1. Introduction to Poultry Feed Crusher

A Poultry Feed Crusher—also known as a feed grinder or hammer mill—is a key piece of equipment widely used in poultry feed processing. Its primary function is to crush raw materials into fine particles, ensuring better digestibility, uniform mixing, and improved feed pellet quality. The machine is used to process materials such as corn, wheat, soybean meal, sorghum, rice husks, cassava, and various grains required for broilers, layers, breeders, ducks, and other poultry species.

As modern poultry farming expands and feed quality requirements increase, the poultry feed crusher has become essential for feed mills, farms, and agricultural processing industries. High-efficiency crushing improves feed conversion rates (FCR), optimizes nutritional absorption, and enhances the productivity and health of poultry.

This article provides a detailed 3000-word guide covering structure, parameters, features, advantages, applications, operation, and FAQs to help users select the right poultry feed crusher and optimize feed production.

2. Working Principle of Poultry Feed Crusher

The poultry feed crusher works based on impact, shearing, and friction forces. When raw materials enter the crushing chamber:

1. A high-speed rotor drives rotating hammers.

2. The hammers strike the materials, breaking them into smaller particles.

3. The particles are further reduced through collisions against the liner plates.

4. Once the particle size is small enough, the powder passes through the sieve.

5. Fine particles exit as finished feed powder.

Key mechanical principles include:

• High-speed rotation (2500–4000 rpm) generates enough impact force to crush hard grains.

• Sieve mesh size determines final particle size.

• Hammer arrangement influences crushing efficiency and uniformity.

• Airflow inside the chamber helps discharge powder smoothly.
