HVI sand making machine adopts advanced technology and the best design of the material impact angle of the crushing chamber. Its wearing parts are not easy to wear and consume. The advantages of the equipment are as follows:
The structure of the feed hopper is an inverted prism (or cylinder). The feed port is equipped with a wear-resistant ring. The incoming material from the feeding equipment enters the crusher through the feed hopper.
The role of the distributor is to separate the incoming material from the hopper, so that part of the material directly enters the impeller and is ejected out, and the other part of the material is impacted and crushed by the high-speed material ejected from the impeller to improve the crushing efficiency.
The crushing process of materials occurs in the vortex crushing chamber. The wall of the crushing chamber is separated by the material lining layer, so that the crushing is limited to the materials and plays the role of wear resistance and self-lining.
The material flows into the vortex crushing cavity from the upper part of the machine. The high-speed rotating impeller crushes the material scattered around the impeller in the form of an umbrella.
After the materials collide with each other, the material layer between the impeller and the casing will form a vortex flow for multiple collisions, friction and crushing, and then be discharged from the lower discharge hopper. The particle size of the finished product is controlled by the screening plant.
During the whole crushing process, the materials will be crushed by themselves through impacting each other, which reduces pollution and prolongs the mechanical wear time. The ingenious air circulation inside the vortex cavity eliminates dust pollution.
With the excellent combination of jaw crusher and cone crusher, the sand making process is so simple and highly automated that the whole set of production line only needs 1-2 people to complete the whole processing flow of river pebbles.
The sand making machine is the core equipment of the whole m sand production process. The efficiency of sand making is more than 40% higher than that of manual sand making, saving a lot of manpower, material and financial resources for the enterprise.
While effectively improving the sand making efficiency, the material is shaped. The processed river pebbles not only reach the standard of building sand in terms of hardness and strength, but also have good grain shape.
The overall energy and power consumption of this production line are about 30% lower than that of the ordinary river pebble sand production line. In addition, the ideal production state of zero dust and zero noise is fully realized in the sand making process.
Fote Heavy Machinery as a professional manufacturer of sand making machines has its production workshop and R&D organization. The sand making plant supplier Fote has the strength and ability to help users make reasonable plans according to the needs of users and actual production conditions.
The crushing method of "rock on rock" is suitable for materials above medium hard with high abrasion-resistance, such as basalt, quartz, granite, etc. Under the working condition of "rock on rock", the finished product has a better grain shape and more powder content.
The crushing method of "rock on iron" is suitable for materials below medium hard with low abrasiveness, such as limestone, dolomite, etc. Under the working condition of "rock on iron", the crushing efficiency is higher, the wear cost of protecting plates is higher, but the finished product grain type is slightly worse.

No matter how old you are, rock collecting can be a fun, interesting hobby. It doesn’t require any special knowledge — all you have to do is find a few rocks that catch your eye in your yard, and you’re ready to go — but you can learn quite a bit along the way about different types of rocks and how they’re formed
If you want to bring out the true beauty of the rocks you find, though, a rock tumbler is an essential tool for your hobby. With a tumbler, you can polish rocks to give them a smooth, almost glass-like finish. Polished stones can be set out for display in your collection, or you can even turn them into creative pieces of jewelry
But in order for your rocks to look as attractive as possible, you need a good rock tumbler to get the job done. To choose the right model, you need to know what type to look for, as well as what features are most important
Rock tumblers are small machines, usually small enough to rest on a tabletop. They consist of a motor, a barrel, and a chassis upon which the barrel rests. Many tumblers have only one barrel, but there are models that use two barrels at the same time
Rocks and water are loaded into the barrel, along with some type of abrasive grit material. The grit is similar to the material used to coat sandpaper, and is rated along the same grades as sandpaper, such as fine, medium, and coarse
Once the barrel is loaded, the machine rotates, so the rocks inside begin to tumble. As the rocks move, the abrasive grit constantly washes over the surfaces of the rocks. This erosive action simulates the same process that takes place when a rock washes down a stream or river
To get the proper texture and finish for your rocks, you tumble them in stages. In most cases, rocks are tumbled for one week with coarse grit, a second week with medium grit, and a final week with fine grit, or polish. Depending on the type of rock, you might also opt for a pre-polish stage. The rocks and tumbler must be cleaned carefully between each grit size
Rotary tumblers use a motor to rotate the barrel that holds the rocks, water, and abrasive grit. Similar to the way a clothes dryer moves your clothing, the rotary tumbler constantly lifts and drops its contents, causing the grit to wash over the rocks
Vibratory tumblers use a motor to vibrate the base beneath the barrel or bowl that holds the rocks, water, and abrasive grit. The action of a vibratory tumbler is somewhat reminiscent of a paint shaker at your local hardware store. Just like with a rotary tumbler, as the barrel vibrates, it creates friction between the rocks and grit to help smooth and polish them
However, vibratory tumblers are only effective in polishing and smoothing rocks. They don’t wear down angles the way that rotary models can, so they’re not effective for shaping the rocks. If you want your finished rocks to have more rounded edges, you should use a rotary tumbler
Some avid hobbyists use both. You can use the rotary tumbler for the coarse stages, which will smooth and round the edges of the rocks, then switch to the vibratory tumbler for the polishing stages. This shortens the overall time, and allows you to complete the entire polishing process using less grit
