I knew SBM through a friend. SBM salesman was very enthusiastic and patient when making production scheme for me. After investigating SBM's factories and sample production lines personally, I found that SBM is very professional. I have purchased one jaw crusher, three sets of cone crusher, two sets of vibrating screens from SBM. Now the machines are running well. Besides, SBM has good after-sale service, and they can pay regular return visit. Excellent！ Person in Charge of A South African Mining Corp.
