HAZEMAG has announced the sale of the HAZEMAG roller crusher HRC 0810 (565 t/h) for the production of kiln stone in Brazilian magnesite applications. The hydraulic retraction and gap adjustment system will work in conjunction with the optical belt particle size analyzer and allow adjustment of the crusher gap settings to compensate for wear. The crusher will use HAZconnect technology, allowing HAZEMAG's control and software engineering team to remotely access the machine. Combined with its augmented reality service tools, HAZEMAG said that it can now help customers around the world even in situations where it is impossible to travel.
HAZEMAG cites the advantages of its roller crusher product line (including models ranging from 105 tons/hour HRC0605 to the largest 6,500 tons/hour HRC Rate. Intelligent design, metal debris protection, automatic gap setting, simple maintenance, and a variety of crushing tools. It produces cube products with minimal fine powder, while providing trouble-free operation when handling very viscous and wet materials. Maintenance attributes include rotation and slip monitoring of the crushing roller. Monitoring of bearings and gears, track roller lifting device. Even in the operating position, the crushing section can be quickly replaced, as well as the adjustable scraper.
The company said: “The working principle is based on the continuous pressure generated between two counter-rotating rollers, so compared with intermittent jaw crushers, the crushing process will not be interrupted. During operation, the crushing rollers and drive components The high rotational energy ideally reduces the peak load and achieves uniform power consumption. If unbreakable debris enters the machine, the crushing gap must be opened to let the debris pass. This is achieved by using so-called floating rollers, floating The roller is supported on the swing rocker arm. The rocker arm is supported by the lower shell through a hydraulic cylinder. To ensure that the floating roller retracts in parallel, the rocker arms are connected to each other through a torsion shaft. The rotating response of the floating roller allows almost frictionless movement and large Escape path. The housing and drive bracket of the HAZEMAG roller crusher are very sturdy and therefore suitable for heavy applications. They are equipped with easily replaceable wearing parts. The design of the housing allows the crushing section to be replaced under the hopper with an easily removable cover ."
The driving device is installed on the base, which is connected with the roller crusher. The floating roller driver, which is also pivotally supported, is connected to the floating roller rocker arm through a connecting rod. It is thus ensured that there is a constant belt tension during the retracting movement of the dancer roller and during the gap adjustment. The crushing rollers of the primary and secondary crushers are composed of polygonal-designed roller bodies, which are equipped with replaceable crushing sections. Due to the specific geometric shape between the roller body and the crushing section, an optimal tight fit is achieved, which can withstand high crushing forces. According to their respective task definitions, choose the shape and number of teeth.
Using the CPU provided by the standard, the crushing gap can be controlled and checked from the switch center and the switch cabinet on the crusher, thereby controlling and checking the product. In order to compensate for the wear of the crushing tools, the crushing gap can be reduced very easily by pressing a button.
