Abstract
According to the request of the intruction of plant design for undergraduated, the design of Huangshaping Pb -Zn Mine concentrator with the capacity of 1750t/d, and the products are lead and zinc concentrate.
On the basis of practice in Huangshaping Pb -Zn Mine for three weeks, and the collection of data, The work institutions of each workshop were determined, and the technological process was also chosed and reasoned The process of crushing is three sections with half open circuit, the grinding process is one section with closed circuit, the floation process is selective flotation of lead minerals, and a process with two sections dewatering circiut which included concentration and filtion was adopted .
Technological parameters of crushing,screening, grinding ,floation(include the circuit of pulp)and dewatering were computed, respectively. Then the technological parameters of equipments were computed and the schemes of equipments were compared and the optimal equipments were determined.
The general arrangement of concentrator plant and the allocation of equipments in diferent workshop were presented. According to the topography of plant site, plants were arranged along the slope of mountain. The workshops of coarse crushing, middle and fine crushing and screening were aloted independent. Arrangment with parallel contour line of coarse crushing workshop、 middle and fine crushing and screening workshops were used. The workshops of grinding and flotation were put togather, and the longitudinal and lateral plans were used for the mills and flotation machines respectively. The concentrate machines were collocated seprarted from thefilitering workshop and concentrate bins which were aloted inside. 10 pieces drawing ,such as the workshop of coarse crushing, middle and fine crushing, screening , grinding , floation , dewatering and so on, were finished include a handicraft drawing.
