LARGE INDUSTRIAL DRUMS
Whether for bulk conveying in the mining and quarrying sectors, or for installations requiring high throughput, ALTEMA manufactures conveyor drums up to 1,300mm in diameter. ALTEMA regularly manufactures drums for customers worldwide with diameters of Ø609mm, Ø813mm, Ø1016mm and Ø1250mm.
Manufacturing a large conveyor drum requires a different approach. Compared to conventional drums, handling phases have to be anticipated, as well as specific assembly tools. ALTEMA is equipped with large lathes for machining drums up to 1300mm in diameter and 6 meters in length. The workshops are also equipped with heavy-duty overhead cranes for handling these large drums. ALTEMA can machine shafts up to a diameter of 300mm inside the drum, turned down to Ø260mm at the bearing.
The manufacture of large industrial drums also requires special expertise in the assembly of large SN and plummer block bearings. ALTEMA has the tools and know-how to apply coatings to these large drums using manual gluing.

Laggings for large-diameter drums
ALTEMA can equip large conveyor drums with any type of lagging. Each application requires its own type of lagging. ALTEMA’s teams can help you define the type of lagging and the process that will best enable the drum to perform its function.
LINKING SYSTEMS for conveyor drums
ALTEMA conveyor drums can be fitted with various types of shaft/flange connections, such as Vecobloc hubs, shrink discs, bearings…
CLAMPING RINGS
The shrink disc system works by radially deforming frustoconical parts. This radial deformation creates a clamping force that prevents axial movement.
VECOBLOC UNIVERSAL HUBS
ALTEMA offers VECOBLOC removable hubs. This system is used to secure the flange + tube assembly of the “industrial drum” to its shaft without the need for special tools. ALTEMA offers a wide range of removable hubs to meet all requirements. This solution offers users an alternative to clamping brackets.
