How do we know particles are qualified, although some surface particles can be seen in some cases, but the reason is still the foundation of our content is not very understanding, so how to detect it, the quality of the following two ways can be produced out of straw particle machine particle detection.
(1) take a container, which can contain at least 1 liters of water and weigh its components. Fill the container with particles, scale the weight again, subtract the net weight of the container, and fill the water with the components filled with the particles. The calculated results of the qualified particles should be between 0.6 and 0.7 kg / L, and this value can also be considered as the specific specific gravity of the particles. It is a very important parameter, and it shows whether the pressure is right or not when making the particles. Those unqualified particles, this value will be less than 0.6, they are very simple break and destruction, will happen a lot of fines.
(2) qualified particles mean that water is less than 10%, and from the viewpoint of mechanics, the density is very high and it is very solid. The most simple way to detect the quality of particles: particles in a glass of water, if the sink, prove its density is high enough, the forming pressure was rich enough. However, if the particles float on the surface of the water, it is proved that the density is very low and the quality is very poor. From the point of view of mechanics, its durability is very poor, it is very simple to destroy or turn into fine end.
