Know Basic Milling Technology and the Evolution of Hammer Mills

 In applications requiring particle reduction for material processing, industrial hammer mills are used. The basic hammer mill working concept is constant despite variations in machine designs: uniform size reduction of aggregate raw material is accomplished by repeatedly striking hammers mounted on a rotating shaft. Hammer mill can efficiently grind, shred, shatter, or pulverize any raw material to the desired conclusion upon impact, whether it be titanium or coffee beans.

 

Basic Milling Technology and the Evolution of Hammer Mills

Hammer mills have been used for hundreds of years to crush coarse materials into a fine powder, most notably grains like wheat or minerals like salt. This is known as basic milling technology. The hammer mill changed from a simple tool for crushing stone to an advanced machine utilized for material processing by many industries with the development of industrial milling over the previous two centuries.

 

The core components of the hammer grinder have not changed after numerous design iterations. On a revolving shaft, a variety of hammers are supported between rigid plates. The hammers, which can be mounted horizontally or vertically, freely swing around the shaft to crush the aggregate material that is fed into the pulverizing chamber from above. Then, as it passes between the milling components (mantle and concaves), it is gradually crushed until it ultimately leaves the pulverizing chamber at the bottom under the effect of gravity.

 

The raw material is reduced inside the grinding housing not only by the repetitive hammer strikes but also by the walls of the grinding chamber and the impact of a particle on a particle. Once the material has been shrunk to the desired size, it is discharged through specially crafted steel grates or metal screens. Gravity makes it simple for heavier and more freely flowing materials to leave the apparatus. Pneumatic suction is typically used to discharge lower-density materials. No material can leave the mill until it has gone through the openings in the steel grate or metal screen. Consistency and uniform particle size are therefore guaranteed. 

 

The size of the housing, the rotor, the size of the hammers, the type of screen or grate, and the rotational speed are other variables in the design variation of hammer mills. For instance, a rotor's greater RPMs will raise the hammers' centrifugal force, which will increase the force of each strike on the material. The desired particle reduction of the raw material supplied into the housing is accomplished by a combination of the RPMs and energy released by centrifugal force.

 

Needs for Hammer Mill Capacity

Any hammer mill application's capacity requirements are related to the raw material being processed. The characteristics and physical makeup of the raw material weigh heavily on the size and type of machine that is required to process it, both literally and figuratively. Cake mix production does not require the same hammering equipment as coal processing. 

 

High capacity and power efficiency are essential requirements for any machine in today's current industrial hammer mill designs. For all industrial and food processing applications, however, obtaining uniform particle size is crucial. The advancement of screen technology has improved machine productivity and uniform end-product quality. Regard to the Full-Screen design system, in particular, evenly distributes raw material throughout the whole surface area of the screen for hammering and grinding, boosting throughput capacity without raising power needs.

 

Hammer Mill Design Customization for Your Use

The design's simplicity allows for customization in the processing of a wide variety of materials used by numerous industries. Hammer mills are used by the food, mineral, pulp & paper, chemical, and agricultural industries to process their products. The raw material can be efficiently reduced by hammer mills to the required sizes, from medium-sized particles to ultra-fine particles. Hammer mills are essential to industrial production, whether they are used to produce food pellets for livestock feed, sugar, spice, mineral granules, powders for pharmaceuticals, chemicals, meals, or flour.

 

The hammer mill, which is the most well-known and popular particle reduction tool, offers answers for difficult raw material processing problems. In order to provide businesses with cutting-edge milling solutions and a guaranteed return on investment in equipment, Prater Industries overcomes these challenges through the use of cutting-edge technological applications, creative design, a thorough understanding of industry requirements, and industry expertise.

What Exactly Is a Hammer Mill Machine?

 A Hammer Mill machine is a type of crusher that uses repeated blows of a hammer to crush material into smaller particles. The aggregate material can be corn stalks, rocks, corn, coal, gypsum, etc.

