With more than six decades of experience in engineering and manufacturing vibratory equipment, General Kinematics excels in creating energy-efficient, high-quality vibratory mining equipment to solve the industry’s most challenging screening problems. Our equipment has been refined for decades to provide maximum uptime and efficiency. After installing GK’s STM-SCREEN™, users reported increased:
Reliability – Experience the most reliable screen in the industry, with an average service life 5x that of a brute force model.
Efficiency – Improve your throughput by up to 30%.
Capacity – Increase your screening capacity by up to 40%.
The STM-SCREEN™ vibratory mining screens have a 4x retention rate for improved screening. As a part of the STM-SERIES® Heavy-duty Screens, the STM-SCREEN™ was built to last. Our patented modular design uses a center spline to significantly increase structural integrity and allow easy assembly and disassembly for quick transport and installation.

Experience the Two-Mass Advantage
General Kinematics engineered the STM-SCREEN™ Two-Mass Vibratory Screen to maximize the efficiency and capacity of screened minerals. In the past, brute force mining screens struggled to keep up with material surges, leading to blockages and downtime. That’s why General Kinematics built the STM-SCREEN™ using Two-Mass technology to combat the difficulties associated with brute-force vibratory mining screens. Now, you can screen more material than your old brute force screens– in the same footprint.
GK’s Two-Mass technology is load-responsive, allowing the STM-SCREEN™ to respond positively to material loading. Two-Mass equipment can maintain a consistent stroke during material surges, enabling the unit to screen minerals the same regardless of material load. The dual in-board vibratory motors eliminated the need for expensive belts, shafts, and bearings associated with brute force models.
