Abstract

The invention discloses a crushing and grinding device for steelmaking slag. The crushing and grinding device comprises a grinding device main body, an electric telescopic rod, a telescopic rod mounting rack, a grinding motor, a screw conveyer and a grinding plate, wherein a grinding chamber arranged at the upper part of the grinding device main body and a powder collecting chamber arranged at thelower part of the grinding device main body are arranged inside the grinding device main body; a telescopic rod mounting groove communicated with the grinding chamber is formed in the center of the top surface of the grinding device main body; the telescopic rod mounting rack is welded on the top surface of the grinding device main body; and the telescopic rod is arranged at the bottom of the telescopic rod mounting rack. According to the crushing and grinding device disclosed by the invention, the telescopic rod rotates and extends to drive a pressing plate to downward move, and steel slag is enabled to support against the surface of the grinding plate and is extruded and crushed; and the grinding motor rotates to drive a rotating shaft to rotate and to further drive the grinding plate to rotate, so that crushed steel slag is ground, and the whole steel slag is directly processed to form steel slag powder.

Description

technical field [0001] The invention relates to the technical field of steelmaking equipment, in particular to a crushing and grinding device for steelmaking slag. Background technique [0002] Steelmaking slag refers to the general term for the products formed by the physical and chemical reaction of the oxides formed by the impurities in the metal material (hot metal and scrap steel, etc.) Slag has a lower density than molten steel and usually covers the surface of molten steel. The main task of steelmaking is to remove harmful impurities (sulfur, phosphorus, gas and inclusions, etc.) and temperature. [0003] About 10% of scrap iron and steel and small steel balls contained in steel slag can be recovered by crushing steel slag and magnetically separating 8%-9% of which 70% can be returned to steelmaking production, and 30% is in the state of concentrate powder for use in In sintering production instead of concentrate powder. If the steel slag is dumped directly, it wi...
