The box type sand making machine is a heavy-duty box type sand making core equipment specially designed for crushing large raw materials into sand. It adopts the heavy hammer impact crushing principle, combined with a square box type closed crushing cavity and a large torque rotor design, which can directly process large raw stones. The fine sand making of materials is realized through repeated impact and grinding of heavy hammers in the cavity without pre-coarse crushing process. The equipment can process hard and soft materials such as river pebbles, granite, basalt and construction waste. The finished sand has regular particle shape and reasonable gradation, meeting the national standard of manufactured sand requirements. It is suitable for sand production plants, mine crushing, infrastructure engineering and other scenarios, with the advantages of large feed size, high crushing ratio and stable operation, and is the preferred equipment for sand making of large raw materials.

Product Advantages & Technical Highlights
Large feed inlet design: Can directly process large raw stones without pre-coarse crushing equipment, reducing processes and investment.
Suitable for both hard and soft materials: Heavy hammer + thick-walled crushing cavity with strong impact crushing force, efficient processing of river pebbles, granite, construction waste, etc.
Ultra-high crushing ratio: Fine sand making of large materials can be completed with one feeding, the crushing ratio can reach 50:1, greatly improving sand making efficiency.
Wear-resistant and durable: Hammers and liners are made of high chromium alloy wear-resistant material, with strong impact resistance and wear resistance, greatly extending the service life of wearing parts.
Convenient and efficient maintenance: Side door/upper flip cover design, no large hoisting equipment needed, easy replacement of wearing parts, shortening downtime for maintenance.
Applicable Scenarios & Materials
Sand production plants: Direct sand making of large river pebbles, granite, basalt, limestone and other raw stones, eliminating the coarse crushing link and reducing production investment.
Mine crushing field: Fine sand making of large mine ores, connecting the subsequent mineral processing or building materials production process, improving ore utilization rate.
Infrastructure engineering projects: On-site sand making for roads, bridges, real estate projects, processing large raw materials nearby, saving raw material transportation and coarse crushing costs.
Solid waste recycling: Crushing and sand making of large construction waste, ore tailings, cement blocks, etc., realizing secondary resource utilization and balancing benefits and environmental protection.
