Product description

What is Flat Roller Crusher

The Flat Roller Crusher 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 Flat Roller Crusher 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.

It 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.

Sand Production Application

In sand production lines, the double-roll crusher functions as a sand-making machine, offering advantages such as no wear parts, low maintenance costs, adjustable sand particle size, high yield rate, and excellent sand particle shape. It is widely used in the sand-making industry.

Mineral Processing Crushing Applications

In the mineral processing industry, double-roll crushers or high-pressure roller mills are employed for fine crushing operations. Positioned upstream of ball mills, they can reduce 2-3 cm ore particles to less than 1 mm, significantly enhancing the operational efficiency of mineral processing ball mills and boosting overall production productivity.    

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.
