Applicable materials:Construction waste, milling material, silicate, coal gangue, coal, coke, asphalt lumps, calcined coke, glass, limestone, silica stone, silicon-manganese alloy ore, ceramics, etc.
Project Location: Pyrite Concentrator Plant
Raw Materials: Pyrite slag and associated sulfur raw ore with sulfur content ranging from 12% to 16%
Production Line Capacity: 180 tons per hour crushing and separation production line for sulfur concentrate sand
Core Equipment: Huashengming 1210 double toothed roller primary crusher + Huashengming 1210 hydraulic double roller fine crusher

Processing Purpose: After crushing, materials enter jig gravity separation to separate high-purity sulfur concentrate sand and raise the recovery rate of sulfur resources

Sulfur Concentrate Sand Crusher
Pyrite is brittle and adhesive due to sulfur content. Ordinary crushers easily suffer from bin blockage and roller adhesion, requiring frequent shutdown cleaning and reducing overall production capacity.
Uniform particle size is required for finished sulfur concentrate sand. Excessive fine crushing leads to loss of fine pyrite particles and lower output of separated finished products.
Large hard ore lumps are mixed in raw ore, and iron impurities may be mixed in during crushing. Roll skins of conventional crushers wear rapidly and need frequent replacement.
Strict dust control standards are implemented in the plant. Old crushing equipment generates heavy dust and fails to meet environmental protection production requirements.
According to the property of sulfur concentrate sand, Huashengming engineers inspected the production site and designed a matched two-stage crushing set to tackle tough pyrite processing issues:
1.The primary crushing station uses a double toothed roller crusher. Its layered toothed rolls break massive pyrite chunks, with anti-stick tooth design stopping material buildup and frequent blockage halts. The wide feed opening takes 300mm raw ore directly without pre-sieving.
2.A hydraulic double roller fine crusher serves secondary crushing. Its wear-resistant alloy rolls resist abrasion from hard rock and iron debris inside pyrite. Built-in hydraulic overload protection retracts rollers automatically when uncrushable iron enters, avoiding roller breakage and lengthening equipment lifespan.
3.Precise adjustable roller gaps control output granularity and avoid over-crushing. More sulfur ore meets standard size, less sulfur concentrate sand wastes during sorting, and sulfur recovery efficiency gets lifted fundamentally.
4.All units reserve sealed dust removal joints to connect factory dedusting gear, limiting dust escape during crushing and meeting mine environmental norms.

Sulfur Concentrate Sand Crusher on Production Site
Stable Capacity Output: The complete crushing line steadily reaches its designed high capacity, supporting round-the-clock continuous production with obviously higher output than outdated original equipment.
Complete Solution to Material Blockage: The anti-adhesion roller structure always requires only simple routine cleaning per shift, thus greatly shortening time spent on shutdown maintenance.
Higher Recovery Rate of Sulfur Concentrate Sand: Uniform discharge size reduces loss of fine sulfur particles, increasing finished concentrate output and bringing steady economic benefits.
Lower Operation and Maintenance Costs: Wear-resistant roll skins have longer service cycles, hydraulic protection cuts breakdown frequency, reducing investment in wear part replacement and maintenance.
Plant Manager: Material adhesion blockage and excessive fine crushing have long been persistent problems plaguing our concentrator. We tried crushing equipment from multiple brands yet failed to solve these issues thoroughly. After adopting Huashengming two-stage crushing unit for sulfur concentrate sand, the equipment runs stably with production volume and sulfur concentrate yield exceeding our expectations. Our after-sales engineers provide on-site installation, commissioning and regular follow-up services, making the whole cooperation worry-free. We will prioritize Huashengming for future production line expansion projects.
