Rock on Rock Crusher Model VSI-800
The VSI-800 is the lighter version of the VSI-900 rock on rock crusher, with the same design, dual-motor drive and Rockwell Crusher rotor. With a feed capacity of about 130 t/h, it produces 60–70 t/h of washed sand and suits medium-capacity sand and gravel plants. For a full introduction to this machine, read What Is a Rock on Rock Crusher?
Application
Producing manufactured sand with cubical grading for ready-mix concrete and asphalt, and reshaping aggregate. In the plant it sits after the cone crusher (hydrocone) and before the screen and sand washer.
Built by Rockwell Crusher
The VSI-800 body, chamber, rock shelf ring and frame are built in the Rockwell Crusher workshop, and we design, build and balance its rotor ourselves.

Comparison
VSI-800 or VSI-900: which should you choose?
The choice mainly depends on your plant capacity. If your feed is around 130 t/h, the VSI-800 does the job with lower power consumption. For high-capacity plants, the VSI-900 is the better choice.
| Specification | VSI-800 | VSI-900 |
|---|---|---|
| Feed capacity | 130 t/h | 400 t/h |
| Washed sand output | 60–70 t/h | 130 t/h |
| Motor power | 2 × 90 kW | 2 × 200 kW |
| Weight | 14,500 kg | 18,500 kg |
| Best for | Medium-capacity plants | High-capacity plants |
Features
Features of the VSI-800 rock on rock crusher
Lower power consumption
Two 90 kW motors are enough for medium plants and keep the power cost per ton of sand low.
Stone-on-stone crushing
Stone hits a rock shelf, not metal, so wear is low and the grains come out cubical.
Rockwell Crusher rotor
The rotor is built and balanced in our own workshop, and its rotor and spare parts are always available.
Lower weight and size
At 14.5 tonnes, it is easier to transport and install than larger models.
Custom builds
We can increase or decrease the machine’s capacity and specifications to match your stone and plant needs.
Production line
Where the VSI-800 sits in a sand and gravel plant
In a typical plant, quarry rock passes a grizzly feeder, is crushed in a jaw crusher and then in a hydrocone. Fine aggregate (up to 45 mm) enters the VSI-800 and becomes cubical sand. The product is then graded on a vibrating screen and washed in a sand washer.
FAQ
VSI-800 frequently asked questions
What is the capacity of the VSI-800 rock on rock crusher?
The VSI-800 takes about 130 t/h of feed and produces about 60–70 t/h of washed sand. Actual capacity depends on stone type, moisture and machine settings.
What is the motor power of the VSI-800?
It has a dual-motor drive with two 90 kW electric motors (2 × 90 kW).
What is the difference between the VSI-800 and the VSI-900?
The VSI-800 is the lighter model with 130 t/h feed capacity and 2 × 90 kW motors; the VSI-900 has 400 t/h feed capacity and 2 × 200 kW motors and suits high-capacity plants.
Can the VSI-800 capacity be changed?
Yes. Rockwell Crusher also builds the machine with higher or lower capacity based on the customer’s stone type and required output.
