High efficiency thickener with central transmission

Our high-rate Thickeners are simple in design and operation with specific benefits for today's producers. After having removed usable materials from the effluent stream, Thickeners recover immediately re-usable process water adjacent to the plant site.

Because process water is available at the point of use, not hundreds of yards away, pump is substantially reduced. The smaller volume of effluent from the Thickener saves real estate - without large settling ponds and process water ponds, usable resources are not covered up. Environmental issues are mitigated by the lack of large ponds; and water consumption is reduced due to elimination of evaporation and percolation losses.

Thickeners use a minimal amount of polymer/chemical in order to drop the solids. Rotating rake arms collect settled sludge and move it toward the center discharge cone. From there the solids are typically pumped out at 35-45% solids to a pond or dewatering device.

In the bottom center of a discharge concentration of the product discharge bucket, pond surrounding the upper ring with the overflow tank. Concentrated in the central pool has a vertical axis, the axis of the cross at the end of a fixed frame rake, rake the following aircraft equipped with a scraper. Rake into a horizontal plane and 8 ° -15 °. Fixed by the vertical axis in the truss on the motor reducer by the middle gear driven rotary. When the vertical axis rotation, the pulp along the truss to the mine shafts into the center of the bowl pool, and to concentrate around the pool flows. Pulp in the settlement of solid particles gradually condensed into the bottom of the pool by the following scraper plane rake scraping into the center of the pool discharge bucket with sand pump. To clarify the above clarificationwater from the Department of the Central Bank out of the overflow tank. In the thickener have been concentrated load or materials, the discharge will fight blockage and rake frame distortion. To prevent this phenomenon, there are signals of safety devices and equipment to upgrade rake frame.

(1)Deaeration cell is provided to avoid bobble on which solid particles may attach and settls as “parachute phenomena”.

(2)The mineral feeding pipe is beneath the liquid surface to provent air to be brought in by feeding.

(3)Inner overflow weir is equipped to let slurry flow on pre-designed route, avoiding “short circuit”.

(4)The pattern of the overflow weir is made into indented shape, eliminating suction phenomena in some part of draining induced by unleveled overflow weir.

Usually used in the following similiar process of gold,silver,copper, lead zinc, molybdenum and so on.

1. Installment:

Thickener installed on the site as a whole.

Keep the spindle, rake concentric with the discharge basket.

Note: The thickener can not run reversely.

2. Trial Run

No-load trial: the run time should be 8 hours, the temperature of motor and transmission parts should not exceed 50 °C.

Load trial: testing time is 8 hours, filled with liquid water.

3. Running

Check whether the discharge pipe and the transmission mechanism works normally, and must be confirmed there is no foreign matter in the pond before start the equipment.

Pay attention to the equipment’s load, the overflow and concentrate’s concentration.

One of the major fault of the equipment is the discharge bucket’s block, many reasons may cause that, such as coarse-grained particles, wood chips, rags falling into, the block is more likely to occur when the sand pump not working. When the block happens, must shut down the gate on the concentrate pump and then feed the high-pressure water into the discharge bucket to solve the block problem. If foreign matters falling into the thickener, should discharge the pulp completely then clean the tank.

Fasten the bolts timely after the operation.

Provide ore dressing experiment,process design and onsite engineering service.
