The Alquezar classification grizzles are machines used for the primary classification of minerals, classifying large-sized rock.
The Grizzly body is suspended on the support frame by easily replaceable helical metal springs.
The vibration mechanisms consists of a shaft with highly resistant roller bearings, mounted on steel housings. The bearings are lubricated with grease and sealed against dust. The vibration intensity can be regulated with counterweights situated on the ends of the shaft, so we can increase or decrease their amplitude.
The Alquezar Grizzlies are equipped with upper solid steel grating, which makes them resistant to knocks and abrasion caused by classifying large-sized rocks.
