Introduction to drum screenDrum screening machine, abbreviated as drum screen. It is a new type of screening equipment that classifies materials based on their particle size. The process layout is simple and mainly consists of inlet and outlet, motor, reducer, frame, drum device, etc. It can be used in industries such as chemical, coking, mining, power plants, building materials, metallurgy, etc. Commonly used in the grading and screening of medium and fine-grained materials to improve material quality. The exterior is sealed by a sealed isolation cover to prevent contamination of the environment. The water flushing drum screen is another type of water flushing drum screen successfully developed by Dingfeng Vibration Machinery Co., Ltd. in Xinxiang City through long-term work experience. It replaces the original method of the water pipe not rotating with the drum in the past. The new method of the water pipe rotating with the drum produces a high-pressure spray like effect on the water pipe, which more effectively plays a role in screening and cleaning Characteristics of drum screenUsing specially designed screen mesh, with high screening efficiency and long service life; The installation inclination angle is small, and the sieve holes are not easily blocked; Simple structure and easy maintenance; Smooth operation with low noise; Small space occupation, convenient for process layout. Structure and working principle of drum screenDuring operation, the electric motor is connected to the drum device through a coupling via a reducer, driving the drum device to rotate around its axis. After the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface flips and rolls, causing qualified materials to be discharged through the outer circular sieve of the drum, and unqualified materials to be discharged through the end of the drum. Due to the flipping and rolling of materials inside the drum, materials stuck in the sieve holes can be ejected, preventing blockage of the sieve holes. Scope of application of drum screen1. Used for grading large and small stones in the quarry And separate the soil and stone powder2. Separate from sand and gravel in the sand and gravel field3. The coal industry is used for the separation of lump coal and coal powder, as well as coal washing (a component of coal washing machinery)4. The chemical industry and mineral processing industry are used for the classification of large and small block materials and the separation of powdery substances Precautions for drum screen1. Before driving, the inclined drum screen must be turned on first, and then the feeding equipment must be turned on. Before parking, the feeding equipment must be turned off first, and then the inclined drum machine must be turned off;2. It is strictly prohibited to adjust the equipment during operation;3. Regularly inspect and handle the rotary drum screen, and check it every day for the first three days of machine operation.4. Regularly check the lubrication of the bearing seat and gearbox. Under normal circumstances, add lubricating grease every 2 months. Remember not to use too much, otherwise it may cause overheating of the bearings. And clean the bearings once a year.5. Equipment that has been out of use for a long time should be remotely monitored for motor insulation during restart to prevent it from burning out;Other models of drum screensTrommel  Dustproof compound fertilizer drum screen
