Types and Characteristics of Grinding Equipment: Comparative

Milling is an essential process in the grain, mineral and other material processing industry. Different types of mills are used to achieve different objectives, such as particle size, homogeneity and quality of the final product. We will analyze the main types and types of milling equipment, addressing the advantages and disadvantages of each one.

hammer mill

O hammer mill is a piece of equipment that uses hammers attached to a rotating shaft to crush materials into smaller particles. It is generally used in the grinding of grains, food products, animal feed, minerals and other fibrous materials.

The Idugel Group has the largest hammer mill for corn available in the country, in addition to having equipment with differentials that add greater performance and anti-explosion safety to this equipment, through the combination of industrial aspiration technologies.

Benefits:

• Efficient in reducing particle size
• Flexibility in granulometry adjustment
• Easy maintenance and hammer replacement
• low initial investment

Disadvantages:

• Greater wear on parts due to friction between the hammers and the material
• Higher energy consumption compared to other types of mills
• Dust production and noise during the grinding process

Roller Mill or Roller Bank

The roller mill, also known as cylinder bank, uses two or more parallel and horizontal cylinders to grind materials. It is widely used in the food industry, especially in the grinding of cereals and flour.

Through its Chromium, Titanium and Platinum lines, the Idugel Group has several options for roller mills and cylinder banks, from versions focused on cost-benefit to advanced solutions with energy regeneration.

Benefits:

• High production capacity
• Lower energy consumption compared to the hammer mill
• Uniformity in product granulometry
• Lower heat and dust generation
• Lower fines generation, variable configuration

Disadvantages:

• Higher initial investment
• Need for frequent adjustment of rollers

stone mill

O stone mill, also known as a disc mill, uses two flat, circular stones to grind materials. It is one of the oldest types of mills and is currently used in grinding food products and producing wholemeal flours.

The Idugel Group, in partnership with the Danish group United Milling Systems, has a portfolio of more than 80% of grinding stones supplied worldwide, with advanced technology.

Benefits:

• Slow and uniform grinding, preserving the nutritional properties of the grains
• Lower heat and dust production
• Low energy consumption
• Preserves the nutritional characteristics of the ground grain

Disadvantages:

• Low production capacity
• Wear of stones over time
• Need for adjustment of stones and periodic cleaning

Centrifugal Mill

O centrifugal mill uses centrifugal force to grind materials. The materials are fed into the center of the mill and thrown against the internal walls, where grinding takes place. It is used in the chemical, pharmaceutical and mining industries.

The Idugel Group develops rotors of special grinding to meet the most diverse types of applications, according to the granulometry demand of the final product.

Benefits:

• High production capacity
• Grinding of hard and abrasive materials
• Efficient in reducing particle size
• Flexibility in granulometry adjustment

Disadvantages:

• Higher energy consumption compared to other types of mills
• Wear of parts due to friction between the material and the internal walls
• Noise and heat generation during the grinding process

Comparison between types of grinding equipment:

When choosing the right type of mill, it is necessary to take into account the application, the desired particle size, the type of material to be ground and the production capacity.

The hammer mill is ideal for grinding fibrous and highly hard materials, being an option with low initial cost and easy maintenance.

The roller mill or cylinder bench is more suitable for grinding cereals and flours, offering greater uniformity in the final product and lower energy consumption.

The stone mill is ideal for grinding grains and producing wholemeal flours, preserving the nutritional properties of the materials and generating less heat and dust.

The centrifugal mill is suitable for grinding hard and abrasive materials, being an option with high production capacity and efficiency in reducing particle size.
