MGS GEARS

Founded in 1964, the Laterlite Group is an Italian multinational leader developing lightweight and insulating solutions for building, construction, civil engineering, geotechnical engineering, industry, and the environment. To this end, it has four production plants for lightweight and insulating aggregates, special concretes and mortars, and lightweight insulating blocks, which it manufactures through Lecasistemi, which is part of the group.

In one of the company’s plants located in the outskirts of Parma (Italy), the production team noticed anomalies in operating a rotary clay dryer mill that had been working uninterruptedly for many years. Laterlite contacted MGS Gears, and, after an initial inspection, we detected problems in the entire transmission system due to significant wear of its components: gearbox, pinion, and In addition, it warned of a significant risk of failure in the short term, in an estimated period of 3 to 4 months, which could force the interruption of the plant’s production.

To solve these problems and ensure equipment and production reliability, MGS Gears recommended upgrading and improving all transmission components. We manufactured a new gearbox with an increased service factor over the original, a new pinion and a new girth gear with upgraded materials, and an increased service factor (with hardness characteristics exceeding 280 Brinell for the pinion and 250 Brinell for the girth gear.) As of the date of publication of this note, and as seen in the photographs, we have been manufacturing work has been completed. The best time to proceed with the installation is already being studied and planned with the customer.

Rotary dryers are a very effective industrial drying option for bulk solids. They are often chosen for their robust processing capacity and versatility to operate optimally regardless of the raw material.

Rotary dryers operate by spinning the material in a rotating drum while conveying a drying air stream. Depending on the model, they can also be indirectly heated to avoid direct contact with the material.

The drum is placed on a slight horizontal slope to allow gravity to help move the material through the drum. As the drum rotates, lifting vanes pick up the material and drop it through the air stream to make heat transfer more efficient and consequently drying. When working with agglomerates, the rotation also allows, as an added benefit, further smoothing and polishing of the granules.

For over 20 years, we have been offering products and engineering solutions for all types of industrial applications drives such as Ball Mills, Rotary Dryer Furnaces, Bucket Elevators, using gearboxes and components capable of adapting to any assembly requirement, space availability, and required torque and ratio, etc. We count on a wide range of special bearings and power transmission solutions for the CEMENT industry to help optimize your production processes and extend the life of your industrial equipment.”
