Ball mill is a kind of traditional grinding mill and Raymond roller mill is newly developed. Therefore, the latter one is much more advanced than the former one in technology and performance. Here is a simple comparison:1. The grinder mill has few spare parts and the replacement and maintenance are very convenient, so the downtime of roller mill is much shorter than ball mill. And we adopt high quality scaleboard which has long service life so the repair cycle is quite long. And for the replacement of grinding roller on the roller mill, the user can take special measures to reduce the downtime as long as possible. For instance, if there are three or four rollers that have to be replaced, the user can replace one of them and the others can continue to operate.2. The largest allowable granularity of materials into the roller mill can reach to 100-150mm and it has little influence on the productivity. So the users have no need the second stage crushing equipments.3. Cement produced by roller Raymond grinder mill has even granularity. We can find that the sample after being ground for 5 minutes has almost the same granularity with the final product.4. The Raymond mill can operate stably and it has small vibration and low noise which conform to the national requirements on such machine completely.5. The Raymond grinding mill has smaller abrasion value than ball grinding mill. The abrasion value of roller mill is 13.6g/t for producing one tone of cement.6. Owe to the small size and simple system of Raymond roller mill, it needs much less steels than ball mill.China Raymond mill is designed by adopting advanced structure of similar products at home and abroad and bettering them in the industry. The Raymond grinder mill of Henan Hongxing Mining Machinery Co., Ltd. has higher grinding efficiency and lower energy consumption, smaller floor area and investment than that of the ball mill.
