As the efficiency leader of the low-carbon pioneer family, the Powertrack mobile impact crushing unit, with its outstanding efficiency and high production capacity, has won the admiration of many. Thanks to its high crushing ratio, the PT Pro I-13DS impact crushing unit often operates independently and can produce high-quality finished aggregate with smooth particle shapes.

The core component of the Powertrack impact crushing unit - the SRHeavy® impact crushing main unit - has made significant contributions. The SRHeavy® impact crushing unit has a high crushing ratio, large throughput, a simpler and more efficient crushing process, and produces high-quality product particle shapes. Its application scope is wide, playing an important role in industries such as construction, building materials, ore crushing, railways, highways, energy, transportation, cement, mining, and chemicals, and can be regarded as a "low-carbon pioneer superman".

Highlights of the crushing unit

01 large feed size and high output

The SRHeavy®SF series impact crushing unit has been optimally designed and adopts a single-chamber crushing structure, with a larger crushing chamber and a larger feed particle size.Taking the SF1213 impact crushing unit as an example, the feed opening size is 1 330x800 millimeters, and the maximum feed size can reach 600 millimeters.At the same time, by optimizing the breaker plate liner and high inertia rotor design, the production efficiency under various application conditions has been significantly improved.

The rotor design has been continuously improved, with an increase in rotational inertia and an enhancement in equipment output. The maximum production capacity of the SF1213 impact crusher main unit can reach 400 tons per hour. It also has a larger crushing ratio, with the maximum ratio reaching 20:1. By using a single-stage impact crushing method, standard products can be easily produced, which not only reduces investment costs but also saves energy.

02 Technical upgrade and reliable quality

The Metso Group enjoys a high reputation in the market for the efficiency and reliability of its equipment, as well as the quality of the final products. The SRHeavy®SF series impact crusher mainframe inherits this excellent quality.After years of research and technological upgrades, SRHeavy has achieved significant improvements in the durability of vulnerable components (such as hammer, screening liners, side frames of the machine frame, etc.) and the reliability of mechanical components of the crusher (such as drive shafts, bearings, etc.).By optimizing the equipment structure, this series of crushing units can produce more round-shaped particles and more fine-grained products.

03 The unique plate hammer locking device is more durable

The SF series impact crushing unit is not only equipped with various strength and complete types of wear-resistant liners, but also innovatively developed a unique hammer locking device. The hammers of this crusher are firmly fixed on the rotor through a set of wedge block assemblies, and the tightening torque is greater compared to other manufacturers. In addition, the contact surface between the hammers and the rotor has undergone mechanical precision processing, eliminating the gap between them, which significantly reduces the risk of hammer fracture. This unique design breaks through traditional limitations and makes it possible to use cast iron as the hammer material, further improving the durability and economy of the hammer.

04 Easy to maintain and with adequate security measures in place

• The same hydraulic device of the SF series impact crusher can be used to open the frame and also as a regulating device for the discharge port.

• Through the safety doors on both sides of the frame, it is convenient to enter the interior of the crusher for inspection, maintenance and component replacement.

• The hammer can be replaced vertically or horizontally, enabling the equipment to be applicable to various different application conditions.

• The limit protection device and sensors on the frame can prevent the equipment from accidentally starting during maintenance and upkeep, providing a reliable guarantee for the safety of maintenance work.

05 Flexible application and easy operation

Equipped with a hydraulic adjustment device, it enables more flexible and convenient adjustment of the cavity shape. By using different wear-resistant hammers, impact plates, and side liners of the frame, no major adjustments are required. It can quickly respond to the changing requirements of the operation settings, adapt to the best working conditions, improve production efficiency, and produce high-quality particle-shaped products.
