Advantages of Hammer Crusher Machine

High crushing ratio: Generally, the crushing ratio of hammer crushers can reach 10 to 25, and in some cases, it can be as high as 50. This means they can effectively reduce large pieces of material into smaller particles in a single crushing process, improving work efficiency and reducing the need for multiple crushing stages.

High production capacity: Hammer crushers are designed to handle a large amount of material in a short period of time, making them suitable for high-volume production applications. Their high-speed rotation of the rotor and the impact force of the hammers enable efficient crushing, resulting in high output.

Uniform product size: The crushing action of hammer crushers ensures that the resulting product has a relatively uniform particle size distribution. This is beneficial for subsequent processing steps such as grinding, mixing, and separation, as it provides a more consistent feed material.

Simple structure and low cost: The structure of hammer crushers is relatively simple, consisting of a rotor, hammers, a casing, and a screening mechanism (in some cases). This simplicity leads to lower manufacturing and maintenance costs compared to some other types of crushers, such as cone crushers or gyratory crushers, which have more complex structures and require more expensive components.

Versatility: Hammer crushers can handle a wide variety of materials, including soft and medium-hard materials such as limestone, coal, gypsum, and shale. They are also suitable for crushing materials with different moisture contents, although the moisture content should generally not exceed a certain limit (usually around 10%).

Selective crushing: Hammer crushers have the ability to selectively crush materials based on their density. Materials with higher density are more likely to be crushed into smaller particles, while those with lower density may remain relatively larger. This selective crushing can be useful in separating different components of a material or in achieving a specific particle size distribution.

Light weight and easy installation: Due to their relatively simple structure and lightweight design, hammer crushers are easier to install and transport compared to some heavier and more complex crushers. This makes them suitable for use in various locations, including small-scale mining operations or construction sites where mobility is important.

Types of Hammer Mills

Horizontal Hammer Crushers

As the name suggests, horizontal hammer crushers have a horizontal orientation. Horizontal hammers are mounted on a rotor. The rotor is located at the center of the equipment, and the hammers swing from it. Horizontal hammer crushers generally find applications in crushing limestone, coal, and gypsum.

Vertical Hammer Crushers

Unlike the horizontal type, vertical crushers have hammer mills that are oriented vertically. This type of hammer crusher is more efficient than the horizontal type. It also has a smaller footprint and requires less space on the factory floor. The vertical design allows the hammers to be mounted on a vertical rotor, as opposed to horizontal rotors, which sometimes lack efficient rock shredder generator qualities.

Single Stage Hammer Crushers

A single-stage hammer crusher is a new type of equipment that needs to be revised in the crushing industry. Unlike other types, the single-stage crusher only has one rotor and runs one crushing stage. This simplifies the crushing process and eliminates the need for multi-stage crushers. Single-stage crushers are suitable for using companies to manufacture cement or process intermediate minerals.

Dual Stage Hammer Crushers

Also called a two-stage hammer shredder, this device contains two rotors to perform double crushing on materials. The first rotor crushes large particles, and the second refines the material into smaller sizes. This makes two-stage hammer crushers ideal for fine grinding and particle size reduction.

Pocket Hammer Crushers

Once called the pocket breaker, a pocket hammer features a small and compact design that allows it to break rocks' vertical and horizontal pockets. Its small size makes it portable, although it lacks the power of large hammer crushers.

Used of Hammer Crusher Machine

Mining Industry

The mining industry primarily uses crushers to break down valuable ores into manageable sizes for further extraction processes. Hammer crushers are often used to crush soft to medium-hard minerals and ores like gypsum, coal, and limestone commonly found in quarries. Dual-stage crushers are particularly useful for mining companies that need to grind ores to a fine powder for processes like leaching or flotation.

Cement Production

Cement manufacturers use hammer crushers to break large blocks of limestone or other materials into smaller pieces that can be fed into kilns. A single-stage hammer crusher is often utilized for this purpose as it efficiently handles large materials and produces a relatively uniform size output.

