The main body of the slime dryer drum is the main operating part of the whole system. The selection of materials, the design of the process and the quality requirements must be scientific and reasonable. Today, the main body of the drum is the main moving part of the whole system. The design and quality requirements of the process must be scientific and reasonable. Today, Xiangtong Machinery and everyone talk about the basic requirements of the drum body during production.
1) The cylinder material should not be lower than the mechanical properties of Q235-B in GB/T 700; in the cold storage area (the lowest temperature is lower than -20 °C), the cold bending test should be added. The surface quality of the steel plate shall comply with the provisions of GB/T 3274. For steel plates with a thickness greater than or equal to 40 mm, ultrasonic inspection shall be carried out on the area where the edge width of the finished material is 60 mm before cutting, and there shall be no defects such as cracks and delamination.
2) When making the ring section of the cylinder section, the number of longitudinal welds along the entire circumference, the section of the diameter of 3m or more shall not exceed three, and the length of the shortest imposition arc shall be greater than one-fifth of the circumference. No more than two sections of 3m and 3m in diameter, and the shortest imposition arc length shall not be less than a quarter of a circumference. The shortest length of the segment shall not be less than 1 m, and no such section shall be more than one section in a span and shall be placed in the middle of the cross. The longitudinal welds of adjacent segments shall be staggered from each other and the staggered distance shall not be less than 800 mm.
Application scope of slime dryer: High-efficiency and energy-saving slime dryer is a new type of drying equipment developed on the basis of drum dryer. It can be widely used in: 1. Coal industry, coal slime, raw coal, flotation clean coal, Drying of mixed coal and other materials; 2. Drying of blast furnace slag, clay, limestone, sand, quartz stone, etc. in the construction industry; 3. Drying of various metal concentrates, waste slag, tailings and other materials in the mineral processing industry; 4. Chemical industry Drying of non-heat sensitive materials in the industry.
In recent years, under the fierce attack of financial crisis, many relatively small-scale slime dryer manufacturers are on the verge of closure, and some large and medium-sized dryer manufacturers have also suffered large losses. The dryer industry is facing severe conditions. Hone and self-regulation. How to effectively break away from this kind of adversity has also become a topic of careful consideration in the growth of dryer manufacturers. At the same time as the system reform of the dryer manufacturers, in addition to correcting the bias of the enterprise, we must also focus on the reform of the equipment and the innovation of the beneficiation process, so that the enterprise will advance and grow in the current situation.
