為解決特殊分配曲線的特性參數(shù)難以客觀評(píng)價(jià)選煤設(shè)備分選性能的缺陷,提出了3種獲取高密度段平均密度的技術(shù)途徑,即實(shí)測(cè)法、回歸法和查圖法,根據(jù)重選設(shè)備工藝性能評(píng)定的試驗(yàn)資料統(tǒng)計(jì)結(jié)果,給出了不同高密度段平均密度選取的經(jīng)驗(yàn)值。

Various methods of parallel moving for partition curve of gravity separation with different densities were discussed.

針對(duì)重力分選中不同分選密度下分配率的變化狀態(tài),討論了不同分配曲線模型平移的方法,建立了復(fù)合雙曲正切模型函數(shù)的平移公式,給出了幾個(gè)常用分配曲線模型的理論平移公式,并對(duì)它們的正確性進(jìn)行了驗(yàn)證。

The equipment's separation density obtained by using partition curve method was 1.

對(duì)煤炭雜物分離設(shè)備的實(shí)際分離效果進(jìn)行了試驗(yàn)研究 ,利用分配曲線法 ,得出該設(shè)備的分離密度為 1。

Based on the results of the analysis, a mathematical model of the screen is established with piecewise function to describe completely the partition curve of the probability sizing.
