3 reasons of the wear of the ball mill liner. Firstly, the wrong installation method will lead to insufficient concentration of the lining plate, which leads to rupture; Secondly, the raw material ...
Force analysis. The main function of the ball mill liner is to protect the mill and use the convex peak of the liner to play the ball to grind and crush the material. Therefore, the main failure mode of the liner is abrasive wear under the repeated impact of small energy. Fig. 1 shows the motion diagram of grinding ball and material.

The automatic grading ball mill liners enable the larger steel balls in the barrel to be concentrated at the feed end to crush larger materials, while the smaller steel balls are concentrated at the discharge end to crush smaller materials. The Selection and Classification Design of Mill Liners
Mill Liner Profiler Tool Track Liner Wear Pattern. Here is a homemade tool to measure or obtain a fingerprint of your SAG and Ball Mill Liner wear pattern/profile. Each time you shut down, get a profile and build a wearlife over time database to better predict your next reline job or monitor improvements to your liner design.
reduce packing and ball/liner damage, and to use larger, hence fewer, mill liner parts to reduce downtime at liner changeouts. Key words: Comminution, Grinding, SAG mill, Mill liners Paper number MMP07002. Original manuscript submitted online January 2007. Revised manuscript accepted for publication April 2007.
Ball mills are the foremost equipment used for grinding in the mineral processing sector. Lifters are placed on the internal walls of the mill and are designed to lift the grinding media (balls ...
Abstract. To understand the friction and wear of working mediums in iron ore ball mills, experiments were conducted using the ball cratering method under dry and wet milling conditions, which ...
The specifications this above ( F100= 2000 mm and 472 KW power in Pinion for a word index of it is just the contractual data of ball mill supplier. At present the secondary cruscher is F100=12mm and work index will be the order of 15 kWh/T according to this above data. Diameter ball mill= the length is m. thanks lot for your help
Application of the proposed method in a × m SAG mill indicated that the liner wear profile along the liner length was nonuniform and the highest wear occurred between m and m ...
Based on experience, millliner designs have moved toward more openshell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebblecrushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of :1 and :1.
Due to its strong lifting capacity and excellent grinding performance, the trapezoidal liner is widely used in the SAG mill. The structure of the trapezoidal liner is shown in Fig. 1, the main dimensions are: dip angle (tau), length of the top edge (L) and height (h).Dip angle (tau) determines the trajectory of the mediums in the SAG mill, which directly affects the impact speed and ...
Mill SHELL Liner HEAD Liners. Grate discharge heads for ball mills are completely assembled in the shop, with grates, clamp bars, pan liners, and center discharge liners in place. Depending upon available handling facilities, the head or shell can be lined separately in a repair bay, or after assembly of the mill proper in the trunnion bearings.
Specifications. When installed, the magnetic liners are directly attached onto the inner wall of ball mill with no bolts. When the ball mill operates, the magnetic . Ball Mill Specifications. BALL MILL Make : Dominion Goninan . Withour shell liner, feed and inner and outer liners, with feed spout, discharge
Ball Mill Model The main structure of the ball mill is composed of three parts, namely the feed inlet, the cylinder part (work bin), and the discharge port. Figure 2(a) shows the structural model of a ball mill. In the mill cylinder part, there are lifters for turning over the particles. The quartz sand particles enter the cylinder through a
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
Average kinetic energy of grinding body in ball mill with various liners (J) Wave liner Lifter Step liner Double wave liner The double wave liner and the liner with lifters are the most effective because the average kinetic energy of the balls is higher than other type of liners (wave liner and step liner). ...
In a nonreversible hammer mill with screen bars, shown in above figure, material is broken first by impact between hammers and breaker plates and then by a scrubbing action (shear and attrition) of material against screen bars. Attrition crushing is most useful in the following two circumstances. When material is friable or not too abrasive.

The ball mill, an intermediate and finegrinding device, is a tumbling drum with a 40% to 50% filling of balls. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.

spacing and height of lifter bars, and to minimize liner/lifter and ball damage by avoiding impact onto the mill shell. This paper presents a short review of mill liner design and its effects on mill performance. Firstly, considerations associated with liner design are briefly described. Then, the effects of mill liner design
