Mar 15, 2020#0183;#32;A novel atomization process based on a rotary cup atomizer (RCA) was proposed to manufacture iron powders using semisteel as the raw material. To achieve rapid cooling of iron droplets and efficient separation of iron powders from cooling water, a circle of water curtain was set around the RCA in the experimental setup.
At the present molten slag from a blast furnace () is granulated by impinging much water without any recovery of its much sensible heat (1 823 K) polluting water and atmosphere. To solve these problems, the dry granulation of molten slag by Rotary Cup Atomizer (RCA) was studied, in which the influence to the rotation speed of the RCA on slag drop size was mainly examined.

Jan 25, 2017#0183;#32;As with atomizer design for the treatment of blast furnace slag rating up to 10,000 t/d, the required atomizer radius decreased to m by employing cuplike atomizer instead of disclike atomizers at 1500 rpm. And the cuplike atomizers provided a possibility to
Abstract. At the present molten slag from a blast furnace () is granulated by impinging much water without any recovery of its much sensible heat (1 823 K), polluting water and atmosphere. To solve these problems, we studied the dry granulation of molten slag by Rotary Cup Atomizer (RCA), in which the influence of the rotating speed of the RCA on slag drop size was mainly examined.

Dry slag granulation presents an opportunity to simultaneously generate a glassy slag and recover the sensible heat. The rotary multinozzles cup atomizer was proposed to granulate the molten slag at...
At present,molten blast furnace slag is widely granulated by water quenching method,which not only consumes a large amount of water,but also can''t recover the sensible heat,and water and atmosphere is polluted as Cup Atomizer(RCA) is a dry granulation,which can solve the abovementioned for blast furnace slag by rotary cup atomizer was studied for how it is
This paper describes the hot experiments where a rotating multinozzle cup atomizer (RMCA) is used to atomize the molten blast furnace slag without water impingement.
A novel atomization process based on a rotary cup atomizer (RCA) was proposed to manufacture iron powders using semisteel as the raw material.

Feasibility of Rotary Cup Atomizer for Slag Granulation. Rate of Methanesteam Reforming Reaction on the Surface of Molten BF Slagfor Heat Racovery from Molten Slag by Using a
The analised dry granulation process is to atomize the molten slag and then to cool the particles rapidly so as to produce a glassy slag. The atomization is done using a rotarycup, airblast atomizer. The particles cool as they travel through the air and then cooled further in a fluidized bed.
The Rotary Atomizer is the key component in a spray dryer plant and it is vital that every service performed on it is a masterpiece. With a team of very skilled technicians we can offer our competency to keep your atomizers fully operational.
Mizuochi et al. [6] investigated the feasibility of the rotary cup atomizer for slag granulation, and found that the BF slag droplets were strongly dependent on the rotating speed of atomizer

Aug 09, 2014#0183;#32;A rotarycup, airblast atomizer was built, with a cup of 100 mm diameter and a speed range of 500 1500 rev/min. The slag flow rates used in the tests varied from kg/sec to kg/sec. The tests were restricted to duration of about min because of the limited capacity (around 30 kg) of the laboratory slag melting furnace.
