Laboratory jaw crusher is used to reduce the size of mineral samples and create uniform particle sizes for analysis. There are several types of laboratory crushers, each for specific applications and materials.
Laboratory Jaw Crusher: The most common type of laboratory crusher, laboratory jaw crusher is ideal for primary crushing of hard and brittle materials with adjustable jaw openings. They come in various sizes and can have adjustable jaw openings to control the output size so they are versatile for all types of bulk material samples. Additionally, micro pulverizers can be used to grind a variety of products to a fine mesh size.
Cone Crushers: For secondary or tertiary crushing, cone crushers are good for processing a wide range of materials including hard, abrasive rocks and ores. They give precise and consistent results so are valuable for detailed analysis.
Roll Crushers: For intermediate crushing of friable materials, roll crushers can be used for primary and secondary crushing. They produce uniform particle sizes and are often used in mineral processing.
Hammer Mills: For soft to medium-hard materials, hammer mills produce a fine output size. They are used in applications where fine grinding is required. The shubh micro pulverizer is particularly versatile in grinding various materials, utilizing high-velocity beaters and specialized feeding mechanisms. These mechanisms often include a specially designed paddle equipped with bearings, which assists in pre-crushing oversized materials before they are conveyed into the grinding chamber.
Disc Mills: For a wide range of materials, from soft to hard, disc mills produce a fine output size. They are versatile and can be used in any laboratory.
Ball Mills: For fine grinding of mineral samples, ball mills use grinding media to crush the sample against the inner wall of the mill. Ball mills are essential for precise and uniform particle sizes in analytical processes.
Each type of laboratory crusher has its own features and applications so you need to choose the right one for your needs.
The design and functionality of laboratory crushers and pulverizers are crucial to their performance. These machines have a CI robust construction with a standardized heavy design, ensuring durability and efficiency in reducing the size of different materials. The grinding chamber, where the material is fed and ground, is engineered to achieve the desired mesh size. The feeding arrangement consists of a specially designed hopper with a sliding valve, allowing a gravity feeding arrangement for lightweight or hygroscopic materials like medicine herbs, spices, and easily grindable substances such as sugar and salt into the grinding chamber. Additionally, screw feeders ensure a uniform feed, and a variable speed arrangement can be provided for precise control. The beaters, forged from hardened material, revolve at high velocity within the grinding chamber, ensuring effective and consistent grinding.
The principle of operation of laboratory crushers and pulverizers is based on particles size reduction through the energy dissipated by rapidly moving beaters. As the rapidly moving beaters rotate at high speed, they impact the particles, causing size reduction. The material is crushed between the high-speed moving beaters and a serrated liner, resulting in a powder. This pulverized fine powder is then pushed through a screen into a collecting bag by the air draft generated from the centrifugal movement of the beaters. The machines can accommodate various feeding arrangements, including gravity feeding, screw feeding, and paddle type feeding, to suit different materials and applications.
Feeding arrangements are critical to the grinding process in pulverizers. There are several types of feeding arrangements, each designed to suit different materials and applications. Screw feeding is a popular choice, providing a uniform way of feeding material into the grinding chamber. This method is particularly effective for materials that require consistent feeding to achieve optimal grinding results. Gravity feeding is ideal for materials that are extremely easy to grind, such as sugar, salt, or carbon. The feeding arrangement consists of a specially designed hopper with a sliding valve, which allows the material to be conveyed into the grinding chamber by gravity. For grinding over-size materials, paddle type feeding is used, while side feeding is suitable for extremely light weight materials. Each type of feeding arrangement ensures that the material is fed into the grinding chamber in a uniform way, enhancing the overall efficiency of the process.
Pulverizer models and specifications vary to meet the specific needs of different applications. One of the most popular models is the Shubh Micro Pulverizer, a compact, low-cost, and highly efficient grinding mill. This model is ideal for small-scale operations and laboratory use, offering excellent performance in reducing material size. Another widely used model is the Model A Pulva Sizer, designed for continuous production work and suitable for both laboratory and pilot plant use. For higher capacity needs, the Model B Pulva Sizer is recommended, with main drive motors ranging from 10 to 25 HP. Each model has its own specifications, including screen area, air passed, hammer tip speed, and power requirements. Choose the right model for your size reduction needs.
The screen and discharge systems in pulverizers are critical for the final particle size of the material. The screen holds the material in the grinding chamber until it is pulverized to the required size, ensuring consistent and precise results. Different types of screens, such as rachet teeth liners or serrated liners, can be used depending on the application. The discharge system collects the fine powder and separates it from the air, preventing dust from escaping. This system may include a cyclone separator or a collecting bag, which efficiently collects the powder. The air draft generated by the centrifugal movement of the beaters helps to collect and discharge the fine powder from the system. Regular cleaning and maintenance of the screen and discharge systems are essential to ensure optimal performance and prevent clogging, making these components critical to the operation of pulverizers.
Using laboratory crushers can be dangerous if proper safety precautions are not followed. Here are some safety tips and troubleshooting advice to ensure safe and efficient operation:
Wear Protective Gear: Always wear safety glasses and gloves when operating a laboratory crusher to protect yourself from hazards from the jaw crushers.
Proper Assembly and Maintenance: Make sure the crusher is properly assembled and maintained before use. Regular maintenance prevents accidents and extends the life of the equipment. The electric motor powering the screw feeders ensures efficient feeding of materials into the grinding chambers, which is crucial for the pulverizing process.
Use the Right Crusher: Use the correct type of crusher for the material you are processing. Using the wrong crusher will be inefficient and hazardous.
Don’t Overload: Don’t overload the crusher, this can cause damage and create hazards. Follow the manufacturer’s guidelines for maximum load capacity.
Regular Inspections: Inspect the crusher regularly for wear and tear, especially the jaw plates and moving parts. Replace worn parts as needed to maintain optimal performance.
Keep It Clean: Keep the crusher clean to prevent contamination and get accurate results. Remove debris and residues after each use.
Common problems with laboratory crushers are clogged or blocked crushing chambers, worn or damaged jaw plates, incorrect gap width adjustment and overloading or underloading. Troubleshooting can be done by consulting the manual, contacting the manufacturer or a qualified technician.
Laboratory crushers and pulverizers need to be maintained and cleaned for their performance and longevity. These machines have a smooth interior of the grinding chamber making them very easy to clean. They can be disassembled for thorough cleaning and reassembled quickly with simple tools. For certain non-sticky products, cleaning can be done by idle running with compressed air which is very effective for fine dry materials. Regular maintenance and cleaning prevents downtime and ensures the machines operate at optimal performance making them a reliable tool in any laboratory.
