ललकाइज़र: विभिन्न उद्योगों का "मैजिक क्रशर"

Nowadays, all industries require the crushing of raw materials to facilitate subsequent production and processing. As an indispensable piece of machinery, the crusher plays a vital role. From food processing to mining, from pharmaceutical manufacturing to building materials production, it has made an indelible contribution.

What is a pulverizer?

A pulverizer is a machine specifically designed to crush large solid materials to a desired size. Depending on the initial size of the material being crushed or pulverized and the desired final fineness, common pulverizer methods include shearing, impact, कुचल, and grinding.

काम के सिद्धांत

Common crushers operate in various ways, including high-speed impact, shearing, कुचल, or grinding.

1. High-speed impact crushing: High-speed rotating components are used to impact the material, causing it to break apart under high-speed impact. This method is suitable for crushing very brittle materials.

A common example is a hammer mill, where the hammers on the rotor rotate at high speed, violently impacting the material entering the crushing chamber.

2. Shearing crushing: Relatively moving blades or toothed discs act like scissors to shear or tear the material. This is often used to crush materials such as straw and rubber. A common example is a knife mill, where rotating blades cut the material into small pieces.

3. Crushing crushing: दो काउंटर-रोटेटिंग रोलर्स या ग्राइंडिंग डिस्क सामग्री पर दबाव डालते हैं, causing it to flatten and crush under the pressure.

This is commonly used to crush hard materials such as millet and ore. Roller crushers are commonly used, where the gap between the rollers is adjusted to control the particle size.

4. Grinding crushing: The material is gradually ground and pulverized by friction and compression between the grinding media and the grinding surface.

It is commonly used for fine processing of Chinese medicinal materials and chemical raw materials. The equipment is an ultrafine pulverizer,

One of which is a ball mill, which allows the material to collide and grind with steel balls in a rotating cylinder to achieve extremely fine particle size.

Working principle and characteristics of the crusher:

1. Hammer mill

This mill primarily uses high-speed hammers to drive the material, causing it to collide violently with each other or with machine components.

The impact of these high-speed collisions shatters the material, ultimately filtering out the desired particle size through a screen.

Hammer mills offer high crushing efficiency and are suitable for crushing brittle materials. The finished product has a relatively uniform particle size, which can be controlled.

They are robust and easy to maintain, but the hammers are susceptible to damage and require regular replacement.

2. Knife mill

This mill uses the shear force generated by the blades to cut, tear, or shred the material. The blades in a knife mill are spiral or disc-shaped.

Driven by a motor, they rotate at high speed, creating a shearing effect on a fixed blade fixed to the housing, shredding the material into fine particles.

Knife mills are suitable for processing tough or fibrous materials, such as plastics, rubber, और भूसा. The material heats up relatively low during the crushing process, minimizing damage to heat-sensitive components.

The blades can be flexibly adjusted to control the finished particle size. Like hammer mills, the blades are susceptible to damage and require regular replacement.

3. रोलर क्रशर

Two or more rollers move in opposite directions at different speeds. Once in the gap between the rollers, the material is squeezed and crushed, crushing it.

The crushed material is then discharged by the rotating rollers.

Roller crushers are suitable for crushing relatively hard materials such as millet. They have high production capacity and low energy consumption, making them suitable for large-scale industrial production and processing.

The gap between the rollers can be adjusted to control the particle size of the finished product, resulting in a well-shaped, minimally over-crushed particle.

4. Ball Mill

Using steel balls contained within the rollers, the rotating drum lifts the balls to a certain height under the influence of centrifugal force and gravity, where they fall, impacting and grinding the material, gradually pulverizing it.

Ultrafine grinding machines such as ball mills can crush materials to the micron level, making them suitable for processing industries with demanding pulverization requirements.

The pulverization process has minimal impact on the chemical properties of the material. They can handle a wide range of material types, but they suffer from low pulverization efficiency and high energy consumption.

Application Scenario

1. Feed Industry

Pulverizers play a key role in the feed production process. They grind various raw materials into appropriate particle sizes for better digestion by animals.

उदाहरण के लिए, they grind grass and straw into the appropriate size for easier feeding by cattle and sheep; they grind feed ingredients to facilitate subsequent pellet production, and so on.

2. Food Industry

In food processing, pulverizers grind grains like wheat and corn into flour for use in pasta. They also grind condiments like star anise and Sichuan peppercorns into powder for easy addition to food and enhance flavor.

In nut processing, granules or powders of varying sizes are used to make nut butters, pastry toppings, and more. Pulverizers can also be used in infant food and health foods to ensure food quality and safety.

3. Pharmaceutical Industry

Because the pharmaceutical industry has extremely high requirements for product quality and safety, pulverizers play a key role in pharmaceutical production. Grinding traditional Chinese medicines into the appropriate particle size facilitates the extraction of active ingredients and the preparation of pharmaceuticals.

In Western medicine production, raw materials are crushed into fine particles or granular powders for use in topical medications, inhalants, and other applications, improving drug utilization and efficacy.

4. रसायन उद्योग

Crushing solid raw materials can improve reaction rates and product quality. उदाहरण के लिए, in the production of plastic pellets, crushing plastic into uniform small particles facilitates plasticization and molding.

Crushing pigment granules, used in the production of pigments, coatings, and other products, ensures uniform color and stability.

5. Recycling Industry

Crushing common household waste, such as kitchen waste and wood scraps, yields a variety of organic raw materials. These raw materials can be sent to industries like feed processing and lumber processing for reuse. Alternatively, metal products like cans can be crushed for metal recycling.

6. Building Materials Industry

Common building materials such as limestone, gypsum, and quartz sand all require crushing in a crusher to meet the production requirements of various building materials. उदाहरण के लिए, in cement production,

Limestone must be crushed before being mixed with other materials to make cement clinker, which then needs to be crushed again before it can be used to make cement. The same goes for bricks and siding.
