Double-geared roller crusher

Brief introduction

The double toothed roller crusher is a new type of toothed roller crusher, which has a relatively large crushing ratio among similar crushing equipment. The crushing ratio can reach (5-8), and the roller surface shape can be divided into coarse and fine toothed rollers. It can be adjusted according to the size of the material needed for production, and can be matched with coarse toothed rollers or medium toothed rollers according to the characteristics and requirements of the crushed material.

Suitable for coarse and medium crushing of brittle and soft ores, this equipment has the characteristics of long service life of crushing teeth, uniform particle size of crushing materials, low over crushing rate, convenient maintenance, sensitive overload protection, stability and reliability. Suitable for brittle and soft materials, the double toothed roller crusher is suitable for industries such as sintered ore, coal, cement, silicate, glass, ceramics, etc.

Operational principle

The double toothed roller crusher uses the high extrusion force generated by the relative rotation of two wear-resistant toothed rollers to crush materials. After the material enters the gap between the two toothed rollers (V-shaped crushing chamber), it is subjected to the extrusion and shear forces caused by the relative rotation of the two toothed rollers. Under the squeezing, shearing, and grinding, the material is crushed into the required particle size and then discharged through the discharge port.

There is a wedge or gasket adjustment device installed between the two rollers, and the top of the wedge device is equipped with an adjustment bolt. When the adjustment bolt pulls the wedge upwards, the wedge will push the movable roller away from the fixed wheel, that is, the gap between the two rollers will increase, and the discharge particle size will increase. When the wedge is downward, the gap between the movable rollers will decrease under the action of the compression spring, and the discharge particle size will decrease. The gasket device adjusts the discharge particle size by increasing or decreasing the number or thickness of gaskets. When adding gaskets, the gap between the two rollers increases, and when reducing gaskets, the gap between the two rollers decreases, resulting in a smaller discharge particle size.

Performance characteristics

1. The unique cavity structure of the double toothed roller allows for strong feeding force, making it particularly suitable for coarse crushing.

2. The overload protection device of the double toothed roller crusher is sensitive, stable and reliable.

3. High productivity, uniform particle size of crushed materials, adjustable particle size after crushing, low over crushing rate.

4. The diversified tooth structure optimization design and assembly methods make the double tooth roller crusher more suitable for a wider range of applications.

5. The cross tooth layout allows the double tooth roller crusher to achieve mutual sorting effect when crushing materials, which is quite beneficial for crushing viscous materials.

Maoxin takes Macedonia friends to see China! The ancient Chinese civilization made significant contributions to fields such as art, literature, philosophy, science, technology, medicine, and architecture. There are many historical and cultural heritages in China. I believe these cultural stories with a long history are attractive enough to make Macedonia friends interested in Chinese Double-geared roller crusher products. If you have an interest in Chinese culture, let's take a look at it first. The Mausoleum of the First Qin Emperor, also known as the Qin Shi Huang Mausoleum, is a historic site located in Lintong District, Xi’an, China. It is the final resting place of Qin Shi Huang, who was the first emperor of China and the founder of the Qin Dynasty. The mausoleum complex covers an area of over 56 square kilometers and is surrounded by several smaller tombs, pits, and burial sites. The main tomb is located at the center of the complex and is comprised of a pyramid-like structure that rises over 50 meters high. The tomb was constructed during Qin Shi Huang's reign and took nearly 40 years to complete. The tomb is surrounded by a moat and an outer wall that is over 1.5 kilometers long, with four gates that guard the entrance to the tomb. The tomb is also guarded by an army of life-sized terracotta soldiers, horses, and chariots that are positioned facing eastward, ready to protect the emperor in the afterlife.
