Start with published model records to identify twin-screw agitators, wear blocks, magnetic shell liners, bottom liners and pipe linings, then shafts, gearboxes, bearings, seals, materials and drawing for quotation.
FTM is a low-speed vertical tower mill using steel grinding media. Its central twin-screw agitator is the only moving component in the grinding chamber. This page uses only published FTM, FTM-1500 and FTM-5000 records; unpublished dimensions or power ratings are not inferred from model numbers.
Only particle sizes, installation counts and project details explicitly published in current FLS data sheets and official announcements are listed. Unpublished dimensions, power and speed are not inferred.
| Series / Model | Record Type | Published Particle Sizes / Dimensions | Published Applications and Design | Spare-Part Verification Requirements |
|---|---|---|---|---|
| FLS Tower Mill (FTM) | Current Product Series | F80 up to 3 mm; P80 20 μm or finer | Secondary and tertiary wet fine grinding; central twin-screw agitator, steel media, bottom feed and top discharge | Confirm dimensions, power, speed and media charge against the project selection documents. |
| FTM-1500 | Installation Record in the Official Data Sheet | F80 74 μm; P80 21 μm | 7 mills recorded at the Benxi Mining magnetite concentrator in China | Model and particle-size data come from the 2024 official FLS data sheet. Confirm parts by the individual machine's serial number and drawings. |
| FTM-5000 | Official Order Record | Overall dimensions and power were not published in the official announcement. | 18 mills for an Indian iron-ore project, for secondary and tertiary grinding, with installation and commissioning planned for 2026/2027 | Only published model and project details are used. Power or dimensions are not inferred from “5000”. |
The numbers on the diagram correspond one to one with the rows below.

Start with the FTM-specific twin-screw agitator and high-wear tips, then review the shell, bottom, feed and discharge areas. Each item links to the corresponding component and material pages.
Double-helix Agitator Screw
The only moving assembly in the FTM that directly contacts slurry and steel media. Verify the full model, screw outside diameter, pitch, overall length, hand, sectional design, main-shaft interface, wear-block layout, dynamic balance and lifting points.
View the Component Page →
Screw Tip / Flight Wear Segment
Located on screw-flight edges and high-wear areas, these are priority replacement parts during media agitation. Verify level, left or right hand, inner or outer position, profile, thickness, hole pattern, counterbores, orientation and gaps between adjacent blocks.
View the Component Page →
Shell Magnetic Liner System
Protects the vertical chamber and uses magnetic retention to form a stable lining. Verify the FTM model, shell zones, number of rows, panel dimensions, curvature, magnetic retention design, door area and feed/discharge connections.
View the Component Page →
Bottom Plate / Base Liner
Protect the chamber bottom and the area around the bottom feed. Check segmentation, centre hole, feed opening, plate thickness, hole pattern, curvature, lower screw clearance, drain connection and dismantling sequence.
View the Component Page →
Feed Pipe / Chute Liner
FTM is bottom-fed, exposing feed pipes and bends to erosion by high-solids slurry. Check pipe diameter, bend radius, flanges, flow direction, lining thickness, end seals, supports and chamber connections.
View the Component Page →
Discharge Pipe / Overflow Liner
Protect the upper fine-product discharge and flow-turning areas. Check outlet, pipe diameter, bends, flanges, lining thickness, flow direction, supports, overflow elevation and downstream connections.
View the Component Page →Low-speed, high-torque vertical drives have specific requirements for alignment, rotation, journal accuracy, bearing loads, lubrication and condition monitoring. Parts cannot be identified merely as generic tower-mill spares.
Agitator Main Shaft
Connects the upper drive to the twin-screw agitator and transmits high torque. Check overall length, shaft diameters, flanges, keys/splines, bearing seats, coupling, screw connection, rotation, runout and lifting interfaces.
View the Component Page →Gearbox and Drive Assembly
Delivers power to the low-speed, high-torque agitator shaft. Check the FTM model, drive arrangement, rated power, input/output speeds, ratio, output shaft, coupling, mounting flange, lubrication and monitoring connections.
View the Component Page →
Bearing and Seal System
Supports the vertical shaft and isolates the lubricated area. Check bearing designation, clearance, thrust/radial loads, shaft/housing fits, seal type, lubrication, cooling, speed and monitoring points.
View the Component Page →
Bearing Sleeve / Bushing
Provide fits and replaceable protection at bearing, support or connecting positions. Check assembly level, inside/outside diameters, length, flanges, oil grooves, interference, retention and mating shaft/housing materials.
View the Component Page →Model names alone do not establish interchangeability. Agitators, main shafts, shell liners, drives and piping must be checked against the full model, serial number, OEM drawing revision and installation dimensions.
No. FTM is a low-speed tower mill with steel media and a central twin-screw agitator. VXPmill is a higher-speed stirred mill with ceramic media, removable discs and spacers.
