LINDEMANN Shredder Plants in Operations for the Scrap Industry

Since many tears and in many countries, LINDEMANN Shredder Plants transform complete derelict motor cars, sheared car body scrap (slabs), light bales, and miscellaneous scrap, such as refrigerators, stoves, washing machines, bicycles, and light sheet metal scrap , etc. into clean, dense and small-piece shredded scrap-a valuable raw material for the steel industry. LINDEMANN manufactures complete plants of different sizes designed for output figures from 6 to 150 tonnes per hour, including effective equipment for the charging of the material to be processed as well as for the cleaning, dedusting, and transporting of the shredded products.

When processing derelict cars, one obtains, depending on their composition:

67-75% clean steel scrap

24-30% non-metallic waste

1.0-3.0% non-ferrous metals

Shredded scrap produced by LINDEMANN Shredder Plants has the following features:

y     High density

y     A specific bulk weight of 1-2.5kg/dm3

y     uniform pieces of an average size of 50-150mm

y     high quality and cleanness

The non-metallic refuse (rubber, textiles, plastics, wood, dirt, sand, etc.) has an average bulk weight of 0.5 tonnes/m3. Just like household refuse, it is suitable for controlled tipping.

The LINDEMANN Shredder System at a Glance

LINDEMANN Shredder work according to a special system, the main feature of which is the grid-plate arranged above the rotor.

For special requirements, however, a special shredder type “R” with upper grid-plate and additional basket type bottom grid can be supplied.

The scheme shows the working method of the LINDEMANN shredder, the working cycles are:

1. 1. Automatically controlled feed of charged scrap .
2. 2. Tearing-off at the anvil edge .
3. 3. Size-reducing at the baffle plate edge .
4. 4. Densifying at the baffle plate , at the grid , and by impact with other scrap pieces .
5. 5. Exit of shredded scrap pieces through the grid openings .
6. 6. Sucking-off of flying dust and waste .
7. 7. Discharge of the shredded scrap .
8. 8. Ejection of coarse unshreddable pieces .

Advantages of LINDEMANN Shredder Plants

1. 1. Low foundation cost .
2. 2. Low power consumption due to the smooth housing bottom and the milling-kind tearing effect of the hammers at the anvil edge .
3. 3. Insensitivity against coarse pieces which cannot get stuck in the smooth housing bottom and which are ejected through the hydraulically operated ejection door without interruption of the production process .
4. 4. High density of shredded scrap due to the scrap pieces rebouncing at the grid , at the baffle plate , and by impact with other scrap pieces .
5. 5. Quick exchange of grid by simply pushing out the grid plate side-ways , this is of particular importance if scrap density is to be changed by substituting grids with different grid openings .
6. 6. Long “fall” of the shredded scrap pieces from grid exit to shredder exit - which means maximum cleaning effect by means of the connected dust extraction .
7. 7. Maximum flywheel energy due to the disc-type rotor , thereby reduction of current peaks during shredding .
8. 8. Robust and wear-resistant feeding and charging equipment , scrap feed depending on the power in take of the shredder driving motor , thus , peak current and overcharging of the shredder are avoided , and a high output is achieved .
9. 9. Highly wear-resistant lining of all parts of the shredder housing subjected to strong wear with easily exchangeable wear parts .

Disc-rotor with exchangeable wear-resistant wear caps .

Here some details

Every detail counts if a shredder plant shall work trouble-free and give highest performance. We know how every detail must be designed and carried out by our experience gained in the construction of many shredder plants.

1. 1. The shredder housing is hydraulically tiltable at the rotor centre line to give easy access to the interior of the shredder.

Arrangement can also be made for the rotor to be lifted with the housing top.

2. 2. Due to the wear-resistant protection caps fitted to the rotor, build-up welding of the rotor discs is no longer necessary.
3. 3. The hydraulic device for dismantling the hammer axles facilitates the exchange of hammers and reduces maintenance
4. 4. The control desk is designed for simple and safe control of the whole plant automatic supervision of all electric drives and instruments with indication of their operation on a luminous

5. 5. Separating drum with dropping
6. 6. Magnetic separating station with following steel sorting conveyor.
7. 7. Slewable belt conveyor for the discharge of clean shredded steel scrap on to stockpile or for direct loading into

LINDEMANN Shredder plants Serve the Environmental Protection

They do away with derelict motor cars and ugly mounds of mixed scrap, they work ecologically beneficial, vibration-free, without dust.

