Linear motion screening machine, also known as linear motion screening machine, is a highly efficient vibration equipment commonly used for screening, grading, impurity removal and dehydration of powder and granular materials. It mainly relies on the linear vibration generated by the vibration motor or exciter to throw the material on the screen surface in a straight line and push it forward, thereby achieving multi-level separation and precise screening of the material. Linear motion screening machine is suitable for screening accuracy between 2 mesh and 500 mesh, and has the ability to flexibly configure 1 to 6 layers of screens. Different models of equipment can process materials ranging from 500 kg to 60 tons per hour, especially suitable for large batches.
Linear motion screening machine includes common linear vibration screens and high-efficiency banana screens, which can meet the needs of different material screening processes. The linear vibration screen has a simple structure and is suitable for fine grading of dry powders and particles. The processing capacity is usually 1 to 30 tons/hour. The number of screen meshes can be selected from 1 mesh to 500 meshes according to demand. It is widely used in chemical, metallurgical and other industries. The banana screen uses a multi-stage inclined screen surface structure, which makes the material distribution more uniform. It is suitable for high-humidity, high-viscosity or large-scale processing scenarios. The processing capacity can reach more than 60 tons/hour and is often used for wet screening of ore. Both support customized screen surface layer number and material configuration to ensure screening efficiency and production adaptability.
Linear motion screening machine has many technical advantages, making it an ideal choice in screening applications. Its high efficiency and low energy consumption are reflected in the optimized vibration parameters and reasonable screen surface angle design, which can achieve rapid stratification and accurate screening of materials while maintaining low power consumption and low noise operation. The equipment has a stable structure, and the main components are made of high-strength carbon steel or stainless steel. The screen frame is formed by laser cutting and high-precision welding to ensure long-term continuous operation without deformation. In terms of configuration, it supports multi-layer screen combination, open or closed structure selection, and can flexibly respond to different material characteristics and production environment requirements. At the same time, the equipment can be integrated with automatic loading and unloading systems.
The working principle of the linear motion screening machine is based on a linear vibration trajectory. The dual vibration motors in the screen box rotate synchronously in opposite directions to generate an exciting force, so that the material is thrown up and pushed forward on the screen. Under the combined action of vibration force and gravity, the material can be quickly screened and graded. The equipment structure is mainly composed of a screen box, a screen, an exciting device, a shock absorption system and a chassis, and the screening process is efficient and stable. According to process requirements, the screen can be set to 1-6 layers, and different apertures and materials (such as stainless steel mesh, polyurethane mesh, etc.) can be replaced to adapt to the screening of various granular or powder materials. In order to improve operating efficiency and cleanliness, the equipment can also be equipped with a sealing cover, a dustproof device and a quick-release structure, which is suitable for high-standard production environments.
In the selection process, the material particle size distribution, processing volume requirements, screening goals (grading, impurity removal or dehydration), material characteristics (such as viscosity, humidity, density) and on-site space and cleanliness requirements should be considered. Reasonable screen selection and vibration parameter setting will directly affect the screening efficiency and equipment life.
Linear motion screening machine is suitable for efficient screening of granular, powdered and partially water-containing materials, covering a wide range of industries such as ore, chemical, food, agriculture and building materials. Typical materials include quartz sand, iron ore powder, plastic granules, calcium carbonate, powdered sugar, grains, feed granules, cement and fine sand, etc., suitable for various process requirements such as coarse screening, fine screening and impurity removal. The equipment supports flexible configuration of screen mesh from 2 to 500 mesh to meet the requirements of different particle sizes and screening accuracy. Among them, the linear vibrating screen has a compact structure and stable operation, which is suitable for screening dry powder and small and medium-sized granular materials, and the processing capacity is generally 500 kg to 30 tons per hour. The banana screen is particularly suitable for wet, highly viscous and high-yield materials. Its multi-stage inclined screen surface design effectively prolongs the material residence time, and the screening capacity of a single device can exceed 60 tons/hour. Both devices have excellent performance in screening accuracy and efficiency, are suitable for medium and high-intensity continuous operation scenarios, have high stability and low failure rate, and are important equipment for material classification and processing in industrial production.
