The grinder has a total of 28 blades on two axles. The unique design and blade diameter of 300 mm per blade ensures the best possible grip – even on big fish. The blades are 20 mm wide and manufactured from stainless steel to ensure durability, even in the toughest conditions. The ScaleAQ pre-grinder is designed for grinding dead fish and other types of fish waste. The blades are designed to handle larger fish without any compromise in terms of quality. By positioning the pre-grinder on top of existing grinding tanks, you can achieve a significant boost to the capacity of your full ensiling system. Acid dosing takes place as usual in the process tank outside the pre-grinder.

  • Capacity of 20 tons per hour
  • Handles all sizes of fish

Acid is added directly to the tank – either from a canister or from an acid dosing system. Remember to check and adjust the pH levels in the grinding tank before transferring to the storage tank.
