Conditions for re-drawing on complete sets of corn processing machinery

发布时间：2023-12-29 点击次数：

Sets of corn processing machinery in many accessories are fragile, especially the milling machine in the milling roller, after using a period of time, the need to re-drawing of the milling roller, many people do not quite understand what the role of drawing, today we will explain to you:

　　Roller drawing is an important work to improve the grinding effect of complete sets of corn processing machinery, if the poor drawing will make the drum skin shredding mixed into the flour, and power consumption, yield, flour rate have an impact. Therefore, we must pay attention to the quality of drawing, improve the drawing technology, to ensure that the process requirements.

　　(1) grinding rollers must be polished before drawing, because the grinding roller is a cylinder, can not appear head big, head small phenomenon. Complete sets of corn processing machinery grinding roller in operation can not produce radial runout, to ensure its concentricity and ellipticity.

　　(2) The surface of the grinding roller can not be concave and convex, grinding teeth should be no burr, no fracture and middle collapse phenomenon.

　　(3) Do a good job of grinding knife. Grinding shall be mastered by the technician with grinding technology to ensure that the grinding teeth are uniformly coarse and fine, and the grinding teeth shall not be pulled through, resulting in wrong silk and silk phenomenon.

　　(4) grinding teeth should be required to leave a fixed tooth plane, pull the tip of the knife to leave a fixed degree of isolation.

　　(5) when pulling the roller, wire drawing machine in the complete sets of corn processing machinery work shall not have jumping and fast and slow phenomenon. Drawing machine oil pump, gear wear should be timely maintenance.

　　(6) Pulling the grinding teeth, angle, slope, number of teeth shall comply with the technical requirements of the process.
