Magnetic separators / filters for dry mixtures - manual cleaning

Telescopic magnetic separators / telescopic metal separators (MSV)

Telescopic magnetic filterThis type of magnetic separator is intended above all for separation of metallic magnetic particles from bulk materials with good loose properties. So called manetic extending grates on which all metallic particles are trapped represent the basic part of the magnetic separator.

Structure of the telescopic magnetic separators

Magnetic grid, finger magnet They are fitted with permanent magnets, specifically with either ferrite magnets or those based on rare earth metals NdFeB where several times higher magnetic induction (magnetic force) is achieved; the grates fitted with these magnets are capable of catching even not fully magnetic particles.

Developmnet, production, construction, serviceThese grates are mostly installed as a pair in the box structure designed in accordance with dimensional requirements of the customer. The upper grate contains always one magnetized tube less in order the tubes could create fall down labyrinth at subsequent shifting. This way the separated material contact with magnetic pipes is provided. The separation done in this manner is highly efficient.

The grates (finger magnets) can be also installed separately e.g. in a hopper. In this case, we provide the grates with so called spreading roofs which are positioned always above the level on the magnetized tubes so that to direct material evenly on the magnetized tubes.

Telescopic magnetic separator / telescopic metal separator - UP (MSV UP)

On contrary to the type described above, this magnetic separator has several crucial benefits and innovative features.

Telescopic magnetic separator - UP (MSV UP)

  • Its magnets are firmly attached to the separator body so there is no risk of injury caused by magnetic core catching on cleaning, e.g. to a metal floor or another metal structure.
  • Due to that, a risk of magnetic core damaging is significantly lower.
  • Easy cleaning.
  • Better safety at work.
  • On cleaning, no material gets onto the magnetic cores.
  • No cleaning agents needed.
  • Damaged pipes can be replaced easily.

Magnetic grate STEFF

Telescopic magnetic grate STEFFThe main reason for the manufacture of this new magnetic grate type consists in the increase of the health protection and observing working safety rules. Magnetic cores are parts of the covering stainless-steel pipes and the entire grate forms a single unit during protrusion.

Another reason consists in the minimizing of the grate damaging risk. In case the STEFF grate and cleaning preparation are used, no magnetic core contamination can take place.

Grate cleaning

Steff grate cleanEither using the traditional technique when the magnetic cores are pulled from the stainless-steel pipes and metal particles are falling out automatically, or utilizing specially designed cleaning preparation. Cleaning is most comfortable, very fast and prevents the magnetic core damaging.

Emergency magnetic separator of dry mixtures (PMS)

Emergency magnetic separator of dry mixtures If, from time to time, you need to pour a smaller quantity of a bulk material manually, this stand fits to your needs. Together with the magnet to be used in a hopper, it will form a simple and cheap dry mixture separator.

Operational steps

  • First of all, insert e.g. plastics bag into the stand head, or place a box under the stand
  • Magnet to be used in a hopper place into the stand head
  • Pour the material manually through the magnets
  • Metal particles are caught on the magnets
  • Only clean material (without metal particles) will fall into the bag or box

Main stand benefits

  • Tilting head
  • Stand is installed on wheels
  • Height-adjustable

Pipe systems

In order to facilitate the installation of our separators into piping as much as possible, we offer the delivering of standard transition elements of the types "square-circle" and "circle-square".

Available in our stockFlow magnetic separator for tanks (MF CIS)

Flow magnetic separator for tanksThis tank-type flow magnetic separator serves to the separation of metal impurities from dry powder materials of food, chemical or raw-material processing industries; during unloading, the material is transported from the tank using pressurized air.

Developmnet, production, construction, serviceThe separator consists of two fully removable parts: magnetic component and separator body. Remove the component with magnetic pipes from the magnetic separator body and, using handrail, pull the magnets to the upper position. This way stainless steel pipes become demagnetized so metal parts fall off.

Flow tank separator of powder materialsMagnetic separators are ended by parallel threads with a possibility of equipping them with transitional components adapting them to other dimensions. Magnetic separator can be connected to the pipeline DN 80. However, we are able to adapt the separator to various input and output dimensions, as well as types of ending.

The device is made of a stainless steel 1.4301 and its surface is treated by sanding. By request also separators in polished versions can be manufactured.

Separator benefits

  • Very easy manipulation and cleaning.
  • It meets food industry standards.
  • It is manufactured of the stainless steel 1.4301.

Materials that the separator is capable of sorting

  • Materials transported from tanks using pressurized air.

Tank separator design

Průtokový magnetický separátor pro cisternyMagnets are inserted into the stainless steel casing so they are protected against damaging and their cleaning is very easy, fast and comfortable.

The total device weight is 14 kg. Device handling may be managed by a single person. The separator is completed with silicone sealing (meeting food industry standards). Pipes in which magnets are located are welded to a removable component. Separator consists of 4 pieces of magnetic pipes with the diameter of 30 mm. The component with magnetic pipes is connected to the separator body using a bayonet closure, including a sealing, and is secured by wing nuts.

Magnetic separator is equipped with very strong rare-earth NdFeB magnets with the magnetic induction 10.400 Gs, capable of catching even very small magnetic particles. By request we can also use magnets with the magnetic induction higher than 14.000 Gs and with the temperature resistance of 180 °C.

Magnetic separator cleaning

Removing of caught metal impurities is very easy. First of all release wing nuts and bayonet closure. Then pull the component out of the separator body. Then release the fuse and pull the magnets out of the magnetic pipes. As soon as the pipes are clean, magnets can be inserted back to the component.
