| Abstract: | The development of a new pulp height monitor is discussed in this paper. The conductivity of pulp,froth and air in the floatation cells are obviously different through the research on the site. According to the principle that the different media have different conductivity, new pulp height monitor has been designed.This monitor consists of multi electrode sensor,sensor circuit and 8031 Single Chip Microco mputer. This monitor can determine the dividing line between the pulp and froth,the depth of froth in the floatation cell. The pulp monitor can be used in the automatic controlling of coal flotation. |
