Laboratory Crushers and Pulverizers: A Guide
Whether in a mine or a materials testing laboratory, crushers and pulverizers are must haves for the mining industry. Pulverizers and lab crushers from Certified Material Testing Products can handle anything. Our equipment comes in various feed capacities and jaw sizes so you can find the exact one for your needs.
Laboratory Jaw Crushers and Pulverizers
Jaw style lab crushers and pulverizers use compressive force to break down materials between two dies or “jaws”. The adjustable jaw opening is key to controlling the size of the crushed output so you can get precise sizing in all crushing applications. Laboratory jaw crushers come in various models and specs, sizes, capacities, materials of construction and features for material reduction in laboratory. Find jaw width sizes for jaw crushers to fit whatever you will be processing in your lab. Have questions about jaw crushers? Contact Certified Material Testing Products today.
We recommend the popular Mini-Jaw Crusher for most lab needs. The Mini-Jaw Crusher has reversible jaw plates made of manganese steel for added durability and performance in batch and continuous use.
Types of Laboratory Jaw Crusher
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.
-
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.
-
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.
Laboratory Crusher Safety and Troubleshooting
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.
-
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.
