Dec 11, 2020#0183;#32;Therefore, systems for the slag granulation have been developed. High content of slag in the granules is provided. granulation water system will increase, which could result in
The granulated slag samples were collected from the water granulation system at No. 6 blast furnace at East Japan Works (Chiba District), JFE Steel Corporation. Figure 1 shows the outline of this water granulation system. 12) The slag was recovered with sampling equipment set up between the conveyors at the outlet side of the dehydrator. Samples weighing about 20 kg were collected at 20
May 17, 2019#0183;#32;Slag granulation system produces granulated slag, which is mainly used as a raw material for cement and concrete aggregate, by quenching molten blast furnace slag with water. Paul Wurth Group (hereinafter PW) has more than 260 references worldwide for the supply of slag granulation systems and INBA dewatering drums.
The water processing system for blastfurnace slag granulation comprises a condensing tower, a granulator, a dewatering drum, a water collecting tank, a sedimentation tank, a lift pump, a cooling tower, a cold water tank, a condensed water supply pump, an overflow pipe and a water supplement pipe of the system, wherein the height difference
Method of Water Granulation Experiment In the water granulation system, the flow rate and temperature of the molten slag, which flows out of the tapping hole of the blast furnace, change with time from the start of tapping. Therefore, it is difficult to evaluate independently the influence of the water/slag ratio and blowing water tem
Dry Slag Granulation. Water granulation is the most commonly used method to handle blast furnace slag and requires a granulation and a dewatering step to process the slag. In water granulation, the energy in the slag is lost from water evaporation and cooling and is difficult or impossible to recover.

Tenova Pyromet has vast experience in the design and construction of wet granulation plants. The wet slag granulation process involves pumping water into the slag cold runner via a blower box to quench the molten slag. The inhouse designs have been proven in numerous applications and have shown to be both robust and reliable.
Jun 01, 2016#0183;#32;A prototype dry slag granulation system was proposed and designed in commercial scale. The input and output flows of each slagtreatment system were identified. Life cycle assessment on the dry slag granulation method and water quenching methods was carried out. Economic costs and returns during the lifetime of slag were calculated.
There are various processes on the market for the granulation of blast furnace slag. The most important process is cooling in a water bath. The most common methods are the RASA system from Rasa Corporation, the INBA system (Fig. 16) from Paul Wurth, a company of the SMS group, and the IJ GRAN system from DanieliCorus.
Granulation, dewatering and storage of the slag can be done adjacent to the furnace or can be split up to suit available plant space or logistics. Modern condensation concepts and closed loop water circuits ensure effective environmental INBA system with steam condensation is officially recognised as a Best Available Technology (BAT).

The slag granulation plant comprises three sections: for granulation, dewatering and storage. In the granulation section, the liquid slag is quenched by pouring onto it an excess water stream. The evaporated water will be condensed in a condensing tower located above the granulation tank.

The granulated slag and water mix is distributed evenly over the whole length of the drum. Axial vanes inside the drum continuously lift the slag sand onto a conveyor belt for immediate evacuation. The fine mesh on the exterior of the drum retains the slag sand and allows the water to filter through. The slag
May 05, 2013#0183;#32;Fig 4 Schematic diagram of a slag granulation plant. Granulation section Here, the liquid BF slag is water quenched and solidified into small particles, eliminating the need for heavy crushing equipment. The liquid slag flows by runners from the BF to the granulation unit. From the runner, the liquid slag stream at around 1,500 deg C is poured into a high velocity water stream at the
The slag granulation system of claim 1 wherein the at least one hydrocyclone is a plurality of hydrocyclones mounted in parallel, with valve means in the water suspending fine slag particleconducting conduit means for the hydrocyclones whereby any one, combination of any two or more but less than all when more than two hydrocyclones are
When slag is quenched with water, the high energy potential of liquid slag is wasted to heat and evaporate water. For granulation, the circulated water has to be recooled in cooling towers or with other cooling methods. Mainly cooling towers are equipped with electrically operated fans and also the cooling water circulation system consumes
