a new Hydrocone® crusher with hi-tech strength
H7800 a new Hydrocone® crusher with hi-tech strength SANDVIK ROCK PROCESSING Increasing A BIG DECISION Investing in a new crusher is always a big decision. Since your crusher does not operate as an independent unit, but is often part of a production chain containing many different links, buying a new piece of equipment requires careful consideration – not least regarding its efficiency and economy. That’s why we at Sandvik Rock Processing have gone right back to the drawing board to design a new Hydrocone ® crusher, to produce a machine which delivers really significant benefits over and above those of your existing equipment. H7800 is the first of a new generation of crushers with what we call ‘hi-tech strength’. SIZE ISN’T EVERYTHING In the past it was assumed that the performance of a crusher could be measured in relation to its weight. A heavy crusher was synonymous with a heavy-duty crusher. However, the arrival of H7800 challenges this assumption, so mine and plant owners and operators can afford to think differently. H7800 gives enhanced performance in relation to size and weight. It looks like a medium-sized crusher, yet it has all the strength and power of a much larger crusher. So, it’s time to accept that size isn’t everything after all. 2 PRODUCTIVITY When your goal is to increase productivity at an existing site, there are several important factors to take into consideration: the cost of new equipment and how to install it, versus the increase in productivity it will deliver. Being a neat, compact crusher, H7800 fits in nicely where space is limited, and it gives you a high level of performance in relation to its size. It therefore provides a cost-effective boost to production at your existing operation, enabling you to utilize existing infrastructure such as foundations, buildings and material handling arrangements. THE RIGHT LEVEL OF PRODUCTION Whilst a modern crusher enables you to boost production, it obviously needs to be synchronised with the rest of your plant or line. In terms of production volume, H7800 lies between H8800 and H6800 (Sandvik Hydrocone models or similar), giving you levels of production that are highly efficient, with excellent space/weight/performance ratios, yet not overproducing in such a way as to create bottlenecks in your downstream processes. BETTER REDUCTION In H7800, two important factors combine to give greater reduction - new crushing chambers and the automation system ASRi™. Power is used to improve reduction rather than just increase capacity, so you get a better quality product in relation to the energy consumed. The product is simply more efficiently reduced. Working in combination with the ASRi crusher control system, circulating load is kept to a minimum. Your crusher is always working at its upper limit, giving you optimum performance whilst preventing overloading. 3 DESIGNING WHAT CAN H7800 H7800 from scratch do for you? Why does H7800 look different from other members of the Hydrocone® family and what are the advantages of this new design? The fact is that in addition to having all the know-how and experience needed to refine our Hydrocone crushers’ design, we also use the latest advanced engineering tools. So in creating H7800 our designers were able to rethink the basic principles of crusher design from scratch, developing a different shape, applying new materials and finishes, and strengthening the crusher’s important points. 4 THE RESULT IS that in H7800 you get a lighter weight crusher with hi-tech strength, i.e. strength in all the right places. We put in 520 kW (700 hp) of power and this fact, in combination with a greater shaft travelling height (to facilitate the elimination of tramp metal) accounts for its weighty bottom shell. THE TOP MOUNTING of the hydraulic components in the oil tanks also represents a new approach. It makes servicing far more tidy as oil doesn’t spill. In addition, the lubrication tank and the Hydroset tank are divided into two separate units. This means they can be placed in different locations, optimising available space. A plexi-glass window has been fitted in the oil tank making it easy to see oil flow and condition and notice at a glance if the oil levels are low. Sandvik as a leading innovator For over 100 years we have been making crushers, and for 30 of those, we have also been developing crusher control systems to optimise the performance of our crushers. With H7800, we demonstrate once again that Sandvik is the leading innovator in the field of rock processing, taking crusher design technology combined with advanced crusher control to new heights. H7800 is a genuine innovation in rock processing equipment from Sandvik, building on the strength and robustness of our proven Hydrocone® crushers. • It can improve your production capacity. Thanks to the new design described above, even if H7800 is not a large crusher, it has strength in all the right places. • It can handle the toughest minerals processing applications in mines and processing plants. H7800 was specifically designed to operate 24 hours a day in mining and aggregate applications, the toughest job in the business. This is the best guarantee of the crusher’s ability to handle heavy-duty applications. • In designing this new crusher, operators’ feedback has been taken into consideration. Easy maintenance is an issue we take particularly seriously, hence the positioning of the dump valve at the side of the machine and the design of the oil tank, which is made for easy servicing. • Change wear and spare parts with minimum downtime. For example, the liners of H7800 do not require any backing material like plastic epoxy or zinc. This saves the time usually spent mixing, pouring and waiting for the curing to take place, whilst also increasing safety for your maintenance staff. • H7800 generates downstream process savings in cost and efficiency, thanks to better reduction, promoted by a new chamber design and by the use of ASRi crusher control system. • It handles tramp metal more effectively. H7800 is designed for a greater shaft travelling height and this facilitates the relieving of incidental tramp metal. ASRi ensures that the shaft is returned at the right moment to its former position. • Gives you enhanced control and protects your capital investments. H7800 comes with a built-in TIMS™ (Tank Instrumentation Monitoring System) a small control unit designed to check lubrication, temperature and oil flow. TIMS automatically watches all functions like switching on cooling fans and heaters when necessary. It also eliminates most of the local installation work and provides enhanced control with a full factory guarantee. • Enhanced performance through compatibility with our ASRi crusher control system. Used in combination with H7800, ASRi gives you a continual flow of information and constantly makes adjustments leading to more efficient production. For example, it adjusts crusher settings automatically in order to compensate for the liner wear; it ensures the highest possible crusher performance. Pressure and power in relation to load are automatically adjusted to suit rock properties, moisture etc. All influencing conditions are taken into consideration, 24 hours per day, keeping your crusher pushed up to its 100% performance, automatically. 5 ø2507 Inlet ø2200 TECHNICAL FEATURES Approximate weights H7800 of H7800 Heaviest lift during maintenance: 13000 kg Weight (excl. motor): 50 Tonnes Total weight (incl motor & subframe): 58 Tonnes 8 H7800-EC 10 13 16 19 22 300 H7800-C 240 H7800-MC 195 H7800-M 155 H7800-MF 100 H7800-F 90 H7800-EF 80 520 550 25 29 32 38 44 51 57 64 70 980 1060 1120 1240 1350 1490 1610 1740 1860 1030 1110 1180 1300 1420 1570 1690 1830 1960 990 1060 1140 1200 1330 1460 1610 1730 1880 2010 1330 1470 1580 1720 850 910 970 1040 1100 1220 770 830 880 940 1020 1070 1180 700 760 810 870 920 1000 1050 1160 600 650 690 740 790 850 900 990 378 C.S.S.

They apply for open circuit crushing of dry material with a bulk density of 1600 kg/m3. It is assumed that material much finer than the crusher’s closed side setting (CSS) is removed from the feed. Consult us regarding the application of the crusher since the chosen eccentric throw, degree of reduction, the material’s crushability (Wi) the size analysis of the feed, the design of any recrushing circuit and the moisture content in the feed all affect performance of the crusher. 1228 ø625 Product curves The product curve and the percentage of the crusher product that is smaller than the closed side setting (square hole, mm) is dependant on the crushability (Wi), of the material, the size distribution of the feed and other factors.
