How does a screw press work?

Screw press (or screw press)- This is equipment used in various industries, such as processing materials, oil production, agriculture, as well as in the chemical and food industries. It works on the basis of a rotating screw (screw), which moves the material through the pressing camera. Consider the principle of its work more details:

The main components of the screw press:

1. The screw (screw) is a rotating spiral that moves the material along the press chamber.

2. The press chamber (or cylinder) is the cylindrical part through which the material passes, subjecting to compression.

3. The output is the place through which the processed material is pushed out.

4. A nut (regulatory mechanism) is a device for regulating pressure created in the press chamber, as well as adjusting the degree of compression of the material.

The principle of operation of the screw press:

1. Material feed:

  The material that must be processed (for example, seeds, raw materials, oils or solids) is loaded into the back of the press chamber. It can act through a conveyor tape or manually, depending on the type of installation.

2. Moving the material with a screw:

  A rotating screw moves the material forward along the press chamber. The screw performs two main actions: transports the material and compresses it. As a result of rotation, the screw begins to pull the material that, as they move through the camera, is subject to compression and friction.

3. Pressing and compression:

  During movement through the press chamber, the material is exposed to pressure, which is created by a rotating screw. This pressure leads to the separation of various components of the material (for example, oils from seeds in oil presses) or compression of solid materials.

4. Exit of the processed material:

  After compression, the material goes through the output. In the case of oil presses, the oil (or other liquids) is pushed through the filter or hole, leaving solid residues. In other cases, such as the pressing of wood waste or plastic, the result may be a dense briquette.

5. Pressure adjustment:

  To achieve the desired level of compression or release of components, pressure adjustment is used, which may vary depending on the requirements. For example, if the screw begins to rotate at a higher speed or the pressure increases, then the material will be subjected to stronger pressing.

Application of the screw press:

- oil presses: are used to extract oil from seeds (for example, sunflower, soy, sesame seeds).

- processing of wood waste: pressing of wood pellets or briquettes.

- Agriculture: processing of animal feed.

- Chemical and food industry: for the liquefaction of various substances or the release of liquid components.

A screw press has high efficiency, compactness and the ability to work with various materials, which makes it a popular tool in various fields of industry.

A double -disc friction press is a widely used mechanical press, the principle of its operation is to use friction between two friction discs for transmitting power and movement.
