Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0011] A new type of material grinding device, including a rotating shaft 1, a bearing seat 2, a rocker arm 3, a grinding roller 4, a hydraulic cylinder 5 and a column 6; the hydraulic cylinder 5 is placed outside the lower part of the rocker arm 3, and the grinding roller 4 is connected to the rocker arm 3 Close to the end of the hydraulic cylinder 5, the rocker arm 3 is tightened by the hydraulic cylinder 5 to make the grinding roller 4 rotate along the rotating shaft 1 as a lever, and the torque is transmitted through the rocker arm 3 to pressurize the grinding roller 4; the rotating shaft 1 passes through the rocker arm 3 On the other end, the two ends of the rotating shaft 1 are covered with bearing seats 2, and the bearing seats 2 are fixed on the upper surface of the column 6. The centerline of the rotating shaft 1 is parallel to the axial centerline o...

Abstract

The invention discloses a novel material grinding device comprising a shaft, bearing seats, a swing arm, a grinding roller, a hydraulic cylinder, and a column. The hydraulic cylinder is arranged outside and below the swing arm. The grinding roller is connected to the end of the swing arm close to the hydraulic cylinder. The hydraulic cylinder tensions the swing arm, such that the grinding roller performs lever rotation along the rotation shaft. The swing arm is used for transmitting torque, such that the grinding roller is pressurized. The rotation shaft penetrates another end of the swing arm. The bearing seats are sleeved on two ends of the rotation shaft, and are fixed on the upper surface of the column. The central line of the rotation shaft is parallel to an axial central line of the grinding roller. According to the invention, a novel pressurization manner and a column form are adopted, such that steel material consumption of the grinding machine body is saved, grinding machine height is reduced, grinding machine land occupation is reduced, and grinding machine assembly and maintenance are convenient. With the novel vertical grinding device, advantages such as reasonable stress, reliable operation, convenient disassembly, and the like are provided.

Description

technical field [0001] The invention relates to the field of vertical roller mills, in particular to a material grinding device. Background technique [0002] At present, many domestic vertical roller mills are vertical mills in the pressurized form similar to Loesche mills. The grinding rollers are pressurized by the hydraulic cylinder tensioning device placed inside the column, which occupies a large area and is heavy. The hydraulic cylinder installation The problem of inconvenient maintenance. Contents of the invention [0003] The purpose of the present invention is to propose a new type of material grinding device, which adopts a brand-new pressurization method and column form, which saves the amount of steel used in the mill body, reduces the height of the mill, and reduces the floor space of the mill. At the same time, it also facilitates the installation and maintenance of the mill. [0004] In order to achieve the above object, the present invention adopts the f...
