Finally, for those clients who require the service, we can also provide a die-cutting service for making samples or a limited production run. The connection between the circumferential speed of rotation of the rolls and the force parameters of the briquetting process was investigated. Graphical and analytical dependencies were established, which show the increase in rolling torque and energy consumption with increasing peripheral roll speed. It is noted that in the studied range (0.1÷0.3 m/s), the density of the obtained briquettes does not change significantly (not more than 3%). The average density of briquettes obtained in laboratory tests is higher than in simulation, respectively, 8.8% for briquettes made of calcium hydroxide and 4.7% for briquettes made of copper ore concentrate, which can be considered a satisfactory result. Each material requires specialist knowledge, much of which has been gathered from years of specialist R&D work. An analysis of two material (calcium hydroxide and cooper concentrate mixture) models and four peripheral roller speeds (from 0.1 up to 0.3 m/s) showed that the stress distribution characteristic is mainly related to the geometry of the forming elements. 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. Modelling performed for four values of the circumferential speeds of the rollers shows that the average stress values for calcium hydroxide are in the range of 25÷28 MPa, and for a mixture based on copper ore concentrate, 36÷40 MPa. For those clients who need to precisely place the cutter on the hide, and claim that a steel rule die cannot perform this task – we have developed the C-Thru cutter range of transparent cutters. (see below).

Anyone who has ever worked with a roller ironer can't imagine ever doing without it again! Our Roller Irons have two open heating shoe ends, ideal for ironing tubular pieces. The Hydraulic Roller Press has solid-forged, counter-rotating rollers with no hollow shaft resulting in long equipment lifetime. The rollers have an optimum diameter to width (D/W) ratio that: Up to 40% higher torque for the same installation dimensions compared to the PLANUREX 2 roller press drive and competitors products One of the parameters that characterise the deformation region in a roller press is the amount of pressure exerted on the surfaces of the forming elements. Its value, considering the physical and mechanical properties of the compacted material, makes it possible to determine such parameters of the produced briquettes as density distribution and strength.

In addition to more traditional cutters, ARROW CUTTERS specialises in manufacturing cutters for converting more challenging materials – like millboard and MDF. 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. In addition, we retain a supply of specialist profile cutting rules specifically for this application. Including serrated rules and also zigzag rules that reproduce the pattern of pinking shears. The press frame accommodates the floating and fixed rollers as well as the hydraulic pressurizing cylinders and housing. Different roller surfaces are used (solid form, tires or segments) to meet the specific requirements of the feed to be processed. The materials used are tailored to customers’ needs and the requirements of the processed material.Theyare sufficiently wear-resistant to ensure maximum service life and minimum expense, whereby conventional pressing tools can be refurbished and re-used. The material is squeezed and smashed continuously in the roller cover, and the harmful dust is not easy to spread. At the same time, the noise of the roller press is much smaller than that of the tube mill because of no impact.

And regardless of your selection, all tools are covered by ARROW CUTTERS famous, “If it doesn’t work, you don’t pay for it” no-haggle guarantee. Diversified product solutions, flexible process system configuration, and superior cost performance. Roller press categories are based on the relevant bearing size. The smallest type delivers a pressing force of 400 kN, while larger presses can generate a pressing force of up to 20,500 kN. Equipment weights vary between 2 and 400 tons. Dies, formes, dinking boards, knife tools - to list but a few of the myriad names used to describe the humble steel-rule cutter. However, regardless of what term you use for your tooling, ARROW CUTTERS can fulfil your requirements. The experimental tests indicate a decrease in the strength of briquettes with an increase in the speed of the peripheral rollers. It was not observed in the simulation. This is due to the assumptions made in the model.Reduce steel consumption. When grinding cement, the ball mill has a yield of 300~1000g/t, and the grinding system of the roller press has a yield of 0.5g/t, so it can meet the requirements of white cement. ADVANCED Range cutters are available for any application, and can be specified with a range of upgrade options including: “Hi-Performance” cutting rule, laser cut baseboards, or solid aluminium baseboards. 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.

Upgrading a conventional ball mill with the Hydraulic Roller Press for semi-finish setups can increase production by up to 100 per cent or more, while also reducing specific power consumption by approximately 30 per cent. Our unique roller wear surface TRIBOMAX® is the strongest and most durable surface available, and is applied to the Hydraulic Roller Press rollers using a special state-of-the-art welding technology. TRIBOMAX® has a 25,000-hour minimum guaranteed lifetime for Clinker grinding applications and can be designed to guarantee up to 40,000 hours of lifetime in select cases. We also provide conventional wear surface for applications in which your feed materials don’t have high abrasiveness.In a pre-grinding setup, the Hydraulic Roller Press grinds the fresh feed and a specified amount of recirculated pressed flakes. This material mix then undergoes finish grinding in a conventional ball mill circuit. In comparison to a conventional ball mill system, this configuration provides an increase in production of approximately 25 per cent and a reduction in specific power consumption of approximately 10 per cent. With a touchscreen and foot pedal controller, operating the R02036 Rotary Iron is a breeze. And with a 2-litre water tank, you can keep ironing for longer without needing to stop and refill. 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. The results of experimental tests were used to analyse the power consumption. They included the briquetting of calcium hydroxide at peripheral speeds of the work rollers of 0.1, 0.2, and 0.3 m/s. A comparison of the power consumption values with the results of experimental studies shows some discrepancies with an increase in the strain rate. At the same time, a perfect convergence of the power consumption values is observed at a speed of 0.1 m/s, which is approximately 2 kW ( Figure 14). Heat and steam distribution are perfectly even. Even the most demanding fabrics are smoothed gently and easily.

Safe and energy-efficient, the steam is automatically turned off after 15 minutes when you take a break. If the electricity should be suddenly disconnected, the roller press can still be opened by hand (in compliance with IEC safety standards). Minimum maintenance required. The material is crushed by static pressure, the equipment runs smoothly, the noise is low, and the dust pollution is less.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. 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. Safe and energy-efficient, the steam is automatically turned off after 15 minutes when you take a break. If the electricity should be suddenly disconnected, the roller press can still be opened by hand (in compliance with IEC safety standards).
