coal slime and studied the effects of coal slime on the slurry ability of a semi-coke water slurry (Meng et al., 2020). Coal slime can replace clay as raw material or auxiliary material for cement production, providing necessary silicon and aluminum components (Qiu et al., 2010; Yang et al., 2016). Coal slime

In this paper, the process of direct reduction roasting using magnetic separation to produce direct reduction iron (DRI) from high-phosphorus oolitic hematite, using coal slime and blast furnace dust as reductant, is investigated. The possible use of slime coal and blast furnace dust as reductant and the dephosphorization behavior during the process of …

Why make coal briquette During coal mining, transportation, and processing (crushing, grinding, or pulverizing), a lot of coal fine and coal dust will be produced, especially in modern mining operations, advanced equipment will lead to more coal dust. It is a very good recycling method to make these dusts into briquettes.

Working principle of coal press machine. The charcoal briquette machine makes powdered raw coal into different shapes. Its working principle is: the electric motor transmits the power to the transmission through the belt pulley to drive the propulsion shaft to work, and the screw propeller on the propulsion shaft pushes the coal material and pushes it through …

ABSTRACT Coal slime, coal slime/CaO, and coal slime/CaO/pine sawdust were formed to make briquettes respectively. The effects of pine sawdust on the SO2 retention by CaO during coal slime briquette combustion were studied using a tube furnace. The obtained results demonstrated that porous structures were created in the …
