The aluminum sprue and runner crusher is a high-speed hammer crushing machine designed for prepared aluminum foundry returns, including sprues, runners, gates, overflow scrap and rejected castings.
These materials are normally generated during aluminum casting and die-casting production. Their branched shapes, thick junctions and irregular dimensions can occupy considerable storage space and create difficulties during conveying or furnace charging.
The crusher reduces prepared foundry returns into smaller pieces for collection, controlled conveying and return to the remelting process. The machine is intended for classified production scrap with a known material source rather than mixed aluminum collected from recycling yards.
Typical materials suitable for this crusher include:
Aluminum casting sprues
Aluminum runners and gates
Die-casting overflow scrap
Broken casting return material
Rejected aluminum castings
Trimmed aluminum casting waste
Classified foundry returns within the crusher feeding limits
Different alloy groups should remain separated when the foundry needs to preserve alloy composition for remelting. The crusher reduces material size but does not identify or separate aluminum alloy grades.
Aluminum sprues and runners should be inspected before feeding. Steel tools, mold components, trimming blades, bolts and other foreign objects must be removed.
Long branched runners, exceptionally thick junctions and oversized rejected castings may require cutting or separate preparation before entering the crusher. Material dimensions and individual weight must remain within the limits of the selected model.
Hot castings must be cooled to a safe and stable condition before processing. The crusher is not intended for molten aluminum, hot dross, aluminum ash, aluminum powder or material containing unidentified chemicals.
A high-speed rotor drives replaceable hammers to impact, bend and break the aluminum foundry returns inside the crushing chamber. Wear-resistant liner plates protect the chamber surfaces, while the bottom screen grate helps control the maximum discharge size.
Pieces that can pass through the selected screen openings leave the crushing chamber. Oversized material remains inside for continued hammer impact until it is sufficiently reduced.
The discharged material contains a range of piece sizes. Actual output depends on the sprue thickness, runner structure, casting shape, hammer arrangement and screen opening.
The aluminum sprue and runner crusher can operate as an individual machine with suitable feeding and discharge connections. The processed material can be collected in a container or transferred by conveyor according to the foundry layout.
Additional conveying, magnetic inspection or dust collection equipment can be selected separately when required. These auxiliary units are not part of the standard crusher main unit.
This machine is positioned for internal foundry returns generated during casting production. A cast aluminum parts crusher is used for prepared discarded components, dismantled housings and other cast aluminum products collected after manufacturing or service.
Separating these two applications helps match the feeding system, crusher configuration and maintenance requirements to the actual material source.
Aluminum sprues, runners, gates and rejected castings should be classified according to their material source and alloy group before crushing. Mixing different alloy grades may reduce the value of the foundry return material.
The crusher only performs mechanical size reduction. It does not analyze alloy composition or separate different aluminum grades.
The material is inspected for steel tools, mold fragments, bolts, trimming blades and other unsuitable foreign objects. Hot material must be cooled before it enters the crushing area.
Long branched runners and oversized castings may require cutting to reduce bridging at the feed opening. Maximum material dimensions, thickness and individual weight should be confirmed before selecting the crusher model.
Prepared foundry returns are transferred into the feeding hopper by conveyor, loading device or controlled manual feeding according to their dimensions and individual weight.
The material should be supplied at a stable rate. Loading several thick castings or large runner clusters at the same time may cause sudden motor-load changes and unstable crushing.
The drive motor rotates the crusher rotor at high speed. Hammers mounted on the rotor repeatedly impact and break the aluminum sprues, runners and rejected castings inside the crushing chamber.
The material is also subjected to bending and compression between the moving hammers, wear-resistant liner plates and screen grate. Branched runners are shortened and thick junctions are reduced into smaller pieces.
Material that is smaller than the selected screen openings leaves the crushing chamber through the bottom grate. Larger pieces remain inside for continued processing.
The screen opening helps control the maximum discharge size but does not produce completely identical particles. Casting structure, material orientation, thickness and hammer condition all influence the output.
The crushed foundry returns fall from the discharge outlet into a collection container or onto a discharge conveyor. The discharge system should be sized to prevent material accumulation below the crusher.
The processed aluminum can then be stored, conveyed or prepared for furnace charging according to the foundry’s alloy-control and remelting procedures.
When foundry returns may contain small steel attachments, downstream magnetic inspection can be considered after crushing. Magnetic equipment can remove suitable ferrous material but cannot identify different aluminum alloys.
The machine is configured for aluminum sprues, runners, gates, overflow scrap and rejected castings generated during foundry and die-casting production.
