Description
Technical field
The utility model relates to a kind of screening drawing mechanism of ball mill.
Background technology
The tradition ball mill mainly comprises cylindrical shell, screening drawing mechanism, feed end and burden-guiding cone etc., and wherein, cylindrical shell is the long cylinder of level, and abrasive body (being generally the steel section, to call the steel section in the following text) is housed in the cylindrical shell.Material to be ground is packed into by the grinding machine feed end in the cylindrical shell, when ball mill barrel rotates, steel section in the cylindrical shell is because frictional force and action of centrifugal force, be adjacent to shell liner by the cylindrical shell driven rotary, when being driven certain altitude, left owing to the gravity effect of itself, the steel section that falls is smashed the material in the cylindrical shell as the projectile, material and the steel section that be crashed to pieces this moment mix (to call mixtures of materials in the following text), are discharged to outside the ball mill barrel by burden-guiding cone after the screening of screening drawing mechanism.
Above-mentioned screening drawing mechanism mainly is meant the discharging grate plate that has discharging castor seam.In order to improve the trafficability characteristic of material, generally design the discharging grate plate very thin, cause the service life of discharging grate plate short partially; In order to prevent that discharging castor seam wearing and tearing back from becoming big, so discharging castor seam is designed to the vertical masonry joint structure, this vertical masonry joint structure is easy to make material to be blocked in the seam, thereby reduces the trafficability characteristic of material; In order to prevent that the steel section in the mixed material is discharged to outside the ball mill barrel by discharging castor seam, design discharging castor seam less simultaneously, this design causes the difficulty of casting to strengthen in the process of processing, and the qualification rate of finished product is low.
The utility model content
The purpose of this utility model provides a kind of screening drawing mechanism, and this screening drawing mechanism can improve the trafficability characteristic of material, reduces the excessive of steel section, the service life that can also improve the discharging grate plate simultaneously.
The purpose of this utility model is achieved through the following technical solutions: a kind of screening drawing mechanism, and this screening drawing mechanism is arranged on the discharge end of the cylindrical shell of ball mill; Described screening drawing mechanism comprises the discharging grate plate that is fixed in the described cylindrical shell and has discharging castor seam, and described screening drawing mechanism also comprises fixedlys connected with described discharging grate plate and have the discharging sieve plate of sieve aperture, fixedly connected with described discharging sieve plate and be fixed on a discharging grate plate frame on the described cylindrical shell; Described discharging grate plate frame is separated into described cylindrical shell feeding warehouse and unloads feed bin; Be provided with material section separation bin between described discharging grate plate and the described discharging sieve plate; Described material section separation bin is communicated with by feedback outlet with described feeding warehouse.
Described discharging castor seam is horn shape, and feed end is less than discharge end, thus material one that can be by feed end surely by discharge end, so material can not stop up in the process of charging, trafficability characteristic is good.
In order further to improve the trafficability characteristic of material, described discharging castor seam can be concentric circles and be distributed on the described discharging grate plate; Also can be aplysia punctata is distributed on the described discharging grate plate.
Described material section separation bin and described unloading are provided with the aplysia punctata lifting blade in the feed bin, this lifting blade can be the radially side plate of described discharging grate plate frame.
Be provided with distance block between described discharging grate plate and the discharging sieve plate, thus the distance between discharging grate plate and the discharging sieve plate can fix, thereby a further fixing material section separation bin.
Described distance block can be circle ring column, and its thickness is arranged to 45～50mm for best.
Sieve aperture on the described discharging sieve plate can be long strip sieve pores, and its width is arranged to 2～3mm for best, therefore can reduce the excessive of steel section.
In order to improve the intensity of described discharging grate plate, prolong its service life, described discharging grate plate is a stainless steel products, its thickness can be set to 3～5mm.
Described distance block is fixedlyed connected by bolt and nut with described discharging grate plate, described discharging sieve plate; The both ends of the surface of described distance block are fitted with the medial surface of described discharging grate plate and described discharging sieve plate respectively.
The beneficial effects of the utility model are:
(1) seam of the discharging castor on the utility model discharging grate plate is set to horn shape, and therefore feed end, can pass through discharge end by the material one of feed end surely less than discharge end, therefore material can not be blocked in discharging castor seam place in the process of charging, thereby has improved the trafficability characteristic of material; And the easily processing casting of the discharging castor of this horn shape seam, the product qualified rate height.
(2) the thickness discharging grate plate more in the past owing to discharging grate plate of the present utility model increases to some extent, and adopts stainless steel products, therefore not only can improve the stiffness of discharging grate plate, can also prolong the service life of discharging grate plate.
Therefore (3), be blended in the material and can't be discharged to outside the cylindrical shell of ball mill by this sieve aperture, thereby reduced the excessive of steel section greater than the steel section of this size because the utility model is designed to long strip sieve pores with the sieve aperture on the discharging sieve plate, and its width is 2～3mm.
(4) because the utility model has additional material section separation bin between discharging grate plate and discharging sieve plate, thereby the seam of the discharging castor by the discharging grate plate enters into the mixtures of materials of this material section separation bin can fully be separated, promptly the fine granular materials in this mixtures of materials is discharged to outside the ball mill barrel by the sieve aperture of discharging sieve plate, and coarse granule material and do not kept off back and turn back in the ball mill barrel by feedback outlet by the discharging sieve plate in the lump by the steel section of sieve aperture.
