Product Introduction
The document introduces a ballistic screen mechanism that utilizes an imported German crankshaft transmission. This system is designed to sort materials into three categories by bouncing off materials attached to packages, achieving an effective sorting process.

Working Principle
The mechanism operates using active and passive crankshafts, causing the screen unit to move in an oval pattern while neighboring paddles move asynchronously. When materials are dropped onto the central area of the screen unit, three-dimensional materials bounce off, two-dimensional materials climb over, and smaller materials are screened through holes, effectively separating materials into three types.

Technical Data
The document provides specifications for various models, including useful width, paddle length, power drive, throughput capacity, screening area, paddle quantity, RPM, sieve mesh, and voltage. Optional devices include an air fan support, motor hydraulic angle adjuster, top cover, and central greasing system.

Features
- Speed control via frequency converter for optimized performance.
- Self-cleaning between screen plates to enhance efficiency.
- Wind-assisted sorting for improved screening.
- Centralized lubrication system for ease of operation and maintenance.
- Quick-opening maintenance door for safety and convenience.
- Anti-wrap device on screen plate to protect the crankshaft.
- High wear resistance with Swedish Hardox steel screen and side plates.
- Hydraulic device for quick screen angle adjustment.
- Integral German crankshaft with a lifespan of at least 20,000 hours.
