Abstract

The invention relates to the technical field of grinding devices, and discloses a double-grinding-barrel grinding device which comprises two grinding barrels, end covers and grinding rollers, the grinding rollers are installed in the grinding barrels, a driving device is arranged below the grinding barrels and drives the grinding barrels to rotate, the end covers are rotationally connected with the two ends of the grinding barrels, and the end covers are rotationally connected with the two ends of the grinding barrels. A pressing rod is arranged at the rear end of the grinding roller, a hydraulic rod is connected to the bottom of the pressing rod, a long hole is formed in the rear end of the grinding barrel, rotating columns are fixedly connected to the two ends of the grinding roller, and the rotating columns are movably connected with the long hole in the rear end of the grinding barrel. By arranging the two grinding barrels, the two grinding rollers and the driving device, when the motor, the chain and the gear drive the grinding barrels to rotate, the grinding rollers are kept static in the grinding barrels, and the grinding rollers can descend, when the grinding barrels rotate, the grinding barrels and the outer walls of the grinding rollers can be mutually extruded, the ore grinding effect is achieved, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of grinding devices, in particular to a grinding device with double grinding cylinders. Background technique [0002] High-pressure suspension roller mill (also known as super-pressure mill) is suitable for grinding various ore and chemical raw materials and other non-metallic raw materials, such as: iron ore, coal powder, blast furnace slag , power plant desulfurizer, boiler injection coal, lime, feldspar, quartz, gypsum, barite, limestone, ceramics, slag and other non-flammable and explosive mines with a Mohs hardness not greater than 9.3 and a humidity below 6% High-fine powder processing of more than 280 kinds of materials in industries such as metallurgy, chemical industry, building materials, etc., and the particle size of the finished product can be adjusted in the range of 80-425 mesh (the finest 1000 mesh). The high-pressure medium-speed mill can produce 30-80 mesh coarse powder by adding special d...
