Hammer Mill Types Explained | Pulva Corporation

Understanding Hammer Mill Types

When it comes to size reduction equipment, hammer mills are among the most versatile machines on the market. These machines are designed to crush, grind, and pulverize a wide range of materials, including concrete, coal, wood, shale, limestone, brick, and plastic. The choice of hammer mill depends primarily on the specific needs of your industry, from coarse to very fine materials.

If you are looking for efficient size reduction machinery, it’s important to understand what a hammer mill is, how it operates, its various types, and how different industries utilize hammer mill pulverizers.

What Is a Hammer Mill?

A hammer mill, often referred to as a pulverizer, is a tool designed to mill, grind, and crush materials. These mills operate by using high-speed hammer blows that shatter and disintegrate the material within. The design and functionality of hammer mills make them suitable for processing materials across various industries, such as:

• Food
• Mining
• Cosmetics
• Recycling
• Chemicals
• Agriculture
• Construction
• Manufacturing
• Pharmaceutical
• Power Generation

How Do Hammer Mills Work?

Inside a hammer mill, a cylindrical steel drum houses the rotating hammers. When material is fed into the drum, these hammers collide with the material, effectively shredding it. Depending on whether screens are used, smaller particles may exit the chamber, while larger particles are retained for further grinding. Variations in speed and hammer design can significantly affect the milling process.

Types of Hammer Mills

There are several types of hammer mills that serve different purposes. Here are some common styles:

1. Lump Breakers

Lump breakers differ in design as they feature fixed hammers rather than swinging ones. They are ideal for reducing the size of materials in a more controlled manner and are often used for dry chemicals, sugar, and cement.

2. Full Circle Screen Mills

These mills include a rotating screen that aids in the rapid evacuation of particles, making them useful for lightweight materials such as grains, sawdust, and spices.

3. Gravity Discharge Mills

Characterized by their swinging hammers in a rectangular steel chamber, these mills utilize gravity for the discharge process and are capable of crushing a wide range of materials, including coal and metals.

4. Horizontal In-Feed Mills

Designed for side loading, this type of hammer mill is used in applications requiring aggressive grinding of heavy particles.

5. Pneumatic Discharge Mills

Similar to gravity discharge mills but enhanced by the integration of air evacuation, these mills are particularly effective for lightweight materials such as biomass and paper.

Utilizations of Hammer Mills

Hammer mills have diverse applications across multiple industries. For instance:

• Grinding food products, such as legumes and nuts.
• Facilitating quick dissolution in pharmaceuticals.
• Reducing fuel sources like wood and biomass.
• Aiding in powder production in chemical industries.
• Facilitating recycling in the automotive sector.
