Abstract
A kind of dolomite powder and working method thereof that is applicable to coating, rubber, oil paint additive, feature are that said dolomite powder contains CaO3234%; MgO25～27%.The fusing point of this product is 2200～2300 ℃; Fineness is 300～325 orders; Said working method is with ore machine top charging in pulverizing, and grinds in pulverizer, and the dolomite powder after the air-flow that rotation produces by pulverizer will grind is blown out by " U " shape flour extraction pipe that falls that is contained in pulverizer top.This product advantage be the fusing point height, wear resistance, water tolerance and photostabilization are all higher, its whiteness is equivalent to titanium dioxide; The working method facility investment of this product is few, and tooling cost is low.
Description
The present invention relates to a kind of dolomite powder and working method thereof.
Making additive in the prior art in coating, rubber, paint etc., mainly is titanium dioxide and lithopone, and wherein the titanium dioxide fusing point can reach 1750 ℃, and it is wear-resisting, so all wish to adopt titanium dioxide to make additive, still, because titanium dioxide costs an arm and a leg, actual in making products such as coating, rubber or paint, generally all adopt precipitated calcium carbonate, and precipitated calcium carbonate not only fusing point is low, wear no resistance, and water tolerance is also poor, does not guarantee the capability and performance of products such as coating, rubber or paint.
The object of the present invention is to provide a kind of price low, have the fusing point height again, wear resistance, water tolerance, photostabilization height, and be suitable for doing the dolomite powder and the working method thereof of additives such as coating, rubber or paint.
Product of the present invention is directly to obtain with machining process, it is characterized in that containing CaO 32～34%; MgO 25～27%, and the fusing point of this product is 2200～2300 ℃; Its fineness is 300～325 orders.Said working method is, the ore that will contain mentioned component is through the charging of pulverizer middle and upper part, grind in pulverizer, and directly " U " shape flour extraction pipe is installed down on pulverizer top, the dolomite powder after the air-flow that produces by pulverizer rotation will grind blows out by " U " shape flour extraction pipe.
The advantage of product of the present invention is the fusing point height, because the content height of MgO, thereby wear resistance, water tolerance and photostabilization are all higher, its whiteness is equivalent to titanium dioxide.Working method less investment of the present invention does not need or not adopt screening with air blast or blower unit yet, and its fineness can highly realize by regulating " U " shape pipe, thereby tooling cost is low, and product price is low.Product of the present invention is applicable to the additive of making coating, rubber, paint, plastics, and is applicable to papermaking, regenerated fiber, and industrial circles such as welding electrode can replace raw materials such as titanium dioxide, lithopone, precipitated calcium carbonate.
Accompanying drawing is the synoptic diagram of processing unit (plant) of the present invention.
Below in conjunction with accompanying drawing working method of the present invention is elaborated again:
The ore that will contain CaO 32～34% and 25～27% drops among the pulverizer l through the J of the opening for feed place of the feed-pipe 4 of middle and upper part, pulverizer l side, motor drives belt pulley 2 also passes through 3 rotations of belt pulley 2 drive main shafts, the pulverizing hammer 5 that is welded on the main shaft 3 constantly beats ore, add that the crowded wiping on surface is ground between ore and the ore, make ore become powdery by bulk gradually, because pulverizer is closed state, after main axis rotation, form a kind of high pressure draft in the pulverizer, force fall unique of dolomite powder after the grinding to blow out body in " U " shape flour extraction pipe 6 through pulverizer l end face middle part; Said " U " shape flour extraction pipe and the body end that links that falls is connected by the more piece pipe that has ring flange and forms, and by adding, subtract the quantity of more piece pipe, the height of powder output-adjustable pipe is also regulated the fineness of dolomite powder with this.
Claims (3)
