Hazemag HSI Impactor Designed for Economic Secondary Crushing

The new Hazemag HSI series has been designed for economic secondary crushing and, depending on its configurations, processing of either soft and medium-hard or hard rocks.

It is a modular system with the objective of fulfilling every scope of work in secondary crushing circuit. The machine’s fittings as well as its control may be modularly adapted to the individual requirements and wishes of its operators – even up to a fully automatic mode.

Depending on the properties of the feed material, the crushing ratio and the desired requirements on the product grain size, feed sizes of up to 450 mm and throughput rates of 700 tph max are possible.

Due to the hydraulic suspension of the impact aprons, not only a simple and fast adjustment of the opening widths is guaranteed, but also an overload protection. As soon as the crushing forces in the crushing chamber exceed a predefined limit value, the impact aprons retract and thus protect the built-in parts, such as rotor, blow bars and impact aprons, from potential damages.

After the retracting procedure, the impact aprons move back in a controlled manner into their original position, so that the crushing operation can be continued without interruption.

In addition, the hydraulic suspension offers the comfortable possibility of a simple readjustment and a quick on-the-spot-adaptation to the individual procedural conditions on the machine or from the switchboard.

The HSI series may optionally be fitted with a grinding path. The grinding path restricts the amount of oversize and supports the generation of a cubical and stress-free product.