The Hammer Mill With Cyclone has a large diameter and a dynamically fully balanced rotor. The purpose of using a hammer mill with a cyclone is to grind dried waste materials such as agricultural waste and residuals from factories and mills. Hammer mills are generally made with cast iron and fitted onto a spindle shaft. The machine includes some beaters, which rotate at very high speed in the grinding chamber.

 Following are some benefits of a hammer mill with a Cyclone -

Material Size Reduction: A hammer mill with a cyclone is very useful for material size reduction. Some materials are very hard and cannot be ground in a normal hammer mill. So a hammer mill with a cyclone makes the task very easy. It is very helpful in grinding seeds, ground nuts, etc.

Consumes Very Little Electricity Power: A hammer mill with a cyclone consumes very little electricity as compared to a normal grinding machine. As hammer mills with cyclones grind things very fast and take less time, it is obvious that they consume very little power from electricity. Less electricity consumption means lower costs, which will allow you to grind products at a lower cost. Low cost means more profit.

Available in Various Capacities And Sizes: A hammer mill with a cyclone is typically available in a variety of sizes and capacities. The large industries prefer hammer mills with large capacities and sizes, while the small ones can be used for small-scale grinding in farms. So if there is only a small need for a hammer mill, the user doesn’t have to buy a big one.

Less Maintenance: Any type of machine requires maintenance, which includes rotation or moving parts. It is important to ensure that every part performs at its maximum capacity. However, because it includes a cyclone, it requires less maintenance than a standard hammer mill. It just needs the cleaning of hammer rods, wears plates, and bearings.

Save Human Labour - It helps to provide very efficient grinding in the shortest possible time, which helps to save both human labor and time. If the grinding process has to be done by humans, it will take hours to grind only one kilogram of material. But if it has to be done by hammer mill, then it is only a matter of seconds. A hammer mill can grind tonnes of material in an hour.

As a result, it is a time-saving machine that also contributes to increased output. 

Conclusion  

Hammer mill with cyclones are used in many industries for different purposes such as milling grain, fruit juice production, ethanol plants, shredding paper, waste management, etc. In farms, these machines are also used to mill grain into a coarse flour. Hammer mills come with automatic controls, which make them very easy to use. These types of machines increase the output by a large quantity, thus saving more time and energy.

Wood Chipper Vs Shredder: Which Is Better?

Wood chippers and wood shredders are sizable, compact, and strong outdoor power tools that are specially made to minimize the volume of wood debris to facilitate disposal. Many individuals will concur that dead tree trunks and branches wind up being burdensome for homes and job sites, acting as obstructions that give the area they sit upon absolutely no benefits. 

Shredders and chippers for wood can be used in this situation. They chop or crush them into chips, creating enough mulch for your garden, a cushioned surface for the playground, or even a source of renewable energy. 

Wood Chipper: 

A wood chipper is a sizable outdoor power instrument used mostly for breaking down huge pieces of wood, including trees and bushes, logs, roots, or sticks, into smaller, more manageable wood chips. These gadgets are frequently highly transportable and put on frames and wheels that may be towed behind a truck or van. A big hopper into which the wood is fed, a long chute used as a part of the disposal system to release the chips, and a gas engine as their main source of power are some of its features. 

This machine has a huge flywheel inside with a blade or blades mounted to one side. This fast-spinning wheel chops the wood into smaller chips. Simply chipping wood, or more poetically, reducing huge logs of wood to smaller, more refined wood chips, is the basic function of a wood chipper grinder as a machine. 

It may be difficult for some people to imagine, but this machine isn't staffed with little lumberjacks rather, its interior is stocked with more advanced technology. The hopper, chipper, collar, chute, and collection bin are just a few of the components and characteristics that make up this equipment. 

