下面就簡單的介紹一下制砂生產線工藝中的三種制砂工藝。砂生產線之濕法生產;濕法制砂生產線是指三級破碎段全部采用濕法制砂生產線工藝。其特點是：可以有效的保證人工骨料成品質量，對石粉含量和含泥量可控制，降低了生產過程中的粉塵量，但系統用水量大，運行成本高，部分細砂，石粉流失，回收率較低，廢水處理量大而且效果不太理想。另外，若進入立軸沖擊式破碎機的骨料含水率超標，容易導致破碎腔結塊堵塞，降低設備成砂率，甚至發生轉子抱死的機械事故。干法制砂生產線干法制砂生產線是指幾個破碎段全部采用干式生產工藝。其特點是：無供水裝置。生產工藝簡化，可節約系統建造投資和運行成本，但對巖石中的泥土含量難以控制，而且系統粉塵污染嚴重。干法制砂生產線半干法制砂生產線結合了濕法制砂生產線和干法制砂生產線的優點，即粗碎采用濕法生產，可有效去除原料中的泥土，降低粉塵排放；中細碎和中碎（僅有兩個破碎段）采用干法生產，棒磨機制砂采用濕法生產，通過洗砂與脫水工藝調節成品砂的細度模數、石粉含量及含水率。
調節閥選型的原則根據工藝條件，選擇合適的結構形式和材料。根據工藝對象的特點，選擇調節閥的流量特性。根據工藝操作參數，選擇合適的調節閥口徑尺寸。根據工藝過程的要求，選擇所需要的輔助裝置。合理選擇執行機構。執行機構的響應速度應能滿足工藝對控制行程時間的要求：所選用的調節閥執行機構應能滿面足閥門行程和工藝對泄露量等級的要求。在某些場合，如選用壓力調節閥(包括放空閥)，應考慮實際可能的壓差進行適當的放大，即要求執行機構能提供較大的作用力。
一般水泵的銘牌上都提到允許吸上真空高度或必需汽蝕余量NPSHr，就是根據水泵在額定轉速和流量下而又不產生汽蝕為原則，由制造廠試驗所確定的大吸水高度，為了不發生汽蝕而限制了水泵葉輪進口處的壓力不能低于某一數值。也就是說，水泵葉輪進口處的真空度不能高于某一數值。通常又把水泵葉輪進口處允許的低壓力，也叫水泵的允許吸上真空度，它與允許吸上真空高度是一回事。汽蝕的防止措施屏蔽泵的實際安裝高度，必須低于或等于水泵的實際吸水高度。
FFU的外觀目前，全世界所有廠家生產的FFU，從外觀上可這樣劃分:從形狀上分兩種，一種是長方體（如圖1所示），一種上部為坡形（如圖2所示）。圖2所示的FFU的上部做成坡形，起到了一種導流的作用，有利于氣流的流動和均勻分布。圖1所示的FFU則一般依靠另外的途徑來均衡氣流。從結構上分兩種，一種為整體（如圖3所示），一種為分體（如圖4所示）。分體形狀的FFU有如下優勢：使過濾器的更換變得方減小了安裝過程中的勞動強度。
