Jiangxi 800 tons per hour granite sand production line case
Granite is a high-hardness raw material (Mohs hardness 6-7), which has extremely high requirements for crushing equipment. ZOOMJO GROUP engineers innovatively adopted the "three-stage crushing + two-stage shaping" process to ensure the excellent quality of 0-5mm fine machine-made sand in view of the characteristics of raw materials ≤1000mm:
Customer Background
Ganzhou, Jiangxi, as an important building materials production base in East China, has rich reserves of granite resources. In 2022, local entrepreneur Mr. Chen invested in the construction of a granite sand production line with an output of 800 tons per hour. The full set of equipment was provided by Henan ZOOMJO GROUP Machinery with professional solutions. After a year and a half of stable operation, the production line has become a benchmark supplier of high-standard machine-made sand in southern Jiangxi, and its products are widely used in high-end fields such as high-speed rail and commercial concrete mixing stations.
Project Overview
Granite is a high-hardness raw material (Mohs hardness 6-7), which has extremely high requirements for crushing equipment. ZOOMJO GROUP engineers innovatively adopted the "three-stage crushing + two-stage shaping" process to ensure the excellent quality of 0-5mm fine machine-made sand in view of the characteristics of raw materials ≤1000mm:
Process
Coarse crushing stage
The raw materials are evenly fed into the PE1200×1500 jaw crusher through the ZSW600×1600 heavy-duty vibrating feeder and crushed to 250-300mm.
Secondary crushing stage
Secondary crushing is carried out by HPG400 hydraulic cone crusher, and the particle size of the output is controlled at 30-50mm.
Fine crushing and shaping
Two sand making machines are used for vertical shaft impact crushing to achieve "stone hitting stone" + "stone hitting iron" dual-mode sand making.
Screening, washing and grading
3YK3080 high-frequency screen: three-level precise screening
XS3620 bucket sand washer: adjustable powder content (3-10%)

Customer Testimonials
"ZOOMJO GROUP's production line completely overturned our understanding of granite sand making. Not only did the output exceed expectations, but most importantly, the finished sand could be sold for 8-10 yuan more per ton at the local commercial mixing station. After the equipment was put into operation for 18 months, the lining of the cone crusher was replaced for the first time, which truly achieved high production and low consumption!" - Mr. Chen, Ganzhou Building Materials
ZOOMJO GROUP provide:
✔ Free raw material testing ✔ 3D design of production lines ✔ Operator training ✔ 24-hour technical support throughout the year ✔ Spare parts supply guarantee
