本发明公开了一种微粉生产新工艺，其特征在于含有以下工艺步骤：(1)原料经除铁输送至矿石超细粉碎机上方的稳料仓后均匀进入矿石超细粉碎机；(2)原料经矿石超细粉碎机多次抛升冲击后，含有60％～80％合格微粉(比表面积≤420m2/kg)的半成品经倒置锥形筛进入半成品密封通道；(3)半成品密封通道与密封的斗式提升机将半成品物料输送到气流分级机；(4)气流分级机将半成品分选为合格品和不合格品，合格品被气流送入成品库，不合格品经回管再次进入矿石超细粉碎机；(5)各进出料接口安装除尘抽风罩，除尘器收聚的细粉排入成品库。本工艺过程简捷，占用面积小，设备投入少，能耗是现有工艺的1/3，节能减排效果显著。
The invention discloses a new process for producing micropowder, which is characterized in that it contains the following process steps: (1) raw materials are transported to a stabilizing bin above the ore ultrafine pulverizer after iron removal, and then uniformly enter the ore ultrafine pulverizer; (2) After the raw materials are thrown and impacted by the ore superfine pulverizer for many times, the semi-finished product containing 60% to 80% qualified micro powder (specific surface area ≤ 420m 2 /kg) enters the semi-finished product sealed channel through the inverted conical sieve; (3) The semi-finished product sealed channel and The sealed bucket elevator transports the semi-finished products to the air classifier; (4) The air classifier separates the semi-finished products into qualified products and unqualified products. The qualified products are sent to the finished product warehouse by the air flow, and the unqualified products enter again through the return pipe Ore ultra-fine pulverizer; (5) Each inlet and outlet interface is equipped with a dust removal exhaust hood, and the fine powder collected by the dust collector is discharged into the finished product warehouse. The process is simple, occupies a small area, requires less investment in equipment, consumes 1/3 of the existing process, and has remarkable energy-saving and emission-reduction effects.
Description
Technical field
The present invention relates to the energy-conserving and emission-cutting technology field, in the micro mist production process, use new energy-saving equipment specifically; Optimization production technology; Directly with the precomminution system as whole crushing system, the cancellation high equipment such as ball mill of energy consumption that have high input reach energy-saving and emission-reduction; Reduce and drop into the purpose of optimizing the environment.
Background technology
In the present prior art; China's the most representative current technique for producing miropowder flow process is roll squeezer (also can be a tin roller mill or a vertical mill) and the technological process of ball mill combination grinding: material through roll squeezer extruding pulverize (or tube roller mill or vertical abrasive dust broken) afterwards; Break up sorting through the scattering and grading machine, (particle diameter≤2mm) is sent into the ball mill grinding system to fines; Coarse fodder (particle diameter is more than 2mm) returns roll squeezer and pushes once more, and the ball mill grinding goes out finished product and directly puts in storage.Also have and use the two-stage grinding machine to roughly grind the associated working situation with fine grinding respectively.The capacity usage ratio of ball mill has only about 3%, and therefore, the power consumption of one ton of micro mist of every production is at 40kw/h to 80kw/h.And because complex manufacturing causes dust discharge point many, dust collecting system is complicated, causes environmental pollution serious, and production cost is high.
Summary of the invention
Content of the present invention is that the shortcoming to above-mentioned prior art exists proposes a kind of new technology process of using new equipment.Directly with the precomminution system as whole crushing system, the cancellation high equipment such as ball mill of energy consumption that have high input reach energy-saving and emission-reduction, reduce and drop into, the purpose of optimizing the environment.
Use new equipment ore ultrafine crusher, and with it directly as the new technology of whole crushing system, the power consumption of one ton of micro mist of every production is controlled in the 20kw/h.
The present invention realizes through following concrete technical scheme: it is characterized in that containing following processing step:
(1) the steady feed bin of powder material above deironing is delivered to the ore ultrafine crusher evenly gets into the ore ultrafine crusher through current stabilization;
(2) powder material through the ore ultrafine crusher repeatedly throw rise impact after, the semi-product material that contains 60%～80% qualified micro mist gets into the semi-finished product seal channel through the inverted-cone shape sieve;
(3) bucket elevator of semi-finished product seal channel and sealing is transported to gas flow sizing machine with semi-product material;
(4) gas flow sizing machine is elected the semi-product material branch as certified products and defective work, and certified products are sent into accurate warehouse for finished product by air-flow, and defective work gets into the ore ultrafine crusher once more through the coarse fodder return pipe and carries out closed cycle;
(5) each material inlet and outlet connectors is installed dedusting suction opeing, is entered accurate warehouse for finished product by the fine powder of deduster pinching, after the certified products stirring homogenizing that accurate warehouse for finished product and gas flow sizing machine sub-elect, gets into warehouse for finished product.
The described steady feed bin of step (1) directly places the top of ore ultrafine crusher, and powder material directly gets into the ore ultrafine crusher through constant-current stabilizer.
The maximum gauge of the material of the described entering ore of step (2) ultrafine crusher should be less than 20mm, and the material after the ore ultrafine crusher is pulverized after the speed of using frequency converter adjustment inner and outer rotors, has 60%～80% material to reach specific area 420m
2During/kg, just should discharge, to guarantee the optimum point of production and the optimum state of equipment as semi-finished product.
The described semi-finished product of step (4) directly use closed cycle after gas flow sizing machine is with the semi-product material sorting, equipment such as ball mill or Vertical Mill or roll extrusion mill no longer are installed thereafter.

Among the figure: 1-deironing charging, 2-raw material elevator, 3-ore ultrafine crusher, 4-current stabilization storehouse, 5-gas flow sizing machine, the accurate finished bin of 6-, 7-coarse fodder return pipe, 8-finished bin, 9-semi-finished product elevator, 10-semi-finished product seal channel, 11-deduster, 12-deduster blower fan
The specific embodiment
Shown in Figure 1 is technology arrangement figure of the present invention; Powder material is carried (1) to raw material elevator (2) after deironing; Current stabilization evenly gets in the ore ultrafine crusher (3) through current stabilization storehouse (4), through the ore ultrafine crusher repeatedly throw rise impact after, the semi-product material that contains 60%～80% qualified micro mist gets into semi-finished product seal channels (10) through the inverted-cone shape sieve; Get into semi-finished product elevators (9); Be promoted to gas flow sizing machine (5), after gas flow sizing machine (5) sorting, defective coarse fodder gets into the ore ultrafine crusher once more through coarse fodder return pipe (7) and carries out closed cycle; Certified products are then sent into accurate warehouse for finished product (6) by air-flow; Simultaneously, each material inlet and outlet connectors is equipped with the dedusting suction opeing, gets into deduster (11) through pipeline, and the qualified gas after its dedusting enters sky through exhaust blower (12).The fine powder that deduster is collected then gets into accurate warehouse for finished product (6), gets into warehouse for finished product after the certified products that sub-elect with gas flow sizing machine stir homogenizing.