Wood Shredder: 

With a few minor physical variations, wood shredders could only resemble wood chippers in size. The wood materials are fed into the wood shredders through a chute, and then the material is discharged out of the opening. Internally, flails, also known as slightly blunt blades, are employed in wood shredders to break down or reduce small pieces of organic material. 

You’ll immediately notice a few things about wood shredders, such as the fact that they feature two hoppers rather than just one and don’t have the same long ejection chute as a wood chipper. Shredders for wood have the distinction of allowing the user to select the output size. These stationary blades crush and shred the wood, resulting in smaller bits that can be composted or used as mulch. Larger branches, however, cannot be handled by wood shredders due to the limited engine size and bluntness of the flail. 

Conclusion: 

The manner in which the wood chipper and shredder reduce or break down natural material is the primary distinction between them. Using a wood chipper is the ideal way to handle and then reduce huge branches and pieces of wood into smaller chips. 

The material is crushed or pulled apart by a wood shredder, which uses the material’s blunt edges to do so, leaving it in a condition that is suitable for composting. Despite the fact that many people like to use these terms synonymously, chippers can handle large and whole materials while shredders are typically used to crush soft and small materials like leaves and other types of debris.

In this blog, you will read about the working process, types, and applications of hammer mills so that you can easily choose an ideal hammer mill according to your needs.

Working Process of a Hammer Mill:

The way a hammer mill works is straightforward. Hammers installed on a horizontal or vertical shaft are housed inside a cylindrical steel drum. When the drum rotates, the hammers blow on the material that has been fed into it. The ground material is broken into little pieces and forced through screens that are positioned inside the drum in the correct sizes. There are hammer mills without screens that employ air to distinguish between large and small-sized particles.

These hammer mills are used to crush materials in the primary, secondary, or tertiary stages. Depending on the application, hammer mills come in a variety of sizes and power capacities. Electric motors with a capacity of more than 2000 to 5000 horsepower are used in industrial hammer mills.

Types of Hammer Mills:

Gravity Discharge Industrial Hammer Mills: 

The swinging hammers in these hammer mills are fixed to a shaft. Both hammering application and particle-on-particle force are used to reduce the particle size. These mills are known as bottom discharge or gravity discharge hammer mills because the discharge occurs from the bottom and is subject to gravity. These mills are used to crush materials such as ceramics, dry chemicals, and glass.

Full Circle Screen Hammer Mills: 

A 300-degree rotating screen on these industrial hammers enhances particulate evacuation. It works well for lightweight components that don't need to be initially ground. Spices, grasses, and other materials are hammered in these mills.

Horizontal in-feed Hammer mills: 

These mills are used to grind heavy particles because of their aggressive operation. These hammer mills have trim scrap grinders and pallet grinders for performing tough industrial grinding.

Lump Breakers: 

Lump Breaker differs significantly from comparable hammer mills in both design and functionality. This type has a small fixed hammer structure on the shaft rather than swinging hammers. This hammer mill's objective is to smooth out the powder or paste, not to diminish the particle size. Comb refers to the hammer construction on the shaft. To reach the desired particle size, the particles are made to pass through the comb.

Applications of Hammer Mills

Production of Powder: 

Various types of hammer mills are employed in the pharmaceutical and chemical industries to produce the powder. A middle-grade powder is produced after all necessary materials are crushed in hammer mills. When employing hammer mills, grain size can be almost precisely measured. These mills are only limited because no sticky materials can be pounded since they might adhere to the perforated screen.

Grinding of Legumes, Grains, & Food Products: 

In the food processing sectors, several kinds of legumes are ground using hammer mills. They primarily function as grinders for soy, nutshells, groundnuts, and various kinds of beans. Hard nutshells are removed using hammer mills that use gentle hammer blows.

Material Size Reduction: 

Hammer mills are used in the pharmaceutical industry to micronize materials. The dosage of the therapeutic grains must precisely fit inside the capsule packing. As a result, before packaging, the grains are ground into a fine powder using hammer mills.