Aggregates and Construction Materials

The aggregates industry uses a hammer crusher to produce crushed stone used in roadways, buildings, and other construction projects. By breaking down materials like granite, basalt, or quartzite into smaller sizes, these machines provide the raw material used in concrete production. Two-stage hammer crushers, with their fine grinding capabilities, are also used to produce manufactured sand, a crucial component for modern construction.

Industrial Waste Recycling

Recycling companies use hammer crushers to process a wide range of materials, including metals, plastics, and electronic waste. These machines help break down big objects like car parts, appliances, or batteries into smaller pieces that are easier to sort and recycle. Two-stage crushers are particularly useful for separating metals from insulation or other waste materials.

Energy Industry

In the energy sector, hammer mills are used to crush biomass materials like wood chips, straw, or agricultural residue. This size reduction helps optimize materials for gasification, combustion, or other energy production processes. Such is the versatility of hammer crushers that the two-stage models can also provide finely ground materials ideal for pelleter or briquetting machines.

Hammer Crusher Structure & Parts

Shell

The shell is composed of the lower body, the upper rear cover, the left and the right side walls. Each part is connected by bolts. A feeding port is set on the upper part. The inner part of the shell is made of manganese steel, which can be replaced after being worn. The lower body is welded by steel plates in order to place the bearing to support the rotor on both sides of the lower body. A shaft seal device is arranged between the casing and the shaft to prevent ash leakage.

Rotor

The crusher rotor is composed of main shaft, hammer holder, and pin shaft. The hammer is suspended on the hammer holder in eight rows by the pin shaft. In order to prevent the axial movement of the hammer frame and the hammer head, both ends of the hammer frame are fixed with a compression disc and a lock nut. In addition, in order to make the rotor store a certain amount of kinetic energy in motion, a flywheel or large pulley should be installed at one end of the main shaft.

Main Shaft

The main shaft is the main part supporting the rotor, which needs to bear the mass and impact force from the rotor and hammer head in the process of operation, so its material must have high strength and toughness.

Hammer Holder

The hammer holder is used to hang the hammer heads. Although it does not directly participate in the process of crushing materials, it is still subject to the impact and friction of ore and wears, so it should be made of materials with good wear resistance.

Hammer

The hammer heads are the core part of a hammer crusher. The weight, shape, and material of hammer heads affect the production capacity of the crusher significantly.

Grate

The arrangement of grate bars of the hammer crusher is a circular arc that is perpendicular to the moving direction of hammerhead and has a certain clearance with the rotary radius of the rotor. The material smaller than the gap between grate bars can pass through the gap, and the material larger than the gap will be continuously impacted, ground and broken by the hammers until it can pass through the gap. Due to the impact of hard materials and metal blocks, the grate is easy to bend and break, so it needs to be inspected and replaced frequently.

Lining Plate

The lining plate is installed inside the shell to protect it from the ore. The lining plate is cast of high manganese steel, the same material used for the grate bar and hammer. The lining plate can be replaced when it is seriously worn to ensure product quality.

Hammer Crusher Working Principle

Material Feeding: The material is fed into the hammer mill through a feed hopper. This can be done manually or through an automated feeding system, depending on the specific application.

High-Speed Rotation: Once the material is inside the hammer mill, the hammers attached to the rotor start rotating at high speed. The centrifugal force generated by the rotating hammers causes them to strike the material with great impact.

Impact and Pulverization: The repeated impact of the hammers on the material results in its crushing and pulverization. The high-speed rotation and the design of the hammers ensure efficient and effective pulverization of the material.

Screening and Particle Size Control: After being crushed, the material passes through a screen or grates located at the bottom of the hammer mill. This screen or grates have specific openings that allow particles of the desired size to pass through, while larger particles are retained and continue to be crushed by the hammers.

Collection of Final Product: The final product, consisting of particles of the desired size, is collected at the bottom of the hammer mill. It can be collected in a container or conveyed to another part of the production process for further processing or packaging.

Hammer Crusher Maintenance

Sufficient lubrication will prolong the service life of the hammer crusher. Operators should add lubricating oil to the bearing and other wearing parts and change the oil every three months.

Mobile inspection and routine maintenance are necessary. The operator should often check the bearing to make sure that the temperature does not exceed 70℃ and check whether the bolt is loose and the lubrication system is working properly.
