Description
Technical field
The utility model belongs to sand shaker technical field, and in particular to a kind of environment-friendly type sand shaker.
Background technique
It is widely used at present in sandstone building materials, broken wait in ore dressing end largely uses PC class hammer crushing sand shaker, existing
Hammer mill has following 3 big disadvantages.
1, tup abrasion are big: no matter how science and technology improves, and using the tup of which kind of material, tup abrasion is inevitable.It is right
The research of tup state of wear and broken operating condition it is found that the reason of when tup operation, generates abrasion there are several types of: a, tup are high
Fast turn and material generate contact wear when strike collision, are the best forms for obtaining crushing effect, and tup hardness is much higher than
Material, time of contact is short, and relative displacement is small, and abrasion are small, occurs mainly in the front in tup turn direction.B, tup high speed turn
It generates hanging wipe with splashing material in crusher chamber to draw, since material has yielding space, time of contact is short, wipes and draws displacement less, breaks
Broken effect is poor, and abrasion are also little, occurs mainly in tup end face and two sides.C, fixed to rub by force: when material is still in sieve
It is held and can not be made a concession certainly by sieve on face, the tup end face high-speed friction passed through with rotating, since tup hardy hole and between centers have about
The gap of 4mm, therefore friction pressure is equal to tup weight and adds centrifugal force, one quiet one is dynamic, and high pressure end face whole process, which is wiped, draws contact, to hammer
End surface abrasion are violent.This is also the main reason for tup abrasion are accelerated in actual production.
2, broken production efficiency is low: tradition hammer is broken as tup abrasion shortens, and crushing force (yield) meeting straight line decline, one is secondary
Conventional potassium steel tup processing mountain husky 10 days or so the service life, from newly in the period of abrasion, production efficiency from high to low, with hammer
Head wears away shortening, and compass screen surface deposition expects more and more, abrasion acceleration, saturating to sieve ability worse and worse, the resistance of tup friction material web
Buddhist nun is increasing, and revolving speed is slack-off, and power consumption increases, and output decline finally replaces tup because of bored vehicle or bear and can't stand that yield is too low due to
It is to improve list that (tup often just wears one third at this time), which improves tup front strike probability to reach effective be crushed of low abrasion,
The basic method of machine itself yield.
3, fugitive dust is big: all hammer into shape breaks the tup of its rotor Zhou Junbu, when high speed rotation as electric fan, material and wind from
Feed inlet sucking, after rotor accelerates, is discharged together with powder through sieve pore, generates a large amount of fugitive dusts, pollutes environment.This is tradition
The common fault of type.
