Ballistic Screen, also known as ballistic screen, is a high-efficiency screening equipment specially used in urban solid waste sorting systems. It is widely used in the primary separation of materials such as domestic waste, packaging waste, and construction waste. The equipment mainly relies on a bouncing board with a certain angle to reciprocate and vibrate, so that materials with different physical properties can be automatically sorted according to their shape, density and bouncing performance.

The core structure of the Ballistic Screen includes multiple inclined bouncing boards that move back and forth. These slats vibrate at a specific angle and frequency, so that the materials move along different trajectories on the screen surface. Materials can usually be divided into three types: flat materials (such as paper, plastic film, etc.), which are pushed to the top outlet of the screen surface during vibration; rolling materials (such as plastic bottles, metal cans, spherical objects, etc.), which move to another outlet due to their rolling characteristics; fine materials (such as dust, glass fragments, etc.) fall into the lower collection area through the gaps between the slats.

Compared with traditional drum screens or vibrating screens, Ballistic Screen has significant advantages in processing dry, light, and diversified domestic waste. It has high sorting efficiency, low clogging rate, and can avoid problems such as plastic film entanglement. By adjusting the inclination angle of the slats and the movement frequency, it can flexibly adapt to different types of garbage and improve the intelligent sorting effect of the entire line.

The ballistic screen has a sturdy structure, easy maintenance, low operating energy consumption, and is suitable for 24-hour continuous operation. It is usually used as a pre-screening equipment in the intelligent sorting line, and is used in conjunction with wind separators, photoelectric separators, magnetic separators and other equipment to significantly improve material purity and recycling efficiency.

Ballistic Screen is an important equipment in modern solid waste resource treatment. With its reliability, adaptability and efficient sorting performance, it has become an important technical means to achieve garbage reduction, harmlessness and resource utilization. With the development of garbage classification and environmental protection industries, its application will become more and more extensive.

Ballistic Screen is an advanced equipment for solid waste sorting. It mainly relies on the inclined screen plate to do periodic bouncing motion to separate mixed garbage into three categories according to the material form, particle size and movement trajectory: light materials (such as plastic film, paper, etc.), heavy materials (such as glass, metal, stone) and medium-sized screen materials (such as organic matter, fine soil, etc.). This equipment is widely used in the resource processing process of urban domestic waste, packaging waste, construction waste and industrial solid waste, and is an indispensable core equipment in modern waste sorting lines.

Its working core lies in a set of inclined moving screen plates, which are installed at a fixed angle (usually 10°\~20°) and swing back and forth at a certain frequency. This swing combined with the angled design of the screen plate will cause the material to bounce and slide on the screen surface. Due to the differences in the movement characteristics of different materials under stress, their running trajectories and distribution behaviors on the screen surface will naturally differentiate, thereby achieving effective classification.

Lightweight materials are easily bounced and thrown to the far end of the equipment due to the large impact of air resistance and low density; heavy materials usually slide to the near end due to their high inertia and density; while fine materials fall into the collection area below through the gaps or holes on the screen plate and become screen undersize. This sorting method based on the dual effects of "physical motion laws" and "particle size morphology" does not rely on compressed air or complex sensors, and has the advantages of high reliability, low energy consumption and simple maintenance.

In order to enhance the sorting effect, Ballistic Screen is usually equipped with a multi-stage screen plate and a variable frequency control system, which can adjust the vibration frequency and screen plate angle to adapt to materials of different types and humidity. At the same time, in order to improve durability, the screen plate is often made of wear-resistant alloy or reinforced plastic material, which has good corrosion resistance and impact resistance.

Ballistic Screen uses the mechanical bouncing and tilted distribution structure design to use the bouncing behavior, particle size and density differences of the material for efficient physical sorting. It is an ideal equipment for rough sorting, pre-sorting and high-quality material recycling in the current automated garbage disposal system.

Ballistic Screen, also known as a bouncing sorter or projectile screen, is a highly efficient separation device specially used in solid waste sorting systems. It is mainly based on the differences in material form, weight and movement trajectory. It separates materials into three categories: "flat/soft objects", "rolling objects/hard objects" and "fine materials" through tilted vibration plates. It is an indispensable key equipment in the sorting lines of urban domestic waste, packaging waste, construction waste, etc.

The core feature of the ballistic screen is that it uses multiple tilted screen plates (vibrating rods or bouncing plates) that vibrate back and forth at a fixed frequency to continuously throw and transport the materials forward. During the movement, the material chooses different paths according to its own characteristics: flat materials (such as plastic film and paper) will slide along the top of the screen plate; rolling materials (such as plastic bottles and metal cans) will bounce upward; small-sized fragments will fall through the screen gap to achieve efficient three-way sorting.

One of its main advantages is its compact structure and low energy consumption. Compared with high-energy-consuming equipment such as air separation and optical separation, the ballistic screen relies on mechanical vibration to achieve sorting, and does not rely on compressed air or complex electronic systems. Therefore, it is more energy-saving and reliable, and suitable for long-term continuous operation. There is almost no material blockage during the operation of the equipment, and it has extremely strong processing continuity and system stability.

The ballistic screen is insensitive to the moisture content of the material and has strong adaptability. It is especially suitable for urban mixed garbage with more water and organic matter. Its high sorting accuracy can significantly improve the processing efficiency of subsequent automated identification equipment (such as optical sorters and manual sorting tables). According to different processing volume requirements, the equipment can be configured with different numbers of vibrating screen plates and screen gap spacing, which is highly flexible and suitable for large, medium and small garbage treatment plants.

In terms of maintenance, the Ballistic Screen has a simple design, few key components, low wear, replaceable vibrating screen plates, convenient daily maintenance, long service life, and low comprehensive operating costs. Through the closed or hooded design, it can also effectively reduce dust and meet environmental emission requirements.

Ballistic Screen has become an important equipment in modern solid waste resource treatment systems due to its advantages of high efficiency, low energy consumption, high sorting accuracy, strong adaptability and easy maintenance. It is particularly suitable for use in conjunction with air separation, magnetic separation, optical separation and other technologies to improve the overall sorting efficiency and resource recovery rate.
