Engineered for superior reliability, high output performance, and severe-duty applications.
In modern aggregate production and mineral processing, traditional hammer mills often struggle with high-moisture inputs. High-moisture raw materials, such as wet coal, clay, and damp limestone, frequently clog traditional screen bottom grates, forcing operators to deal with costly unscheduled downtime. The development of the Hammer Crusher Without Screen represents a major engineering breakthrough, offering an unhindered discharge path that eliminates clogging risks and delivers consistent production rates under challenging conditions.
Industrial operations worldwide are shifting toward heavy machinery setups that require minimal maintenance. In rapidly industrializing territories across Africa, Central Asia, and Southeast Asia, screenless hammer mill installations are now standard for coal-fired power stations, brick manufacturing lines, and mining operations. By removing the physical grate screen, these machines process materials with water content exceeding 15% without reducing throughput.
Additionally, the growth of small-to-medium mining enterprises has created strong demand for diesel-driven mobile hammer mill setups. These mobile units offer the independence needed to run high-capacity crushing operations in remote locations without access to a stable electric grid.
Three primary factors are driving the adoption of screenless hammer mills: energy efficiency, reduced component wear, and process simplification. Removing the screen grates significantly reduces internal friction and heat buildup, leading to longer service life for the hammerheads and liner plates. High-chromium alloy hammers and reversible rotor shafts also allow operators to double the wear cycle before needing replacement parts.
Modern aggregate facilities are also increasingly integrating these crushers directly with wet processing mills and downstream sorting machinery. This integration simplifies production lines by eliminating the need for pre-drying steps.

Ascend has developed steadily since its establishment. Our business covers more than 130 countries and regions around the world, especially in Africa and Southeast Asia. Ascend machine quality and after-sales service have won widespread praise from international customers.
Different regions present unique geological conditions and material behaviors. A one-size-fits-all approach to crushing often leads to operational bottlenecks. Understanding the exact material characteristics is key to selecting the right machinery.
In industrial power plants and processing facilities, wet coal feed stocks often cause issues for traditional screen-grated crushers. Screenless hammer mills bypass the screen stage entirely, using impact energy to reduce particle size to the required mill feed specification without clogging.
For soft-to-medium hard rocks like limestone, soft dolomite, and shale, screenless crushing systems offer a reliable first-stage or second-stage reduction path. Removing the screen grates increases product flow rates and keeps dust generation within manageable limits.
In mineral recovery regions, screenless hammer mills provide pre-crushing preparation before materials move to wet pan mills. This process ensures the feed size is optimized for panning and grinding tables, reducing overall wear on the machinery.
Explore the technical capabilities and design engineering behind our leading heavy-duty equipment configurations.
Impact crushers use rapid dynamic impact forces to fracture materials along their natural planes of weakness. This equipment features high reduction ratios, easy maintenance, and excellent efficiency, producing highly cubic aggregates. Design details include three crushing chambers, a seamlessly connected rotor, wear-resistant blow bars, and user-friendly hydraulic or screw opening mechanisms.
These crushers perform reliably in all sizing stages, from primary stone processing to final product shaping.
