GrateKilnCooler process simplifies the process control. When required, the burner has ability to simultaneously fire two fuels, gas and oil, and switch onstream from one fuel to another.
grate cooler. dear engineers.... we have a prolem in our cooler (claudius peters). we are frequently facing that problem, the problem is, at the kiln discharge end of grate cooler more red hot clinker is leaking to the hopper.
the interaction between this and the outflow system (overflow or grate discharge). The current typical drum agglomerator size selection, process considers the physical selection of the agglomerator geometry and drive power.
GrateKiln Process – Iron Ore Pelletising – Caiman Corporation There are two major processes for the production of Iron ore pellets: Straight Grate . GrateKiln technology.
The objective of this paper is to optimize the parameters of pellet drying and preheating process in grate. A mathematical model of drying and preheating is developed, and is verified by the experiments. Further, the operating parameters of wind temperature, wind speed, grate speed and bed depth etc ...
The shape of the pellets is imparted by the agglomeration process universally used for iron ore pelletizing balling. In balling, the ore fines ... of combustion through the kiln to the grate's preheat furnace and then downwards through the preheating bed. The preheat fans then discharge to
This ported kiln technology has more recently been coupled with AMS` GRATEKILN System for iron oxide pelletizing into the GRATECAR Process, for minerals reduction. The GRATECAR Process can handle a fine grained ore concentrate through the steps of agglomeration, induration and reduction in a single production line.

This master thesis uses process modelling to investigate energy efficiency measures in the gratekiln process for iron ore production; specifically, how waste heat contained in flue gas could be recirculated in order to achieve a decrease in specific fuel consumption.
Agitative agglomeration is the process of the consolidation of particles into larger shapes by means of agitation with a liquid. Most fine powders can readily be formed into granular masses by admixture with a liquid and by utilizing a suitable agitation method.

Slag formation in the gratekiln process is a major problem for ironore pellet producers. It is therefore important to understand the slag formation mechanism in the gratekiln production plant.
Abstract. A mathematical model of the grate/kiln process for the induration of iron ore pellets, verified for an operating plant, has been used to investigate the effects of process variables on fuel and power consumption, and on certain key temperatures and flowrates.
In GrateKiln system, GrateKiln considers 150 to 175mm of Green balls bed depth where as SG design considers a Green balls bed depth of 400 to 450mm. The Process fans need more power to suck or push the air through higher bed depth resulting in much higher fan power requirement.
