The pulp lifter is an integral component of autogenous (AG) and semi-autogenous (SAG) grinding mills as it controls the throughput, performance and efficiency of mills. The slurry transport from the AG/SAG mill through grate holes into the discharge trunnion is the main function of the pulp lifter.
The Masbate gold deposits are situated on the island of Masbate, 350 km south of Manila. A new plant was commissioned in April 2009. The grinding circuit consists of one semi-autogenous (SAG) mill 9.75 m 4.27 m, two ball mills 5.6 m 7.1 m and a pebble crushing circuit, which is usually called a SAG-ball mill-crusher configuration. The SAG mill was originally equipped with radial pulp lifters.
Curved Pulp Lifters Can They Save Energy. Observations carried on after installation of the curved pulp lifters have confirmed, as expected, a reduction in wear intensity on the outer pulp lifters. in addition to this, at early stages of operation with curved pulp lifters, the mill operator noticed a reduction in energy consumed by the mill with no detrimental effect on mill ...
Performance characteristics of mill pulp lifters 1235 Unfortunately, there are no published data either to substantiate these claims or to understand what relationship exists between the performance of pulp lifters and mill operation. Given this lack of published data, a research programme was initiated in this area at the JKMRC in 1992 to ...
discharge mill liners in a specific condition: wear resistant rubber and steel frame body creates combination, which is especially good in circumstances where • pulp lifters must endure high pulp flow and abrasive wear from grinded mineral. All Teknikum® Pulp Discharging System liner components are moulded or rubber coated and tailor made ...
Curved pulp lifters have been incorporated in SAG and AG mills in Australia. The aims have been to ensure complete discharge, at high throughput, of both slurry and coarse solids, especially at high mill rotational speeds. Curved pulp lifters can overcome incomplete discharge and back-flow of solids down the pulp lifter that can occur in ...
The backflow of non-discharged rocks can limit the pulp-lifting performance and add to wear at the base of the pulp lifters. Adequate front-to-back depth in pulp lifters is necessary to ensure good pulp-lifting performance, with some SAG-mill operators having adopted curved pulp lifters, especially of the 'hockey stick' shape.
The Open-Ended Discharge Grinding Mill (OED Mill) enables innovative and efficient high-capacity circuit designs through the removal of pulp lifters from the discharge arrangement, facilitating reductions in both CAPEX and OPEX. Instead of …
Overtopping within the pulp lifter, by means of a perfect, geometric spiral improving the wear life of the pulp lifter, clearly visible on the rear side of the lifters and centre discharger Flow-back in the centre discharger triggered by altering the trajectory within …
A pulp lifter and a pulp lifter assembly are described for a rotary grinding mill. The pulp lifter has a leading edge and a trailing edge with respect to rotation of the mill, and includes a first wall bounding an interior space and a second wall dividing the interior space into first and second regions.
At Cortez Gold Operations the shell and pulp lifters of the semiautogenous grinding mill was redesigned. The redesigned shell lifter has been in operation for over three years and the redesigned pulp lifter has been in operation for over nine months now. This report summarizes the dramatic reductions in energy consumption.
Curved pulp lifters have been incorporated in SAG and AG mills in Australia. The aims have been to ensure complete discharge, at high throughput, of both slurry …
A Laboratory Study Of The Performance Characteristics Of Mill Pulp Lifters Predicting The Specific Energy Of Autogenous And Semi-Autogenous Mills From Small Diameter Drill Core Samples A Method For Predicting The Specific Energy Requirement Of Comminution Circuits And Assessing Their Energy Utilisation Efficiency
Request PDF | Performance characterisation of AG/SAG mill pulp lifters using CFD techniques | The pulp lifter is an integral component of autogenous (AG) and semi-autogenous (SAG) grinding mills ...
The pulp discharge mechanism, consisting of a grate and pulp lifter arrangement, is an integral component of these mills. The grate retains over-size particles in the mill charge. The pulp lifters transport the slurry, which has passed through grate holes, into the discharge trunnion.
pebbles pass through the grate into the pulp lifters, the motion or flow behavior of solids will be different to the slurry. The DEM simulation of pebbles flow in pulp lifters in 36-ft diameter SAG mill is shown in Figure 5. At the end of one revolution, all the pebbles are …
In addition to this, at early stages of operation with curved pulp lifters, the mill operator noticed a reduction in energy consumed by the mill with no detrimental effect on mill performance. This paper is intended to further study the effect of curved pulp lifters on mill energy consumption. Ciutina, S and Soriano, R J, 2014.
The mill pulp lifter processed more than 28 million tons while improving slurry throughput by 6%. Our customer reached break-even at half of the parts' lifetime and a throughput benefit to the order of seven digits USD in 12 months. Fabricated materials weigh less than cast steel, and in some cases, FL has been able to reduce total ...
