Ultrafine Grinder
The ultrafine grinder specially developed for the crushing of raw materials for aquatic feed. It can crush the raw materials to 60-80 mesh to meet the production needs of aquatic feed pellet.
Since aquatic animals have low food intake, short digestive tracts, and poor digestive capacity, the raw materials used to produce aquatic feeds require very low particle sizes to improve the digestibility of feeds by aquatic animals. Therefore, the production of aquatic feeds generally requires secondary grinding, which can be done with ordinary hammer mill and ultrafine grinders.
The ultrafine grinders we produce are widely used in the crushing of various aquatic feed raw materials and can well meet the production needs of aquatic feed.

How Does The Ultrafine Grinder Work?
The ultrafine grinder is a machine that pulverizes materials by the impact of hammers under the action of centrifugal force through the high-speed rotation of the pulverizing disk. The pulverized materials enter the pulverizing and grading chamber, and are graded by the balance of air power and centrifugal force through the rotating grading wheel. The separated coarse materials return to the pulverizing chamber from the bottom of the inner cavity of the guide cover and are repeatedly pulverized, so that the fine materials are sucked into the grading impeller and enter the pulverizing discharge chamber.

Advantages of Ultrafine Grinder
- Integrated structure. The crushing chamber and the grading chamber are integrated, and crushing, breaking and separation are completed simultaneously in the crushing process.
- Hydraulic opening device. Designed with a hydraulic opening device, the crushing chamber can be opened quickly for easy inspection and maintenance.
- Hammer head. Unique hammer head installation method makes it more convenient and quick to replace the hammer head.
- Material crushing fineness can be easily controlled by adjusting air flow velocity, feeding velocity and classifying impeller speed.
- Unique arch-breaking feeding device prevents materials from arching during feeding.
- Special carbide hammer head has high wear resistance, low temperature rise of crushed materials and less water loss.

Why do we need to use ultrafine grinder to produce aquatic feed?
Ultrafine grinding is a very important process in the production of aquatic feed. For some aquatic feed producers, the correct configuration of ultrafine grinding machine can directly improve the quality of aquatic feed pellet.
The main reasons why ultrafine grinders are used in the production of aquatic feed are as follows:
01 Increase the particle size of the particles to improve the utilization rate of feed by aquatic animals.
Aquatic organisms, such as fish, shrimp, crabs, etc., are naturally characterized by short digestive tracts and poor digestion ability. Therefore, the raw materials used to produce aquatic feed require a very low particle size, so that aquatic organisms can improve the digestibility of feed when eating;
02 Increase the particle size of the particles and improve the mixing uniformity of the raw materials.
The particle size of the raw materials directly affects the mixing uniformity. Due to the low food intake of aquatic animals, the feed raw materials are required to achieve a higher mixing uniformity. For example, for the raw materials used to produce shrimp feed, the 60-mesh sieve must contain less than 5%, so a micro-crushing process must be used；
03 It affects the subsequent granulation and extrusion processes, as well as the quality of feed pellets.
For feed made from grains, the finer the grain feed is ground, the more fully its starch particles are gelatinized after steam conditioning, and the more uniform the moisture content, making the quality of the finished feed pellets better.
