NZSG-15 Efficient Thickener

Operation Instruction

Ⅰ.Equipment Application:

This machine is a single-deck high-performance thickener used in the process of wet concentrate dehydration, usually is used in the first phase of the process----dehydration, usually can get concentration with water content 30-60%, the equipment usually is located between the concentration and filtering devices, sometimes can also be used as dehydration unit.

Equipped with deaerating tank to prevent solid particles from adhering to the bubbles, and to subside like "parachute '. The feed tube is located below the liquid surface to avoid air blending with the pulp, and jagged overflow weir reducing the chance of uneven suction phenomenon.

Ⅲ、Equipment structure and working principle

1. The gears  2. Girder  3. Railing  4. Feeding column 5. Deaerating tank  6. Rake  7. Funnel   8.Lifting part 9. The shell

In the bottom center of the tank located a discharge bucket, around the pond there is a  overflow tank. A vertical axis is situated in the tank's center, on the axis' end fixed a cross rake, under which is a scraper. The angle between the rake and the water level is 8 ° -15 °. Vertical axis is driven by the motor on the truss. When the vertical axis rotating, the pulp along the feed chute on the truss entering to tank center, at the  same time flowing around the tank. Solid particles in the pulp gradually settle down to the tank's bottom, and scrapped by the scraper under the rake into the discharge bucket and released though the sand pump. The clarified water above flows from the circular overflow tank. If the thickener overloaded may cause the discharge bucket block or rake frame distortion. To prevent this phenomenon, it is equipped with signals safety device and rake lifting device.

Ⅳ、Installment and Usage:

1. Installment:

①Thickener installed on the site as a whole.

② Keep the spindle, rake concentric with the discharge basket.

③ Note: The thickener can not run reversedly.

2. Trial Run

① No-load trial: the run time should be 8 hours, the temperature of motor and transmission parts should not exceed 50 ℃.

②Load trial: testing time is 8 hours, filled with liquid water.

3. Running

①Check 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.

②Pay attention to the equipment's load, the overflow and concentrate's concentration.

③One 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.

④Fasten the bolts timely after the operation.

V. Lubricating method:

1. Reducer uses the HJ-40 (or J-50) oil and refill regularly.

2. Other lubricating points add grease every 24 hours.
