Product description

Spring Roller Sand Making Machine is suitable for crushing sticky stone material into medium size. Roller 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.

What is Spring Roller Sand Making Machine

The Spring Roller Sand Making Machine?is suitable for coarse and medium crushing of brittle blocky materials in industries such as cement, chemical industry, power, mining, metallurgy, building materials, refractory materials, and coal mines. It has a large feed particle size and adjustable discharge particle size, and can crush materials with compressive strength ≤160MPa.

The Spring Roller Sand Making Machine crushes the material by falling through the feed opening into the space between the two rollers for extrusion crushing, and the finished material falls naturally. When encountering hard or unbreakable materials, the rollers of the roller crusher can automatically retreat under the action of the hydraulic cylinder or spring, increasing the roller gap, allowing the hard or unbreakable materials to fall, thereby protecting the machine from damage. The two rollers rotating in opposite directions have a certain gap, and by changing the gap, the maximum discharge particle size of the product can be controlled. The double-roller crusher uses a pair of opposite rotating round rollers, while the four-roller crusher uses two pairs of opposite rotating round rollers for crushing operations.

Reasons for?choosing?us

1. Compared with hammer sand making machine, stone roller crusher does not need to replace wearing parts.

2. The finished product features pretty shape, well gradation, low over-crushing rate and high output.

3. Yellowish brown stone roller crusher 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.

River pebble roller crusher working principle

The? Roller Mill Crusher?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.

working principle

The 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.
