Problems solved by technology

However, the high pressure and the inhomogeneity of the crushed material will cause the movable roller to retreat at a large acceleration, resulting in a very large impact load, causing strong horizontal vibration and torsional vibration of the main shaft
Therefore, compared with ordinary roller press mills, the problems involved in high-pressure roller mills are much more complicated, whether it is the structure of the machine, transmission components, or mechanical properties.
[0003] In the prior art, the high-pressure counter-roll mill adopts hydraulic loading to realize the high pressure between the two rollers of the counter-roll mill. Although the structure is compact, the response speed cannot keep up with
The material of high-pressure roller grinding is inevitably uneven. If the roller cannot change the gap and stabilize the pressure between the rollers by moving forward and backward according to the change of the uniformity of the feeding within milliseconds, then the machine will frequently Overload, frequent failure or even early damage; and the hydraulic loading device has irreversible system damping, and the time required from sending a letter to the action of the cylinder is less than milliseconds

Abstract

The invention discloses a gravity loading type high pressure double-roller extrusion mill, comprising a mainframe rack provided with an extrusion mill working cavity, and a fixed shaft rotating roller and a movable shaft rotating roller arranged in the extrusion mill working cavity, and a pressurizing device movably arranged on the mainframe rack, wherein the pressurizing device applies an extrusion force to the fixed shaft rotating roller and the movable shaft rotating roller by controlling the position of the movable shaft rotating roller. The gravity loading type high pressure double-roller extrusion mill is characterized by further comprising a gravity loading mechanism acting on the pressurizing device, wherein the gravity loading mechanism comprises a heavy loading block, and the gravity of the heavy loading block is converted into the pressure between the fixed shaft rotating roller and the movable shaft rotating roller by the pressurizing device. The problem of large impact load caused by delayed response speeds of hydraulic loading and roller retreat is overcome in the prior art, horizontal vibration and torsional vibration of the main shaft are avoided and the working reliability of the whole machine is greatly improved.

Description

technical field [0001] The invention relates to a gravity-loaded high-pressure double-roll extrusion mill, which belongs to the technical field of high-pressure crushing equipment. Background technique [0002] The high-pressure double-roll mill increases the pressure between the two rollers of the common double-roll mill from less than 10Mpa to 50-300MPa. It can instantly roll the material into a powder cake and apply a slight external force. Pressed powder becomes powder. Because the material passes through the working space of the roller press wheel very smoothly, without impact, and the noise is very low, so the crushing efficiency of the high-pressure roller press mill is very high. However, the high pressure and the inhomogeneity of the crushed material will cause the movable roller to retreat at a large acceleration, resulting in a very large impact load, causing strong horizontal vibration and torsional vibration of the main shaft. Therefore, compared with ordinary...
