Double smooth roller crusher

Roll Crusher Introduction

The double smooth roller crusher can be used for finely crushing various high and medium hardness ores and rocks in the industrial sectors such as mineral processing, chemical industry, cement, refractory materials, abrasives, building materials, etc., especially for the production of production of melon and mung rice-sand in the building materials industry have better effects than general crushing machinery.

The roller crusher is suitable for medium and fine crushing of solid materials, such as coal, coal gangue, coke, limestone, iron ore, quartz stone and sulfur ore in cement, chemical industry, electric power, mining, metallurgy, building materials, refractory materials, coal mines.

Roller crusher is mainly divided into double roller crusher and four roller crusher.

The roller crusher is equipped with two crushing rollers. According to the particle size required by the user, roll crusher can be divided into smooth roller crusher and tooth roller crusher. Smooth roller crusher is suitable for fine crushing operations where the feed particle size is less than 80mm and the final size 1-10mm. The gear roller type is suitable for the medium and fine crushing with feed particle size is less than 150mm and the finished product particle size is 5-30mm.

The four-roll crusher is suitable for the medium and fine crushing operation with the feed particle size less than 90mm and the finished product particle size 0.3-10mm.

Raw Materials

Coal, coal gangue, coke, limestone, iron ore, quartz stone and sulfur ore, etc.

Application

Mineral processing, chemical industry, cement, refractory materials, abrasives, building materials, etc.

Working Principle

When working, the crushed material will fall between the two rollers through the feeding port for squeezing and crushing, and the finished product will be discharged from the lower end of the discharging port. There is a wedge or gasket adjusting device between the two rollers of the roller crusher. There is an adjusting bolt at the top of the wedge device. When the adjusting bolt block is pulled up, the wedge will push the movable roller away from the fixed wheel, which is the two rollers. The gap becomes larger. When the wedge is downward, the gap between the two wheels of the movable roller becomes smaller under the action of the compression spring, and the discharge particle size becomes smaller. The shim device adjusts the discharge particle size by increasing or decreasing the quantity or thickness. When the shim is added, the gap between the two rollers becomes larger, and when the shim is reduced, the gap becomes smaller.

Features & Advantages

1. High Crushing Rate, high crushing efficiency, low over-crushing rate;

2. Wear Resistant Parts: the double roll crusher roller is equipped with a replacement wear resistant lining board with wear resistant material, with long service time;

3. The output particle size can be adjusted less than 150mm, automatically adjusted by adjusting the clearance of the roller, to meet the different crushing requirements of customers;

4. The roller crusher has a simple and reliable structure, and when it encounters large and hard clinker blocks, it can be handled manually under the condition of continuous operation.

5. Strong carrying capacity;

6. Convenient adjustment of the discharge size;

7. Small investment cost;

8. Low noise and less dust;
