Ignoring mechanical losses in this drive train, the power transmission at each stage, defined as torque x speed, is constant. The typical mechanical inching drive motor speed is around 1500 to 1800 RPM while the mill inching speed is in the order of to RPM. Thus, the gear reduction ratio between the inching drive motor and the mill is ...
Ball mills designed for long life and minimum maintenance Metso overflow ball mill sizes range from 5 ft. x 8 ft. with 75 HP to 30' x 41' . and as much as 30,000 HP. Larger ball mills are available with dual pinion or ring motor drives. Our mills incorporate many of the qualities which have made the Marcy name famous since 1913.
The sample collected (Blend A) in the mill feed was sized and BWI tested (rod/ball), representing the base case. The size distribution curves for each blend Figure (feed) are shown in 1 while the F 80 and BWI (rod/ball) test results are shown in Table 2. The slurry sample collected from the mill discharge had a P 80 of 280 μm (downstream target
1/3. Operation. The Metso Polymer HSB system ensures optimal performance of your grinding mill. The system improves the durability and serviceability of both radial and axial hydrostatic bearing pads compared to bronze or whitemetal pad bearing systems, thereby eliminating unplanned shutdowns due to bearing failure.
Metso offers three standardized inspections for your grinding mill so that you can catch problems early: Mill visuals and vitals: Aimed at improving mill reliability, this inspection focuses on catching cracks, oil contamination, and slurry leaks with minimal downtime. Mill mechanical verification: Aimed at improving mill integrity, this ...
The Polymer HSB system's stateoftheart selfaligning capability ensures that the pads are always precisely aligned with the mill journal. This facilitates bestinclass load measurement using bearing pressure and ensures bearing loads are evenly distributed across the mill journal. The selfaligning capability is achieved through detailed ...
Vertimill® has 50% less footprint than a ball mill. Lower operating cost Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 10 microns. This provides up to a 40% higher energy efficiency.
Metso developed Horizontal Mill Plant Units to support grinding circuit selection, as well as circuit implementation. Our preengineered modules provide a unique edge in delivering rapid, safe and optimal solutions for many grinding applications.
3. Mill head 4. Trunnion liner 5. Bearing liner The best a ball mill can get FLSmidth has installed almost 4000 ball mills at locations worldwide which has given us a unique insight into the stresses and strains arising out of ball mill operations. The large alternating stresses placed on ball mill trunnions and heads are a great example.
Additional inspections, measurements and services performed including: Gear wash. Gear and pinion inspection. Core sampling survey. UT inspection of flanges and wall thicknesses. Metso engineers present retrofit designs and procedures, if required. Performed in 1 shift with mill running and 68 shifts with mill stopped.
Particles are first fed through a grinding stage which can use any combination of an HPGR, ball mill or rod mill. The particles are then fed through a desliming hydrocyclone and a screen before being fed either back in to the grinding stage or towards the beneficiation stage. Metso offers the following products for this process stage:
50% less footprint vs ball mill (In same application) < 2 weeks to install Up to 40% higher energy efficiency 95% or greater uptime A versatile and energy efficient solution Metso Vertimill® is the industry benchmark in gravity induced milling technology. Globally recognised as efficient grinding machines, they bring substantial

Suitable for pebble mills (magnetic ore), light duty ball mills and Vertimills™. Orebed is a mill liner with totally unique properties. If you have a Vertimill or a pebble mill with magnetic ore, Orebed is the superior solution for you offered only by Metso. Selecting Orebed, you can count on a longlasting liner that needs no maintenance.
Therefore, the need to make full use of these machines and their installed power is critical, so that this energy is effectively utilised. Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and ...
