Title:
NOVEL COAL GRINDING DEVICE FOR THERMAL POWER SYSTEM OF POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2017/143543
Kind Code:
A1
Abstract:
A coal grinding device for a thermal power system of a power plant comprises a housing (4), a coal inlet and outlet mechanism disposed above the housing (4), a first driving mechanism disposed below the housing (4), and a grinding mechanism and a second driving mechanism both disposed in the housing (4). Both the first driving mechanism and the second driving mechanism are in transmission connection with the grinding mechanism. In the coal grinding device for a thermal power system of a power plant, a curved surface is disposed on one side of each auxiliary grinding plate (22) close to each first grinding roller (19), so that the grinding area of the first grinding rollers (19) and the auxiliary grinding plates (22) can be greatly increased, thereby improving the grinding efficiency of the device. In addition, a plurality of second grinding rollers (21) is disposed at the bottom of each first grinding roller (19), so that grinding is carried between the second grinding rollers (21) and the grinding discs, so as to fully grind coal briquettes, thereby improving the grinding reliability.
