2017-5-91.V type of crushing chamber, effective opening size is equal to the nominal opening size (common jaw crusher adopts the traditional asymmetric crushing chamber structure, and effective opening size is smaller than nominal opening size)and the throughput capacity will be increased by15-20% compared with the normal crushing chamber

The existing BF design makes an operation without coke impossible. Chernov suggested in 1940s to separate in the BF zone of solid-phase reduction and zone of melting without excess of solid carbon and developed a coke-less BF design (Chernov, 1950). Further iron-making development took the other way of alternative to the BF direct and smelting reduction processes. Later on, Tovarovsky developed further the Chernov's coke-less BF considering already the Corex experience (Tovarovsky, 1994). In this BF, said the shaft-hearth aggregate, the iron oxides are reduced in solid phase up to metallization degree of 7585% in shaft and bosh by reducing gas, introduced in shaft at t<900C (Figure 17.33). Hot reducing gas from the tuyere zones 5 is mixed with cold reducing gas injected via tuyeres in shaft 6 to get the temperature of about 900C

Currently all production is sourced from the VCR (Ventersdorp Contact Reef). The mine has been expanded through many deepening projects with the latest one being the extension from 109 to 120 levels. Work is currently in progress to extract the ore from the Carbon Leader Reef (CLR) below it

This little stunner, with its postmodern influence and bold shape, is surprisingly flexible. It could be at home on a frightening ziggurat side table in Catherine OHaras Beetlejuice mansion or on an impeccably curated bookshelf in a tony Litchfield County estate. It works best if youre aiming for a dainty complement to a composition of books and vessels on your nightstand but are hoping for a piece with strong character and a playful sense of geometry
