Abstract
This invention discloses technique to increase yield and quality when it grinds the plant in open flow system, which is characterized in that, slow releasing solid grinding aid with cool water with pH value of 6~8 at temperature below 25Deg, preparing liquid grinding aid on field, and adding into grinder with controlled precise quantity. With the technique, it can increase whole effect 10~25% for three grinders; it can control precisely the hole sizer of fineness 4900 when residual is 1.5~5.0%, and the special surface area 320~450m2/kg; the temperature when cement prepared can decrease 10~20Deg; it increases the special surface area with 10~40m2/kg and early strength with 0.5~1.5MPa for same condition separately.
Description
Affiliated technical field
The invention belongs to a kind of new technology of processing cement, is the technology that streaming system mill output and quality are opened in a kind of raising particularly.
Background technology
In general, driving the streaming system grinding tool has technology arrangement simple, advantage such as equipment is few, reduced investment, maintenance cost are low.But bigger shortcoming is also arranged: be exactly that to wrap ball, bag section, Electrostatic Absorption serious, it is many to cross the grinding phenomenon, low during platform, power consumption is high, go out to grind the cement temperature drift, fineness, specific area should not be controlled.At present, a kind of solution being arranged is to make the mill efficiency of each kind cement reach best by adding grinding aid.Yet the grinding aid that uses all is to adopt liquid state now, directly transports to construction ground by manufacturer and uses.The weak point of its existence is: transportation is inconvenient, and grinding aid concentration is fixed, can not regulate as required, and result of use is not best.
Summary of the invention
The present invention's purpose is to provide a kind of raising to open the new technology of streaming system mill output and quality, and it has overcome the above-mentioned deficiency of prior art, and is easy to operate, and result of use is good.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: with pH value is the following cold water extended release solid grinding aids of 6～8 clean 25 degree, and the scene is made liquid grinding aid and accurately controlled the size and add grinding machine and get final product.
PH value is 6～8, clean pure cold water utilizes valve and flowmeter accurately to control flow, enter then in the solid-state grinding aid slowly-releasing machine solid-state grinding aid is carried out slowly-releasing, obtain concentration about 100,000/to 1,000,000/liquid grinding aid, add grinding machine by shower nozzle and get final product.
The utility model is taked technique scheme, has following beneficial effect: after this liquid grinding aid enters grinding machine, fully mix with raw material, can fully clear up the static on lining board of grinder, material, steel ball, the steel section, solve bag ball, bag section to greatest extent, stick with paste the liner plate phenomenon, thereby improve mill efficiency about 10～15%; Owing to, accurately control addition according to the variation of mill feed material, can reach the flowing velocity of reasonable control material, make each storehouse material ball ratio suitable, each storehouse effect of balance, thus improve mill efficiency 5～10%.After this liquid grinding aid enters grinding machine, contact prosperous suitable quantity of water steam, take away, can reduce the gentle cement temperature of mill, reduce the gypsum dehydration chance, stabilized product quality by mill tail blower fan with high-temperature material, liner plate, steel ball, steel section etc.Because the Electrostatic Absorption phenomenon reduces, fine powder does not reassociate, and major part can in time be discharged outside the mill, makes the cement granules grating reasonable, thereby the fineness ratio surface area increases on an equal basis, and specific area improves can directly facilitate early strong the raising.
Use this control technology, can improve 10～25% when general effect is for platform at Super-fine grinder, when driving stream mill, Kombi and stepping on the cement that mill produces; Fineness 4900 hole sizers tail over 1.5%～5.0% and can accurately control; Specific area 320～450m
2/ kg can accurately control; Cement goes out to grind temperature can descend 10～20 degrees centigrade; Equal raw material ratio and control out grinding rate, specific area is mentioned 10～40m
2/ kg; Equal raw material ratio and control out grinding rate, the early strong 0.5～1.5Mpa that improves.
The specific embodiment
Below in conjunction with embodiment the present invention is described in detail:
With adding pH value in 1 kilogram the solid-state grinding aid is following clean cold water 20 kilograms of 6～8,25 degree, makes liquid grinding aid; Spray in the grinding machine by volume control device.
