和β是两个边墙角,均以度数计。利用谷底角计算图表(附图)能迅速解答此 The “corner angle”—consisting of the intersection of the bunker, the funnel, or the two sides of the chute—must be the angle of repose of the raw material in the container or the raw material does not flow. This corner of the valley is often smaller than the corners of either side wall. It can be calculated using the following equation. Cot~2V=cot~2[alpha]+cot~2[beta] where V is the bottom angle, and [alpha] and [beta] are two side wall angles, all in degrees. Use the bottom corner calculation chart (drawings) to quickly answer this
