tube mill body structure, cylinder and end caps join type
Yufeng Heavy Industry is a professional manufacturer of ball mill manufacturers in the production of the plant when the mill shell, using the internal flange coupling structure design.So Yufeng professionals are here to talk about the structural design of Ball Mill: First, the structure of the general form of the cylinder barrel are designed to the overall structure, because the overall structure of the manufacturing composite variation is relatively small, and the processing costs are relatively also lower.Large size of the cylinder is often affected by transport conditions and the manufacturing and processing capacity constraints, and design elements had to be tube-stage; structure.Barrel sections between sections commonly used with positioning spigot flange connection structure.Cylinder segmented Another method is field welding: Cylinder in the factory segmented by transport conditions, and then accurately machined with a special spigot weld groove, together with a full set of special welding equipment fainting scene, by the manufacturer of welding and welders in the field to eliminate welding stress.This method is only a few units in the region need to shell mill site welding is rather advantageous, otherwise it is not economical.Second, the form of the cylinder and the cylinder cover and the coupling link grinding cover the following three forms: a.External flange coupled to the large-scale mill before specification, the cylinder using an external flange connected to the end cap structure is widely used, which is characterized by the grinding assembly more convenient, but the diameter of the cylinder shape, and the machinability surface and material consumption is relatively large.b.Internal Internal flange type flange coupling is widely used in medium-sized mill body structure.Which is characterized by a very high utilization of raw materials, structural design is reasonable.c.Lan Lan connection can not actually connected to the cylinder and grinding cover soldered directly into one of the structure, welded joints are butt-welded construction.Structural trends from the end cap of view, this can not be linked in the form of blue butt welding, will be in a variety of sizes and types of mill body, because it has a reasonable structure, easy to manufacture and use and reliable features. "Ball Mill of the structure, the cylinder end cap type of join in the "traditional form of a feed mill classification
Impact mill grinding efficiency is one of the Ball Mill factors to the mining speed, and to mine the speed is determined by the ball mill feeders decision.Ball mill ball mill feed device for feeding is a complete system, less traditional forms of feed mill there, what does?Yufeng professionals believe that there are three: Why lime mill difficulty in starting
There are a lot of users in the use of lime mill, that they will encounter such a problem is Lime mill sometimes difficult start, which is what causes it?Encounter such problems do not worry, we should first find out the reasons remedy, so as to solve the problem faster.So here today, Henan, give often we talk about what are the reasons for this problem: one of the reasons: Forged steel ball or excessive loading, the startup will become difficult because of the two: Lime mill motor power less than the rated power, there will be a difficult start feeling sleepy high.
