At the Lihir Gold Mine, the plant was utilizing mill's bearing pressure to calculate load measurement for the SAG mill in HGO1. The use of SAG mill weight for process control is additionally complicated at Lihir by compromised and suddenly drifting load cell and bearing pressure measurements on two of the process plant's three SAG mills.
The CLP loadcell is used in various high capacity compression applications such as, hoppers and ball mill weighing, etc. Capacity Range: 100 to 200 ton Download Specifications [PDF] ULS The ULS (Stainless Steel) loadcell is used for applications where corrosion protection is needed.
A load cell (or loadcell) is a transducer which converts force into a measurable electrical output. Although there are many varieties of force sensors, strain gauge load cells are the most commonly used type. Except for certain laboratories where precision mechanical balances are still used, strain gauge load cells dominate the weighing industry.
Thru Hole Load Cell. Donut Load Cell (aka Thru Hole load Cell) is a variation of a low profile compression load cell and features a compact, smooth thru-hole inner diameter design for use in applications to measure compressive loads which require a rod to pass thru the sensor center.One of the primary uses of this sensor type is to measure bolt loading.
The complete ball mill is bedded on a steel or concrete frame designed to rest on a defined number of load cells. The load cells are integrated into a control unit and determine the total weight of mill, grinding media and product. The addition of feed can be controlled with such precision that the mill always operates at optimum load.