A high-speed rotor drives the hammers to break branched runners, thick gate sections and irregular foundry returns into smaller pieces.
Crushing shortens long runner structures and reduces bulky casting returns, making the material easier to collect, store and convey inside the foundry.
The bottom screen grate retains oversized pieces for continued crushing. Different screen openings can be selected according to the required handling and furnace-charging condition.
Hammers, liner plates and screen grates are replaceable wear components. Individual components can be inspected and serviced according to actual operating conditions.
The crusher housing and internal chamber structure are selected according to the runner thickness, casting dimensions, individual weight and expected impact load.
The crusher can be equipped with hydraulic housing-opening assistance to provide access for hammer inspection, liner maintenance, screen replacement and chamber cleaning.
A suitable feeding hopper or conveyor can be selected according to runner length, material shape and required capacity. Controlled feeding helps reduce bridging and sudden load changes.
Rotor dimensions, hammer quantity, motor power and screen opening can be matched to thin casting runners, thick gate sections or rejected casting parts.
The crusher produces smaller and more manageable return material that can improve container loading, conveying and furnace-feeding conditions.
The crusher can be supplied as an individual machine. Feeding conveyors, discharge conveyors and other auxiliary equipment are selected separately according to the workshop arrangement.
The page is limited to prepared aluminum foundry returns. It does not present the machine as a universal crusher for mixed aluminum scrap, engine assemblies, wheels, profiles, cans or aluminum dross.

The feeding opening should accommodate the largest prepared runner cluster. Branched or fork-shaped runners may require cutting when their width prevents stable entry into the crusher.
Thick sprue bases and gate junctions create a higher crushing load than thin runner sections. The maximum local thickness should be provided during model selection.
Rejected castings may be heavier than ordinary sprues and runners. Maximum individual weight affects the feeding method, rotor impact load and required crusher chamber size.
Rotor diameter, rotor width, hammer quantity and individual hammer weight are selected according to the return-material dimensions, thickness and required processing capacity.
The screen opening affects both discharge size and hourly output. Smaller openings keep the material inside the crushing chamber longer and may reduce processing capacity.
The screen should be selected according to storage, conveying and furnace-charging requirements rather than automatically choosing the smallest opening.
A reference output range of 20 to 100 mm may be considered according to the crusher model and screen opening. Actual output contains different piece sizes rather than completely uniform particles.
Actual capacity depends on runner dimensions, sprue thickness, individual casting weight, material bulk density, feeding stability and screen opening.
Thin runner networks and thick rejected castings can produce different hourly outputs on the same machine. Representative material testing is recommended when the material varies substantially between production batches.
A belt conveyor, chain conveyor or loading device can be selected according to runner length, material shape and individual weight. The feeding system should prevent uncontrolled batch loading.
The discharge outlet can be connected to a collection container or conveyor. Sufficient clearance should be provided to prevent crushed material from accumulating below the crusher.
The installation layout should provide enough space for hydraulic housing opening, hammer inspection, screen replacement and removal of internal components.

A reference discharge range of 20 to 100 mm may be considered according to the crusher model and screen opening. Actual output depends on runner structure, sprue thickness, hammer arrangement and feeding condition.
The crusher can mechanically reduce different aluminum alloys, but it does not identify their composition. Different alloy groups should remain separated when the foundry needs to preserve alloy quality for remelting.
No. Aluminum sprues and castings must be cooled to a safe and stable temperature before crushing. Hot material can damage equipment components and create additional operating risks.
Long or heavily branched runners may need to be cut before feeding when their dimensions prevent stable entry into the hopper. Representative material dimensions should be provided before the crusher model is selected.
The crusher is designed for prepared aluminum sprues, runners, gates, overflow scrap, rejected castings and classified foundry returns within the feeding limits of the selected model.
Crushing makes aluminum foundry returns easier to collect, convey and charge, but the processed material should still be checked before remelting. Different alloy grades should remain separated, and steel fragments, mold debris, excessive contamination or other foreign materials should be removed according to the foundry’s furnace-charging requirements.
Please provide material photos or videos, maximum runner dimensions, sprue thickness, individual casting weight, required capacity, expected output size, feeding method, local voltage and available installation space.
The hammers, liner plates and bottom screen grate are the main wear components. Rotor fasteners, bearings and the crushing chamber should also be inspected according to operating hours and material condition.
The crusher only reduces material size. Steel tools, mold fragments and large foreign objects must be removed before feeding. A downstream magnetic unit may recover suitable small ferrous material after crushing.
Prepared rejected castings may be processed when their dimensions, wall thickness and individual weight remain within the machine limits. Oversized or unusually thick castings may require separate preparation.
