Box Crushers (also known as Heavy Hammer Crushers or Square Box Crushers) are versatile mining machines that integrate jaw, hammer and impact crushing technologies into a single high-performance unit. Engineered with optimized wear-resistant design, they drastically reduce hammer abrasion and extend service life--a single set of hammers can process 30,000 to 40,000 tons of stone. They enable direct crushing of oversized raw materials and fully automatic operation, eliminating costly pre-crushing stages and minimizing manual labor. Their core construction includes a heavy-duty frame, rotor assembly, replaceable hammers, adjustable screen plate, impact linears and reliable drive system.
Working Principle:
Box crushers operate with an electric motor driving a high-speed rotor via pulleys and V-belts. The rotor carries hammers that deliver high-velocity impacts to materials entering the crushing chamber from the feed inlet. After initial impact, materials strike the impact liners for secondary crushing, creating a vortex motion that achieves fine crushing through repeated friction, shearing and impact. Crushed materials discharge through svreen plate gaps, with adjustable clearance to control output particle size.
Key Features:
1. Advanced Structural Design
Integrates multiple crushing modes combining jaw and impact crusher functions, eliminating multi-stage crushing processes. High-manganese steel liners and replaceable hammer design enhance wear resistance and equipment service life, with a single set of hammers processing 30.000 to 40,000tons of stone.
2. Superior Performance Efficiency:
Delivers a high reduction ratio of 5-8 with large throughput capacity and low energy consumption. Directly handles raw materials up ti 1000mm in size, eliminating the feed for primary crushing equipment.
3. Intelligent Control System:
Rully automatic feeding and continuous flow operation minimize manual intervention. Hydraulic system enables dynamic adjustment of screen plate clearance to adapt to different material requirements.
Application Fields:
1. Suitable Materials
Medium and low hardness materials: limestone, gypsum, coal, shale, marl;
Ore materials: medium hardness iron ore, copper ore.
2. Industry Coverage
Mining and netallurgy: ore coarse and medium crushing, mineral processing pretreatment;
Building materials and chemicals: cement raw material crushing, construction sand production lines;
Environmental protection and energy: coal fine crushing, solid waste recycling.
