Split Tensile Strength Of M20 Concrete
Split tensile strength is an indirect method to determine the tensile strength of concrete The M20 grade concrete is prepared and placed in the mould cylinder of size 150mm x 300mm
Great energy conservation, wide adjustment range, low noise and little dust
Good appearance, excellent sealing, no dust pollution or leakage,few easy-wearing parts
1.5 times or even 2 times larger crushing cavity than that of other crushers, large feeding mouth
Stable performance, little noise pollution , low acicular content, no crackings inside, little wear and long service life
With features of reliable structure, high working efficiency and easy adjustment
VSI sand maker, also called VSI crusher, is the major machine for sand making plant.
Ball mill is the key machine to grind the crushed materials. Ball mill machine is widely used to process cement, silicate product, building material, refractory material, fertilizer, ceramics and glass, etc.
On the basis of domestic mills, fote raymond mill is produced. The raymond roller mill enjoys the features of high working efficiency, low energy consumption, small floor space and small cost.
As a famous Chinese sand dryer supplier and manufacturer, our company has manufactured a lot of advanced sand dryers with quite a reasonable drying machine price in the dryer market.
