A vibratory mill is a machine used for grinding materials. These machines are a critical component for mining and mineral industries, but not all machines are made equal. New technology is advancing the vibratory mill’s capabilities, improving outputs and production for several factories and mines.
Grinding can be done in batches, or in a continuous flow process (which is more common). First, material enters one end of a vibratory grinding mill drum into horizontal cylinders. Then, the mill uses a vibratory motion to mix and grind the particles, with operating speeds ranging from 800 to 1500 rpm. Typical vibratory mills use attrition and low energy impacts to grind materials properly.
The material migrates through grinding media as the drum vibrates. It then flows out through a perforated plate and is discharged for screening. If necessary, the material can be recirculated and added back to the drum to run through the cycle again.
Vibratory mills are one of several technologies available in the vibratory grinding market, and there are many benefits to this process.
On the other hand, vibratory drums do have some limitations.
The design of vibratory mills manufactured by General Kinematics has evolved to keep up with market trends and developing needs in the industry. Features like sub-resonant design and double barrel drums increase efficiency and decrease costs.
Thanks to a combination of a smaller drive force and better-distributed loads, our sub-resonant mill consumes less power and has improved structural reliability. This also allows for increased capacity with a larger drum design. Drums as large as 6’ x 18’ are currently available, but we’re continuously working to increase that size even more.
Our double barrel grinding drum also improves operating efficiency and production. Rather than increasing the machine size to increase capacity, the double barrel drum boosts grinding energy by doubling the available spring locations. Instead of using ballast weights on the inactive side of the barrels, a set of springs makes use of the space to increase the grinding rate and energy of the barrels. If this makes you nervous, all of our equipment can be monitored 24/7 by utilizing Vertex™ to ensure safety and minimize downtime!
Grinding operations are critical processes in many industries. As existing operations evolve along with an industry’s needs, manufacturers must work hard to improve vibratory grinding technology to keep up. The technologies on our existing vibratory mills can significantly increase safety and efficiency while decreasing downtime and total cost of ownership.