By means of noise protection equipment, the noise level can be reduced to values officially prescribed.

8. Sound absorbing walls around a shredder plant.
9. Vibration absorbing units especially developed for LINDEMANN Shredders prevent the transmission of vibrations and keep foundations costs low.
10. Dust extraction equipment developed by LINDEMANN ensures dust-free shredding, conveying, and loading of the shredded products. The degree of purity of the exhaust air complies with all statutory provisions.

Operation instruction

A.1 Introduction

A1.2 Basic information

Materials suitable for shredding

Maximum thickness of material:

For sheet metal plates:                           2mm

For sectional steels and pipes:               5mm wall thickness

For rounds:                                             10mm

Important to note:

Please avoid by all means to only charge material having there maximum dimensions. Such material should be fed into the shredder in small quantities only, most preferably mixed with other light scrap.

Materials unsuitable for shredding

-   Wire bales and wire ropes (danger of accident-danger of shredder exit getting chocked and blocked).

-   Long flats or strip-shaped sheet-metal sections in a length ranging from approx. 3 meters onward when they are charged in larger quantities (danger of overfeed of shredder).

-   Receptacles (containers) or items containing explosive, inflammable, toxic or corrosive substances in liquid, dust-like or gaseous condition (danger of explosion, danger of accident), in particular, keep receptacles or containers from the chemical and colour producing industry away from the shredder, because:

(a) Their content - even if only small residual quantities are involved - in most cases, is highly explosive and toxic.

(b) Because cans (canisters) and receptacles are partly tinned, so that they would increase the tin content of the shredded scrap beyond the admissible limit.

Preferably, the shredder is used for:

-   Car bodies

-   Stoves, refrigerators, washing machines, steel furniture for offices and similar items.

-   Stampings and light destructor scrap (collected light iron scrap).

How to prepare the car bodies:

Car bodies are only allowed to be fed into the shredder after having been prepared in a dequate manner.

The old cars must be freed from the following items: Liquefied petroleum gas tanks

-    In view of the highly explosive gas mixture which in case of explosion would lead to damaging of the dust extractor equipments.

Tyres

-    Because of their steel liners which cause the various tyre pieces to drop on to the steel scrap conveyor-belt instead of being directed to the waste belt by means of the subsequently operating magnetic drum.

The following elements should be removed from the old cars: Motors and gears

-    In view of the high portion of alloyed material the steel mills do not like to find in the ultimate or end products.

-    Because of the increased wearing effect in the shredder.

-    In view of contamination of the oil (oil mud deposits in the pipe system). Car sets (if the shredder installation does not feature a separating drum)

-    On account of the optically seen poor appearance of the shredded scrap, with hooked-on bolster and textile waste.

Note:

Gasoline tanks either have to be removed completely or perforated in such a way that no gasoline remnants are still in them (please refer for this to it, “unsuitable materials for

the shredder”).

Liquefied petroleum gas tanks shall be removed completely because the stuff contained in them would produce a highly explosive gas mixture in the shredder, and as a consequence, the entire dust extractor equipment would be exposed to the danger of damaging (please refer for this also to “how to prepare the car bodies”).

Batteries and radiators have to be removed if not done already by the scrap car suppliers on account of their good sales price.

Car bodies can be processed both in pre-squeezed and unsqueezed condition. Axles, springs and wheels can be shredded together with the car bodies.

So called car body slabs are, in general, not suitable for being shredded because the shredder may be overstressed by them and increased current peaks may occur. In any event, the portion determined for the car body slabs to be processed should remain within a justifiable limit.

Caution:

The shredding of scrap bales is to be strictly excluded coarse items contained in the bales are neither detectable nor can they be removed. Therefore, there would be complete breakdown of the installation on account of rupture caused by coarse items.
