In -Pelletizing Process, Heat treatment stages (Induration section) are carefully separated as Travelling grate / Rotary kiln / Annular cooler and each unit is expected to optimally carry out a specific process function. This increases the plant availability and reduces the requirement for spare parts, resulting in low maintenance cost.

The kiln can be preceded by a travelling grate or shaft type pre-heater for preheating the feed in order to improve its fuel economy. When processing lump ore or burnt pellets, it is, in the final analysis, the price of fuel that deter-mines whether a grate or a preheater is used. Compared with the travelling grate
Pelletizing System - Kobe Steel acquired the license of Grate-Kiln process in 1995 and our own brand Pelletizing System was born.

Dec 06, 2014· Travelling grate: A moving grate which is covered with a fuel layer, 10-30 cm. Power control by means of varying the grate velocity Reciprocating grate: For ash-rich, low calorific fuels like municipal waste, arrangement of stationary and moving grates -> conveying and mixing (forward-moving type or reverse-action grate)
A horizontal travelling grate conveyor feeds the debris to the crusher. The rapidly rotating hammer roller positioned above the conveyor crushes the material. du c a ti on l bj ev f h p r Mechanical separation includes different types of sorting and separation methods.
Mar 27, 2016· It is the heating stage in the pellet making process. The correct sized green pellet coming out of the balling discs are indurated to a compressive strength of 250kg/sq. Meter on a straight travelling grate having a reaction area of 4m wide*116m long*. The travelling grate consist of an endless chain of pellet cars that continuously move on tracks.
Providing a better tool for understanding effects of solid flow and mixing by a traveling grate The drying, volatilization, and combustion phenomena during the travel of the solid waste fuel over the grate depend on a large number of parameters Physical Model: 2 reciprocating bars and 2
Apr 23, 2014· The Pelletizing System is a grate-kiln process where iron ore pellets undergo heat treatment in two stages. Iron ore and binding agents are ground and formed into "green balls," the unfired pellets. The green balls are sent to a traveling grate where they are dried and preheated in the preheating furnace.
32 Chain Grate Stoker A diagram of a chain grate boiler is shown in Fig. 9.4 (next slide). The coal is supplied by the travelling grate and the thickness of the bed controlled by the guillotine door. The speed of the grate and an air damper setting control the firing rate.
