浮选机在选矿行业应用广泛类型多样，但不管什么机型都有一个事故闸门（其结构如图1所示）。一般事故闸门构件达8件之多，不但制造加工费时费力，使用也很不方便，特别是丝杆变形后，闸门就关闭不严泪水漏矿。因此，我们根据生产中的需要，对其分别进行改造。1小容量浮选机槽I Flotation machines are widely used in the mineral processing industry, a wide range of types, but no matter what the model has an accident gate (the structure shown in Figure 1). General accident gate components up to 8 as much, not only manufacturing and processing time-consuming and laborious to use is also very inconvenient, especially after the screw deformation, the gate closed lax tears leak ore. Therefore, according to the needs of our production, we have to reform them separately. 1 small capacity flotation tank I
