Seam presser / finger presser / seam creaser The separation of areas on the surface of the groove also allows one to eliminate the stress that occurs at the place of separation of the briquettes. Because of the dimensions of the elements, which are larger than the gap between the rollers, the stress values obtained in these areas cannot be considered reliable.

Steam is also helpful for pressing seams perfectly flat, especially when paired with a clapper. The clapper will soak up the excess moisture and leave you with perfect seams.

The dependence of the press drive power on the moisture content of the material and the circumferential speed of the rollers when briquetting calcium hydroxide [ 55]. Uses: Pressing delicate fabrics, avoiding scorch marks on wool and linen, avoiding heat damage on fabrics that can’t take high temperatures. Step 1: Lay the fabric wrong side up, so that you’re looking at the stitching of the dart. Press the dart to form a crease along the central line of the dart, and to set the stitching into the fabric. Chung, W.-H., et al. (2018).

[ Google Scholar] [ CrossRef] The finite element method (FEM) is quite well developed and widespread in various fields of mechanics [ 31, 32]. This method has some ability to model in detail the compaction of fine-grained material in the rollers and, as a result, improves the optimisation of the technological process and equipment. It looks pretty attractive because it allows one to study the behaviour of fine-fraction materials and tribological conditions. However, there is a problem that this method is currently not sufficiently programmatically and theoretically developed for the study of multicomponent mixtures. That applies to fine-grained mixtures in which various components, fractions, and binders are present, including those containing a liquid phase. The results of calculations using the finite element method largely depend on the specific experimental data to determine, which requires quite expensive specialised equipment. There are studies on the application of this method to studying the parameters of briquetting, which investigated the effect of the configuration of the forming elements on the energy parameters of the process and the stress distribution in the compacted material [ 33, 34, 35, 36]; however, in the authors’ opinion, too much simplification was used in the presented works, e.g., rollers roll material spread out on a flat surface. FLSmidth is a world leader in roller press technology having supplied several machines over the last 30 years. Our roller press family is split into two product lines, each uniquely designed to best serve their respective industry:Giusti, G., et al. (2014).
