Abstract
The invention relates to a lime milk additive preparation system. The unit consumption of lime on a production operation site is determined as 5 to 15kg/t according to the properties of treated crude ores; 10 weight percent lime milk is prepared; specifications of an electric vibration feeder, a stirring barrel and a sand pump are determined according to the production scale of the ore dressing site; the proper site is selected and collocated according to a height difference of 2 to 5 meters; and the feeding quantity of the electric vibration feeder controlled by a time relay is regulated according to the consumption of the added lime in the production process.
Description
Technical field
The invention belongs to the mining equiment technical field, relate to the used milk of lime of a kind of pyrite ore dressing and add preparation system.
Background technology
Lime is the important beneficiation reagent in nonferrous metallurgy mine, it is one of pyritous inhibitor, it rationally adds very important to the raising of ore dressing production target, the addition manner of pulverulent lime has two kinds: the one, and adopt cradle feeder directly to add, another kind is to add after making milk of lime, adopts to make and adds the effective utilization that more helps lime and the ordinary production of ore-dressing practice behind the milk of lime.As shown in Figure 1, traditional pulverulent lime adding method is after feed hopper 1 discharging, directly adds to adhesive tape conveyor 3 through cradle feeder 2, has easily stifled and consumption shortcoming more rambunctious.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of lime concentration of production operation easy to control and consumption and the milk of lime that operation is simple and add preparation system.
The present invention solves the technical method that its technical problem adopts: a kind of milk of lime adds preparation system, according to the character of handling raw ore, the lime specific consumption of determining the production operation scene is 5-15kg/t, be mixed with weight percent concentration then and be 10% milk of lime, again according to the production scale of ore dressing field, determine the specifications and models of electric vibrating feeder, agitator and sand pump, select suitable place to be configured, adjust the feeding coal of the electric vibrating feeder of controlling with the time relay in process of production according to the lime consumption that adds by the discrepancy in elevation of 2-5m.
Described production scale is the ore dressing field of 200t/d, and the lime specific consumption is 5kg/t, and selecting the electric vibrating feeder model is that GZ1, agitator ￠ 2000mm, sand pump model are 2PN.
Described production scale is 200t/d ore dressing field, and the lime specific consumption is 5kg/t, and the lime addition is 42kg/h.
The invention has the beneficial effects as follows: adopt electric vibrating feeder, agitator and sand pump that pulverulent lime is made milk of lime and add, the lime concentration and the consumption of the production operation more easy to control of this method, operation is simple.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram.
Fig. 2 is a structural representation of the present invention.
Among the figure: 1-feed hopper, 2-cradle feeder, 3-adhesive tape conveyor, the 22-time relay, 23-electric vibrating feeder, 24-agitator, 25-sand pump.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Referring to Fig. 2, a kind of milk of lime adds preparation system, the pulverulent lime raw material from feed hopper 1 feeding to electric vibrating feeder 23 by the time relay 22 control, stir to the agitator 24 by electric vibrating feeder 23 feedings again and make milk of lime, after the scene adds the snack made with traditional Chinese medicines dosing, be delivered to the ore dressing field then by sand pump 25.
According to the character of handling raw ore, the lime specific consumption of determining the production operation scene is 5-15kg/t, be mixed with weight percent concentration then and be 10% milk of lime, determine the specifications and models of electric vibrating feeder, agitator and sand pump, as production scale is the ore dressing field of 200t/d, the lime specific consumption is 5kg/t, selecting electric vibrating feeder GZ1, agitator ￠ 2000mm, sand pump model is 2PN, the sand pump model is that 2 among the 2PN is meant pump discharge diameter (inch), P is meant transh pump, and N is meant mud.Select suitable place to be configured by the discrepancy in elevation of 2-5m, adjust the feeding coal of the electric vibrating feeder of controlling with the time relay in process of production according to the lime consumption that adds, as 200t/d ore dressing field, lime specific consumption is 5kg/t, then the lime addition is 42kg/h, carry out the normal operation work of whole system equipment, guarantee carrying out smoothly of production.Though the present invention increases the equipment component input, equipment operation simultaneously and maintenance cost increase to some extent, but guaranteed the stability of production operation lime consumption, reduce greatly because the influence that lime feed instability causes ordinary production, help improving beneficiating technology index and economic indicator, select factory rules and regulations mould year to create 200,000 yuan of economic benefits by 200t/d.
Claims (3)
1. a milk of lime adds preparation system, it is characterized in that: according to the character of handling raw ore, the lime specific consumption of determining the production operation scene is 5-15kg/t, be mixed with weight percent concentration then and be 10% milk of lime, again according to the production scale of ore dressing field, determine the specifications and models of electric vibrating feeder, agitator and sand pump, select suitable place to be configured, adjust the feeding coal of the electric vibrating feeder of controlling with the time relay in process of production according to the lime consumption that adds by the discrepancy in elevation of 2-5m.
2. milk of lime as claimed in claim 1 adds preparation system, and it is characterized in that: production scale is the ore dressing field of 200t/d, and the lime specific consumption is 5kg/t, and selecting the electric vibrating feeder model is that GZ1, agitator ￠ 2000mm, sand pump model are 2PN.
3. milk of lime as claimed in claim 1 or 2 adds preparation system, and it is characterized in that: production scale is 200t/d ore dressing field, and the lime specific consumption is 5kg/t, and the lime addition is 42kg/h.
