Working principle and installation process of specific gravity stone removing machine

The specific gravity stone removal machine is mainly used for impurity removal in grain processing. There are many factors affecting the removal efficiency of the stone removal machine, but the three important factors are: accurate installation of the equipment, standard operation of the equipment and routine maintenance of the equipment.

In the grain processing process, if some impurities are similar to the particle size of rice, it is impossible to separate the rice from the sundries by simply sieving. In the threshing process, if the grain is mixed with gravel of similar size, the crushed stone easily damages the inside of the grain machine under severe vibration. The specific gravity stone removal machine is a new type of grain processing and impurity removal equipment. It mainly uses rice and debris of different densities to achieve separation between the two. The separation effect is good, so it is widely used in the cleaning of large grain processing enterprises, and is in progress.

1. Working principle of gravity stone machine

The specific gravity stone removing machine can be divided into two types, one is a blowing type stone removing machine, and the other is a suction type stone removing machine. When working in a gravity-removing stone remover, rice will enter the screen of the stone remover from the hopper. Under the combined action of the reciprocating vibration of the screen surface and the airflow of a certain intensity, the porosity between the rice grains will increase, and the particles of different densities will also be separated. Among them, the denser gravel will stay at the bottom of the screen surface and slowly crawl into the gravel collection port as the screen surface reciprocates. The less dense rice is driven by airflow and continuous feeding. Gradually enter the rice export

2, the specific gravity stone machine installation process optimization

In the process of gravity stone machine operation, the fan is an indispensable equipment. When the rice enters the screen surface, it needs to rely on the fan to blow the separation of the gravel and the rice. Therefore, the wind speed and wind pressure setting of the fan will be directly Affect the specific gravity of the stone removal machine. In this regard, each specific gravity stone machine must be equipped with a special fan, and adjust the wind pressure and wind speed of the fan according to the actual situation, so that the wind supply of the fan can meet the requirements of the specific gravity removal machine.
