Limestone crushers enhance the processing and utilization of limestone in our country. Limestone is a sedimentary rock mainly composed of calcite. It can be directly processed into stone materials or burned into quicklime. Lime comes in two forms: quicklime and slaked lime. Both lime and limestone are widely used as building materials and are also important raw materials for many industries. In the production of lime, most materials need to be crushed in order to create favorable conditions for the next steps of pre-homogenization, storage, batching, grinding, drying, transportation, etc.
Engineers from Shanghai Shibang Machinery Co., Ltd. remind that there are many factors affecting the material crushing system. Correctly analyzing and mastering these various factors is very important for choosing an economically reasonable crushing system. Since limestone belongs to relatively soft materials, Shibang's impact crusher is the best choice for processing limestone. The crushing chamber of this machine can effectively receive large pieces of material and crush them without compacting the material or causing the crusher to overload.
The geological structure of Ningxia indicates favorable conditions for the formation of energy minerals and non-metallic minerals. Nearly 50 types of useful mineral resources have been discovered in Ningxia, with nearly a thousand locations identified. More than 110 mining sites have D-level reserves or higher. These mineral resources are characterized by large reserves, good quality, and ease of extraction. Resources with abundant reserves include coal, gypsum, limestone, silica stone, and barite. For limestone processing, the preferred equipment is Shibang's impact crusher.
Experts from Shanghai Shibang Crusher point out that the crushing action of the impact crusher on Ningxia limestone involves several processes: The first step is the free crushing stage, where the material enters the crushing chamber and immediately encounters high-speed hammer impacts. The material collides with each other and undergoes friction between the hammer and the material, as well as among the materials themselves, resulting in the pulverization of the material within the crushing chamber (similar to ceramic ball milling). The second step utilizes the high-speed impact of the hammers and the rebound effect of the impact plates, causing the material to repeatedly experience impact forces until it is broken down. Hammers are fixed on a high-speed rotating rotor, and several impact plates are arranged at different angles along the crushing chamber. When the material enters the hammer action zone, it initially experiences the first hammer impact and gets its initial breakage while simultaneously gaining kinetic energy, which propels it at high speed towards the impact plate. After colliding with the impact plate and undergoing further breakage, the material bounces back to the hammer action zone, where it is impacted again by the hammer. This process repeats itself until the material is broken down to the desired particle size and discharged from the machine.
Shibang Crushers promote new leaps in Ningxia's limestone industry! Shibang's limestone crusher (impact crusher) can handle materials with edge lengths below 100-500 mm, with compressive strength reaching up to 350 MPa for various soft and hard ores. The crushed material has a cubic particle shape. Shibang limestone crushers have a simple structure with unique counterattack liners; they are highly efficient and energy-saving when breaking hard rocks, offering comprehensive crushing functions, high productivity, low component wear, adjustable discharge particle size, simplified crushing processes, and cost savings in production, making them the preferred equipment for medium-hardness materials like limestone!
