Mobile Mine Mud Treatment Equipment Operation Parameters Optimization Research

摘要: 根据铜坑矿开采过程中所产生的矿井泥浆的性质特点，通过对泥饼含水率、干泥浆产量和固体回收率等测定分析，研究了移动式矿井泥浆处理设备主要运行参数投药量、压滤机滤带移动速度、滤带张力、进泥量以及进泥含水率对泥浆处理效果的影响。结果表明：投药量为3~4 mg/g (PAM/Al2(SO4)3 = 1:1)、滤带移动速度为2~3 m/min、滤带张力为3~3.5 kg/cm2、进泥量为0.8 L/S时，泥浆处理后泥饼呈固态饼状，固体回收率在92%以上，含水率降到40%以下。

Abstract: According to the characteristics of the mine slurry produced in process of Tongkeng Mine, through the determination of filter cake moisture content, dry mud yield and solid recovery rate, it examines the effects of mobile mine mud treatment of main operating parameters of equipment of the dosage, filter press moving speed, belt tension, mud volume and water content of sludge on sludge dewatering. The result shows that when the dosage is 3 - 4 mg/g (PAM/ Al₂(SO₄)₃ = 1:1), belt moving speed is 2 - 3 m/min, belt tension is 3 - 3.5 kg/cm² and mud volume is 0.8 L/S, mud becomes a solid pie after dehydration, solid recovery is above 92% and moisture content is below 40%.
