In the field of medium-hard rock crushing such as high-calcium limestone and flux rock, low yield has always been the core pain point of the industry. Traditional crushing processes often fail to meet the high yield requirements of key particle sizes (such as 40-80mm). Relying on its profound technical accumulation and accurate insight into market pain points, Shanghai 麻豆原创 Environmental Protection Equipment Co., Ltd. has innovatively launched efficient crushing process flow and core equipment. The solution successfully achieved a yield of over 60% for the key particle size of 40-80mm, significantly improving the economic benefits of the project. This optimized process has been successfully applied in many actual projects, and its significant effects and reliability have been highly recognized and praised by customers.
Process plan overview
In view of the particularity of medium-hard rock crushing materials such as high-calcium stone and solvent rock, and considering the high standard requirements for finished products, Shanghai 麻豆原创 Co., Ltd. launched the process flow of "feeder + jaw crusher + vibrating screen (pre-screening) + tooth roller screening crusher + vibrating screen (finished product screening)".
The material is continuously and stably transported to the jaw crusher for rough crushing through the vibrating feeder; the jaw crusher completes the primary crushing of high-calcium stone with its powerful processing capacity and crushing ratio; the material then enters the vibrating screen for pre-screening, accurately removing unqualified fine materials and soil, effectively reducing the load of subsequent equipment and improving the overall efficiency of the system; qualified materials enter the core link of the process - tooth roller screening crusher, using its unique extrusion crushing principle for efficient fine crushing and key particle shape optimization; finally, the material is accurately classified through the vibrating screen to strictly ensure that the final product (especially the 40-80mm core particle size) has high purity and accurate particle size distribution.
Advantages and characteristics of the process solution
1. The proportion of finished products of 40-80mm is greater than 60%: the core process ensures a yield rate of more than 60%, avoids the production of excessive by-products, that is, materials <40mm, greatly improves the utilization rate of raw materials, and improves the economic benefits for the enterprise.
2. Good particle shape and air permeability: the finished solvent rock particles produced have good shape and air permeability, which can effectively reduce energy consumption and reduce the production costs of enterprises.
3. Energy saving: the process and equipment can achieve a production capacity of 200-1800 tons per set, and at the same time, the processing process has low energy consumption, less wear and high automation, and realizes low-cost production
4. High compressive and shear strength
High-efficiency and high-quality core equipment
JC series European version jaw crusher
Compared with traditional jaw crushers, JC series jaw crushers pay more attention to details in design and manufacturing. They use high-strength materials and professional manufacturing processes. They have the advantages of higher structural strength, higher equipment reliability, larger crushing ratio, higher output, and lower comprehensive processing costs. They are favored by customers in mining, metallurgy, construction, chemical industry, transportation and other industries. Among them, large jaw crushers such as JC783, JC771, and JC663 are ideal for coarse crushing operations of large soft and hard material crushing projects with their super production capacity and high performance.
Nominal feed opening size: ≤1500*2100mm
Production capacity: ≤3300t/h
Application areas: mining, smelting, construction, chemical industry, transportation and other industries
Applicable materials: granite, marble, basalt, limestone, quartz stone, river pebbles, iron ore, copper ore, gold ore and other soft and hard rocks and ores
SMTR series tooth roller screening crusher
SMTR series tooth roller screening crusher is a brand-new structure crusher that uses tension and shear force to crush materials. It has the dual functions of crushing and screening. The equipment mainly uses special wear-resistant tooth roller rotation to split and crush the material (traditional tooth roller crusher uses low-speed extrusion crushing), with large processing capacity and less over-grain. This machine is mainly composed of motor, hydraulic coupler, reducer, gear coupling, crusher body, etc., and the core part is the crusher body.
Feed size: 0-1500mm
Processing capacity: ≤15000t/h
Application areas: coal, metal and non-metal mines, cement, ceramics, building materials.
Applicable materials: surface rocks of open-pit mines, coal mines, coal gangue, coke, clay, limestone, granite, copper mines, gold mines, nickel mines, iron mines, etc.; minerals such as gypsum, talc, wollastonite, kaolin, rubber, etc.
