Double tooth roller crusher

Double-toothed Roller crusher, also known as 2PGC crusher, belongs to the type of double-roller. The shape of the roller surface can be divided into coarse and fine-toothed rollers. It can be adjusted according to the size of the material and is suitable for brittle and soft materials. The double-tooth roller crusher is suitable for sintering, coal, cement, silicate, glass, ceramics, and other industries. It is suitable for the crushing of brittle materials below medium hardness. It is mainly used for medium and fine ore crushing operations.

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

Cement, chemical industry, electric power, mining, metallurgy, building materials, refractory materials, coal mines.

Working Principle

The two rollers have wedge or gasket adjusting device, wedge device with the top adjustment bolt, when the adjustment bolt wedge block upward pull up,the wedge pushes the movable roller away from the fixed roller, two roller gap becomes larger, the discharge size becomes larger, when the wedge block down, activity roller compression spring (or pressing oil cylinder) under the action of two gap becomes smaller, the discharge size becomes smaller. Gasket device is through increase or decrease the number of gasket thickness to adjust the size of the discharge size, when adding gasket will make two roller wheel gap bigger, when reduce gasket will make two roller wheel clearance decrescent, the discharge size 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.
