HAZEMAG redefines the secondary crushing technology
The new HAZEMAG concept unites our know-how of more than 60 years combined with the practical experience and the demands of the plant operators. The HSI series has been designed for the economic secondary crushing and, depending on its configurations, processing of either soft and medium-hard or hard rocks is effected.
It is a modular system with the objective of fulfilling every scope of work in the bulk goods industry. The machine’s fittings as well as its control may be modularly adapted to the individual requirements and wishes of the 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 t/h 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.
The rotor is the key component in the crushing process. The optimum rotor type is selected according to the crushing requirements and the characteristics of the feed material. The blow bars are locked in position in the holders by means of wedges, which can be easily removed for blow bar changing.
The rotor body together with shaft and bearings forms the "heart" of the impact crusher.
With the HAZtronic system, the crusher can be controlled and adjusted from the main control panel. All the settings which determine the end product can be input and called up at the touch of a button without interrupting operation. This means that immediate reaction and adjustment to varying operating conditions can be effected at all times to ensure optimum productivity.
