Slag Granulation Plant Process

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.

22/02/2019· CSIRO Dry Slag Granulation Process Overview. The CSIRO dry granulation process involves a two-step operation involving a granulator and a moving bed counter-current heat exchanger as shown in Fig. 1 . The granulator receives and atomizes molten slag to produce liquid droplets, which are rapidly quenched to become solid granules. The hot granules are fed

The technology of slag processing through granulation starts by effusion of slag from the Blast Furnace. The melted (liquid) slag at the temperature of 1300°C – 1550°C is led into the granulation chamber through a channel system (with an internal refractory lining).

The size distribution and the microstructure of the slag granules depend on process variables such as water jet pressure, angle between water spray and liquid slag flow. distance between water jet nozzle and liquid slag, viscosity of the liquid slag and the design of equipment.

granulation affiliated with dry granulation is the optimum process, with smaller slag particle size (about 2mm), more glassy phase and higher recovery rate. 1 Introduction

05/05/2013· The process of slag granulation involves pouring the liquid slag through a high pressure water spray in a granulation head, located in close proximity to the BF. Granulation process is the controlled quenching of the slag in cold water which does not give time for crystalline growth to take place.

The CSIRO’s Dry Slag Granulation (DSG) process is as a continuous -step prtwo ocess as shown in Figure 1. The molten slag is first atomized using a spinning disc and the fine droplets (< 2 mm) produced contact with flowing air and

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 Danieli-Corus. Paul Wurth already has more than 300 such

Based on the experimental results. a granulation plant is proposed to be built closely to the existing steel making plant. This study is part of a larger investigation work covering slag granulation

excess of those of a slag granulation plant. Processing of such slag-dumps is very labour intensive and costly, where crushing and screening plants are utilised to reduce the slag-dumps by either recycling or jigging to remove alloys, or to convert it into a backfill material or aggregates for other applications. Granted, slow cooling of slag renders it fit for removal of included alloys

The envisaged annual capacity of the plant is granulation of 530,000 tons of liquid slag. The plant for granulation of blast furnace slag is an addition made within the scope of the modernization project for the existing Blast Furnace, and is also part of the technological entity for production of crude iron. The technology of slag processing through granulation starts by

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. This proven granulation process ensures economic granulation and

[Images flash through of the process of dry slag granulation] What we’ve developed here is dry slag granulation. We can granulate the slag, produce a good quality product that can be used for cement manufacture but do it in a way that doesn’t involve water. [Image changes to show Mark Cooksey] If you use our products to produce cement for each tonne you use you

03/11/2021· A system analysis of advantages and features of the semi-industrial pilot HVG-plant showed that its operation for granulation of slag melts of ferrous metallurgy in enterprises equipped with modern arc electro-thermic ore-smelting furnaces is feasible according to the schematic diagram presented in Fig. 11, where 1 is arc ore-thermal furnace, 2—chute for

09/12/2019· Granulation is the most widespread method of slag handling, employed to a number of metals as well as practically all metallurgical slags such as copper , ferroalloy [14, 18], and steel [19, 20], and most widely for the BF slags . The principal reason for granulation is to achieve high cooling rates despite the low thermal conductivity of slag by decreasing the
