Roll Crusher has achieved a breakthrough in aggregate production. Feldspar sand making machine ,also named as double roller crusher or roller sand making machine, runs by driving two motors and two pairs of rollers to grind the material fed. Double roller crusher can operate crushing material less than 80mm as well as the finished product size 50 mesh-20mm.
Due to the prohibition of natural sand mining, as well as the need for a large amount of sand and gravel for housing construction and highway construction, and the controllable particle size and full specifications of machine made sand, the machine made sand market has good sales and large profit margins.
1. Compared with hammer sand making machine, double roller sand making machine does not need to replace wearing parts.
2.The finished product features pretty shape, well gradation, low over-crushing rate and high output.
3. Feldspar sand making machine is superior to hammer crusher and impact crusher, and the average service life ofitsroller sleeve is more than 2 years.
4. Roller skin contains high content of chromium, manganese and other rare metal materials. Adjustable discharge size.
It is suitable for crushing sticky stone material into medium size. Roll crusher utilizes two rollers rotating in opposite direction to crush the material, which consists of motor, bracket, fixed rollers, movable rollers and springs. Most of its roller surfaces are glossy, and the bearings of the movable rollers can be moved along the machine frame and held against it by springs. Therefore, When a particularly hard object accidentally drops into the machine, the bearing can be moved out of the way to expel it. Furthermore, before the machine runs, the gap between the two rolls should be adjusted with shims to ensure the crushing size.
The feldspar sand making machine operates through rollers. The pebbles, put into the machine through the inlet, are crushed by the squeezing between the rollers. The discharge size can be controlled by adjusting the gap between the two rollers. If the gap becomes larger, the discharged size becomes larger. While the gap becomes smaller by compressing spring, the discharge size also becomes smaller.
Feldspar sand making machine is divided into several kinds: Spring fine crushing sand making machine, cardan shaft drive fine crushing sand making machine, hydraulic fine crushing sand making machine.
You can choose the machine according to your budget and the facts.
There are small, medium and large fine crushing sand making machine.

Customized Crushing Solution for Your Raw Materials
chat onlineThe double roll crusher uses two independently driven rollers that rotate in opposite directions, generating extrusion and shearing forces to crush materials. Feed material enters through the inlet, is crushed by the rollers, and discharged naturally. If unbreakable or oversized materials are encountered, the hydraulic cylinders or springs automatically retract the rollers to widen the gap, allowing the material to fall through safely. The discharge size is adjusted by controlling the hydraulic or spring pressure.
