Problems solved by technology
Due to the inevitable generation of solid particles in the preparation process of the calcium oxide chemical solution, the solid particles not only cause the loss of active ingredients in the calcium oxide chemical solution, thereby affecting the flotation effect, but also the solid particles can easily block the equipment such as adding pipes and valves Parts cannot guarantee the normal addition of chemicals, resulting in a sharp and rapid decline in the grade of flotation iron concentrate

The invention belongs to the technical field of particles screening and grinding, and in particular relates to a device for screening, grinding and adding particles of a calcium oxide chemical in flotation. The device is characterized by comprising two slewing supporting devices which are arranged at the top of a middle chemical storing case, a rotary screen drum which is arranged between the two slewing supporting devices and is located in a chemical feeding port of the middle chemical storing case, and a chemical feeding pipe and a reflux pipe which are respectively communicated and connected with the middle of the rotary screen drum. The device is simple in structure and light in weight, and is unnecessary to additionally arrange a driving device, thereby reducing the energy consumption. According to the device, the solid particles in a calcium oxide chemical solution are effectively ground and screened, so that the solid particles are finer and the effective utilization rate is improved, and therefore, the concentration and the granularity of preparing the calcium oxide chemical solution are guaranteed.
Description
technical field [0001] The invention belongs to the technical field of particle sieving and grinding, and in particular relates to a particle sieving and grinding adding device of calcium oxide agent in flotation operation. Background technique [0002] Calcium oxide is widely used in many iron ore beneficiation plants as an activator in the flotation process. In the production site, the prepared calcium oxide solution is generally pumped out from the dispensing box and sent to the intermediate storage box, and then sent from the intermediate storage box to the dosing box to enter the flotation operation. In the flotation process, there are strict regulations and restrictions on the concentration and dosage of calcium oxide reagent solution. Due to the inevitable generation of solid particles in the preparation process of the calcium oxide chemical solution, the solid particles not only cause the loss of active ingredients in the calcium oxide chemical solution, thereby aff...
