Agitation Equipment should be set in a flat position, the front and rear axles cushioned with square wood, so that the overhead tires, so as not to move during the move. Blender should implement two leakage protection, power before work, must be carefully examined by the empty car test turn qualified, can be used. Test run should be tested drum speed is appropriate, under normal circumstances, the empty car speed slightly faster than after loading 2-3 turn, if the difference is more, you should adjust the ratio of moving wheels and drive wheels.
Principles of fluid motion and turbulence which have been found to be of use in mixing and agitation problems are discussed, as well as suggested applications in extractive-metallurgy processes. Various types of impellers are described, together with other conditions that affect flow pattern and turbulence.
The choice of equipment for particular requirements is considered, and equations for power input are given. Modern heavy-duty mixing and agitation equipment can take an increasingly important part in such extractive-metallurgy processes as solids handling, crystallizing and leaching, chemical operations, and flotation. Application of mixing and fluid-mechanics principles to extraction methods can lead to greater process rates and a resultant saving in time and money.
In the production of paper, the ground fibrous mass is mixed with water, thereby forming a suspension. After stirring and the removal of mechanical impurities, the suspension is subjected to Thickening Equipment to shipment to the factory. In wet concentration of ores, a pulp is formed, which consists of a concentrate and 40–60 percent water. Since the water content in the concentrate shipped to the factory should not exceed 5–15 percent, the pulp is first thickened, which reduces the water content by a factor of 1.5–2, and then dehydrated, which results in an almost total removal of water. When dredges are used to work gravel deposits containing sand, the content of the material in the pulp is 3–6 percent by volume.
