In the pre-treatment of laboratory samples, jaw crushers are an efficient and convenient device widely used in fields such as minerals, ceramics, pharmaceuticals, etc. This article will introduce the basic principle, main structure, usage method, and advantages of the laboratory jaw crusher. 1、 Basic Principles
The jaw crusher uses mechanical force to crush the sample. The principle is to fix one end of the jaw plate and move the other end along the rack guide rail, forming a closed crushing stroke to achieve sample crushing.
2、 Main structure
It mainly consists of a rack, jaw plate, adjustment device, and safety protection device. The rack is the supporting structure of the entire equipment, and one end of the jaw plate is connected to the adjustment device through a shaft, which can move along the rack guide rail to form a crushing stroke. The adjustment device can adjust the size of the crushing stroke to control the degree of sample crushing. The safety protection device mainly includes photoelectric protection and mechanical protection to ensure safety during operation.
3、 Usage
The main steps for using a laboratory jaw crusher are as follows:
Sample preparation: Clean the sample that needs to be crushed to remove surface impurities and pollutants.
Sample placement: Place the prepared sample into the crushing chamber, ensuring that the sample is located between the jaw plates.
Start the equipment: Turn on the jaw crusher, adjust the spacing between the jaw plates, and control the size of the crushing stroke.
Crushed sample: During the repeated movement of the jaw plate, the sample is gradually broken into the required fineness.
Collect samples: After crushing, collect the crushed samples for subsequent analysis.
4、 Advantages
The laboratory jaw crusher has the following advantages:
Efficient: The jaw crusher has high crushing efficiency and can quickly break large samples into small particles.
Convenient: The jaw crusher is simple to operate. Just put the sample into the equipment and adjust the jaw plate spacing to complete crushing.
Adjustable: The degree of sample fragmentation can be controlled by adjusting the spacing between the jaw plates to meet different experimental needs.
Safety: The jaw crusher has a safety protection device that can effectively avoid accidental injuries during operation.
Durable: The components of the jaw crusher are made of wear-resistant materials, with a long service life and low maintenance costs.
In short, the laboratory jaw crusher is an efficient and convenient sample pretreatment tool widely used in fields such as minerals, ceramics, pharmaceuticals, etc. By understanding its basic principles, main structure, usage methods, and advantages, we can better utilize it for experimental operations, improve the efficiency and quality of sample pretreatment.
