Main factors affecting the normal work of the stone machine

When the stone machine is working normally, the rising air velocity of the permeable layer must be equal to the suspension speed of the wheat. If the airflow speed is too large, the material on the surface of the trend screen is easily blown off, and the airflow distribution is uneven, which destroys the automatic classification of the materials, thereby reducing the separation efficiency. If the airflow rate is too small, the wheat will not float and it is easy to climb with stones, which causes the wheat to contain wheat. At the same time, the automatic classification of materials is poor, and wheat varieties are also prone to contain stones, which also reduces the separation efficiency.

1. Tilt: The angle between the stone screen and the horizontal plane is the tilt angle. The size of the dip affects the production and de-stone efficiency of the stone remover, and the effects of the two are contradictory. When the dip is large, it is useful for the decline of wheat flow. However, the trend efficiency will decrease. When the dip is small, the wheat flow is low and the yield is low. At the same time, Shi Zhongyi brought wheat, which increased the grain content of the calf. The inclination of stone machinery is usually 5-9.

2. Angle: This angle refers to the angle between the vibration direction of the screen and the surface of the screen. The vibration of the stone machine is in the form of reciprocating linear vibration. The direction of vibration is slanted, perpendicular to the axis of the vibration motor. The direction of vibration is different from the direction of the vibrating screen and cannot be changed at will. This is the basic condition that the shoulder stone near the surface of the screen can travel along the surface of the screen. Therefore, choosing the right corner facilitates the automatic grading of the material and the rising side of the shoulder stone. However, when the corner is too large, the material easily jumps off the surface of the screen, but it is not conducive to the upward movement of the shoulder stone. The angle of the stone machine is usually 30-35.

3. Amplitude and vibration frequency: The amplitude refers to the amplitude of the vibration of the sieve body. The vibration frequency becomes an operational parameter indicating the vibration speed of the sieve body. When the amplitude is large and the frequency is high, the material moves faster on the screen surface and the automatic classification is stronger. Conducive to separation efficiency and equipment production. However, the amplitude is too large, the frequency is too high, the working surface is violently vibrated, the material is prone to jumping, and the automatic classification of the material is destroyed. Therefore, the separation efficiency is lowered. On the contrary, the movement of the material on the sieve surface is slow, and the material layer becomes thick, which is not conducive to automatic classification of materials. It not only affects the separation efficiency, but also affects the production of the stone remover. The width of the stone remover is usually about 3.5-5 mm. The frequency of the rocker driven by the vibration motor is usually not adjusted, and the frequency of the eccentric rotating stone remover is positively correlated with the rotational speed.
