XJM-S型煤用充气机械搅拌式浮选机
Mechaanical agitating aeration flotation machine for coal

XJM-S(2000)系列浮选机用于浮选-0.5mm粒级各种可浮性煤泥，也可用于浮选其他矿物，现已成为选煤用的主要浮选设备。由于具有独特的入料方式和搅拌机构，优化的流体动力学参数和高选择性分离设计，因此该系列浮选机具有以下特点：①独特的：“”入料方式——“假底底吸、周边串流”，矿浆流态合理，通过能力大，浮选速度快；②双层伞形叶轮设计，空气流道通畅，槽内呈“W型”矿浆流态，可有效降低功耗；③“单控点、双系统进气”，充气效能高，可调范围广（充气速度可调范围在0.5-1.2m3/m2.min),可实现充气量的‘在线'调控；④分体式定子设计，实现叶轮下吸口与吸浆管自然对中，安装精度得到保证；⑤“浸没式中矿箱”使矿化气泡与排出的矿浆逆向运动，可提高分离精度；⑥粗度级的浮选效果优于同规格其他类型的浮选机（柱），对细粒级的选择性高，可获得优质浮选产品，精煤回收率高；⑦能耗和药耗低，浮选机装机及实耗功率均小于国内外同类型同规格的其他浮选机；⑧优质耐磨材料，叶轮和定子使用寿命长；⑨占地面积小，运转可靠，操作维护方便，维护量小等优点。

XJM-S (2000) flotation machines are used for the flotation of various floatable coal slimes with particle size of 0.5mm, or used for the flotation of other minerals. They have now become main flotation equipment for coal dressing. As they adopt unique feeding methods and agitating mechanism, optimized fluid dynamics parameters and high selectivity separation design, flotation machines of such series have the following features: ① Unique feeding method: “suction at bottom and series flow around”; reasonable flow state of slurry, large passing capacity; and fast flotation speed; ② Double-layer umbrella-like impeller design, unblocked air flow passage, and “W shape” slurry flow state in the tank which are able to effectively reduce power consumption; ③ “Single control point, double system air induction”, high aeration efficiency, wide adjustable range (the adjustable range of aeration rate is 0.5-1.2m3/m2.min), realizable online regulation of aeration quantity; ④ Split-type stator design; natural centering of impeller lower suction and sipper is realized; installation accuracy is ensured; ⑤ “Submerged middling box” enables mineralized bubbles and discharged slurry to move reversely which can improve separation precision; ⑥ Flotation effects of coarse graded ones are superior to flotation machine (column) of the same specification but other types. Its selectivity of fine-graded ones is high and superior flotation production can be obtained. The clean coal recovery rate is high. ⑦ Its energy consumption and reagent consumption are low. The installation power and actual power consumption of flotation machine are both smaller than those of other flotation machines of the same type and the same specification at home and abroad. ⑧ Superior abrasion resistant materials and long service lives of impellers and stators; ⑨ Small occupied area, reliable operation, easy for operation and maintenance, less maintenance, etc.
