Annular cooler for sale! The annular cooler is one of the indispensable machines in iron ore pellet plants. It is a crucial part of the grate-kiln pelletizing process. The grate-kiln pelletizing plant is composed of a traveling grate preheater, rotary kiln, annular cooler, disc pelletizer, etc

produced in a Grate-Kiln system are uniformly high quality. Hot pellets from the rotary kiln are discharged directly to the annular cooler where they are leveled to a uniform bed depth and conveyed over the primary and final cooling zones. 46 Straight Grate pellet plants designed 46 Grate-Kin systems with over 119 MTPA capacity installed worldwide

In the grate kiln, pellets are heated up to a temperature of about 800-900 °C in the preheating zone, then they finish the induration at roughly 1200-1350 °C. After that, all the iron pellets enter an annular cooler for cooling until reaching a normal temperature for further storage or transport.

annular cooler The grate has two or more wind boxes to provide for the gas draft Heat for drying and preheating is supplied by the gases discharged from the rotary kiln, and hot air from the cooler is utilised in the rotary kiln The pellet bed on the grate is only 150 -200 mm deep, and no protective

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 pressure of cooling air in the annular cooler varies from −4 to −130 Pa. The air flow velocity is higher on both sides than that in the center of the annular cooler, and the reason is the border effect of the side wall of the annular cooler.(3) The temperature field of the pellet bed in the annular cooler was also gained by simulation.

Forced 'Annular coolers' are located at discharge end to uniformly cool pellet by an updraft of ambient air before transporting to storage silo. THE CHALLENGE Grate Kiln process is unique process designed to evenly indurate pellets to increase its mechanical properties.

Refractories for Iron Ore Pelletizing Plant. In the sintering zone of rotary kiln at high temperature, iron pellets generate a low viscosity liquid phase on it, which causes the forming of a thick annular coating ring on refractory surface. Novaref's refractory castables and precast shapes for use in rotary kiln firing iron pellets are ...
