Palm grinder machine

Types of Palm Grinder Machines

The palm grinder machine is essential in palm oil extraction and refining. There are several varieties of palm grinder machines designed to cater to various extraction processes. Some of them include:

• Hammer Mill :

  The hammer mill is a popular palm grinder machine in the palm oil extraction process. It basically uses massive metal hammers to strike and grind palm fruit bunches. It has a robust feeding inlet that lets in a large quantity of palm fruit, increasing productivity. Hammer mills also possess interchangeable screens that allow extractors to control the consistency of the palm oil that is being processed. One amazing thing about hammer mills is that they can process up to 60–500 kilograms of palm fruits every hour, depending on the model. A downside, however, is that no matter the secondary product that is being processed, only one primary product is extracted from the hammer mill. Also, the oil cake usually has a very high residual oil content.

• Disc Mill :

  A disc mill is another grinder for palm nuts and fibers. The device also has a metal plate and a round steel disc. Inside the steel disc are radial slots that hold palm nuts and fiber firmly for grinding and separating. Compared to a hammer mill, disc mills have less noise. In addition, they produce less dust, ensuring a safe work environment for workers and extractors. More importantly, disc mills are known to extract about 90% residual oil from the palm kernel cake.

• Screw Press Palm Oil Grinder Machine:

  This grinder machine follows a different process entirely. It uses a helical screw within a cylindrical cage lined with mesh or perforated and heated steel. The screw draws the palm fruit fibers into the cage. As the fruit fiber moves through the cage, it gets pressed against the walls. Pressure builds up, and palm oil seeps through the mesh, flowing out into a separate collection. The screw press can extract up to 40% oil from palm fruits and is also suitable for excess fiber extraction.

• Rotary Palm Nut Grinder Machine :

  With a rotating cutter, the rotary palm nut grinder machine smashes the palm kernel into smaller pieces. It operates with a motor and is then fed into a screw press for pomace extraction. It works independently of hammer mill extractors and is known to be less noisy than them.

Specifications and Maintenance

Specifications for a typical palm nut grinder may vary depending on the technology and design. Nevertheless, here are common specifications and their descriptions.
