Swarf Crusher type KBMetal chip crusher

Nederman KB 10-49 vertical metal chip crushers crush and breakbushy swarf in the swarf hopper. The crushers can accept largequantities and then reduce the swarf to an even flow of chips. Thismakes the crushers ideal for installation in a swarf handling system.The crusher is used in industries where the amount of swarf is anissue and before long swarf should be extracted, centrifuged orbriquetted. An integrated bar end rejecter ensures high functionalityand efficiency of the system.

The crusher is intended for carbon steel, stainless steel and otheralloyed steel with tensile strength up to 1.200 N/mm2 (174,000 psi),aluminium alloys, sponge iron and titanium.

Technical description of vertical chip crusherThe Nederman vertical metal chip crusher type KB accepts, crushesand breaks up bushy swarf, turnings and metal chips and at a lowrotating speed the bushy swarf is cut down to small chips at acontinuous rate. The metal crusher can accept large quantities andthen reduce the swarf to an even flow of chips. This makes themakes crusher ideal for installation in a chip processing system.

The crusher is used in industries where the amount of swarf is anissue and before long swarf should be centrifuged or briquetted. Thecrusher is intended for the following types of turnings:

•carbon steel•stainless steel•other alloyed steel with tensile strength up to 1.200 N/mm2(174,000 psi)•aluminium alloys•sponge iron•titanium

Very low operating costsThe main principle of the Nederman crushers is to allow the swarf tobe ground against each other - without hammering or cutting.This principle means very small demand for energy and very littlewear, e.g. KB49 gives 8 tons/hr at 45 kW.

Versatile loadingThe crushers accept most types of material irrespective of shape.They can be charged intermittently by a grab, hoist, fork lift orcontinuously by a conveyor.

High reliability

Unlike the hammer style crushers or shredders the Nedermancrushers are not sensitive to large bundles of swarf or swarf balls.Even large swarf balls are handled with the small power of 7.5kW(KB10).

Low noise levelThe crusher operates normally at 82dB(A). This means that they are

Function:

The swarf is fed into a conical hopper at the upper part ofthe crusher. In the centre of the hopper a shaft with a topmountredfeeder arm is rotating against angled cutters onthe sides of the hopper. The arm and cutters jointly feed theswarf towards the bottom of the hopper, where a crusher headrotates inside a stationary crusher ring. The swarf is grounddown and broken up into short chips by the crusher headand crusher ring. After completed crushing the chips aredischarged through a chute in the frame.To prevent solid parts as shaft ends, bolts etc. from gettingjammed in the crusher, it is equipped with divisible tools. Ifthe crusher head is blocked by a solid part, the crusher stopsautomatically and reverses. A segment in the crusher ringopens and the part can pass through the opening. The crusherthen automatically resumes operation.
