Abstract
The utility model belongs to the technical fields of vibration mills and ore crushing, in particular to an outlet grid plate of a vibration mill. Five groups of cambered through holes are uniformly formed in a circular plate around the center of the circular plate; arc lengths of each group of the cambered through holes are sequentially increased from inside to outside; and the distances between adjacent cambered through holes in each group of the cambered through hole are identical. Both ends of each group of the cambered through holes are arranged on two intersection straight lines, wherein the intersection point of the two intersection straight lines is coincident with the center of the circular plate; and the included angle between the two intersection straight lines is 60-66 degrees. Cambered inner surfaces of the cambered through holes are the combined surfaces of vertical cambered surfaces and inclined cambered surfaces. By the special design of the cambered through holes, blocking is effectively prevented, pass rate of materials is improved, output of the mill is increased, over crushing is reduced, and the manufacture cost of the outlet grid plate is greatly reduced compared with the manufacture cost of a drilling type grid plate.
Description
Technical field
The utility model belongs to the technical field of vibrating mill, mineral aggregate pulverizing, especially relates to a kind of outlet comb plate of vibrating mill.
Background technology
Vibrating mill is as utilizing method for oscillating to come the equipment of grinding material, and big with its ratio of reduction, product granularity is concentrated; Characteristics such as output is high, and power is low are widely used; Its grinding material is grinding time and the final grade of product in grinding machine, the control of the outlet comb plate of the abrasive material that mainly is pollinated, and outlet comb plate is article and abrasive media demarcation strip, sieve plate; Also be the control panel of product grade, so outlet comb plate form directly influences grinding machine output and Granularity Distribution.Traditional outlet comb plate principal mode has: circular hole comb plate, rectangle cylindrical void comb plate and grid hole comb plate; But the final grade that this several kinds of forms are controlled is not very desirable, because grinding machine medium (rod iron) impacts, causes bore deformation, obstruction in using such as circular hole comb plate; Material is crossed pulverizing; Not only influence load, and bigger to the influence of discharging Granularity Distribution, and product quality is defective; And rectangle cylindrical void comb plate, though because perforate is big, load is fast, granularity control is not good, strip perforate simultaneously, and it is many to cross the limited production article in the product, and article off quality are many.
Summary of the invention
The utility model provides a kind of outlet comb plate of vibrating mill, has both guaranteed the final grade of grinding material product, also guarantees grinding machine output and Granularity Distribution, improves the qualification rate of ground prod.
The purpose of the utility model realizes through following technical proposals:
The outlet comb plate of the vibrating mill of the utility model; It is characterized in that on a circular slab, evenly being provided with five groups of arc-shaped through-holes around the center; And the arc length of every group of arc-shaped through-hole increases from inside to outside successively, and the spacing in said every group of arc-shaped through-hole between all adjacent arc-shaped through-holes all equates.
The two ends of described every group of arc-shaped through-hole all are located on two intersecting straight lines that the center of intersection point and said circular slab coincides, and the angle of these two intersecting straight lines is 60 °-66 °.
The arc-shaped inner surface of described arc-shaped through-hole is the aggregate surface of vertical cambered surface and inclination cambered surface.
The advantage of the utility model:
1) the utility model is compared with circular hole comb plate, and percent opening improves 50%, improves mill output, has reduced the pulverizing situation of crossing simultaneously, and has made and significantly reduce than drilling hole type comb plate cost;
2) the utility model is compared with rectangle cylindrical void comb plate, has increased structural strength, improves service life, in the control of product grade, prevents the ultra granularity product of strip;
3) particular design of the utility model arc-shaped through-hole effectively prevents to stop up, and improves the material percent of pass.

The specific embodiment
The outlet comb plate of the vibrating mill of the utility model; It is characterized in that on a circular slab 1, evenly being provided with five groups of arc-shaped through-holes 2 around the center; And the arc length of every group of arc-shaped through-hole 2 increases from inside to outside successively; The centre of gyration of each group arc-shaped through-hole 2 is the round center of circular slab 1, and the spacing H in said every group of arc-shaped through-hole between all adjacent arc-shaped through-holes all equates.Finally on circular slab 1, form five fan-shaped combination bore general layouts.In the control of product grade, prevent that the ultra granularity product of strip from passing through.
The two ends of described every group of arc-shaped through-hole 2 all are located on two intersecting straight lines 3 that the center of intersection point and said circular slab coincides, and the angle of these two intersecting straight lines 3 is 60 °-66 °.Both guarantee percent opening, increased structural strength simultaneously, improved service life.
The arc-shaped inner surface of described arc-shaped through-hole is the aggregate surface of vertical cambered surface 4 and inclination cambered surface 5.Effectively prevent to stop up, improve the material percent of pass.
Claims (3)
