To choose a vacuum loader for a crusher production line, start with the material leaving the crusher and the amount your process must transfer—not with a motor size or catalogue headline. Record the regrind’s form, bulk density, moisture, required throughput, route length, lift height, and destination, then ask suppliers to size a system against those conditions. Crusher output can include irregular flakes, fines, and dust, so the pickup, filter, receiver, and discharge arrangement all matter. At Tuojie, we recommend sharing a process layout and material sample or material data before comparing equipment proposals.

Begin with the crusher’s expected output and the downstream equipment’s consumption rate. The loader should transfer enough material to keep the next process supplied without relying on an unverified catalogue capacity. If the crusher produces in batches or runs intermittently, tell the supplier how those operating periods affect the average and peak demand.
For example, a buyer might use an initial design case of 100 kg/h to organize a quotation request. This is an illustrative planning figure, not a recommended capacity for every crusher line or a performance claim. Replace it with your measured or specified process requirement, and ask the supplier to state the material and route conditions used to assess the proposed rate.
Clarify whether the regrind will travel to a storage hopper, mixer, dryer, or another machine. Include the required discharge method and whether the receiver must feed the next operation continuously or in cycles. Also note how many pickup points the system must serve and whether they operate at the same time.
Crusher output is not always uniform. Depending on the feedstock and screen arrangement, it may contain a mix of larger flakes and fine particles, and its flow behavior may differ from that of new pellets. Provide the material name, approximate particle-size range if known, bulk density, temperature, and any tendency to cling, bridge, or generate dust.
Bulk density is important because conveying equipment moves a volume of material while production targets are usually stated by weight. If density changes between materials or batches, a system selected for one product may not deliver the same mass rate for another. Where possible, provide measured values and explain how they were obtained rather than relying on a generic material label.
Moisture can affect flow and may cause material to adhere to internal surfaces or filters. Tell the supplier if regrind can include labels, metal fragments, or other contaminants, and explain what upstream separation is already in place. Abrasive particles may also influence contact surfaces and maintenance needs, so include any known wear concerns in the specification.
Draw the route from the crusher pickup point to the receiver and mark horizontal distance, vertical lift, bends, hose sections, and changes in pipe diameter. A sample layout might include 8 m of horizontal conveying distance, but that figure is only an example for documenting a route—not a universal limit or a guarantee of capacity. Include the actual arrangement in your request so suppliers can assess the combined effect of the path and the material.
More bends or a longer route can change conveying resistance and may affect the system selected. A straight-line distance between machines does not show the full path, so measure along the intended pipe route. If the layout is still being designed, provide the available floor plan and identify any fixed constraints.
Ask suppliers to explain the proposed vacuum source, receiver, filter, discharge device, and conveying line as one system. Confirm that the receiver volume and discharge arrangement suit the downstream process and that the filter is appropriate for the fines expected from the crusher. If the line handles more than one material, clarify how changeover, residue removal, and filter cleaning will be managed.

Crusher lines can produce airborne dust, so include housekeeping and operator exposure considerations in the design review. Ask where filtered air is discharged and what routine inspection or cleaning the system requires. Do not assume a standard filter or enclosure will meet every site’s dust-control requirements; confirm the relevant requirements with your safety and engineering teams.
Describe how the loader should start, stop, and communicate with the crusher and receiving equipment. The control sequence may need to respond to receiver level, downstream demand, or a production-line interlock. Specify the required power supply and control interface, and ask the supplier to identify any equipment or wiring that is outside the quoted scope.
Request proposals using the same material, route, production target, and operating pattern. A quoted capacity is difficult to compare unless its test or design conditions are clear. Ask each supplier to list assumptions, included components, utilities, installation requirements, and exclusions.
Also compare access for filter maintenance and inspection. A compact arrangement may be difficult to service if the receiver is installed under a low ceiling or near other machinery. Ask for a general arrangement drawing or installation dimensions before finalizing the location.
Motor power does not, by itself, confirm that a loader will deliver the required material rate through your specific route. Capacity depends on the material and system conditions, so request an application-based proposal rather than selecting from one electrical specification. Compare the complete configuration and the assumptions behind the stated performance.
A proposal based only on the largest particles may overlook the fines produced during crushing. Fine material can influence filter selection, cleaning frequency, and dust management. Share representative material information and ask how the proposed system handles the fine fraction.
Late changes to route, receiver position, or control requirements can affect equipment selection and installation planning. Confirm these details before purchase where possible. If the layout is not final, clearly identify provisional dimensions and ask what must be reconfirmed before manufacture.
Prepare one concise application sheet with the target rate, material description, route drawing, operating schedule, receiving equipment, and site utilities. Where material properties are uncertain, ask whether a sample review or a site-specific validation step is appropriate before placing an order. This helps turn a broad request for a vacuum loader into a proposal that can be checked against your production needs.
At Tuojie, we can review the application details with your team and discuss a suitable vacuum loader configuration for a crusher line. Share the material being conveyed, required transfer rate, route dimensions, and receiving point when requesting a quotation. We can then identify missing information and clarify the assumptions needed for a responsible equipment recommendation.
The right vacuum loader for a crusher production line is the one sized for the actual regrind, required throughput, conveying route, and downstream process. Start by documenting those conditions, then compare complete system proposals rather than isolated specifications. Before purchase, confirm filtration, discharge, controls, maintenance access, and installation interfaces with the supplier. Send Tuojie your process details and layout to begin a focused review of your vacuum loader requirements.
