Description
Technical field
The present invention relates to tup technical field, be specifically related to a kind of tup for hammer mill.
Background technology
The main working parts of hammer mill is the rotor with hammer.Rotor is by main shaft, disk, bearing pin
Form with hammer.Motor rotor driven high speed rotating in crusher chamber.Tup is main vulnerable part,
The quality of tup directly affects the crushing efficiency of disintegrating machine.Tup during operation, in addition to being clashed into,
Also being impacted by material, be so repeatedly used for a long, the work surface of tup will be destroyed, and makes table
Face shape changes.The most domestic hammer head of hammer crusher major part is made by potassium steel.
Material feeds in machine from top material inlet, by high-speed motion the hitting of hammer, impact, shear, grind
Act on and pulverize.In rotor bottom, it is provided with in sieve plate, comminuting matter and passes through less than the grade of screen size
Sieve plate is discharged, and continues the strike by hammer and grinding more than the coarse fraction detention of screen size on sieve plate,
Outside finally by sieve plate discharge machine.
Hammer mill is the industrial department widely used production equipment such as building materials, metallurgy, chemical fertilizer, and tup
It it is the vulnerable part that consumption is the biggest.The working surface of tup contacts with material, produces heavily stressed abrasion.
Owing to the material that is broken is usually the hard objects such as rock, metallic ore, the abrasion of part is that ratio is more serious
's.By analyzing tup surface microscopic topographic, the wear process of tup belongs to deformation and erosive wear is combined
The result of cooperation.This is running up due to tup surface, and material is carried out by the motional inertia of tup
Hit and attrition crushing.During relative motion, these materials interact with piece surface, no
Simply slide, also impact, roll, the mode such as wash away.When abrasive hardness exceedes material hardness, abrasive material
Corner angle make material generation Plastic Flow be expressed to the surrounding of pit by thrusting material surface, material deform
To a certain extent, abrasive grain is crushed.Multiple granules contact with cheating material deformed around, are allowed to again become
, there is Plastic Flow in shape, work-hardening capacity increases further.When the strain fatigue limit exceeding material
Time formed grinding come off.
In Chinese Patent Application No.: disclose a kind of tup for hammer mill in 200910001666,
It is assembled with hammer handle by hammer body.Described hammer body is billiard table shape, and billiard table centrage is provided with round open-work,
Billiard table lower end circle open-work matches with hammer handle upper hollow shaft cylindrical, and straight pin is through hammer body circle open-work, with hollow
Bar endoporus matches, and is fixed by bolt, channel nut and split pin, forms assembled billiard table shape hammehead structure.
This technical scheme is in actually used engineering, and straight pin, bolt, split pin are highly prone to damage, this skill
Art scheme haves much room for improvement.
