Sieving Machines
Sieving machines were indispensable devices several years ago as well as they are in today’s day in day out processes in industry and trades. A previously performed accurate analysis of particular raw materials, additives and supplies by means of sieving machines is often necessary and represents an important premise to achieve proper results and to produce perfect products. By considering these aspects, we provide such systems that help achieving optimal results during the fabrication of products. Our sieving machines provide high precision and function during product analysis by sieving. As mentioned before these sieving machines are applied in various areas. The sieving machines analyze various materials with a portfolio covering sands, soils and construction materials as well as food and chemical products. Therefore it is essential that the sieving machines cover various ranges of mesh sizes, since you obviously can’t sieve all favored chemicals only with a rough mesh. Especially in laboratories sieve analysis with traditional sieving machines aren’t sufficient anymore, but instead there are high-end products required, that are a huge assistance due to a digital indication of the sieving process. Often it is required that the sieving machines support dry sieving as well as wet sieving. Therefore we provide sieving machines that easily support both procedures. While selecting the adequate sieving machine, it should be considered, whether the devices are compatible with different filling capacities. These required capacities are to consider while selecting a machine with an adequate filling capacity that must always be followed. As additional equipment we have also different analyzing sieves for the sieving machines in stock. With these analyzing sieves sample amount of various branches can be separated and classified. All analyzing sieves are produced following current standards and stand out due to their high accuracy and stability. Additionally you will also find ultrasound cleaners in our assortment which will help you clean up the used sieves as efficiently as possible. If you can't find the sieving machines you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: +44 (0)2380 987030 and our technical staff will advise you regarding our measuring instruments. Our engineers and technicians will be happy to help you with the diamond testers, and of course, with the other products in the field of regulation and control, and scales and balances.

Further information on sieving machines / sieve devices
In sieving machines, the material is separated through a wire-mesh, due to which the smaller particles are separated by different mesh widths from the larger particles. There are analyzing sieves with different sizes for these tasks that have a range of mesh sizes to provide an optimized solution for sieves of different materials. Therefore it should be considered that even those sieves might get polluted with time and thus they have to be cleaned out properly. The ideal solution for that are ultrasound cleaners in order to assure a long-term application of the analysis sieves at the Sieving machines. Apart from that an ideal analysis can only be performed, if the sieves do not destroy the sieving results due to contamination. In order to have the proper sieve results within a short time and for an ideal repeatability of those results, some Sieving machines perform three-dimensional sieving movements, during which the sieve material is accelerated vertically through the meshes, and spread in a circular movement all over the sieve surface. The principle, which some of our sieving machines work with, saves time for the operator and often spares the manual sieving that might in other cases be necessary afterwards.

Throw-action sieving machines: Screening machines are sieve machines, in which the vertical throwing motion is overlaid with a slight circular motion. It results in a distribution of the sieving sample over the whole sieving surface. By that the particles are accelerated in a vertical direction. Due to the throw-action they carry out free rotations in the air and alternate their positions. According to the movement carried out in the air, it might occur that those particles that apparently do not fit the gutter of the sieve might be sieved after all. If the particles are smaller than the mesh they fall right through it, but if they might be larger in their length and cannot pass the mesh, they are vertically accelerated and might change their direction so that they might now pass through the meshes, if they have a smaller width instead.

Tapping sieving machines: In horizontal sieve machines the horizontal circular motion is overlaid by slight vertical motions. The vertical motion is triggered by a so called tapping impulse from underneath.
