HGT gyratory crusher integrates mechanical, hydraulic, electrical, automation, intelligent control and other technologies in one, and benchmarks the international advanced gyratory crusher technology. It is a new type of coarse crushing equipment with large capacity, high efficiency and intelligence. Compared with the traditional gyratory crusher, the HGT gyratory crusher has higher crushing efficiency, low use cost, and convenient maintenance and adjustment, which can provide users with efficient and intelligent super-capacity coarse crushing solutions
On the basis of the traditional multi-cylinder hydraulic cone broken main shaft fixed, eccentric sleeve rotating structure and lamination crushing principle, the HPT multi-cylinder hydraulic cone crusher structure has been optimized through breakthroughs, which has significantly improved the performance And the crushing capacity; and the supporting design of the hydraulic lubrication system to ensure that the equipment operates more intelligently and reliably.
C6X jaw crusher equipment structure, use function and production efficiency and other indicators reflect the modern advanced technology level, which solves the problems of low production efficiency and difficult installation and maintenance of existing jaw crushers on the market. It is an ideal rough Crushing equipment.
The vertical mill is a new type of ultra-fine grinding equipment independently designed by our company based on ordinary vertical mills based on ordinary vertical mills, using current advanced Taiwan grinding roller technology and German powder selection technology. The vertical mill integrates ultra-fine grinding, grading and conveying, and is an ultra-fine milling equipment with excellent performance.
Our company has developed the fifth-generation pendulum suspended roller mill with several inventions and technologies-MB5X series pendulous suspended roller mill based on the accumulation of more than thirty years of on-site field test data and experimental analysis. It represents today's advanced cantilever milling technology, and is suitable for all kinds of non-flammable and explosive brittle ores with Mohs hardness below 7 and water content below 6%.
In response to the increasing demand for large-scale, intensive, energy-saving and environmental protection, and high-quality machine-made sand in the sand and gravel market, our group has further optimized and designed the structure and function of impact breaking on the basis of thousands of impact breaking sand shaping applications A new generation of high efficiency and low cost sand making and shaping equipment --- VSI6X series vertical shaft impact crusher (also known as sand making machine).
