Crushing and screening equipment FAQs
01. What information is needed to review equipment selection?
Provide material type, feed size and moisture, target throughput, product grading and site conditions. For an existing line, include the equipment list and any operating constraints.
02. Is machine throughput the same under all conditions?
No. Feed properties and grading, moisture, machine settings and overall line conditions influence actual throughput. Proposed capacity needs to be assessed for the project material and conditions.
03. At which stage is a jaw crusher considered?
A jaw crusher is commonly considered for primary crushing. Suitability depends on feed size, rock properties and the requirements of the next stage, and should be reviewed within the complete line.
04. What determines impact crusher selection?
Material hardness and abrasiveness, feed size, product shape and grading, and wear-part conditions are selection factors. One model is not suitable for every rock type and crushing stage.
05. How are screen type and deck arrangement selected?
The review considers material flow, number of products, cut sizes, material shape and moisture, and installation conditions. Screen area and media are selected after these requirements are defined.
06. Does every aggregate line need washing and water recovery?
The requirement depends on clay and fines content, product-quality requirements and water constraints. Washers, dewatering equipment and water-recovery circuits should be selected following feed and process assessment.
07. What infrastructure is needed before installation?
Installation drawings and dimensions, foundation requirements, electrical supply, transport and service access, and connections to other equipment need review. Exact project requirements are defined in the relevant technical documentation.
08. What should I provide for a spare-parts enquiry?
Send the machine model, identification number or nameplate photograph, part name and photographs, and operating details. For wear parts, material type and operating time also help the compatibility review.

Installation, spare parts and project terms
09. How are price, delivery time and service terms determined?
They depend on the model, specifications, scope of supply and project conditions, and are defined in the formal proposal or contract. General website information does not replace a project-specific quotation and written terms.
10. Can a single machine be reviewed for an existing line?
Yes. A single-machine review still needs to consider the capacity and conditions of upstream and downstream equipment. Provide the current line details and the objective of the change so compatibility can be assessed.
11. What is considered in a line layout?
Material and recirculation routes, elevation differences, stockpile locations, maintenance access, transport space and site constraints are considered. The final layout needs to be coordinated with site information and drawings.
12. Which guidance should be used for safe operation and maintenance?
Use the instructions for the specific model and the machine handover documentation. For service or parts questions, provide the machine details. Before intervention, responsible personnel must follow the site’s safe shutdown and energy-isolation procedures.
