As the core component of crushing equipment, the design of BHS crusher throwing head is directly related to the adaptability and crushing efficiency of the equipment to different materials. Through key technologies such as material selection, structural optimization, dynamic adjustment and wear-resistant treatment, BHS throwing head can efficiently cope with complex working conditions such as high-hardness ore, construction waste, wet and sticky materials and metal waste, and meet the diversified needs of industries such as mining, building materials, metallurgy and environmental protection.
For high-hardness materials (such as granite and basalt), BHS throwing head adopts a composite structure of cemented carbide and high-manganese steel. The cemented carbide strip is embedded in the metal matrix through an arc design, which significantly improves the impact resistance and wear resistance. For medium and low hardness materials (such as limestone and shale), a high-carbon steel matrix is selected with surface surfacing technology to ensure cost-effectiveness and extend the service life.
The arc groove design of the throwing head increases the effective working area, so that the material can obtain a more uniform impact force distribution during the crushing process. For example, when processing ore with high quartz content, the curved carbide strip can avoid the risk of fracture caused by stress concentration of traditional slender strips, while reducing the non-working surface area and energy consumption.
According to the characteristics of different materials, BHS crusher can adjust the speed of the throwing head in real time through the intelligent control system. For example, when processing high-hardness materials such as iron ore, the low-speed high-torque mode is adopted to avoid equipment overload due to excessive speed; when crushing sticky materials such as wet coal and clay, the medium-speed operation is combined with the optimized tooth shape design to prevent the accumulation of materials in the crushing chamber.
The surface of the BHS crusher throwing head adopts a composite process of heat treatment and surfacing. For example, after the high-manganese steel matrix is treated with water toughening, a high-hardness alloy layer is surfacing to increase its wear resistance by 2-3 times. For materials containing metal impurities such as construction waste, the edge of the throwing head is designed as a replaceable wear-resistant block to reduce maintenance costs.
For high-moisture materials such as wet coal and clay, the BHS throwing head combines special tooth design with speed regulation, such as the combination of "helical teeth + low-speed rotation", which reduces material slippage while using centrifugal force to throw moisture out of the crushing chamber to ensure crushing efficiency.
In the field of scrap metal recycling, the throwing head optimizes the impact angle and kinetic energy distribution, such as increasing the mass of the hammer by 30% to cope with metal deformation resistance, and adopts an adjustable rotor design to meet the crushing needs of metal plates of different thicknesses.
BHS crusher throwing head has been widely used in mining, building materials, environmental protection and other industries. Its modular design supports the rapid replacement of carbide bars and wear-resistant blocks of different specifications. For example, when processing silicate materials (such as glass and ceramics), the surface hardness and impact speed of the throwing head can be adjusted to achieve integrated operations from coarse crushing to fine crushing.
BHS crusher throwing head has successfully built a "one machine, multiple uses" crushing solution through the deep integration of material innovation, structural optimization and intelligent control technology. Its core technology not only breaks through the bottleneck of traditional equipment in processing high-hardness materials, but also demonstrates significant advantages in special working conditions such as wet and sticky materials and metal waste, providing key support for the efficient development of the global mining and environmental protection industries.
