Sandvik crushers producing in Korea

In recent years some of Korea’s leading aggregates producers have started to invest in Sandvik crushing equipment. There were now further orders from Korean companies for CH430 and CH440 cone and CV229 VSI crushers, all equipped with ASRi. One such company is Wooryung, which is using a recently acquired CH430 cone crusher to produce a 30 mm product from a <150 mm feed material (Fig. 1). The CH430 is located at the company’s site in YoungWol, in KangWon province, with the crushed limestone being supplied to a steel company after desulfurization.

Introduced in 2002, Sandvik’s line of autogenous crushers, of which the CV229 is one of the more recent developments, utilizes a rock lined rotor to accelerate material. This is then impacted in a highly energized rock lined crushing chamber and it impacts with material falling through the biflow system. The crushers incorporate the Sandvik Hurricane™ rotor, which became a major breakthrough in VSI autogenous rotor design due to its decreased vibration levels and wear part design, which results in increased crusher bearing life combined with reduced maintenance. Standard Sandvik VSI crushers are fitted with a timed trapped two key system, which ensures the safety of maintenance personnel combined with electrical isolation. Also supplied and fitted as standard, are a vibration detection switch and a pre-start alarm siren.

These features have been particularly useful to one such Korean company as a shortage of sand in its natural form has presented Bokwang with the opportunity to use its existing aggregates to help satisfy the needs of the Korean construction industry.  This is achieved through not only being able to supply a manufactured sand product, but also by being able to improve on the naturally occurring sand (Fig. 2). How this is accomplished is due to manufactured sand possessing significant benefits over the naturally occurring form, as it originates directly from high quality virgin rock, and thus contains very few, if any, contaminants that are found in naturally occurring sand.

There are also significant advantages to be gained from the cubical shape of the end product produced during manufacture, which further provides advantages during cement manufacture, and hence benefits the construction industry as a whole. Hence the Sandvik CV229 is now proving its qualities by producing sand from aggregate with Bokwang using the VSI at its site in KwangJoo, KyungGi province. The <35 mm aggregate is fed into the CV229 to produce a finished product of <5 mm, which is then used as sand.
