extruder is actually an industrial device designed to form different materials by passing them through a specific mold. This process involves compressing raw materials that make them arbitrarily.
Extruder and its applications in various industries
The extruder machine has many applications in a variety of industries, including plastic production, food, compact charcoal, iron rolling, animal feed and poultry, etc. The raw materials that the machine feeds are usually in the form of powder or granules and, after applying heat and pressure by the system, are in various forms of rod, sheet, filament or even finished product.
Types of extruder
There are various industries that use extruder. The device, also called the pressure device, has a simple mechanism and function: compression along with heating to the raw materials. The type of raw material is your final template and settings that determine how the extruder operates.
Therefore, the structure of the extruder device used, for example in the feed industry, will not have a fundamental difference with the sample used in the wood industry.
Although you should note that despite this similar structure, there are different types of extruder that have different capacity, power and power than each other, and naturally their prices are different. You should also choose one of the following models to suit your needs:
Single -spiral extruder device (single marshon)
The most common type of extruder is a single screw or single -drive model that uses a single compression rod to apply pressure on the raw materials. This species is mostly used in the plastics, food and livestock and poultry production industries.
Extruder of two spirals (two marshons)
Another important type of extruder is the Mardon model. In this machine there are two twin screws that are twin madons and are paired or paired together in a compartment. The movement of these compressive rods can also be in the opposite direction.
The production capacity of two -coil extruders is up to 3 times faster than the single Mardon models and can have up to 6 tonnes per hour. These devices are mostly used to produce sensitive materials and polymer, whose precise composition is of great importance.
Piston extruder
The simplest type of extruder is the piston model whose mechanism is to press raw materials to the output mold. Contrary to imagination, the pressure in this device is much higher than the Mardon models and has a more accurate formation.
Cold extruder machine
In these devices, no heat is applied to the material while compressing and mixing with normal temperatures. These models have much lower performance speed and are mostly used to produce different foods or doughs.
Warm extruder
If you need heat to better combine the raw materials in the compression process, you should use hot extruder. This device can create a lot of heat to make the extrusion process as best as possible. This model is mostly used to produce high -density products.
