How Can We Keep Shale Shaker for Drilling Mud System Work Efficiently?

“Back.” Qhorin mounted his weary garron one more time. “The fire will draw them past, I hope. Come, brother.”
  Jon pulled on his gloves again and raised his hood. Even the horses seemed reluctant to leave the fire. The sun was long gone, and only the cold silver shine of the half-moon remained to light their way over the treacherous ground that lay behind them. He did not know what Qhorin had in mind, but perhaps it was a chance. He hoped so. I do not want to play the oathbreaker, even for good reason.
  They went cautiously, moving as silent as man and horse could move, retracing their steps until they reached the mouth of a narrow defile where an icy little stream emerged from between two mountains. Jon remembered the place. They had watered the horses here before the sun went down.
  “The water’s icing up,” Qhorin observed as he turned aside, “else we’d ride in the streambed. But if we break the ice, they are like to see. Keep close to the cliffs. There’s a crook a half mile on that will hide us.” He rode into the defile. Jon gave one last wistful look to their distant fire, and followed.
  The farther in they went, the closer the cliffs pressed to either side. They followed the moonlit ribbon of stream back toward its source. Icicles bearded its stony banks, but Jon could still hear the sound of rushing water beneath the thin hard crust.
  A great jumble of fallen rock blocked their way partway up, where a section of the cliff face had fallen, but the surefooted little garrons were able to pick their way through. Beyond, the walls pinched in sharply, and the stream led them to the foot of a tall twisting waterfall. The air was full of mist, like the breath of some vast cold beast. The tumbling waters shone silver in the moonlight. Jon looked about in dismay. There is no way out. He and Qhorin might be able to climb the cliffs, but not with the horses. He did not think they would last long afoot.
  “Quickly now,” the Halfhand commanded. The big man on the small horse rode over the ice-slick stones, right into the curtain of water, and vanished. When he did not reappear, Jon put his heels into his horse and went after. His garron did his best to shy away. The falling water slapped at them with frozen fists, and the shock of the cold seemed to stop Jon’s breath.
  Then he was through; drenched and shivering, but through.
  The cleft in the rock was barely large enough for man and horse to pass, but beyond, the walls opened up and the floor turned to soft sand. Jon could feel the spray freezing in his beard. Ghost burst through the waterfall in an angry rush, shook droplets from his fur, sniffed at the darkness suspiciously, then lifted a leg against one rocky wall. Qhorin had already dismounted. Jon did the same. “You knew this place was here.” “When I was no older than you, I heard a brother tell how he followed a shadowcat through these falls.” He unsaddled his horse, removed her bit and bridle, and ran his fingers through her shaggy mane. “There is a way through the heart of the mountain. Come dawn, if they have not found us, we will press on. The first watch is mine, brother.” Qhorin seated himself on the sand, his back to a wall, no more than a vague black shadow in the gloom of the cave. Over the rush of falling waters, Jon heard a soft sound of steel on leather that could only mean that the Halfhand had drawn his sword.
