Problems solved by technology

There are several disadvantages in this design. First, the nut needs to be twisted several times in a row, which is time-consuming, low in efficiency, and labor-intensive; The nut is reheated after reheating; the third is that the manufacturing precision of the screw-type nail puller is high, the coaxiality of the middle part and the flatness of the upper and lower edges of the sleeve are high, and it is difficult to make it by hand on site, and it needs to be made by a processing workshop; the fourth is to use the sleeve to be able to To withstand the roller skin between the densely distributed roller nails, it is required to have a small diameter, small thickness, weak sleeve strength, and easy deformation; fifth, the fine screw-type nail puller is prone to rust, jamming, and failure, especially in conditions poor production site

Description

technical field [0001] The invention relates to the technical field of high pressure roller mill maintenance, in particular to a high pressure roller mill roller nail recoil type nail puller. Background technique [0002] The high-pressure roller mill is a new type of energy-saving crushing and grinding equipment. After the material is fed, the gap between the static and moving rollers is opened, and between the static and moving rollers moving in opposite directions, it is "broken" under the high pressure of the hydraulic mechanism. In order to improve the service life of the static and dynamic rollers of the high-pressure roller mill, cylindrical holes are generally equidistantly opened on the roller skin, and the bottom of the hole is a hemisphere. Protrude the roller skin by about 5-10mm, so that during operation, an accumulation of material can be formed between the roller nails to protect the roller skin, and the roller nails can be replaced regularly after wear.
