I knew SBM through a friend. SBM salesman was very enthusiastic, and made the production plan patiently, then invited me to visit SBM production bases and sample plates. After investigating personally, I found that SBM is very professional. I have purchased one jaw crusher, three sets of cone crusher, two sets of vibrating screen 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.
