High-Quality Smooth and Teeth Type Double Roller Crusher Companies, Pricelist

The double roller crusher is a stone crushing equipment used for coarse and fine breaking and it belongs to secondary crushing machinery. It is featured by double rollers which can be smooth roller or teeth roller type. Smooth roller crushers are commonly used for breaking stones and making sand with 1-3 fine discharging size. Teeth roller crushers are used for breaking coal with coarser output size compared with smooth ones. Henan Ascend machinery is a leading enterprise in manufacturing double roller crushers professionally for more than 10 years.

Product Description

Working Principle of Hammer Crusher

When the crushing machine begin to operate, the motor drives the rotor to spin at high speed, materials are fed into the crushing cavity evenly, and then be impacted, cut and tore by high speed spinning hammerhead till they are completely crushed. Meanwhile, the gravity action of materials forces them to crash the baffle and grate bars on the frame. Materials with particle size smaller than the screen size will pass the sieve plate while those with bigger particle size are stopped on the plate and will continue to be impacted and grounded by the hammer until they are crushed to the required particle size. Finally, crushed materials will be discharged from the hammer crusher through the sieve plate.

Advantages of Roller Crusher

1. More crushing and less grinding

It could reduce the particle size and improve the crushing characteristics of the materials to be crushed. The crushed products are mostly cubes in the shapes with less needle-like content without tension or cracks.

2. Low operation cost and long service life

The tooth roller of the roller crusher is made of high-yield wear-resistant materials, which has a strong impact on high wear resistance. It has the advantages of small loss and low failure rate when crushing materials, reducing the maintenance costs in the later stage.

3. Environmental concepts

The roller crusher is equipped with advanced environmental protection devices. The whole production process has low noise, low dust, and low pollution, which meets the requirements of national environmental protection.

Frequently Asked Questions

Q1: How does the hammer crusher work?
The motor drives the rotor to spin at high speed. As materials enter the crushing cavity, they are impacted, cut, and torn by the high-speed hammerhead. Fine materials pass through the sieve plate, while larger materials remain for further crushing until they meet the output size requirements.
Q2: What shape are the crushed materials from a roller crusher?
The crushed products from the roller crusher are mostly cubic in shape, featuring less needle-like content and no tension or cracks, which significantly improves the quality of the final output.
Q3: Why does the roller crusher have a long service life?
The tooth roller is manufactured from high-yield, wear-resistant materials that offer exceptional impact resistance and low wear rates. This durability leads to a low failure rate and substantially lower maintenance costs.
Q4: Is the roller crusher environment friendly?
Yes. The roller crusher integrates advanced environmental protection systems, ensuring the entire crushing process operates with low noise, minimal dust, and very low pollution to comply with environmental standards.
Q5: What are the standard models and output capacities for the roller crusher?
Key models include the 2PG-400×250 (5-10 t/h output), 2PG-610×400 (13-40 t/h output), 2PG-750×500 (20-55 t/h output), and 2PG-900×500 (60-125 t/h output).
Q6: What is the feeding size limitation for these roller crushers?
The maximum input feeding size is 25mm for the 2PG-400×250 model, and up to 40mm for the larger models (2PG-610×400, 2PG-750×500, and 2PG-900×500).
