Abstract
The present invention discloses rollers of a cement finish grinding roller press. the rollers comprises two rollers with center shaft parallel, wherein the rollers are in a frustum-shaped structure along the axial direction, two rollers mutually coordinate to squeeze and crush materials, the rollers are provided with large and small end surfaces vertical to the axial line, the large end of one roller is in the same side as the small end of the other roller, and the relative rotation speeds of the two roller are the same or different. The squeezed and crushed materials have spherical or ellipsoidal crystal shape, meeting the cement finish grinding needs, so that the roller press completely replace cement finish grinding equipment, thus reducing the power consumption of the cement finish grinding system, simplifying the process of the cement finish grinding system processes and lowering equipment maintenance cost.
Description
Technical field
The present invention relates to cement industry equipment, particularly cement final grinding system roll squeezer.
Background technology
Roll squeezer is a kind of milling equipment of fragile material, speed is identical, roll surface is smooth, roller carries out high-pressure extrusion to material and pulverizes in relative rotation by two, roll squeezer has been widely used in the cement grinding industry as a kind of energy-efficient product of maturation, has obtained obvious effects.But because the material crystal shape after the roll squeezer extruding is sheet or column, if words as the cement end milling equipment, the cement of producing exists the defective that water requirement is big, concrete strength reduces, so need and pre-grinding system of the supporting composition of grinding machine or combination grinding system usually.And grinding machine is as the cement end milling equipment, has power consumption height, problem that equipment maintenance cost is big all the time.
Summary of the invention
Goal of the invention of the present invention is: at the problem of above-mentioned existence, the whole grinding roll squeezer of a kind of cement roller is provided, thereby makes roll squeezer substitute grinding machine fully, effectively reduce the cement system grinding pow consumption as the cement end milling equipment, simplify cement final grinding system flow process, reduce equipment maintenance cost.
The technical solution used in the present invention is such:
The whole grinding roll squeezer of a kind of cement roller comprises two rollers that axis is parallel, and described roller is the taper type structure along axis direction, and two rollers cooperatively interact material is carried out attrition crushing.
Described roller has big end and two end faces of small end perpendicular to axis, and a big end of roller and another roller small end are in the same side.
Described roller outside diameter 600～2400mm, roller end diameter 400～2200mm, roll width 600～2200mm.Material crystal shape behind attrition crushing is spherical or the ellipsoid shape.
Described two counterrotating rotating speeds of roller are identical or different.
Every roller of the present invention has big end and two end faces of small end perpendicular to axis, and roller end face size and roll width are determined according to the throughput of material.The situation that the rotating speed of two rollers is identical: under the certain situation of roller angular speed, the linear velocity difference of roller each point, the material movement speed that is positioned at the roller different parts is also just different, thereby material also is subjected to shear stress when being under pressure; The situation that the rotating speed of two rollers is different: material is in the extruded process along roll surface, because roller rotating speed difference, the linear velocity of material rotation that is positioned at roll surface is also inequality; Because roller is the conical surface, material is also inequality in the linear velocity of roll surface difference, thereby material also is subjected to the shear stress between the material when being under pressure simultaneously.By roller processing of the present invention, the crystal shape of material is spherical or the ellipsoid shape from sheet or column by correction of the flank shape, finishes the whole grinding process of material.This design can effectively reduce cement water requirement, the assurance concrete strength of production.
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows:
The whole grinding roll squeezer of cement of the present invention roller can make roll squeezer substitute grinding machine fully as the cement end milling equipment, effectively reduces the cement system grinding pow consumption, simplifies cement final grinding system flow process, reduces equipment maintenance cost.
