How About The Finished Product Rate Of Roll Sand Making Machine？The finished product rate of the roller sand making machine is affected by many factors, but the overall performance is high, as follows:
1. Basic yield range
Under normal circumstances: the yield of a roll sand making machine is usually between 80% and 100%. For example, when processing river pebbles, the yield is about 80%, while some optimised equipment (e.g. equipped with shaping device) can reach 95% or even close to 100%.
Compare with other equipment: Compared with vertical shaft impact crusher (60%-85% yield) and double-shaft hammer crusher (100% yield), roll sand maker achieves a better balance between yield and product quality.
2. Key factors affecting the yield
Characteristics of raw materials:
The hardness, humidity and particle size of raw materials directly affect the yield. For example, high hardness river pebbles may have a slightly lower yield (about 80%), while softer materials such as common limestone have a higher yield.
Equipment performance:
High quality roll sand making machine can reduce wear and stabilise the yield by optimising the roll skin material (e.g. high chrome and high manganese alloy) and hydraulic adjustment system.
Equipped with shaping devices (e.g. patented high speed shaper), the yield can be increased up to 100%, while improving the sand shape and crushing value indicators.
Operational level: Skilled operators can optimise yield by adjusting parameters such as roll gap and pressure.
3. Practical application cases
Model 1210 Hydraulic Roller Sand Making Machine: In the task of pebble sand making, the rate of sand formation reaches 95%, and the particles are even and less powdery.
Technological transformation project: after a cement company adopted the roller sand making process, the yield of mechanism sand is close to 100%, and the comprehensive cost is as low as RMB 10.74/tonne, which meets the standard of construction sand.
