Problems solved by technology

[0009] At present, the control of grinding concentration and particle size is generally operated by skilled workers and manually adjusted according to the data measured by the instrument. The disadvantages are that the control accuracy is not enough, the response speed is slow, the labor intensity is high, and the effect is poor.

Embodiment Construction

[0039] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, but not to limit the present application.

[0040] figure 1 It is a schematic diagram of the grinding process involved in the embodiment of the present invention.

[0041] like figure 1 As shown, in a preferred embodiment, the ore feeding device is a heavy plate type ore feeder 1 . The grinding process is roughly as follows:

[0042] The heavy-duty apron feeder 1 feeds the ore to the No. 3 belt 2, and the actual ore feeding amount is measured by the belt scale 3. The ore is transported into the semi-autogenous mill 5 through the No. 3 belt 2. The semi-autogenous mill 5 is provided with a semi-autogenous mill water adding valve 4 at the feed end. The actual water supply is measured by the semi-autogenous mill water adding valve flo...

Abstract

The invention provides a system for controlling grinding density and fineness as well as a method for controlling grinding density and fineness. The system for controlling grinding density and fineness comprises an interface operation unit, a detection unit, a central data processing unit and a PID control unit, according to a comparison result of the central data processing unit, ore-feeding amount of an ore-feeding apparatus, water supply volume of a water supply apparatus and frequency of a slurry pump at upstream of a cyclone can be controlled, so that actual overflow concentration and the actual overflow granularity is in a set overflow concentration set parameter and overflow granularity set parameter scope. The invention also provides a method for controlling grinding density and fineness, which comprises the following steps: preseting, detecting, processing, controlling grinding density and controlling the grinding granularity. By using the system for controlling grinding density and fineness as well as the method for controlling grinding density and fineness, concentration and granularity of pulp through grinding can be effectively controlled, effect is rapid, and operation is simple.

Description

technical field [0001] The present application relates to the field of ore dressing, in particular to a grinding ore concentration and fineness control system and a grinding ore concentration and fineness control method. Background technique [0002] The grinding part is a very important part of the beneficiation part, and the quality of the grinding operation index directly affects the stability of the flotation index of the next level of beneficiation process. Therefore, stable control of grinding concentration and particle size indicators plays a very important role in beneficiation production. [0003] Particle size control is more important than concentration control, because particle size has a greater impact on flotation, so stable particle size control is more meaningful than concentration control. Theoretically speaking, the higher the particle size control of the cyclone overflow, the better, too high, of course, will be disadvantageous to flotation. In actual ind...
