Strong double toothed roller crusher

Introduction to Strong Double toothed Roller Crusher

The strong double toothed roller crusher, also known as the strong double toothed roller crusher, is a new concept of graded crushing equipment. It is completely different from traditional toothed roller crushers that rely on impact and compression to crush materials, but uses the combined action of shear and tension to achieve material crushing. Due to the use of low speed and special tooth profile, there is less over crushing and over particle of the material. The 2PLF and FP series strong grading crushers are mainly suitable for coarse and intermediate crushing of brittle block materials in industries such as coal mining, power, mining, metallurgy, and chemical engineering.

Working principle of strong double toothed roller crusher

The graded toothed roller crusher is driven by two electric motors to reduce the power through a reducer and drive two parallel toothed rollers to rotate towards each other. When the material falls between the two rollers of the graded crusher, the material is first screened by a spiral toothed or knife shaped toothed plate. Particles smaller than the discharge size directly pass through without being crushed and enter the discharge chute. Under the joint action of vertical stress or shear force, large pieces of material are split and sheared by the toothed roller teeth, stretched and crushed, and discharged from the discharge port.

Environmental conditions for the use of a powerful double toothed roller crusher

Only some of the toothed sleeve type strong grading crushers have a feed particle size of ≤ 600mm, allowing for small quantities up to 800-1000mm, and discharge particle sizes up to 150mm, 200mm, 300mm, etc; The feeding particle size of the toothed plate strong grading crusher is ≤ 300mm, allowing a small amount to 500mm. The discharge particle size can be 30mm, 50mm, 80mm, 100mm, etc., and it can crush coal and medium strength rocks. If the system only takes effective measures to remove iron and wood, the raw coal can be directly crushed without pre screening and manual selection, which can simplify the coal crushing process, reduce the height of the plant, and reduce the construction investment and production costs of coal preparation plants and power plants. The 2PLF series powerful crusher has obtained the right to use the coal safety mark and can be used for underground crushers.

StrongAdvantages of double toothed roller crusher

1. The grading crusher relies on shearing and stretching to crush materials, resulting in uniform particle size of the crushed products and low over particle and over powder situations.
2. The transmission device has a compact structure, flexible operation, low noise, and high safety.
3. Adopting dual overload protection of hydraulic coupling and "utility model" safety coupling, it is safe and reliable.
4. Adopting the "utility model" crusher toothed disc, the toothed disc is arranged in a spiral pattern, with good wear resistance and long service life.
5. The body adopts a modular design, and the combination between each unit is convenient and fast, making it easy to disassemble and transport underground and coal buildings.
6. The whole machine has a low height and is suitable for working environments with limited space.
7. According to user requirements, speed sensors and PLC programming can be installed to control the working status of monitoring equipment and achieve remote control.
8. Adopting an automatic oil supply system to extend the service life of bearings and reduce the workload of daily maintenance.
