Abstract
A gypsum washer includes a rotating trommel receiving raw material and a flow of water, and having paddles tilted to reduce impacts of the gypsum passing through the trommel while still providing a washing action. Bentonite separates from the gypsum in the trommel, liquifies, and is released through a mesh screen at the end of the trommel separating from the gypsum. The gypsum is released from the trommel into a water fed trough, scooped from the trough, and released into a storage area. The liquified bentonite is carried by a water flow into one or more settlement tanks, and recovered for use.
Claims14
A gypsum washer comprising:
- a raw material feeder in fluid communication with plumbing to receive circulating water from the plumbing and containing raw gypsum material;
- a rotating trommel in fluid communication with the raw material feeder to receive the raw gypsum material and the circulating water in a slurry from the raw material feeder, the rotating trommel comprising:
- a trommel inlet at a first end, the slurry from the raw material feeder entering the trommel through the trommel inlet;
- paddles inside the trommel;
- and
- a discharge screen at a second end opposite to the trommel inlet;
- at least one bentonite settling tanks in fluid communication with the trommel through the discharge screen to receive liquified bentonite washed from the raw gypsum material and water slurry;
- a water pump in fluid communication with a last one of the at least one bentonite settling tanks to receive circulating water from the at least one bentonite settling tank, the water pump in fluid communication with the plumbing to pump the circulating water into the plumbing;
- and
- a rinser tank receiving washed gypsum and water from the trommel and comprising;
- an auger to advance the washed gypsum through the riser tank;
- and
- conveyer reaching into the rinser tank to extract the washed gypsum and release the washed gypsum outside the riser tank.

A gypsum washer comprising:
- a raw material feeder in fluid communication with plumbing to receive circulating water from the plumbing and containing raw gypsum material;
- a rotating trommel 36 in diameter, 30 feet long, and rotates at between 8 and 15 RPM, the trommel in fluid communication with the raw material feeder to receive the raw gypsum material and the circulating water in a slurry from the raw material feeder, the rotating trommel comprising:
- a trommel inlet at a first end, the slurry from the raw material feeder entering the trommel through the trommel inlet;
- between five and seven paddles about five inches long and tilted away from the rotation of the trommel between 35 and 40 degrees, reaching inside the trommel;
- and
- a discharge screen at a second end opposite to the trommel inlet reaching axially three feet and comprising a 20 mesh screen;
- at least one bentonite settling tanks in fluid communication with the trommel through the discharge screen to receive liquified bentonite washed from the raw gypsum material and water slurry;
- a 25 HP and 300 RPM water pump in fluid communication with a last one of the at least one bentonite settling tanks to receive circulating water from the at least one bentonite settling tank, the water pump in fluid communication with the plumbing configured to pump 125 to 300 gallon per minute and provide about 50 PSI water pressure into the plumbing;
- and
- a rinser tank receiving washed gypsum and water from the trommel and comprising;
- an auger to advance the washed gypsum through the riser tank;
- and
- conveyer reaching into the rinser tank to extract the washed gypsum and release the washed gypsum outside the riser tank.
