Pulverization Rate Decreasing Binder of Sintering

Product Description:

Jianjie® organic binder for sintering is a composite material synthesized by adding some organic polymer materials, and has the properties of hydrophilicity, complexation and high bonding. It can effectively replace the CaO, and is widely used in iron ore sintering.This type of binder can decrease the pulverization reate of sintering and rise the production efficiency of sintering  machine.

Product Characteristics

This product is specially developed for pellets of various iron ore powders, and has high water-absorbing swelling and bonding properties. The amount added during use is far lower than the traditional bentonite binder; furthermore, the green pellet has high compressive strength and strong drop resistance.

The iron grade of the pellets after baking is higher than that produced by traditional binders; the thermal stability of the furnace is good, which reduces the low-temperature reduction pulverization ratio and the amount of powder, which is beneficial to blast furnace operation.

Compared with traditional bentonite binder, the content of silicon and aluminum is lower, and the porosity is significantly improved, which is beneficial to redox and reduces the energy consumption of production.
