石英砂中大顆粒色選機參數
色選機(ji)是一種(zhong)利用物料的光(guang)學(xue)(xue)及色度學(xue)(xue)特性(xing),將顏色不正常(chang)或(huo)表面有缺陷(xian)的次品(pin)及雜物從物料中無(wu)損檢(jian)出,并自動分(fen)(fen)(fen)選剔除的新(xin)型(xing)機(ji)械,它綜合應用了電(dian)子學(xue)(xue)、生物學(xue)(xue)等新(xin)技術(shu)(shu),是典型(xing)的光(guang)、機(ji)、電(dian)一體化的高新(xin)技術(shu)(shu)設(she)備。目前國內色選機(ji)市(shi)場(chang)以(yi)日本,韓(han)國,意大(da)利等國產品(pin)為(wei)主,大(da)多數為(wei)光(guang)電(dian)管色選機(ji),量是 ccd 色選機(ji). 無(wu)論從技術(shu)(shu)發展(zhan)還是市(shi)場(chang)需求的角度來考(kao)慮,對(dui) ccd 色選機(ji)的研究都有著非常(chang)重要(yao)的意義。因(yin)此(ci)筆者對(dui)以(yi) ccd 為(wei)檢(jian)測元件(jian)的色選機(ji)分(fen)(fen)(fen)選控(kong)制(zhi)系(xi)統(tong)(tong)(tong)(tong)進行了實驗研究,分(fen)(fen)(fen)選控(kong)制(zhi)系(xi)統(tong)(tong)(tong)(tong)主要(yao)分(fen)(fen)(fen)為(wei)兩個部分(fen)(fen)(fen): ccd 檢(jian)測系(xi)統(tong)(tong)(tong)(tong)和分(fen)(fen)(fen)選系(xi)統(tong)(tong)(tong)(tong)。此(ci)系(xi)統(tong)(tong)(tong)(tong)極(ji)大(da)地提高了信號處(chu)理的分(fen)(fen)(fen)辨(bian)率和準確性(xing)。
