Abstract

Vertical shaft impact crushers (VSI), mainly used in aggregate production, are operated in mining

industry widespread in the world. The VSI, which is used as a tertiary or quaternary cursher, is

very well known in aggregate industry by its production of cubical particles and in mining industry

by its fines generation. The particles fed into the crusher is accelerated by means of the rotor

and directed to the walls of the crusher where a high velocity impact breakage occurs. The

adjustable rotor speed allows to crush the material from different energy levels to obtain different

product finenesses. In this study the size reduction performance of the crusher was assessed

with respect to rotor tip speed rather than particle shape. Results showed that the product gets

finer as the rotor tip speed increases and the optimum operating condition can be achieved by

adjusting the capacity of the crusher.

Abstract

Dik milli darbeli kırıcılar (VSI), agrega üretimi başta olmak üzere, dünya genelinde madencilikte
geniş bir uygulama alanına sahiptir. Üçüncül ve dördüncül kırma aşamalarında kendine yer bulan
dik milli darbeli kırıcı, nispeten kübik şekilli ürün vermesiyle agrega üretiminde, ince üretimi
sebebiyle de madencilikte ön plana çıkmaktadır. Dik milli kırıcıda taneler yüksek hızda dönen
rotor vasıtasıyla kırıcı duvarlarına doğru fırlatılmakta ve darbe altında kırılmaktadır. Ayarlanabilen
rotor hızı sayesinde farklı enerji seviyelerinde kırma işlemi gerçekleştirilerek farklı inceliklerde
ürün elde edilebilmektedir. Bu çalışma kapsamında farklı rotor hızlarındaki kırıcı performansı
boyut küçültme ve enerji tüketimi açısından değerlendirilmiş olup ürün tane şekli yönünden
herhangi bir değerlendirmede bulunulmamıştır. Sonuçlar artan rotor hızına bağlı olarak ürünün
inceldiğini, kapasitenin de optimize edilerek enerji tüketimi açısından daha verimli bir operasyonel
koşulun sağlanabileceğini göstermiştir.
