At bauma 2016, Hartl showcased its new bucket crusher that stood out for its capacity for high throughput and for the optimal shape of the produced end-material
The unique quattro movement of the jaw crusher, fitted with an up-thrust toggle system, provides and guarantees an overall performance, regarded as second to none.
Amongst the most important advantages is that the material is cracked in the upper area of the jaw crusher. This means bigger blocks can be taken and are crushed in a downward direction into the chamber — compared to the industry standard down-thrust toggle jaw crushers.
The special motion (like a figure eight) gives the crusher a better throughput profile in the middle area and a kind of secondary crushing in the lower area, providing an excellent cubical shape to the end material.
Independent screen analyses confirm Hartl a bad shape content of only six per cent, which means that all global regulations and quality standards are fulfilled with only one time crushing! Beside this, only premium components like SKF bearings, Parker hydraulic and central lubrication system, SAE hydraulic connections, etc. are built in.
Hardox steel is standard and constant quality control during all manufacturing steps grant for highest manufacturing standards. All finished products are obliged to go on a two hour test run on a special designed test rig where bearing temperature, oil flow, greasing, vibrations etc. are measured. Only after this procedure the products are allowed to leave the factory and be delivered to customers.
The bucket screener from Hartl features a strong and robust design, which makes it suitable for the hardest applications in prescreening as well as final separation. The absolute win in the design is the wide entry area with the optimised storage possibility for maximum load volumes. Material can be stored and with short moves constantly feed into the screener drum. This is increasing the performance, as swivel time is heavenly reduced. Also, a drop out and fall back of bigger material is prevented with this unique design.
All screen meshes are changeable and fast replaced when needed.
