A sand dredge sucks the sand off the bottom of the river. The one we built has a big Cat running a 12 inch intake 10 inch discharge pekor gravel pump. You move around the river with cables going to both sides of the river. Whenches ran by hydro. The sand and water and what other trash it picks up travel threw 10 inch pipe ( about 2000 feet ) to a tank the sand and water go three a screen and the trash hits the ground. We sell the sand to Concrete company's Years ago we was selling over a 1000 tons a week. Past five years it has dropped off so much it just was not worth keeping this old thing running. So we cut it it and sold the scrap. Good thing is the pump is worth more now for parts then it cost new 20 years ago.What is a sand dredge or what are you dredging sand for.
