A mobile impact crusher is a mobile crusher centered around an impact crusher. It serves as secondary crushing equipment, typically following a primary jaw crusher. Key advantages include high crushing efficiency, comprehensive functionality, and superior product quality. Thanks to a compact and well-engineered design, Sandreck’s mobile impact crushing plants can meet the requirements for crushing and screening materials across coarse, medium, and fine size ranges.

These mobile impact crusher plants feature an integrated design that combines crushing and screening systems into a single unit. Equipped with either a wheeled chassis or a tracked undercarriage, they support hybrid diesel-electric drive systems and require no permanent foundation. They offer high mobility and a small turning radius. They are primarily used in applications requiring mobile crushing, such as mining, construction waste processing, and transport infrastructure projects. These units can operate independently or in conjunction with a jaw crusher to form a closed-circuit processing loop, with a maximum processing capacity of up to 650 t/h.

Mobile Impact Crusher Working Principle

The operating principle of a mobile impact crushing plant generally follows a material processing sequence of “primary crushing – secondary/fine crushing – screening.” Material is fed uniformly into the stone crusher by a vibration feeder, where it undergoes initial impact crushing. The crushed material then passes through a circular vibrating screen, forming a closed-circuit system. Material that does not meet the required particle size is returned to the impact crusher for further processing, while the finished product—meeting the specified size requirements—is discharged via a belt conveyor, enabling a continuous crushing operation.

A mobile impact crusher plant can be configured as a combination of “feeder + impact crusher + vibrating screen” or simply “impact crusher + vibrating screen,” depending on specific production requirements.

Types of Mobile Impact Crushing Plants

Based on their mobility mechanism, mobile impact crushers are primarily categorized into two types: tire-mounted (wheeled) and crawler-mounted (tracked) units.

Tire-mounted mobile impact crusher plants are towed by a truck tractor. They are typically used for processing construction waste in urban areas or in operations that require frequent relocation. While these units require relatively flat ground for travel, they do not demand a large operational footprint.
Wheeled mobile impact crushers feature a compact design, a high chassis, and a small turning radius, facilitating both road transport and access to confined work sites. They are suitable for processing materials of low to medium hardness, such as limestone, granite, and construction waste.

Crawler-mounted mobile impact crushing plants are fully automated. Their tracks are driven by a hydraulic system and can be operated via remote control. Thanks to their superior traction and substantial weight, these units can navigate slopes and rugged terrain, making them ideal for operations on hillsides or uneven ground. They are frequently employed in sectors such as metallurgy, chemicals, construction materials, and hydropower—industries that often require equipment relocation—and are particularly well-suited for mobile stone-processing tasks associated with highway, railway, and hydroelectric infrastructure projects.
Tracked mobile impact crushers utilize a hybrid diesel-electric drive system for their crawler chassis, ensuring convenient relocation and versatility across a wide range of operating conditions. They are capable of processing various materials, including coal gangue, sand and gravel, basalt, river pebbles, construction waste, and various types of ore.

Depending on the type and scale of the raw materials being processed, as well as the requirements for the finished products, users can adopt different methods of mobility.

Features of Mobile Impact Crusher Plant

• Mobile impact crushers enable on-site material crushing, eliminating the need to transport materials off-site for processing and significantly reducing transportation costs.
• The integrated design minimizes the need for on-site infrastructure, thereby lowering both material and labor requirements. Its compact and efficient layout offers greater flexibility for site deployment.
• Whether for primary crushing, fine crushing, or screening, these mobile impact crushing plants can operate as standalone units or be configured to work in combination with other equipment.
• Equipped with an intelligent PLC control system, the unit allows users to operate and monitor operations remotely, with the ability to adjust running parameters at any time.
• These mobile impact crusher plants are highly convenient for deployment at construction sites.

Mobile Impact Crusher Applications

① Mobile impact crushing stations are widely used in the recycling of construction waste, as well as in specialized projects requiring mobile stone-crushing operations, such as those for hydropower, expressways, and railways.
② Depending on their mobility system—wheeled or tracked—these mobile impact crushers are suited for various operating environments, ranging from urban construction waste processing to flat terrain, mountainous areas, or rugged landscapes.
③ Mobile impact crusher plants can also be utilized for the artificial production of sand from materials such as river pebbles, basalt, granite, ore tailings, and coal gangue.
