580 Roller Iron Steam press

Product Information

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.

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. 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. Uneven loads, extreme axial and radial forces, high dust generation – the grinding of iron ore, limestone and clinker is marked by harsh working conditions. High-pressure rolling mills and rotary kilns are particularly demanding applications that call for maximum performance and reliability from the drive systems. The grinding process must be guaranteed energy-efficient and reliable at the same time. Our planetary gear units have been used as drives in roller presses and rolling mills for decades. The product portfolio during that time has been continuously optimised and expanded. Today our gear units are the perfect solution for rolling mills and roller presses. Their low weight reduces loads on gear units and machines. High radial and axial additional forces exerted by universal-joint shafts and floating-roller acceleration are absorbed by the standard bearing system. The high overload capacity here ensures operational reliability and stabilises your process. Both the cement ball mill and the cement roller press have their own advantages and disadvantages, but in actual production, the cement roller press has the advantages that the ball mill does not have, mainly reflected in the following points. The material after grinding is greatly reduced in both particle size and the Bond function index, thereby greatly improving the grinding condition of grinding machine, and the power consumption of the entire cement grinding system is significantly reduced. It can save25-50% energy compared to traditional grinding methods, and the annual electricity saving are considerable.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. 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. 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. 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 vast majority of cutters used in the UK today, are used within the printing industry. And it was making cutting and creasing formes for print that first established ARROW CUTTERS reputation for excellence.

Even steam and heat distribution guarantee perfect ironing results! The heating shoe lies below, as on professional hot mangles. High grinding efficiency, increasing production and energy saving. In the ball mill, the material is subjected to pressure and shear, which is the combined effect of these two forces. In a roller press, the material is only under pressure. Tests have shown that during the crushing process of the particulate material, the strain generated by applying onlypure pressure is equivalent to five times the strain generated by the shear force. Our engineers will take all relevant factors into consideration to suggest the type of wear protection most suited to your application choosing from three different technologies: 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.

Hydraulic pump power

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.
