The RC-1 Quality Portable Gravel Rock Crusher is easy to use
The RC-1 Quality Portable Gravel Rock Crusher is easy to use. Consequently, material is gravity fed into the hopper and drops into the center of a high-speed rotating tube. As a result, centrifugal force throws the rock into a hardened steel impact wall. Speeds in excess of 400 miles per hour are generated. Because of this process, the harder the rock, the easier it shatters into instant powder. As a result of some particles being uncrushable, these particles will automatically pass through the unit without damage or hesitation. Consequently, all material after crushing passes automatically into a five-gallon bucket. The bucket forms a sealed chamber providing a low dust environment.
The RC-1 Cart added benefits
Because the RC-1 Crusher has a high center of mass on top of a 5 gallon bucket, it is prone to tipping over. As a result, the cart was developed for adding stability to the crusher. In addition, the bucket is easy to access for changing. Here is the link for the RC-1 Cart.
The RC-1 crushes all rock types
Ideal for crushing all types of quartz, schist, limestone, etc. This new machine is also ideal for crushing black sand concentrates to release any encapsulated micron gold for further processing. Additionally this machine will crush volcanic basalt and granite gravels into rock dust for garden soil enhancement.
Rock dust for your garden
Growing high quality crops requires more than just organic material. More than three key elements, nitrogen, phosphorous, and potassium are required. Because plants use up to 40 key elements, more elements should be made accessible. You can learn more from these articles: Rock Dust Primer, How To Use Fertilizers – Rock Dust, and Rock Dust and Remineralization. Buying rock dust can be expensive. At 1.25 pounds per square yard, at a price of $1.00 to $10.00 a pound, why not make it yourself. Granite river rock and volcanic basalt are easy rocks to find for crushing for garden use.
The RC-1 production rate
The RC-1 crusher is mounted to a vertical 5 horsepower engine. This machine is capable of producing up to 400 pounds of grind in just one hour. This results in a single pass, dependent on rock type, product that is 1/8″ and smaller. Therefore, multiple passes may be desired for finer grinds down to 120 to 180 mesh. Designed primarily as a pilot mill, this machine is not a production machine. However, it processes more than enough rock dust for home gardeners and enough material for testing the feasibility of larger crushers for gold processing or a rock dust business. The maximum rock size that this unit will handle is one inch. This is perfect for most home garden jobs, prospectors, and feasibility studies.
Works with your shop vacuum
The RC-1 Quality Portable Gravel Rock Crusher produces fine powder dust. The Crusher also comes with a 5 gallon bucket specially fitted with a 2-1/2″ shop vacuum hose port. As a result, you just attach your shop vacuum to the output port and you collect the vary fine dust. Therefore it is easy to maintain a dust free work environment. The larger particles stay inside the bucket. These are then easy to return to the crusher chute for additional processing. It’s easy.
