The crushing of the laboratory crusher is achieved through the shearing action between the rotary blade, cutting edge, and bottom screen. The sample enters the grinding chamber through the sample inlet funnel, and is quickly crushed under the high-speed shearing of the cutting motor. When the sample size is smaller than the size of the bottom screen aperture, it will enter the collection container to complete the sample crushing.
1、 The principle and classification of laboratory pulverizers
The laboratory crusher mainly consists of a motor, a brake, and a mortar. When the motor starts, it generates high-speed rotational force and then grinds the sample through objects such as a mortar and its built-in steel balls to obtain the desired powder or particles.
According to different working principles and forms, laboratory crushers can be divided into several different types, including pointed mills, vibrating ball mills, star shaped ball mills, and jet shear crushers. The difference between these crushers lies in their grinding methods, material processing capabilities, and final dispersion.
2、 Usage of laboratory crusher
When using a laboratory crusher, we need to pay attention to the following aspects:
Select the appropriate mortar form and mortar material based on the properties and requirements of the sample.
Put the sample that needs to be ground into a mortar and add an appropriate amount of fine sand.
Confirm the sealing of the mortar and start the laboratory crusher.
It is best to regularly observe the sample status in the mortar during the grinding process to check if it meets the expected requirements.
After the sample reaches the required particle size, turn off the laboratory crusher and remove the processed sample.
3、 Performance advantages of laboratory crushers:
1) Three kilowatt powerful motor for efficient driving, ensuring effective grinding of samples;
2) The rotational speed is continuously adjustable from 100-3000rpm, suitable for different samples;
3) The four cutting edges of the grinding chamber shorten the sample grinding cycle, making the sample crushing effect more optimized;
4) Plug and play rotary knives and bottom screens make the grinding chamber easier to clean;
5) The generated heat load is small, making it very suitable for processing heat sensitive samples;
6) Large processing capacity, up to 80L/h sample output;
7) Diversified sample sizes of 0.25-20mm can meet different customer needs;
8) Different materials of rotary knives and screen rings can meet the diverse needs of customers;
9) Digital display ensures the reproducibility of sample crushing results;
10) The sample booster can make it easier for the sample to enter the grinding chamber for crushing;
11) The feeding funnel has a dust-proof design to reduce sample splashing;
12) The chamber door is equipped with a safety lock protection system to ensure the safety of operators;
13) The motor has a braking system and stops quickly.
