Hard to believe, but true - we guarantee that a little practice is all you need and you'll soon be ironing shirts in minutes! Differences in the stress distribution on the forming cavity surface and the groove are reduced to the maximum stress distribution on the briquette surface. For the forming cavity, the maximum values fall on the outer sections and take similar values along the entire height of the briquette. At this point, the very high-stress values coincide with the edge wear of the work roller surfaces seen in roller presses. On the other hand, on the groove surface, the maximum stresses for a given width fall on the axis of the briquette, and their maximum values occur only on its upper part. The stress distribution in the forming groove is much more uniform and has a smaller amplitude. For calcium hydroxide, the maximum stress amplitude on the groove surface is 30 MPa, and on the surface of the formed cavity, 45 MPa. For a mixture based on copper ore concentrate, the maximum amplitudes are 46 MPa and 59 MPa, respectively. Regardless, ECONOMY Range cutters are still manufactured by our skilled technicians. But by incorporating innovative new ideas, specifying the best value materials, removing some superfluous refinements and relaxing tolerances - ECONOMY Range Cutters provide class leading performance at a mid-range price.

Each ADVANCED Range cutter is individually crafted by one of our skilled technicians - not manufactured on a production line basis - as used by our cheaper competitors. It is this extra attention during the manufacturing process, which maintains our policy to produce the finest cutters available. Primarily for this requirement, engineers at ARROW CUTTERS have developed many pieces of unique equipment - to accurately bend, form and crop rules up to 100mm deep. With this roller press 580 there is no danger of unwanted shiny spots and even rows of buttons pose no problem for the soft, highly-elastic roller Essential to that reputation has been the manufacture of cutters with perfect joins, essential to eliminate snagging and tears. ARROW CUTTERS has an unsurpassed international reputation for manufacturing superb quality cutters for Roller Press use.

The fixed roller is supported directly on the press frame, while the so-called floating roller is supported in the frame by a hydro-pneumatic spring. The movement of the floating roller constitutes the basic principle of a roller press. The extent of the roller movement (roller gap) is a function of the pressing force generated by the hydraulic system in relation to the reaction forces exerted by the material being processed and the preset "zero-position" of the roller gap. The gap itself is controlled by means of the hydraulic supply unit depending on the requirements of the specific process.This design feature guarantees that all the feed material passes through the roller gap under the same process conditions, thus ensuring that the output quality of the productremains constant. Stresses distribution on the forming cavity surface during briquetting of calcium hydroxide for the circumferential speed of the rollers: ( A) 0.1 m/s, ( B) 0.15 m/s, ( C) 0.2 m/s, ( D) 0.3 m/s. Sheets and tablecloths are child's play, thanks to the larger ironing surface. The big collecting table means that everything stays smooth and practically folds itself! One of the modern and advanced methods of modelling and deformation processes research of fine-grained bulk materials is the discrete element method (DEM) [ 37, 38, 39, 40, 41, 42]. The DEM method is significantly different from the FEM method. In fine particle materials briquetting and compacting process in a roller press, FEM has been considered an efficient modelling tool. FEM modelling was adopted to simulate the roller briquetting compaction process with plane strain two-dimensional cases [ 19, 23, 32, 33, 34, 35, 36] and with three-dimensional models during the roller compaction processes [ 43, 44, 45, 46]. However, FEM has been limited to macro-modelling, where it is used for simulating the interaction between the rolls and briquetted material. The material, in this case, is treated as a continuum. DEM gives a look into the micro-mechanical interactions of the particles within the briquetted material. This modelling method can provide data on the motion of the particles within the briquetted (compacted) material, particle collision forces, energy loss spectra, and power consumption, which are the data important for improving roller presses efficiency and gaining more understanding of the briquetting process kinetics.

ARROW CUTTERS unique range of transparent cutters is designed to offer the operator a completely unrestricted view through the cutting tool. Our most recent tools now also incorporate methods to allow the product to be moved from one tool to another, whilst maintaining precise location. This allows for motif welding, bar welding and die-cutting all to be performed with absolute precision.Equipped with a powerful 2,200watt motor and continuous steam burst output of 30g/min, the R02036 Rotary Iron is designed to handle even the toughest of fabrics. The pressing plate pressure is adjustable, and the 91.5cm width rotary drum is perfect for bedding and larger items. The essential part of this work includes the analysis of the stress distribution in the forming elements, the material flow in the pressing region, the briquettes density determination, and the energy-power parameters of the briquetting process. Considering the limited number of discrete elements that can be used for simulation, separate models were prepared to study specific parameters to achieve the best results.
