The Zhongyu Dingli 600 TPH Dolomite Processing Line integrates primary crushing, shaping, screening and sand making within a fully enclosed production environment on a 30 mu site. The crushing system uses one set of DLPCZ1815 Heavy Hammer Impact Crusher for primary reduction of raw dolomite, followed by one set of DLPC1220 Shaping Crusher for secondary particle shape refinement and size control. The DLYKZ Vibrating Screen provides multi-stage precision classification of finished aggregates into various construction-grade specifications. The DLZSJ Double Rotor Sand Making Machine processes fine dolomite fractions into high-quality manufactured sand with controlled gradation and cubical geometry. The production line is managed by a Mining Production Management System and a Sand and Aggregate Purchase, Sales and Inventory Management System, enabling real-time digital monitoring of the entire production workflow from raw material input to finished product output and inventory tracking. The total project investment is RMB 50 million, of which RMB 10 million is allocated to environmental protection infrastructure. All crushing, screening and sand making processes operate within a sealed enclosure, effectively containing dust and noise emissions throughout the production cycle.
Dolomite is a widely used construction raw material for concrete aggregate, road base and building material production, but its processing presents specific challenges in dust control and noise management, particularly for plants located near residential or environmentally sensitive areas. Conventional open or semi-enclosed dolomite crushing operations generate significant airborne dust and noise pollution, creating compliance risks under increasingly strict environmental regulations. The Zhongyu Dingli 600 TPH Dolomite Processing Line addresses this through a fully enclosed production design in which all crushing, screening and sand making stages operate within sealed structures, eliminating open dust emissions and containing noise at the source. The line further differentiates itself through intelligent digital management, with a Mining Production Management System providing real-time operational data on equipment status, throughput and energy consumption, and a Sand and Aggregate Purchase, Sales and Inventory Management System enabling automated tracking of product output, customer orders and stockpile levels. This dual-system integration transforms the production line from a conventional crushing operation into a digitally managed smart plant, improving operational efficiency, reducing manual oversight and providing data-driven decision support for production scheduling and sales management. With a total investment of RMB 50 million including a 20% allocation to environmental protection, the project demonstrates that high-capacity dolomite processing and stringent environmental compliance can be achieved simultaneously.
Raw dolomite blocks are delivered to the primary hopper by mining trucks and fed uniformly into the DLPCZ1815 Heavy Hammer Impact Crusher for initial size reduction, breaking large raw ore into intermediate-sized fragments suitable for further processing. The primary crushed material is conveyed by belt to the DLPC1220 Shaping Crusher for secondary impact shaping, which refines the particle geometry and reduces the needle-like content in the crushed aggregate. Shaped material passes to the DLYKZ Vibrating Screen for multi-stage classification, separating the output into various construction aggregate specifications according to project requirements. Oversize fractions that do not meet the target specification are returned to the Shaping Crusher in a closed-loop circuit for reprocessing. Fine dolomite fractions are directed to the DLZSJ Double Rotor Sand Making Machine, where dual-rotor high-speed impact produces manufactured sand with consistent fineness modulus and cubical particle shape. The finished aggregates and manufactured sand are conveyed to designated stockpiles, while all dust generated during crushing, screening and sand making is captured within the sealed enclosure and collected by the integrated dust suppression system. The Mining Production Management System monitors each stage of the process in real time, tracking material flow, equipment load and output volumes to maintain stable 600 TPH production throughout continuous operation.
Zhongyu Dingli delivers full EPC turnkey services for the 600 TPH Dolomite Processing Line from initial design through long-term operational support. In the engineering design phase, the technical team evaluates dolomite material properties, site conditions and the fully enclosed production requirement to design the optimal equipment layout, sealed enclosure structure and intelligent management system integration within the 30 mu site plan. During manufacturing, all core equipment including the DLPCZ1815 Heavy Hammer Impact Crusher, DLPC1220 Shaping Crusher, DLYKZ Vibrating Screen and DLZSJ Double Rotor Sand Making Machine is produced in-house with strict quality and wear-resistance testing, and the Mining Production Management System and Sand and Aggregate Purchase, Sales and Inventory Management System are configured to the project's specific operational and commercial requirements. For installation and commissioning, Zhongyu Dingli engineers supervise the complete construction sequence including sealed enclosure installation, equipment assembly, belt conveyor integration, dust suppression system setup, intelligent management system deployment and full-load performance verification at 600 TPH. In the operations and maintenance phase, the company provides remote monitoring through the intelligent management platform, scheduled preventive maintenance, wear part supply and ongoing system optimization to ensure the production line maintains stable output and environmental compliance throughout its operational life.
The 600 TPH dolomite processing project demonstrates the successful integration of high-capacity crushing and sand making with intelligent digital management and fully enclosed environmental design within a single production facility. The total project investment of RMB 50 million includes RMB 10 million dedicated to environmental protection, representing a 20% environmental investment ratio that reflects the project's commitment to sealed-process operation and comprehensive dust and noise control. The DLPCZ1815 Heavy Hammer Impact Crusher and DLPC1220 Shaping Crusher combination has been verified across multiple dolomite and similar soft rock processing projects to deliver consistent throughput with uniform particle shape and low powder generation. The DLZSJ Double Rotor Sand Making Machine produces manufactured sand with stable gradation that meets construction industry standards for concrete and mortar applications. The Mining Production Management System provides plant operators with real-time visibility into production capacity, equipment health and energy consumption, while the Sand and Aggregate Purchase, Sales and Inventory Management System enables precise tracking of product output and commercial distribution, improving operational decision-making and reducing inventory management costs compared to conventional manual tracking methods.
Q1: What are the advantages of a fully enclosed design for a dolomite processing line? A fully enclosed design contains all dust and noise emissions within sealed structures during crushing, screening and sand making operations, eliminating the open dust generation that is typical of conventional aggregate plants. This is particularly important for dolomite processing sites located near residential areas or within environmentally regulated zones, where dust and noise limits are strictly enforced. The enclosed design also enables more efficient dust collection through centralized pulse dust collector systems, achieving dust emission levels well below regulatory thresholds. Additionally, the sealed environment protects equipment from weather exposure, reducing corrosion and maintenance requirements while extending the service life of critical components.
Q2: How does the Mining Intelligent Management System improve production line operations? The Mining Production Management System provides real-time digital monitoring of equipment operating status, throughput rates, energy consumption and production output across all stages of the dolomite processing line. This eliminates the reliance on manual observation and periodic reporting, enabling operators to identify and respond to production bottlenecks, equipment anomalies and capacity deviations immediately rather than after the fact. The Sand and Aggregate Purchase, Sales and Inventory Management System complements this by tracking finished product stockpiles, customer orders and delivery schedules in real time, allowing the plant to align production output with sales demand and avoid overstocking or supply shortages. Together, these systems reduce manual operation intensity, improve production scheduling accuracy and support data-driven decision-making for plant management.
Q3: Why is the DLZSJ Double Rotor Sand Making Machine selected for dolomite manufactured sand production? The DLZSJ Double Rotor Sand Making Machine uses dual high-speed rotors to deliver multiple impact events on each dolomite particle as it passes through the crushing chamber, producing manufactured sand with consistently cubical particle shape, controlled fineness modulus and low powder content. Compared to single-rotor designs, the dual-rotor configuration achieves higher sand production efficiency and better particle shape with fewer passes through the machine, reducing energy consumption per ton of manufactured sand output. This is particularly effective for dolomite, which has moderate hardness and responds well to high-speed impact shaping, making the DLZSJ an optimal match for producing high-quality manufactured sand that meets concrete and mortar application standards.
