HAZEMAG HTI – the innovation for the production of crushed stone fines and high-quality stone chippings.
Due to the continuous pursuit of procedural, maintenance and user-friendly improvements, a new development emerged in the field of tertiary machines: The HAZEMAG Tertiary Impact Crushers of the HTI series. The new HAZEMAG concept for tertiary crushing unites our know-how of more than 60 years, combined with the practical experience and the requirements of the plant operators.
The HTI series was designed for the economic tertiary crushing of hard rock and is a modular system with the objective of fulfilling every task in the bulk materials industry. The machine’s fittings as well as its control may be 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 150 mm and throughput rates of 160 t/h max. are possible.
The hydraulic suspension of the impact apron offers the comfortable possibility of a simple adjustment of the gap setting and a quick adaptation to the individual procedural conditions.
For service, inspection and maintenance work the machine’s housing is fitted with large doors on both sides. The blow bars are laterally inserted into the rotor, so that they can be simply and quickly exchanged. The housing’s plating largely consists of handy and easy to exchange wear plates.
The new design of the HAZEMAG HTI series considers the standardization of the wear parts. An economically interesting exchange of the wear parts is guaranteed. Due to the use of especially wear-resistant blow bar materials and designs with a degree of utilization of more than 50 per cent, the operating and maintenance costs of the HTI series are clearly reduced. Because of the symmetrical design of the HTI Impact Crusher the rotor’s direction of rotation may be reversed. This feature has a positive effect on the crushing behavior and the service life of the wear elements. Due to the reversing procedure an automatic regrinding of the blow bars is effected, which entails a constant crushing product and a uniform degree of utilization. The design of the crushing chamber of the HTI series with the comfortably adjustable impact apron gap ensures an optimum crushing result at a favorable energy demand.
The HTI 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.
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.
The rotor of the Impact Crusher is generally the most stressed component during the crushing procedure. Depending on the crushing problem to be solved, two types of rotors are available for the HTI series.
+ HAZEMAG machines have excellent accessibility to facilitate servicing and maintenance work and thus minimise down time. Moreover, the tools and personnel required for such tasks are reduced to a minimum.
+ The crusher housing is lined with handy and easily replaceable wear plates, of which some 97% are interchangeable, thus reducing storage space and costs.
+ All impact crushers are fitted with a key transfer system, which prevents unauthorised opening of the housing during operation and prevents motor start-up whilst work is being carried out on the open crusher.
+ The modern and generously-equipped fabricating facilities in the Dülmen works guarantee machines and products of the highest quality.
+ Installation, repair, modification and assembly work is carried out by highly-trained and experienced personnel, if necessary in shift work around the clock. Of course, as part of the service, HAZEMAG offers contracts for after-sales inspection as well as for the acquisition of spare and wear parts.
