Abstract
The invention discloses a kind of Novel super-thin cement production process, which is with a kind of New Grinding Devices --- steam flour mill is crushed to 10 microns of particle diameter, and superfine cement is made by ordinary cement.Superfine cement early strength made of the technology of the present invention is high, one day flexural strength 5.5MPa, one day compression strength 25MPa.
Description
Technical field
The present invention relates to a kind of Novel super-thin cement production process
Background technology
Cement deposit material was applied since 1838 Britain's Thompson tunnel, and people have found ordinary cement particle diameter in practice
Larger, penetrating power is limited, can only generally penetrate into crack or gap more than 0.1 millimeter, and is reinforced for fine crack grouting
Effect is poor.Therefore the research of chemical slip casting material is turned to, since the price of chemical slip casting material is high, formula is complicated, Er Qie great
Most chemical slip casting materials are poisonous, its development is restricted.In order to improve the property noted of cement, ultra-fine water in low osmotic medium
Mud injecting paste material is into hot spot.Data at home and abroad all thinks that superfine cement maximum particle diameter answers 20 microns of ＜（It is micro- to be often referred to D95 ＜ 20
Rice, it is allowed to have 20 microns of 5% ＞）.
The production technology of current superfine cement relies primarily on the continuous of traditional mechanical force such as impact, grinding, extruding, bending
Collective effect, makes the fineness during being progressively crushed of the coarse granule in cement drastically decline, superfine cement is made.Such a life
Production. art high energy consumption, metal material abrasion are big, and production cost is very high.This project it is innovative develop a kind of superfine cement
Production Technology, the steam that electricity is distributed using thermal power plant is power, in special mill body（Steam flour mill）It is interior, will be through
Ball mill coarse crushing to less than 0.3 millimeter of cement granules hit mutually, grind stripping into ultra-fine grain, the ultra-fine choosing through flour mill top
Powder machine sub-elects 10 microns of superfine cements of particle diameter ＜, into product collector；Cement granules of the particle diameter more than 10 microns continue
Crushed in mill.50 kilowatt-hours of superfine cement ton power consumption, ton steam consume 2 tons.Production cost is greatly reduced.
The content of the invention
The purpose of this technology is using steam flour mill production superfine cement.10 microns of product maximum particle diameter ＜（D95 ＜ 10
Micron）, compression strength reaches 25MPa within one day, produces superfine cement more excellent performance than Conventional processing methods, production cost is more
It is low, it is the optimal manufacturing technique method of superfine cement.
A kind of Novel super-thin cement production process, is realized using following steps：
1st, clinker, gypsum, active mixed material are matched by the requirement of national standard ordinary cement, are crushed in the ball mill
Less than 0.3 millimeter, in the bistrique storehouse through Geldart-D particle to steam flour mill.
2nd, above-mentioned material is uniformly fed in steam flour mill by metering screw conveyer, is milled into the ultra-fine of 10 microns of ＜
Cement.
3rd, steam flour mill is the superheated steam that 1.0~1.3MPa, 270 DEG C of power plant are distributed to electricity, by right in mill body
In the nozzle spirt flour mill of title, material particles are cast and hits mutually, grind stripping into ultra-fine grain, qualified product is through mill
The superfine powder sorting machine on body top sub-elects, and is collected into product collector；Underproof particle continues to crush.
4th, product collector collects superfine cement, is transported to by Pneumatic conveying pipeline in finished bin.
The advantages of the present invention
The art of this patent makes full use of the superheated steam after the power generation of thermal power plant to carry out comminuting matter as kinetic energy, realizes resource
Regeneration, unit of the product power consumption is low, and production cost is greatly lowered, and product more has market competition advantage, can guide more
Enterprise using this production technology production superfine cement.The Showcase Production Line produced as energy-saving and emission-reduction, low-carbon.Utilize this technology
The superfine cement function admirable produced, intensity are high.
