Who thinks that sifting always works the same way is sorely mistaken. The right sifiting technology is crucial for quality, efficiency, and cost-effectiveness. Plansifters the universal sifting solutions Anyone who thinks that sifting simply works the same way is sorely mistaken. Depending on the requirements, product and objective, different types of sifting machines are used in industry – each with its own strengths and special features. Whether in the food, pharmaceutical, plastics or chemical industry: choosing the right sifting technology is crucial for quality, efficiency and cost-effectiveness. 1) Vibratory sifters – the classic choice These are mostly used for simple applications such as control sifting, also known as safety sifting. In this process, foreign particles are separated from the ‘good’ product. In applications where oversized particles are to be sifted out, the term control sifting is not used, but the process is simply the same. In many cases, vibratory sifters are also used here. They can also be used for dedusting bulk materials. The fine particles are sifted out. Compared to other sifting

Insects such as buffalo worms and mealworms are a sought-after source of protein as sustainable feed as well as for a climate-friendly diet. RHEWUM has the technology for gentle sieving of live larvae on an industrial scale. Like many other insects, buffalo and mealworms are a high-quality source of animal protein. Buffalo worms are the larvae of the glossy grain mould beetle and grow to about 7 to 11 millimetres in length [1]. Worm, or not Flourworms are the larvae of the flour beetle and grow considerably larger than buffalo worms, reaching up to 40 millimetres. Both are larvae of the black beetle family and are not worms in the true sense, as they each have three pairs of legs. Nevertheless, for the sake of simplicity, the buffalo and mealworms are referred to here synonymously as larvae and worms. Climate-friendly proteins Compared to other farm animals, the breeding and keeping of buffalo and mealworms is much more climate-friendly, which means that worms are becoming increasingly important as a component of a sustainable diet. For each kilogram of edible protein from insect larvae, a similar amount of energy is required as for each kilogram of protein from milk, chicken,

The specific properties of a wire cloth can be precisely described and defined geometrically by the type of weave, wire diameter and mesh counts. GeoDict software Haver & Boecker uses the GeoDict software to determine in advance the best suited cloth configuration for the particular area of application. By simulating different situations, it is possible to optimize existing wire cloth specifications and develop new ones. 3D-Cloth Model Using specific cloth parameters resulting from the type of weave, aperture width, pitch and wire diameter, Haver & Boecker can depict the structure of single-layer cloths and multiple-layer cloths as a real 3D model. Flow Behaviour Behaviour of the respective cloth or cloth laminate in various fluids such as air, water and fuel as a function of flow velocity or differential pressure. Geometric Pore Size 
For the Geometrie Pore a characteristic value is determined that describes the Diameter of a round sphere that is just able to pass through the wire mesh. For the pore size (PG), Haver & Boecker states the value Xmax (= maximum pore size) as reference.

Properly selected sieving machines will improve the quality of the additive powder product, increase the product output, and prevent clogging of the screen mesh. Food additive screening Food additives are compounds or natural substances added to food for the purpose of improving the quality of food, such as color, fragrance and taste, as well as for the needs of anti-corrosion and processing technology. At present, there are 23 categories and more than 2000 varieties of food additives in China, including antioxidants, bleach agents, leavening agents, colorants, flavor enhancers, nutritional enhancers, preservatives, sweeteners, flavors and so on. Because food additives contain a little oil, with rotary vibration sieve is easy to block the mesh situation, Dingcoma corporation production of food additive sieving machine can play its screening advantages. Chosing the right vibrating screen Food additive manufacturer needs to screen and separate their food additive powders into 10 mesh, 18 mesh, and 35 mesh grades. Their existing airflow screening machines have a maximum throughput of only 500 kg/h. To increase productivity,

In his production chain an American manufacturer will no longer use two machines for screening his plastic granulate, but only one: the Rhewum wafl with two screen decks. Pavement markings have been used since the beginning of the 20th century. Today they are part of the modern street scene and without them we would sometimes lose orientation. The line markings create a clear and safe traffic guidance. The products of the world’s leading North Carolina-based manufacturer are not only used on roads and highways, but also on taxiways, take-off and landing runways, parking lots, intersections and in all types of commercial, construction, government, industrial and architectural environments. So these markings help drivers, pilots and pedestrians to move safely in the right direction. The exact process of producing road markings will not be discussed in detail at this point, as it is quite complex. However, plastic granulate is processed in the production of road markings, that must be dewatered. With the help of the Rhewum wafl the water can be perfectly separated from the product and a low residual moisture of approx. 8 percent can

