Only directfired rotary kilns employ refractory in an indirectkiln heat transfer occurs primarily through the kiln shell wall Refractory would be another barrier for heat to pass through before it is in contact with material reducing the efficiency of the process
Great energy conservation, wide adjustment range, low noise and little dust
1.5 times or even 2 times larger crushing cavity than that of other crushers, large feeding mouth
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.
