Background technology
Sand casting is the major processes of Foundry Production, and the casting produced by sand casting process accounts for casting total output
More than 80%.Sand is the aggregate of formation casting mold and fuse in sand casting, is important sand casting raw material.Quartz
Sand is cheap, aboundresources, is conventional sand casting sand, accounts for more than the 90% of foundry sand amount, but quartz sand
Thermal expansivity is big, and chemical heat endurance is poor, and casting is also easy to produce the defects such as rough surface, scab, vein, tangerine peel, thus while casting
It is the most frequently used foundry sand to make quartz sand in production, but quartz sand is not preferable sand casting Modeling Material.Zircon sand is resistance to
Fiery degree is high, particle shape is good, thermal conductivity is good, thermal expansivity is small, chemical stability good, and Production Practice of Casting Technologies is better than quartz sand, but it compares
Great, price is high, and with certain radioactivity, the body of people is harmful to.Olivine sand, chromite sand thermal expansivity are small, have compared with
The ability of strong anti-metal oxide erosion, but particle shape is bad, it is broken, and olivine sand cannot be used for acid solidification binding agent work
Skill.In this context, haydite casting model powder causes the extensive concern of founder author.

Further, it is that a diameter is more than mill and less than machine built with ring, the shock ring is hit in body fuselage
The annulus of body case diameter, the shock ring is arranged on same level height with mill, and the lower section connection for hitting ring is gathered materials
Bucket, the aggregate bin is infundibulate.
Further, multiple shock rings, aggregate bin and mill be set in body fuselage, the lower mouth of the aggregate bin with it is following
Hit the level suitable for reading correspondence of ring.
Further, the mill is the shaggy disc suppressed by abrasion resistant particles, adhesive etc..
Further, it is described to hit the c-type that ring section points to circle ring center in opening.
Further, a kind of abrasive disk type sand grains trimmer also includes suction opeing, and the suction opeing is arranged on body fuselage
Upper end.
Further, the motor is rotated by belt or gear, chain drive power transmission shaft.
The beneficial effects of the utility model：
Designed by the shaggy mill suppressed by abrasion resistant particles, adhesive etc., the sand entered from charging aperture
Grain falls in coarse disc surface, in the presence of mill rotary motion, and sand grains was both radially transported along mill under the action of the centrifugal force
It is dynamic, and moved in a circle under frictional force effect, sand grains is done circumferencial direction and the compound motion of radial direction；In the process, lead to
Cross between sand grains and sand grains, produce ablation between sand grains and mill, burr, projection of sand grain surface etc. it is ground fall, sand
The particle shape of son is improved.
The sand grains accelerated in the utility model through mill is thrown on shock ring under the action of the centrifugal force, and hits heap on ring
Long-pending sand, which is produced, to be hit and rubs, and the particle shape of sand has obtained further improvement, after being ground and hitting friction shaping through mill
Sand fall into aggregate bin, be ground into next stage mill and hit friction shaping, the quantity of aggregate bin and mill can basis
Requirement to sand grains shaping intensity and set, until reaching the requirement to sand particle shape.The rotating speed of mill is adjustable, mill quantity and
The good coupling of speed of grinding plate can meet artificial porcelain granule sand and other foundry sand integer requirements of one's work.
The utility model shock ring end face is C-shaped, in the course of the work, always has part sand to be deposited in shock ring, quilt
The sand in sand and shock ring that mill is dished out at a high speed is hit and rubbed, so as to reduce mill of the sand grains to shock ring
Damage, considerably reduce due to changing the loss hit ring and brought.
