Description
Technical field
The present invention relates to a kind of old metal utilization technology field, more particularly to a kind of efficient iron filings shearing-crushing
Machine.
Background technology
It is that waste metal product etc. is carried out into broken processing that old metal, which is recycled, makes the important step of steelmaking feed
Suddenly.At present, domestic and international iron and steel enterprise generally carries out old metal utilization using broken metallic briquette technique, to improve old metal volume
Proportion, prevents from exploding when delivering electric furnace, dissolution rate is lifted under certain condition, meet the requirement of " yellow phosphate ".
In China's old metal is reclaimed, very big proportion is occupied as the intermetallic composite coating iron filings of electric furnace steel making quality raw materials, it is raw
Enterprise is produced by the way that machining iron filings are carried out with broken rear briquetting, the bulk specific gravity of iron filings block is reached rational scope.Exist at present
The crushing technology field of iron filings, the main crushing technology using two kinds of structure types：One kind is paddle type mill crushing technology, its work
Principle is the general principle of the tup impact using rotation at a high speed, under the driving of high speed high torque motor, utilizes distribution and main shaft
On multiple tups kinetic energy, in turn impact enter crusher chamber in waste iron filing, by the gap between body liner plate and tup,
Iron filings are impacted, satisfactory iron filings fragment is rolled into.Mainly made using the disintegrating machine of this principle by hammer mode
Waste iron filing is crushed, energy expenditure, and tup stress is big, and waste iron filing needs iterative cycles to impact, it is necessary to which the long period can be only achieved
It is broken to require, therefore its energy consumption is big, efficiency is low, and equipment attrition is serious.For paddle type mill crushing technology feature, Chinese patent
CN206069963U discloses a kind of metal disintegrating machine, and its corrective measure is that the tup plane of disruption is zigzag face, is improved broken
Effect.
What another broken iron filings were commonly used is to use toothed roller type crushing technology, has two kinds of structures of single-tooth roller and double teeth roller, makes
With more mainly double teeth roller crushing technology.Chinese patent CN 204307691U disclose a kind of high-efficiency environment friendly old metal and broken
Broken machine, its operation principle of the technology is that cracking hammer head and crushing cutter are arranged at intervals on the crushing toothed roller of double-geared roller crusher, right
Old metal, which adds to tear, cuts fragmentation, and broken engine efficiency is improved to a certain degree.
All there is larger defect in the disintegrating machine of above two mode：1st, crushing efficiency is low, it is impossible to meet enterprise to disintegrating machine
The demand that production efficiency is increasingly improved；2nd, crushing effect is poor, under the influence of step briquetting technique carry out, extrude old metal iron block proportion
It is low, it is impossible to meet electric furnace steel making principle demand；3rd, high energy consumption, noise is big, influences operating environment.
