(2)美國蒂爾登選礦廠。該廠是采用選擇性絮凝陽離子反浮選處理微粒嵌布的低品位鐵礦石。
篩機最高可以達到五層，建議使用三層等。2.嚙角由零變為負值，使物料不僅不會堵塞，反而與直線型動顎板構成較長的“平衡區”，其有效長度為30-60mm，使排料受到一段時間的平行擠壓作用，進一步使物料變細，并且強化了排料，物料到卸料區底部，破碎腔開度增大，加速了排料，從根本上消除了排料的堵塞缺陷，提高了產量。
轉子由主軸圓盤銷軸和錘子組成。電動機帶動轉子在破碎腔內高速旋轉。
3.特殊捕收劑法。對氧化銅礦的浮選，除使用上述兩類捕收劑以外，還可采用其他特殊捕收劑進行浮選。
用途檢定和測定有機化合反應中的鹵素。水分析。

對輥碎石機又稱雙輥碎石機。經濟發展到今天，我國碎石機產業卻面臨著嚴重的產能過剩難題，這不得不引人深入思考。由于我國碎石機技術一直處于低品位階段，與國際發達國家出口品中的高附加值產品比例相比嚴重偏少，長期以往對我國經濟發展十分不利。技術和裝備水平低。
