The influence of chromium slag on the compressive strength of the red mud-based geopolymer was tested. At 3 d age in Fig. 4 a, as the chromium slag content increased from 0 wt% of R7G3-C0 sample to 10 wt% of R7G3-C1 sample, the compressive strength increased from 12.27 MPa to 15.73 MPa. The reason for the promotion effect …
Virtually all charge chrome plants now use the crushing/jigging process to recover chrome alloy from both stockpiled and currently produced slag. Studies were carried out at R&D, Tata Steel to develop a flow sheet for the recovery of metal from metal–slag mix generated in its charge chrome (ferrochrome with 50–60% chromium) …
The skyrocketing demand and progressive technology have increased our dependency on electrical and electronic devices. However, the life span of these devices has been shortened because of rapid scientific expansions. Hence, massive volumes of electronic waste (e-waste) is generating day by day. Nevertheless, the ongoing …
Steel slag uniformly enters the jaw crusher through a vibrating feeder for coarse crushing treatment. After coarse crushing, the steel slag enters the vibrating screen for screening into materials of different particle sizes. If it does not meet the particle size requirements, the materials will return to the crusher machine for crushing.
Today, we have proud to say that we have designed and develop the frst ever metal chip recovery slag crusher plant in India. To develop the slag crushing plant is the big achievement for Bhupindra Machine Pvt.Ltd. We have developed the 100 TPH fully automized slag crushing plant on key basis.
The effect of calcium oxide on the crushing strength, reduction, and smelting performance of high-chromium vanadium–titanium magnetite pellets (HCVTMP) was studied in this work.
Benefits of sensor-based slag metal sorting at a glance: Free metal recovery: Separating non-magnetic metallic particles effectively means earning revenue at low cost. Disseminated metal concentration: Concentrating metal containing slag particles before it undergoes separation, through crushing and jigging, protects crushers at little expense.
