Crushers have been used in concrete and demolition (C&D) recycling applications for over 20 years. Recycling applications use fixed plant, jaw crushers, cone crushers, screens, etc, to recycle C&D materials into products that can be reused in construction and domestic applications. From fixed plants, mobile (tracked and wheeled) crushing systems were …

Asphalt, concrete, granite, sand, slate; Block, brick, ceramic tile, roof tiles; Grout, joint compound, mortar; Pavers, siding, terrazzo; Many types of operations can create airborne silica dust from these materials, which can be hazardous if inhaled. Common construction operations that can increase the risk of silica exposure include:
concrete, brick, and mortar. When workers cut, grind, drill, or crush materials that contain crystalline silica, very small dust particles are created. These tiny particles (known as "respirable" particles) can travel deep into workers' lungs and cause silicosis, an incurable and sometimes deadly lung disease.
Construction and Demolition Debris Recycling. Reusing and recycling construction and demolition (C&D) materials can be more economical than disposal. Common materials include: Lumber. Drywall. Metals. Masonry …
• Bricks, concrete, rock and other masonry material; and • Landscape material. C&D debris comprises a significant waste stream.

C&D waste is crushed in the plant and made into bricks, drainage slabs, concrete blocks, paving blocks, etc. The cost of recycled materials is 10–12% less than that of normal materials (Paul et al. 2018 ).
C&D waste is made up of wood, steel, concrete, gypsum, masonry, plaster, metal, and asphalt. C&D waste is notable because it can contain hazardous materials such as asbestos and lead. Estimates vary, but a commonly accepted estimate is that between 15% and 20% of municipal solid waste comes from construction and demolition projects.
C&D materials included in the report are steel, wood products, drywall and plaster, brick and clay tile, asphalt shingles, concrete, and asphalt concrete. The generation estimates represent C&D material amounts from construction, renovation and demolition activities for buildings, roads and bridges, and other structures.
In all cases where concrete is being smashed or size-reduced, demolition workers and crushing plant operators are breaking down materials with crystalline silica dust as a percentage of the particulate matter in part …
I need some advice, Mobile Jaw or Impact crusher.

A promising practice to utilize C&D wastes is crushing and sieving them into recycled aggregates to replace natural sand and stones. In China, with the development of this industry within the past ten years, the ratio is less than 10%. However, the recycling ratio of C&D wastes in most developed countries can reach over 90% [1], [2]. On one ...
