Premier Roll Compaction Technology
Upgrading and converting undesirable dust fines
Ludman compactors’ roller style press combines torque, via roll drive system, and thrust, via cylinders in a stressed frame to agglomerate fines. Moreover, agglomeration involves a chemical process, in which two counter-rotating rolls press granular material into larger pieces. Reduction in surface area of agglomerated material leads to better product, and thus, explains why coarser feed is most desirable. In other words, large particles retain less surface area, resulting in less work per unit volume.
Salable granular product
Ludman press-forged rolls, pre-stressed robust frames, tie rods, super bolts, gearing options are all designed to benefit customer environment. To illustrate, other features include inline planetary reducers, hydraulic motors and dual output gearboxes, heavy duty mining grade motors, advanced positioning electrical control systems coordinated motion force feeders, and over one hundred years history in the agglomeration and size reduction machines.
Additionally, Ludman roll compactors process a tremendous number of application-specific requirements. Our compactors provide unique, custom solutions for each customer, such as choosing between force or gravity feed, fine or coarse feed, hot or cold feed, and high throughput versus low throughput. Likewise, Ludman roll compactor technology seamlessly pulls or pushes fine material into the nip zone of a dual roll press. Rolls pull material through the roll nip, and produces dense output.
Vast experience in potash and salt applications
Ludman Industries is a world leader in roll compaction of potash fines—both floated and crystalline fines—with over one hundred machines installed worldwide.
In particular, Ludman has over fifty-three years of experience compacting white crystalline potash with installations at Mosaic Belle Plaine and Nutrien Cory mines in Canada; and at Intrepid and Cargill facilities in the United States of America; as well as SQM in Chile.
Specializing in fines management applications
Ludman Roll Compactors specialize in fines management applications. Products that are separated as fines, produced as a fine grain, or contain highly friable characteristics generate plenty of dust. However, Ludman specializes in upgrading or converting undesirable dust fines into salable granular product, through compaction. Many fertilizer producers tussle with undesirable fines. However, Ludman Machines solve this issue by producing dense material that is easily shipped, distributed, and spread on farmers’ fields across the world.
