Description

The general-purpose cement ball mill assembly method that a kind of grinding efficiency is high, power consumption is low
Technical field
The present invention relates to general-purpose cement ball mill technical field, specifically a kind of grinding efficiency be high, general-purpose cement ball mill assembly method that power consumption is low.
Background technology
The ball mill that general-purpose cement grinding uses, its cylinder inboard wall is fixed with liner plate and is not worn to protect cylindrical shell.Have dividing plate to be one to several bin by grinding machine horizontal partition in cylindrical shell, the abrasive body of some is equipped with in each bin inside.Abrasive body is generally the fineness requirement etc. according to the grindability being polished material, granular size, finished product, by mill ball or the grinding post of different size dimension, specification shape, carries out matched combined by a certain percentage.This matched combined industry is referred to as the grating of abrasive body, as: the grading distribution scheme in certain grinding machine storehouse is: the total useful load in this storehouse is 100 tons, wherein 10 tons, the ball of Φ 50mm; 30 tons, the ball of Φ 40mm; 30 tons, the ball of Φ 30mm; 20 tons, the post of Φ 20 × 25mm; 10 tons, the post of Φ 16 × 22mm.The rotation of grinding mill barrel drives in mill by the abrasive body motion that certain grading distribution scheme matches, at abrasive body and liner plate, produce between abrasive body and abrasive body and impact, rub, thus to material acting, make material become the powder of required fineness from bulky grain, and as: raw meal powder, cement, breeze etc.At present, the liner plate of general-purpose cement grinding machine and abrasive body use ferrous alloys material always.Engineers and technicians do a lot of work in the shape etc. of the composition of ferrous alloys material, production technology and abrasive body, but are never applied on general-purpose cement ball mill containing corundum ceramic material liner plate, abrasive body.Because the ratio of ferrous alloys is great, make the load of grinding machine huge; In addition, the crystalline structure feature of ferrous alloys also determines the liner plate of alloy material, the grinding efficiency of abrasive body to cement component material is low; Meanwhile, to make because of the identical of kinematic parameter between the ferrous alloys abrasive body with density to do work between neighboring abrasive body very little.Therefore, the Energy Efficiency Ratio of general-purpose cement ball mill is quite low, and energy consumption of unit product is quite high, makes the sector become energy consumption rich and influential family in all industries of national economy.
Summary of the invention
The object of the present invention is to provide the general-purpose cement ball mill assembly method that a kind of grinding efficiency is high, power consumption is low, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
The general-purpose cement ball mill assembly method that grinding efficiency is high, power consumption is low, general-purpose cement ball mill uses the abrasive body containing corundum ceramic material.
Particularly, the abrasive body in any storehouse of grinding machine comprises following three kinds of assembling ratios:
(1), by abrasive body material in any storehouse of grinding machine distinguish, the ratio of the volume of the total abrasive body in the abrasive body of unlike material this storehouse shared is: the volume ratio that ferrous alloys matter abrasive body accounts for the total abrasive body in this storehouse is 0%-50%, the volume ratio accounting for the total abrasive body in this storehouse containing corundum ceramic material abrasive body is 50%-100%.
(2), in any storehouse of grinding machine abrasive body is the abrasive body containing corundum ceramic material, but two kinds of density difference 0.5g/cm 3above, distinguish by the volume containing the total abrasive body in this storehouse shared by corundum ceramic material abrasive body of different densities, wherein a kind of volume ratio accounting for the total abrasive body in this storehouse is 0%-50%, and another kind is 50%-100%.
(3), by abrasive body material in any storehouse of grinding machine distinguish, the volume ratio of the total abrasive body in the abrasive body of unlike material this storehouse shared is the volume ratio that ferrous alloys matter abrasive body accounts for the total abrasive body in this storehouse is 0%-40%; Two kinds of density difference 0.5g/cm 3the ratio that above corundum ceramic material abrasive body accounts for the total abrasive body volume in this storehouse is 60%-100%; And wherein a kind of corundum ceramic material abrasive body accounts for the ratio of the total abrasive body volume in this storehouse is 20%-80%, another kind accounts for the 20%-80% of this storehouse abrasive body cumulative volume;
And when general-purpose cement ball mill is only containing a storehouse, this storehouse use in above-mentioned three kinds of assembling ratios any one; When more than general-purpose cement ball mill is Liang Cang and two storehouses, at least in the end any one that storehouse uses in above-mentioned three kinds of assembling ratios is ground in a storehouse namely.
After any storehouse of general-purpose cement ball mill uses any one in above-mentioned three kinds of assembling ratios, total filling rate of this storehouse abrasive body is 33%-50%.
Any storehouse of general-purpose cement ball mill uses the liner plate containing corundum ceramic material.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is directed to current the used ferrous alloys liner plate of general-purpose cement ball mill, the defect that load is large, grinding efficiency is low, grinding machine Energy Efficiency Ratio is low, energy consumption of unit product is high that abrasive body occurs, use the liner plate containing the hard wear-resistant ceramic material of the high-strength height of corundum, abrasive body improve traditional general-purpose cement ball mill.About the density containing corundum ceramic material is the half of ferrous alloys, reduce mill load; In addition, have unique crystalline structure containing corundum ceramic material, its grainding capacity is again the several times even tens times of ferrous alloys; Meanwhile, the differentiation of abrasive body kinematic parameter in grinding machine of different densities, the grinding between the abrasive body that the grinding between the abrasive body of different densities is done work than equal densities is done work large many; Moreover, because the quality containing corundum ceramic material abrasive body and liner plate alleviates greatly, significantly can improve the abrasive body filling rate in any storehouse of grinding machine, even can bring up to 33%-50%.So the load of the general-purpose cement ball mill after improvement reduces greatly, Energy Efficiency Ratio improves greatly, the energy consumption of unit product can reduce by 15%-50%.
