Embodiment Construction

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

[0011] A new type of vertical roller mill, including a rotating shaft 1, a hydraulic cylinder 2, a rocker arm 3, a bearing seat 4, a grinding roller 5, and a column 6; The grinding rollers 5 are connected, and the hydraulic cylinder 2 presses the rocker arm 3 to make the grinding roller 5 rotate along the rotating shaft 1 as a lever, and the torque is transmitted through the rocking arm 3 to pressurize the grinding roller 5; the rotating shaft 1 passes through the middle of the rocking arm 3, and the rotating shaft 1 Bearing blocks 4 are sleeved at the two ends of the two ends, and the bearing blocks 4 are fixed on the column 6 upper surface. The centerline of the rotating shaft 1 is parallel to the axial centerline of the grinding roller 5 .

[0012] Adopting a new pressurization method and a column form saves the steel consumption of the mill body, reduces...

Abstract

The invention discloses a novel vertical roller mill which comprises a rotary shaft, a hydraulic cylinder, a rocker arm, a bearing pedestal, a grinding roller and a vertical column, wherein the hydraulic cylinder is externally arranged at the lateral side of the grinding roller and is connected with the grinding roller via the rocker arm, the rocker arm on the hydraulic cylinder drives the grinding roller to do the lever rotation along the rotary shaft, and the grinding roller is pressurized via the carry-over moment of the rocker arm; and the rotary shaft penetrates through the middle part of the rocker arm, bearing pedestals are sleeved on two ends of the rotary shaft, and the bearing pedestals are fixed on the upper surface of the vertical column. The centre line of the rotary shaft and the axial center line of the grinding roller are parallel. The novel vertical roller mill disclosed by the invention adopts a pressurizing method and a vertical column mode, so that the use quantity of steels of a main body of a grinder is saved, the height of the grinder is reduced, and the space occupation is reduced; and at the same time, the installation and the overhaul of the grinder are convenient. The novel vertical roller mill has the advantages of being reasonable in stress, reliable in operation and convenient to detach.

Description

technical field [0001] The invention relates to the field of construction machinery equipment, in particular to a vertical roller mill. 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 vertical roller mill, which adopts a new pressurization method and a column form, which saves the steel consumption of the mill body, reduces the height of the mill, and reduces the floor space of the mill. It facilitates the installation and maintenance of the mill. [0004] In order to achieve the above object, the present invention adopts the following technical solution...