New Long-Stroke Screening Machine by Engelsmann Regardless of whether you are mixing, conveying or dosing – when it comes to handling fragile bulk solids, sensitivity is required. This particularly applies to screening machines, as the back and forth movement on the screen surface places a relatively high mechanical stress on the screening product. If this aspect is not taken into consideration when choosing and designing your screening machine, it can lead to an unwanted breakdown of grains which then results in an increased number of over- and undersized particles in the product, causing it to be no longer fit for purpose. A screening process that is gentle to the product is therefore a decisive criteria for many facility operators when it comes to choosing the right screening machine. An additional issue that screening machine suppliers have to face – aside from ensuring the quality of the screening product – is the demand for a machine handling that is a simple as possible. This requirement is commonly

Plastic recycling The high-frequency sieve was already frequently used for sieving dust and grit in feed and pet food applications. The desire was to be able to change a sieve deck quickly (<30 sec), but above all to be able to realize a higher sieve effeciency. The machine is then further developed and is now used for plastic recycling, for example, where the machine is placed just before the color sorter. Dust is disastrous for the lenses in a color sorter and so sieve must be sieved thoroughly. The unique thing about this system is that the screen deck can be automatically tensioned and relaxed. It looks like an elastic that attracts you, and causes a larger amplitude when tensioning / relaxing. wedge-shaped flakes, which get stuck in the screen deck, are fired from the deck. Closing the deck is therefore almost impossible. The machine vibrates high-frequency and provides higher sieving efficiency than conventional vibrating sifting machines. This is possible because only

From MAJOR WIRE Industries Ltd and HAVER & BOECKER Self-cleaning screen media have become the ones to use especially for processing loose, bulk materials. With the FLEX-MAT from our partner company Major Wire, Haver & Boecker now offers a new screening media generation where the design significantly improves the self-cleaning effect. As opposed to the currently available products, the horizontally crimped warp wires are fixed not by weft wires in the FLEX-MAT screen media, but exclusively by recyclable PU connections. In doing so, each wire can individually vibrate throughout its entire length so that caked up material and jammed particles are more effectively prevented. In addition to the high flexibility of the wire, the smooth screen surface provides a considerably longer lifetime when compared to conventional screen sections. Clean: from very coarse to very fine: Self-cleaning screen media up to now have been available with opening sizes of 2 mm to 28 mm and are traditionally suited only for difficult to screen

HAVER Industrial Wire Screens When screening loose, bulk materials, and especially when handling abrasives products such as stone, gravel or crushed stone, screen decks are subjected to extreme loads. This leads to more frequent replacement of the wire mesh, which in turn results in undesirable downtime. An alternative is using polyurethane screen decks. Although they have longer lifetimes, they also have less open screen area and so there’s a loss of screening capacity. To compensate for this an additional screening machine often has to be put into operation. One solution offers all the advantages: TY-WIRE Hybrid screening decks combine all the advantages of wire and polyurethane screening decks because TY-WIRE consists of wire mesh that is encapsulated in polyurethane using a special process. The result is a screening deck with a significantly greater open area when compared to conventional PU screening decks. At the same time, they have a lifetime that is 4 to 6 times longer than wire screen

Square and rectangular wire mesh cloth The standard is already cutting edge. Haver & Boecker stocks a wide range of standard wire mesh as to ISO 14 315 and ISO 9044, which therefore allows customers to find the right mesh for the job at hand. Square mesh wire cloth. Whenever precise cut sizes for loose materials are required or whenever long particles need to be screened, it is essential to use rectangular opening mesh. For processing coarser loose materials, the type of weaving determines the screening behaviour. Wire mesh pre-crimped on both sides, e.g. DOKA weave and DOKA mesh, causes good rotation of the screened material because of its rough three-dimensional surface. The material has much greater chances of falling through the mesh openings and thus leading to successful screening. Moreover, the fine particles are brought to the screen surface more quickly, which accelerates the entire screening process. The faster the fine particles are screened out, the more screen area is left for screening
