Hammer Mill

overview

The hammer mill, also know as hammer crusher, is a versatile and efficient grinding device used in various industries for crushing, grinding, and pulverizing a wide range of materials. The hammer mill is a vital equipment in the charcoal briquette production process, grinding raw materials into desirable size for further briquetting.

Introduction

Role of Hammer Mill in Charcoal Briquette Production Line

The hammer mill is used to grind and pulverize raw materials (such as wood chips, agricultural residues, and biomass) into smaller, uniform particles, which is essential for making high-quality charcoal briquettes in charcoal production line. The fine particles allow for better compaction and binding during the briquette formation process.

The Structure of Hammer Mill

Feed Hopper: The starting point where raw materials are fed into the mill. Designed to ensure a controlled and consistent flow of materials into the pulverizing room.

Pulverizing room includes four parts:

Rotator: Central part that rotates at high speed. Drives the hammers to move and impact the materials.

Hammers: Attached to the rotator and made up of stainless steel. Swing at high speeds to crush the materials upon impact.

Screener: Mesh or perforated sheet that filters the particles. Ensures only particles of the desired size pass through.

Toothed Plates: Fixed around the perimeter of the pulverizing room. Provides an additional surface for materials to bounce against and get further pulverized.

Discharge outlet: Below the hammer mill to discharge the pulverized materials out of the pulverizing room.

Working Principle of Hammer Mill

Feeding: Wood materials are fed into the feed hopper. They fall into the pulverizing room due to gravity.

Pulverizing: In the pulverizing room, the high-speed rotating hammers strike the wood materials. The materials are bounced between the hammers and toothed plates. This repeated process of beating, collision, and friction gradually breaks down the materials. The materials are also ground between the hammers and the screener. The process continues until the particles are small enough to pass through the screener.

Discharging: Finally, after crushed materials of desirable size passes the screen, they are discharged through the outlet for further processing.

Finished Product

Uniform Particle Size: The hammer mill produces particles of uniform size, which is essential for ensuring consistent quality in subsequent processing steps.

Fineness: The crushed materials are typically reduced to fine powders or small granules, which are easier to handle and process.

Adjustable Fineness: By changing the screen size, the fineness of the output can be controlled, allowing for customization based on specific requirements.

The features of materials crushed by a hammer mill: uniform particle size, reduced size and better mixing properties. These characteristics contribute to more efficient processing, better product quality.

Features of Hammer Mill

  • 1. Efficient: Designed for high-speed operation, ensuring quick and efficient processing.
  • 2. Versatile: Capable of grinding a variety of materials with different properties, including fibrous, brittle, and hard materials.
  • 3. Durable: Components like hammers and toothed plates are made of high-strength alloys for longevity to withstand heavy-duty use.
  • 4. Simple Design: Straightforward construction makes it easy to operate and maintain. Fewer components result in less downtime and easier troubleshooting.
  • 5. Customized: The hammer mill can be tailored to specific needs with different screen sizes, hammers, and configurations. Adjustable screens allow for flexibility in achieving desired particle size.

Application of Hammer Mill

Charcoal Briquette Production: The hammer mill can grind wood, agricultural residues, and other biomass into fine particles for making charcoal briquettes.

Biomass Fuel: The hammer mill can convert agricultural and forestry residues into fine particles for use as biomass fuel.

Animal Feed Production: Hammer mill is used to grind hay, straw, and grains, such as corn, wheat, and barley, into coarse or fine powder for animal feed.

Grain Milling: Processing of grains into flour or meal for baking and cooking.

Mineral Grinding: Crushing and grinding of minerals and chemicals into fine powders for use in various chemical processes.

Concrete Production: Grinding of materials like limestone and gypsum to produce cement.

E-Waste Recycling: Crushing electronic waste into smaller pieces for further processing and material recovery.
