FLG classifier instructions

I. Use and scope of the machine The spiral classifier is a beneficiation machine that performs mechanical classification by means of different solid particle sizes, different shapes, different specific gravities, and thus different sedimentation speeds in the liquid. This machine is mainly used in the wet grinding closed circuit cycle, and is combined with the ball mill to form a circulation process to classify the sand mine. Or used for washing, deliming and other operations. Second, the appearance of the machine Figure 1 Single spiral classifier (sorghum type) 1.

Fourth, the structure and working principle of the machine 1. Structure: This machine is composed of the following main parts: (Refer to Figure 1) 1. Transmission device 2, spiral 3, trough body 4, elevator 5, lower moving seat (bearing) 6. Main structure description of the discharge valve: The transmission device FLG-500.750 is driven by a motor, a reducer and a coupling. FLGâ€”1200 (2FLG) 1200, 1500 and FLG (2FLG)â€”1200, 1500 Drive the screw shaft with electric motor, reducer and bevel gear. The FLG (2FLG)-2000 is driven by a pair of spur gears and a pair of bevel gears (or two pairs). Spiral: consists of a hollow shaft and a spiral lobe, a moving frame, and the hollow shaft is a seamless steel pipe (A3 or 20#). Spiral blade: A3 white cast iron or steel article is to be replaced as wearing parts wear. Tank: welded by A3 steel plate, no cracking after welding, no leakage. Lifting structure: divided into two types (1) hand worm gear reducer, lifting the spiral through the wire rope. (2) Motor, reducer, through the bevel gear screw drop screw. Lower moving seat: support FLG-500. FLG-750, FLG-1000, FLG-1200, 2FLG-1200, FLG-1200, 2FLG-1200, FLG-1500, 2FLG-1500, FLG-2000, 2FLG-2000 classifier The spiral rotates in a fixed position. Lower bearing diagram

1. Single row radial ball bearing 2, bearing body 3, flange 4, fixing sleeve 5, sealing ring 6, gland 7, sealing ring 8, lubricating oil tube working principle: The inclination angle of FLG500.750.1000 classifier and horizontal plane is 14 Â°25â€², FLGâ€”2000, 2FLG2000 and the horizontal plane inclination angle is 18Â°, FLG1200, 2FLG1200, FLG1500, 2FLG1500, FLG1200, 2FLG1200 and the horizontal plane inclination angle is 12Â°-16Â° After the motor is started, the speed reducer coupling (or gear) is adopted. The bevel gear drives the spiral blade to rotate. In the ball mill, the slurry enters the water tank from the front side of the water tank into the water tank. A sedimentation tank is formed in the front part of the tank. At some time, the spiral body rotates continuously, the slurry is affected by the stirring, small particles float on the surface, and the human overflows. The water tank, while the large particles sink into the bottom of the groove, the spiral blades are pushed toward the tail of the tank and discharged into the ball mill (or other device) for re-grinding. V. Installation, operation and maintenance of the machine 1. The installation machine is inspected without damage, and the screws are not loose and can be installed. The classifier should be firmly installed on the concrete foundation that has been poured. The foundation design should have a good supporting effect to minimize the shearing force on the screw. 2. After the operation and the working principle of the spiral classifier are clear, the machine can be operated. (2) When the spiral body is in working condition, if it needs to stop immediately after special fault (such as stuck, overload), immediately lift the spiral body out of the slurry surface, and never allow the spiral body to press in the slurry, and quickly open the discharge valve. Avoid fouling. (3) When starting again, the spiral should be lowered to a certain position to turn the spiral. (4) If the machine needs to stop when using the product, the feeding should be stopped first, and the operation can be stopped after the material is classified. 3, maintenance (1) Where and lubrication points are lubricated with sodium-based grease (GB492-65) or calcium-based grease (GB491-65). (2) Each shift should check whether the lubricating oil inside the reducer is on the oil needle line and change the oil every 6 months. (3) Always check the lower support or intermediate tile, the bearing, the seal is damaged, and the bearing is damaged, so that it can be replaced in time. (4) The bearing lubrication of the lower bearing must be injected into the bearing with a manual dry oil gun every 4 hours to maintain the sealing performance of the bearing. Manual dry oil guns and plastic tubes are provided by the user. 6. After the test machine is assembled and 2-4 hours of no-load test, the following conditions shall be met: 1. The rotating parts and parts shall be operated flexibly, and there shall be no collision, abrasion or research. 2. The temperature rise of the bearing is not more than 35 Â°C, and the maximum temperature is not more than 65 Â°C. 3. The lifting mechanism is flexible in operation, the journal can swing freely in the bearing, and the stroke switch should be sensitive and reliable. 4. The discharge valve is flexible and reliable. 5. The total speed ratio of the transmission should meet the requirements of the screw speed. 6. After the test is finished, check whether the screws of each part are loose or deformed. After the machine is tested, the unmachined surface should be painted with gray paint, uniform paint, no wrinkles, bubbles, curls, flow marks and crack defects. The exposed surface shall be coated with rust preventive oil and covered with oil paper. The following matters must be noted when packaging and shipping: (1) Packaging specifications and standards are implemented according to factory standards. (2) Strictly prevent the surface paint from being scratched and hit the body. (3) Wrap the technical documents in plastic film and put them in the box and seal them. (4) The machine must be lifted as specified to prevent deformation of the machine. (1) After the spiral is turned, it can start to feed the slurry and gradually increase the amount of minerals.
