Beneficiation Mining Technology-Summer Solstice, Rain and Dew, Sun Turning, Love and Gentleness
Today is the summer solstice in the 24 solar terms. The summer solstice is one of the 24 solar terms and the earliest solar term to be determined in the 24 solar terms. The summer solstice usually comes on June 21 or 22. The summer solstice is a solar term in which the day is greater than the night, the sun is abundant, and the rain is abundant. Xu Shuxin's "In the Summer Rain" describes: "In the summer, the wind is blowing and the frogs are singing and the cicadas are hitting the dust. The golden gong is ringing in the blue sky, and the cold rain is like money." After the plum rainy season, summer comes slowly. This is a beautiful season related to summer, floating melon and sinking plum, fan and rattan chair, whispering softly and looking up at the starry sky. We can often hear that the summer solstice is not as hot as three volts, since it is too

Auger drill pipe unlocking considerations
1 Resistance: It is very important to unlock when there is resistance in the spiral drill pipe drilling, because the drill bucket needs to provide resistance to unlock. 2 lifting power head: the function of lifting screw drill pipe power head is to eliminate the gap between the locking section of each drill pipe machine and prevent the drill pipe from being smashed. Another function is to reduce the friction resistance of the lock point of the machine and prepare for unlocking. 3 vibration. Sound: If you carefully identify, you can feel that when you unlock each lock point, you will emit a shock vibration and sound, and with the unlocking sequence, the vibration and sound will be more obvious. 4 lifting load: if the lock is not unlocked, the load when lifting the main roll is obviously increased or cannot be raised. 5 Observation Spiral
