Formal structure, there are two grinding mill, two structures have their own characteristics: one is the cover with a hollow shaft integral cast, this structure is simple, relatively easy to install, suitable for small and medium sized ball. For larger diameter mill, easy to produce casting defects, even with more Riser casting, cooling contraction is not uniform, so that the transition surface of the hollow shaft and cover a greater stress and loose, Sometimes this defect in the closet, not to discover a small dressing mill price, due to the site at the time of mill operation, bear alternating stress and a greater stress concentration, resulting in breakage during operation after a period of time, then causing The loss is even greater; the other is to cover and grinding hollow shaft and then divided into two parts together, the end caps and hollow shafts are casting, processing assembly together with bolts, this structure avoids the above casting defects. Although this can solve some problems, but more than the consumption of raw materials and processing workload, and increased installation work; cover with steel plate welded structure, its advantage is mechanical manufacturing process is simple beneficiation mill, cutting programs and cutting less machined surface, less consumption of raw materials, cover quality is guaranteed, there is no casting casting defects. Cover and cylinder welded together, connect securely labor beneficiation mill much money, avoid the higher requirements bolt or rivet connections. Such hollow shaft is only the opening round of castings and cover bolted into the grinding position overall. Currently mill load detection method include: Univariate sound method, current method, useful power method, vibration method, the pressure sensor method, differential electromagnetic sensor method, Hall power transmitter law, tracer method assay; power - double sound signal detection, noise - double vibration signal detection, power - dual vibration signal detection of two-factor assay and detection methods is moving more in the direction of joint detection factors.
