Abstract. An innovative process of preparing ironmaking burden – the composite agglomeration process (CAP) has been developed. In CAP, part or all of the fine grained iron bearing materials are separately made into 8–16 mm diameter green pellets in a balling disc or drum, and the rest of fine grained and all of the coarse grained materials are granulated after …

Blast Furnace – Minecraft Wiki
A blast furnace is a block that smelts ores, raw metals, iron and gold armor and tools, similar to a furnace. A blast furnace smelts items at a speed of one item every 100 game ticks (5 seconds) or twelve items per minute, which is twice as fast as a standard furnace. It also serves as an armorer's job site block. A blast furnace can be picked up by any pickaxe. If mined without a …

Sinter plant - Wikipedia
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the …

Development of Pellet-Sinter Composite Agglomerate for Blast Furnace
The cold crushing strength of the pellets separated manually from sinter mass was measured. The Table 8 indicates that CCS of the pellet was varying in the wide range of 15–110 kg/pellet while average was 60 kg/pellet. In order to minimize the variation in CCS the overall coke rate was increased to 5.5% from 5%.
