CLEVELAND VIBRATOR CO.
Frequently asked questions
Common questions about CLEVELAND VIBRATOR CO. from 3G Electric.
What is the difference between the Cleveland Vibrator Co. VM-25 and VM-38 piston vibrators?
Both are end-mount general purpose piston vibrators with a 1/4 in hose connection and 100 lb force output. The VM-25 operates at 13,500 vibrations per minute and 2 cfm at 80 psi, while the VM-38 operates at 10,600 vibrations per minute and 2.1 cfm at 80 psi. The higher frequency of the VM-25 suits finer materials or smaller bins where rapid, lower-amplitude vibration is effective. The VM-38's lower frequency may be preferred where a slightly slower action is acceptable. Selection depends on the material characteristics and the response of the bin or chute structure.
What air pressure and flow do Cleveland Vibrator Co. piston vibrators require?
Requirements vary by model. Examples from the 3G Electric catalog include the 2210125 at 6.3 cfm and 60 psi, the 2210050 at 3.8 cfm and 60 psi, the 2210100 at 5.0 cfm and 60 psi, and the VM-25 and VM-38 at approximately 2 cfm and 80 psi. Inlet sizes range from 1/8 in NPT to 1/4 in NPT. Plant air systems should be evaluated for both pressure and available flow at the point of use, since undersized supply lines can reduce force output and frequency below published ratings.
Are Cleveland Vibrator Co. sieve shakers available in different heights?
Yes. The mechanical sieve shakers listed by 3G Electric include analog vibration models with 12-inch and 15-inch overall heights, corresponding to part numbers VJ1212-110V and VJ1515-110V. The height generally relates to the number and diameter of sieve trays the unit can hold. Both models use vibration as the sieving action and are intended for particle size analysis and material separation of powders, aggregates, and granular materials. Selection depends on the sieve stack configuration and the sample volume required by the test method.
What is the difference between a Cleveland Vibrator Co. piston vibrator and a ball or roller vibrator?
Piston vibrators use a reciprocating piston driven by compressed air to produce a linear force, typically at frequencies from about 7,600 to 16,000 vibrations per minute and force outputs from 100 lb to 600 lb in the models listed by 3G Electric. Ball and roller vibrators use a rotating mass to generate vibration and are generally used where a rotary or orbital vibration pattern is acceptable. Piston units are often chosen for direct mounting on bins, chutes, and hoppers where a defined linear force and frequency are needed. The correct type depends on the material, the structure, and the desired flow behavior.
Can Cleveland Vibrator Co. piston vibrators be used in corrosive or washdown environments?
Some models are available in stainless steel. The VM-25 SS is an end-mount piston vibrator with the same performance as the standard VM-25: 13,500 vibrations per minute, 100 lb force, 2 cfm at 80 psi, and a 1/4 in hose connection. Stainless-steel construction is relevant where moisture, washdown, or mildly corrosive atmospheres are present. For aggressive chemicals or hazardous locations, buyers should confirm material compatibility and any required enclosure or certification with the manufacturer's published data before specifying.
How do I select a Cleveland Vibrator Co. piston vibrator for a hopper or bin?
Start with the material characteristics, bin geometry, and the discharge problem. Note the available air pressure and flow at the mounting point. Then compare models by force output, frequency, air consumption, inlet size, and mounting type. For example, a 600 lb force unit such as the 2210125 at 7,600 vibrations per minute may suit a larger bin or denser material, while a 100 lb unit such as the VM-25 at 13,500 vibrations per minute may be appropriate for smaller vessels or finer powders. Mounting location and structural stiffness also affect performance, so field adjustment of pressure or mounting position is common.
