It is extremely important to have your feeder vibratory motors set at the proper feed rate! You want to get the most production rate possible with your crusher, not to mention it’s crucial to your crushers generator running smoothly and automatically maintaining optimal health.

We want to let everyone know of the importance of keeping your crusher working at peak production capacity by maintaining a strong feed rate to the jaw. When the jaw is not kept full during operation the machinery does not pull enough on the generator for it to automatically regenerate the DPF Exhaust Filter (Diesel Particulate Filter) which can result in a very costly manual regeneration service of several thousand dollars. Continually running with a clogged DPF clogged can actually cause enough backpressure to cause serious damage to your generator engine.  There is an automatic shutdown feature to keep this from happening when your DFP Filter gets full, see our post about this here:

The first step to proper feeding is to be sure your crusher is as close to level as possible. The feeder is on a slight downward angle, you don’t want your feeder having to try to “feed uphill”. In this process, it’s key to know that you always want the vast majority of your crushers weight always riding on the chassis and wheels. The footpads and legs are only meant to stabilize the machine, simply extend them until the foot snugs up and stops bouncing. Do not try to use the legs to make excessive corrections in the leveling of the machine, but rather move the machine to a more level area. It’s ok to have the machine positioned very slightly “downhill” with the feeder getting a little help, but too far off level and your crusher can start “walking” requiring repositioning.

It’s also important to start the vibratory motors at the same time to keep them “in sync” and feeding equally from each side. They will make a louder noise when starting but should quiet down significantly after start up. If they don’t, simply shut them down, given them a minute to completely stop rotating, and start again pushing both start buttons at the same time to have them running in sync for balanced feeding.

It’s a simple adjustment to simply turn up the vibration level on the vibratory motors. The more opposing the weights are, the more counterbalanced they are and thus provide less vibration. The closer they are together to one side the more “off balance” they will be which provides more vibration. It’s not an exact science and almost always the factory feeder settings will be fine. As each site and material is unique, you may have to adjust the settings. Excessive dirt with moisture in your material can drastically slow down the feed rate as well, try to remove as much of that as you can before crushing. Skeleton buckets are a great solution, simply give each bucket a good shake before dropping into the hopper.

Here’s the feeder vibratory motor adjustment video:

Here’s a picture of the overlap showing approximately where the weights should be set for most recent models with the 1″ steel feeder wear plates.

MODELS WITHOUT THE WEAR PLATES REQUIRE A DRASTICALLY LOWER VIBRATION SETTING-CALL FOR INFO!

It’s always best to keep your jaw full when crushing for maximum productivity as well as trouble free generator and crusher operation! 

Here’s a picture of a Senya 3 jaw being “well fed”:

Check out this YouTube link to a video for an example to be sure your crusher is getting fed enough, LET THE BIG BOY EAT!:

The design of the crusher virtually eliminates the possibility of “overfeeding”, the feeder will self-regulate itself keeping the jaw full to the top almost all of the time with proper feeder vibratory motor settings. The tradeoff of too slow feed rate is greatly reduced productivity of your crusher and the possibility of the generator not working hard enough to automatically regenerate is DPF Exhaust Filter. Alternatively, a well-fed jaw gives you max production, generator health, and you may have to jump up and “pull a corner” of a rock to free the inevitable binding up of material from time to time.                                                        

It’s also important to not run the generator for any significant period of time while not crushing for the same reasons mentioned above regarding the DPF Filter/Exhaust Catalyst regeneration process.
