1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate production margins? For plant managers overseeing sand and gravel extraction, key challenges persist: inconsistent feed material degrading final product specification, excessive wear on components from abrasive particulates leading to unplanned maintenance stops, and inefficient water or dust management creating environmental compliance risks. Each hour of unscheduled downtime can cost thousands in lost production and contract penalties. How do you increase throughput while controlling the total cost of ownership? Is your current processing line flexible enough to handle variable deposit geology without sacrificing yield? The solution requires equipment engineered not just for capacity, but for durability, precision, and operational stability in the most demanding pit and quarry conditions.

2. PRODUCT OVERVIEW

This product line comprises CE Marked stationary and mobile sand gravel mining makers—comprehensive processing plants designed for the primary crushing, screening, washing, and stockpiling of aggregate materials. The operational workflow is engineered for continuous, highvolume output: (1) Feed material is uniformly introduced via vibrating grizzly feeders to a robust primary crusher. (2) Crushed aggregate is then conveyed to a multideck screening unit for precise classification into specified grades. (3) Where required, sand fractions are routed through integrated cyclones or screw classifiers for washing and dewatering to meet strict cleanliness standards. (4) Sized and washed product is conveyed to designated stockpiles. (5) Integrated control systems monitor the entire process. These systems are suited for greenfield sites, existing plant upgrades, or temporary contract mining projects. Limitations include a requirement for competent site planning for stationary plants and defined feed size parameters as per model specification.

8. FAQ

Q1: What does the CE Mark specifically guarantee about this equipment?
A1: The CE Mark confirms the machinery meets all applicable EU health,safety,and environmental protection directives.It verifies compliance with the Machinery Directive(2006/42/EC),Electromagnetic Compatibility Directive(2014/30/EU),and often the Pressure Equipment Directive(2014/68/EU),ensuring it can be legally placed on the market within the European Economic Area.

Q2: How does this plant handle particularly hard or abrasive rock types like granite or quartzite?
A2: For such applications,a specific "Hard Rock" configuration is recommended.This includes jaw crushers with optimized kinematics,a heavierduty cone crusher liner profile,increased wear liner thickness at transfer points,and upgraded screen mesh fastening systems.All specifications are reviewed during project engineering.

Q3: What is the typical lead time from order to delivery?
A3: For standard configured models,the lead time is typically between 1216 weeks.Customengineered solutions require detailed specification review,but our modular approach often allows delivery within1822 weeks.Delivery schedules are confirmed upon order finalization.
