Henglong Machinery, founded in 2003 in Shuitou, explains why its HLMJD two-stage polishing line solves the two most common headaches of stone factories: uneven slab gloss and high utility bills. Many workshops struggle with inconsistent shine, poor edge finish and fast abrasive wear, especially when a single row of fixed-pressure heads cannot follow slab shape. The HLMJD splits rough grinding and fine polishing into two staged zones. A PLC touch-screen identifies each slab shape automatically and every head lifts independently, keeping pressure even across edges and corners, while an abrasive-wear alarm extends disc life. Available in 12 to 20 heads, the machine works on 600 to 2100 mm wide slabs at up to 60 to 80 square meters per hour, holding a uniform 85 to 95 gloss units on marble and granite. The 16-head model uses about 25 cubic meters of water per hour, roughly 15 percent less than a conventional line, and optimized power saves about 12 percent of electricity per square meter. CE, ISO 9001 and ISO 14001 certified and exported to over 20 countries, Henglong customizes voltage, width and power to local grids.

Henglong Machinery, a professional stone machinery manufacturer in China, explains how to design a balanced stone processing line by matching the capacity of cutting, calibrating and polishing stages. A line is only as fast as its slowest stage: if cutting can produce 800 square meters per day but the calibrating machine can only process 500, the factory idles daily and part of the investment is wasted. The guide shows how to calculate the capacity of each stage and how to design backward from your target daily output, so every machine matches the others and the bottleneck is removed. It covers the role of each stage, capacity comparison and selection logic, including how to choose a calibrating machine, a marble machine cutter and a polishing machine as one matched set. A balanced line brings higher utilization, lower labour cost and shorter delivery time. Even when the Stone polishing machine price is higher for a larger model, the extra capacity usually costs less than idle time caused by a weak stage. Henglong supplies the complete range from cutting and calibrating to polishing, including cutting and polishing stone machine lines, and provides full-line engineering support as a professional china stone polishing machine manufacturer.
