Calcined coke is an important raw material for steel smelting and aluminum electrolysis industries. It is produced by high-temperature calcination of petroleum coke. Its particle size directly affects the performance of downstream products. In the production process of calcined coke, particles and powders need to be effectively screened and graded into different specifications and particle sizes to meet the needs of different industries for particle size levels. In order to solve the problem that traditional screening equipment often encounters problems such as insufficient screening accuracy and dust overflow when facing calcined coke, which is a light material with a low specific gravity and easy to generate dust, which not only affects the production environment, but also increases the risk of environmental pollution. Therefore, a new type of efficient and fine screening equipment is developed and designed to meet market demand.
The square swing screen has the characteristics of high precision, large output, self-cleaning, good sealing and high screen utilization rate. It supports single and double five-layer screen combinations, and the design can reach up to 10 layers, meeting the needs of multi-level screening and grading. It is widely used in fine screening production sites. The square swing screen is based on the screening principle of artificial swing design. It simulates the "shaking and tapping" movement through three-dimensional trajectory movement (horizontal, vertical, inclined). While ensuring the screening accuracy, the material pass rate is increased to more than 98%. The self-cleaning function of the screen effectively solves the problem of easy blockage of the screen, and effectively reduces production energy consumption, thereby reducing production costs for enterprises.
The gyrotary screening equipment can efficiently screen various fine and ultra-fine powders and particulate materials by simulating artificial screening movements. It is mainly composed of screen frame, screen, motor, transmission device, support frame and other parts. The working principle mainly relies on the movement of the eccentric mechanism to form a uniform reciprocating cyclotron motion, which is transmitted to the screen machine through the drive box. The material in the screen frame is thrown up by the inertial force and slides along the surface of the screen to achieve relative movement between the materials. Fine particles fall into the lower screen through the screen, and larger particles remain in the current screen to continue to participate in screening, so that the material can be fully screened and graded on the screen surface. Production users can adjust the motor speed and the position of the eccentric wheel according to the characteristics of different materials and screening requirements, and change the amplitude and frequency of the screen frame to achieve the best screening effect. With its high energy efficiency, high precision, self-cleaning, environmental protection and energy saving, it has become an important equipment in the field of calcined coke screening equipment.
In industrial production, screening and grading is a crucial process. With the continuous advancement of industrial technology and the increasing requirements for environmental protection, the application of new screening equipment in the calcined coke industry will become more and more extensive. In the future, it will be upgraded in the direction of intelligence and customization, equipped with advanced technologies such as AI visual recognition system and multi-functional integrated design to achieve more efficient and accurate screening and grading. At the same time, the application of new materials will further enhance the durability and environmental performance of the equipment and meet the market demand for high-quality calcined coke.
