DE2350981A1 - Foundry moulding sand prepn. appts. - has sieves, crusher plates, and crusher discs, in vibratory forwarding trough - Google Patents

Abstract

Appts. for prepg. granular material having conglomerates, esp. foundry moulding sand, includes crusher jaws and plates in the path of the material; the plates are fitted in a frame with a vibratory drive, and mutually parallel annular discs are located above them as jaws, with a shaft pressing through them, which shaft is smaller than their middle holes so that the inoperative discs abut the plates with their peripheries. The frame is a vibratory forwarding trough which is closed at the sides and below has 2 forwarding planes, the first, upper of which is formed by alternately arranged sieves and crusher plates, followed by an outlet for non-comminutable material, and the second of which comprises the floor of the frame, followed by an outlet for the prepd. material, and with a suction connection above it for conection to a suction fan. Through comminution and dust removal are performed even with large flows of material including hard, e.g. metallic, non-comminutable material.

The material to be processed is the frame 3 on the Feed nozzle 18 supplied and initially falls on the Catch plate 8. The further transport leads from the inclined catch plate over the first of the sieves 7 to first crushing plate 8. Sufficiently fine material can already pass the front sieve 7 and falls to the floor 4 of the frame 3 The guide blades 9 are designed so that that the accruing material can pass them; the air flow hitting the falling material across it This tears all too fine particles, such as dust particles, binder residues or the like., With sicn, so that they through the The suction nozzle is pulled off and separated out in a separator provided between this and the following suction fan will.

The material that is too coarse to pass through the sieve reaches the first dex breaker plate !! 8 and gets into the gap which is formed between the "circumference of the cutting discs 23 and the crushing plate. The mutual movement between these leads to the fact that pumps contained in the material are hit against the cutting discs in accordance with the vibration. This begins from the '' The length of the roughly wedge-shaped gap formed between the circumference of the blades and the breaking plate corresponds to that of the lump tend to shatter, but the smooth forces are also exerted on the circumference of the disks; the radial component of these forces lifts the disks, while the circumferential component causes the disks to rotate counterclockwise so that the disks tend to lift them To unscrew the impacting Aluwpen out of the gap or to inhibit their forward travel and, in addition, d urcii grinding una kahl processes contribute to their crushing.

Essentially larger or smaller ikatenalklimipen the first set of disks, and when the disks act, the aterial clusters are supported over a large area only to a small extent by finer-grained material, since this has essentially already fallen on the floor 4. The clumps of material between the discs 23 and the crushing plate B are therefore strongly de-emphasized, without being supported by finer ateral support, and the remaining aluminum strips are long in the air by the twisting of the discs which counteracts the urgency "Effective range of the same are met, so that the comminution capacity is very high.

The first crushing plate is followed by a second sieve 7 arranged with a reduced incline. With the lower inclination, longer dwell times on the sieve and, in the long run, increased lead times are achieved with only a short execution of the sieve.
