wood?<\/strong><\/h2><\/h2><\/div><div class=\"fusion-text fusion-text-7\"><p><span style=\"font-weight: 400;\"><span style=\"text-decoration: underline;\"><span style=\"color: #0000ff;\"><strong><a style=\"color: #0000ff; text-decoration: underline;\" href=\"https:\/\/castulik.sk\/en\/shredder\/mn300-1-0159\/\">A knife mill<\/a><\/strong><\/span><\/span> is often perceived as a plastics\u2011processing machine, yet its fundamental design makes it equally well\u2011suited for efficient wood shredding. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">From a construction standpoint, knife mills resemble wood chippers with horizontal material feeding, typically using a vibrating chute and feed rollers &#8211; technology that has been in use for decades. The key difference is that in knife mills, the material is fed vertically from above into the shredding chamber, usually by free fall. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The cutting tools consist of flat knives mounted on the rotor carriers and on the stator of the shredding chamber. The knives are positioned at an inclined angle relative to each other, creating a scissor\u2011like cutting effect.

A different force is required to shred wooden beams with a cross\u2011section of 2\u00d72 cm compared to beams of 10\u00d710 cm. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Likewise, the impact on the hopper walls differs significantly between a 200 g piece of wood flung by the rotor and a 2 kg piece.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For our knife mills, for example, the following applies:<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u2013 <\/span><b>MN300\/400 knife mill<\/b><span style=\"font-weight: 400;\"> \u2013 power input up to 22 kW \u2013 suitable for wood pieces with a cross-section up to <\/span><b>30 cm\u00b2<\/b><span style=\"font-weight: 400;\">,<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> \u2013 <\/span><b>SG400\/600 knife mill<\/b><span style=\"font-weight: 400;\"> \u2013 power input up to 55 kW \u2013 suitable for wood pieces with a cross-section up to <\/span><b>60 cm\u00b2<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><b>Method and intensity of feeding material into the knife mill<\/b><b><br \/><\/b><span style=\"font-weight: 400;\"> The method and intensity of feeding material into the mill directly influence the required machine size. The higher the instantaneous shredding performance (i.e., more aggressive feeding), the more robust the machine must be and the higher its electrical power demand. <\/span><\/p>\n<p><b>Required output particle size<\/b><b><br \/><\/b><span style=\"font-weight: 400;\"> The required particle size determines the screen\u2011opening size in the knife mill. It is important to keep in mind that the smaller the particle size, the smaller the screen openings. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">With soft, non\u2011dried wood, the elasticity of the material must also be considered. Elastic wood shred is pressed into the screen openings, where it expands and clogs the screen. The result is reduced shredding performance and a finer output fraction.  <\/span><\/p>\n<p><span style=\"font-weight: 400;\">This issue is addressed by selecting significantly larger screen openings than the desired final fraction and larger than would be used for dry wood.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When looking at wood shred, the orthotropy of wood becomes very apparent. The chips take the form of needles and splinters, because wood is much easier to shred along the fibre than across the fibre. <\/span><\/p>\n<\/div><div class=\"fusion-title title fusion-title-3 fusion-sep-none fusion-title-text fusion-title-size-two\" style=\"--awb-font-size:32px;\"><h2 class=\"fusion-title-heading title-heading-left\" style=\"margin:0;font-size:1em;line-height:1.2;\"><h2><b>Single-shaft shredders for processing wood waste<\/b><\/h2><\/h2><\/div><div class=\"fusion-text fusion-text-9\"><p><span style=\"font-weight: 400;\"><span style=\"color: #0000ff;\"><strong><span style=\"text-decoration: underline;\"><a style=\"color: #0000ff; text-decoration: underline;\" href=\"https:\/\/castulik.sk\/en\/shredder\/picus_600_15kw\/\">Single-shaft shredders<\/a> <\/span><\/strong><\/span>with a cycling pusher mechanism have, over time, become something of a standard for processing wood offcuts in the woodworking industry. They offer a number of undeniable advantages. They operate in a simple rhythm: dump the bin and walk away. The knives and other components of the shredding chamber are resistant to nails, metal staples and straps, thin sheet metal, and similar contaminants. They also run with relatively low noise.    <\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, there are limitations. The rotor knives run at a relatively large distance from the screen surface, which means they clean the screen only lightly and struggle to remove material lodged in the openings. As a result, screens with apertures smaller than 12 mm cannot be used. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">And something many users do not realise is that the shear gap between the rotor and stator knives in single\u2011shaft shredders is typically around 1\u202fmm. The result is an imperfect cut. This leads to higher energy consumption and more dust in the output compared to shredders with a precise cutting action.  <\/span><\/p>\n<p><span style=\"font-weight: 400;\">This characteristic becomes especially noticeable with soft, non\u2011dried wood, where the shredded granulates show signs of tearing rather than cutting \u2013 the granulates appear \u201chairy\u201d due to torn fibres. Such material has high internal friction, slides poorly along surfaces of the discharge section, and tends to form strong arches in boiler hoppers. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Additionally, these shredders, operating at relatively low rotor speeds, struggle with the elasticity of non\u2011dried wood. The wood resists the action of the rotor knives through elastic deformation, which reduces the shredder\u2019s throughput. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">A separate challenge for single\u2011shaft shredders is the processing of long pieces and wide boards. If the length of a beam exceeds the height of the shredder\u2019s hopper by more than twice, it will tip over the hopper edge and fall out of the machine. If a board is wider than 50% of the rotor length, the rotor knives mill grooves into it, but the board cannot shift along the shaft and it ends up \u201csitting\u201d on the rotor, and the shredding performance drops to zero.  <\/span><\/p>\n<\/div><div class=\"fusion-title title fusion-title-4 fusion-sep-none fusion-title-text fusion-title-size-two\" style=\"--awb-font-size:32px;\"><h2 class=\"fusion-title-heading title-heading-left\" style=\"margin:0;font-size:1em;line-height:1.2;\"><h2><b>Characteristics of knife mills and their performance in wood shredding<\/b><\/h2><\/h2><\/div><div class=\"fusion-text fusion-text-10\"><p><span style=\"font-weight: 400;\">Knife mills belong to the group of shredders that deliver a very precise cutting action. The shear gap between the stator and rotor knives is set to around 0.2\u202fmm. For this reason, compared to single\u2011shaft shredders, they handle the shredding of veneer (a thin wooden \u201cfoil\u201d) and bark (they easily cut through the fibres in the bark) exceptionally well.  <\/span><\/p>\n<p><span style=\"font-weight: 400;\">When processing standard wood offcuts, the material is cut at high rotor speeds (around 700\u202frpm). The rotor knives operate only a few millimetres from the calibration screen. This results in effective cleaning of the screen openings, the ability to use screens with extremely small apertures (sometimes as small as 0.5\u202fmm), a low proportion of dust in the output, relatively smooth chip surfaces, reduced energy consumption, and high shredding performance.  <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Both rotor and stator knives have a cutting\u2011edge angle significantly below 90\u00b0. For this reason, these machines are not suitable for materials that may contain steel contaminants or minerals. Such impurities cause rapid wear of the knife edges, making operation economically inefficient. The same applies to materials with mineral inclusions.   <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Among the disadvantages of knife mills are the high noise levels during operation and the need to feed material gradually, within the limits of the machine\u2019s maximum throughput.<\/span><\/p>\n<\/div><div class=\"fusion-title title fusion-title-5 fusion-sep-none fusion-title-text fusion-title-size-two\" style=\"--awb-font-size:32px;\"><h2 class=\"fusion-title-heading title-heading-left\" style=\"margin:0;font-size:1em;line-height:1.2;\"><h2><strong>How to choose between a knife mill and a single-shaft shredder.<\/strong><\/h2><\/h2><\/div><div class=\"fusion-text fusion-text-11\"><p><span style=\"font-weight: 400;\">Both high\u2011speed knife mills and slow\u2011speed single\u2011shaft shredders have their own advantages and disadvantages.
