Abstract
The utility model provides an increment device of a vertical mill, which belongs to the technical field of crushing and processing hard and brittle materials in a metal mine or a nonmetallic mine, andsolves the problems that the small material storage quantity of grinding discs of the prior mills affects the production efficiency of the mills. The increment device is arranged on the edge of a round grinding disc of the vertical mill and comprises an annular material blocking ring which helps to increase the material storage depth of the grinding disc in the vertical direction, and the material blocking ring is fixedly connected with the grinding disc in the circumferential direction. In the device, since the annular material blocking ring is added on the grinding disc of the vertical mill, the material storage depth of the grinding disc is increased, the defect of undersize material storage space of the grinding disc of the vertical mill is solved, and the vertical mill can store moreraw materials. Moreover, the work efficiency of the vertical mill is also improved.
Description
Technical field
The utility model belongs to hard crisp material grinding processing technique field such as metallic ore and nonmetallic ore, relates to a kind of increment device of increment device, particularly a kind of vertical grinder of improved grinding equipment.
Background technology
The domestic grinding machine that is used for industries such as mine, metallurgy, chemical industry, electric power, building materials generally adopts vertical grinder at present.The primary structure of vertical grinder partly is made up of separator, Burnisher apparatus, pressue device, reductor, motor, housing etc.Grinding roller is the critical piece that material is rolled grinding.It is installed on the curved boom of grinding machine, under the effect of external force, is pressed on the material of mill, and under the drive of mill, grinding roller rotates thereupon, thereby material is rolled and pulverizes.Mill is fixed on the output shaft of reductor, and the rotating speed of mill is exactly the rotating speed of speed reducer output shaft, and mill top is the material bed, on the material bed cannelure is arranged, and material is pulverized by grinding roller in cannelure.
Its operation principle is as follows: material drops on mill central authorities from feed opening, because centrifugal action, material moves from mill mediad mill edge, during through the cannelure on the mill, be subjected to rolling of grinding roller and pulverize, pulverized material continues to move to the mill edge, up to being taken away by the air-flow at vane place.And large granular materials drops to continuation pulverizing on the mill.Material in the air-flow is during through the separator on top, and under the effect of guide vane, coarse fodder is fallen on the mill from the awl bucket, and fine powder goes out mill simultaneously with air-flow, is collected by the dust arrester of system, and the powder that is collected is the product that Vertical Mill grinds.
In the process of grinding roller, because the volume of cannelure is too small, can not store more material, the material that grinding roller rolls is less, and this has seriously limited the operating efficiency of grinding machine.
Summary of the invention
The purpose of this utility model is too small at existing vertical grinder mill volume, and the shortcoming of storing insufficient space has proposed a kind of mill volume that is used to increase, and makes grinding machine roll the increment device that output improves.
The purpose of this utility model can realize by following technical proposal: a kind of increment device of vertical grinder, be arranged at the circular millstone edge of vertical grinder, it is characterized in that, this increment device comprises the annular collet that increases the mill storing degree of depth on the vertical direction, and described collet and mill circumferentially are connected.
After the mill periphery had been installed this collet, the degree of depth on the mill vertical direction increased, and can increase for the material thickness that grinding roller rolls, and grinding roller rolls the efficient that produces powder and improves.
In the increment device of above-mentioned vertical grinder, described collet is an annular, and concentric with mill.
In the increment device of above-mentioned vertical grinder, described mill is a flour milling with the machined surface that the mill rod rolls, and the flour milling of above-mentioned mill is taper.Constitute the clearance-type material milling surfaces between mill rod and the mill.
Compared with prior art, this device has been by having increased an annular collet on the mill of vertical grinder, thereby increased the storing degree of depth of mill, improved the too small defective in vertical grinder mill storing space, makes vertical grinder can store more raw material.Improved the operating efficiency of vertical grinder.
Description of drawings
Fig. 1 is that this increment device is applied to the structural representation in the vertical grinder device.
Among the figure, 1, mill; 2, grinding roller; 3, annular groove; 4, collet; 5, grinding chamber; 6, frame; 7, blower fan.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, mill 1 is arranged in grinding chamber 5 bottoms of vertical grinder, the edge of mill 1 is provided with the collet 4 of an annular, center, mill 1 below connects rotating shaft, arrange on mill 1 card that one is the annular groove 3 at center with mill 1 axle center, the rear end of grinding roller 2 is connected on the frame 6, and the front end cooperation is stuck in the annular groove 3, and material drops on the mill 1 from feed opening.
During work, rotating shaft drives mill 1 and rotates, because centrifugal action, material moves from mill 1 mediad mill 1 edge, when arriving the annular groove 3 on the mill 1, be subjected to rolling of grinding roller 2 and pulverize, pulverized material is picked up by the blower fan 7 at grinding chamber 5 tops, the less powder of particle is sucked out grinding chamber 5 and collects, and the powder that is collected is the product that grinds.And large granular materials continues to pulverize from newly dropping to mill 1.
After collet 4 had been installed, the storage depth of mill 1 in the vertical direction increased, and can store more material, and the production efficiency of grinding roller 2 when grinding improves.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Claims (3)
