Metal crusher, also known as metal crusher, is a machine for crushing waste metal materials, mainly composed of crusher blade group, bearing box, box bracket, feeding system, power system, electrical control system, etc., through the supporting conveyor, host, unloader, sorting machine to form a complete production line. Metal crusher can deal with various types of metal waste, including cans, paint buckets, waste household appliances, bicycles, auto parts, waste metal furniture, cable and wire, metal pressing block, aluminum profiles, iron sheet, copper products, etc., can remove metal magazines, separate and purify different broken materials, can also choose the appropriate crushing mode according to the nature of the material, Control the size of the broken material to meet different needs.

The 132 metal shredder caters to small and medium-sized industrial crushing needs, suitable for crushing medium-hardness metal materials such as scrap steel, automotive wheels, and thick-walled steel pipes. Equipped with a 15-22kW dual-motor drive system and an upgraded feed port size of 300×350mm, the crushing capacity is increased to 1-3 tons per hour. The hammer head is constructed of high-chromium alloy and reinforced through a special heat treatment process, achieving a hardness exceeding HRC58. This allows for efficient crushing of scrap steel materials under 6mm thick. The innovative "dual-chamber crushing + grading screening" structure meets the pre-processing standards of most metal recycling plants. It also features an intelligent overload protection device that automatically shuts down the machine if it encounters unbreakable hard objects, significantly enhancing operational safety and equipment life.

Scrap steel crushers are generally used to crush scrapped cars, scrapped home appliances, old bicycles and motorcycles, and car shells in batches. The scrap steel materials processed by the scrap steel crusher have high volume specific gravity, high purity, few impurities, and high economic value. The crushed materials can be directly re-melted by the steel mill, with low energy consumption, high output, and very high comprehensive economic benefits.
The scrap steel crusher can separate the rust, paint and other surface dirt on the surface of the scrap steel during crushing, and then under the action of the magnetic separation device, the non-ferrous metals, plastics, rubber and other non-metallic wastes mixed in the scrap steel are piled separately. Not only can pure crushed steel be obtained, but also non-ferrous metals can be recycled through manual selection.

The 200 metal shredder is designed for medium-sized batch crushing applications and is widely used in small and medium-sized scrap steel recycling centers and foundries for metal recycling.

The crushing chamber features a multi-tooth liner design and 12 sets of reversible hammers, achieving a multi-step crushing process of "impact-compression-shearing." Even 10mm thick steel plates can be crushed into shape in one operation. The machine features a hydraulic cover opening, allowing for hammer replacement and chamber cleaning in just 30 minutes, ensuring both efficient production and environmental protection.

The 315 metal shredder is Alva's mid-sized, industrial-grade workhorse, designed for regional scrap recycling centers and steel mill waste processing plants. It's suitable for crushing heavy metal materials such as automobile hulls, machine tool beds, and large pipes. Equipped with a high-power 55-75kW motor and an expanded feed port size of 500×600mm, it can crush 5-8 tons of material per hour. For scrap materials under 15mm thick, the crushed particle size can be adjusted to 30-80mm using a screen, meeting feed standards for blast furnace smelting or electric furnace reuse. The 315 features a one-piece welded frame, offering a 40% increase in load-bearing strength compared to conventional models. Combined with an intelligent temperature control system and automatic lubrication replenishment system, it can operate continuously 24 hours a day, with an overall equipment failure rate of less than 0.5%.

Aluminum scrap crusher is a kind of heavy-duty machinery that is specialized in crushing and recycling various kinds of waste aluminum, aluminum alloy, aluminum scrap, aluminum profiles, and aluminum doors and windows. The application of aluminum scrap crusher provides convenience for the crushing, processing and transportation of aluminum scrap, and greatly improves the recycling efficiency of aluminum scrap. With the continuous improvement of the national economy, the consumption of aluminum scrap resources in various industries has been expanding year by year, and the demand for the production and recycling of aluminum scrap resources has also increased.
