The jaw crusher BB 50 is a versatile laboratory crusher that allows for the preparation of samples ranging from pebbles and rocks to even harder materials like ores and minerals. This powerful crusher has a feed opening of 45 x 59 mm and is equipped with a 1.1 kW motor. It can deliver a high crushing ratio, with an output size down to 0.5 mm.


1. Easy Operation: The jaw crusher BB 50 is user-friendly, making it simple to operate. The on/off switch, as well as the gap width adjustment, are located on the front panel of the machine for easy access. Additionally, the crushing chamber is equipped with a safety switch that stops the crushing process if the door is opened.

2. Powerful Crushing Performance: The BB 50 is designed for rapid, effective crushing and pre-crushing of medium-hard, hard, brittle, and tough materials. With its high crushing force and adjustable gap width, it can easily crush materials with a hardness up to 3 on the Mohs scale.

3. Minimal Dust Generation: To ensure a cleaner working environment, the BB 50 is equipped with a central lubrication system and a dust extraction unit. These features reduce dust emissions and create a safer workspace for operators.


1. Versatility: The BB 50 is suitable for a wide range of applications, including sample preparation in the laboratory, industrial plants, and production facilities. It can handle various materials such as minerals, rocks, alloys, glass, ceramics, coal, coke, corundum, and more.

2. Reliable Results: The BB 50 delivers consistent and reliable results, thanks to its robust construction and high-quality materials. It is manufactured with hardened steel, which ensures long-term durability and increased wear resistance.

3. Time and Cost Savings: With its efficient design and powerful crushing capabilities, the BB 50 allows for quick and easy sample preparation. This saves time and reduces labor costs, making it an ideal choice for laboratories or facilities that require frequent sample analysis.


1. Start-Up: Before starting the crusher, ensure that the crushing chamber is clean and free from any debris. Connect the power supply and switch on the machine. Adjust the desired gap width using the gap width adjustment knob on the front panel.

2. Loading the Sample: Open the door of the crusher and place the sample inside the crushing chamber. Close the door tightly to prevent any materials from escaping during the crushing process.

3. Crushing Process: Once the sample is loaded, press the start button to initiate the crushing process. The BB 50 will crush the sample until the desired output size is achieved. The crushed material can be collected in a container or further processed for analysis.

In conclusion, the jaw crusher BB 50 is a reliable and versatile crusher that offers numerous benefits in laboratories and industrial facilities. With its powerful crushing performance, easy operation, and minimal dust generation, it simplifies the sample preparation process and delivers consistent and reliable results. Whether you're dealing with minerals, rocks, or other materials, the BB 50 is the perfect choice for efficient and effective crushing operations.
