The cylinder diameter of the 1557 ball mill is 1.5 meters, and the cylinder length is 5.7 meters. According to the different ore discharge methods, the 1557 ball mill can be divided into grid type and overflow type. The grid type ball mill is equipped with an ore discharge grid at the ore discharge end, which is mandatory. Discharging ore can effectively avoid over-grinding, and the overflow ball mill is more suitable for second-stage grinding or grinding that requires higher fineness, and can grind minerals into finer particles. According to different grinding methods, ball mills can be divided into dry ball mills and wet ball mills. Dry ball mills are mainly used to grind powder and do not need to add water. They are used with a wind classification system; wet ball mills need to add water and are used with a hydraulic classification system. , the wet ball mill has a wider application range and can be used to grind various metallic ores and non-metallic ores. Here the editor will give a brief introduction to the technical parameters, weight, output per hour and maintenance methods of the 1557 ball mill.

The 1557 ball mill can be used for dry grinding or wet grinding. When used for wet grinding, the output will be larger than that of dry grinding. Because of the scouring effect of water flow, the discharging speed is increased. The machine is equipped with a forced feeder to ensure that all the sand fed into the ball mill by the feeder can enter the ball mill. While ensuring the feeding, we must also ensure the discharging speed, otherwise the inside of the ball mill will easily swell. Therefore, we have optimized the grate plate at the discharging end of the ball mill according to customer needs, which is more conducive to discharging.

Dry 1557 ball mill: uniform discharge, low failure rate, no grinding, swelling, etc., no need to add water, saving costs, but sometimes dead corners will be formed during the grinding process, and the materials entering the dead corners are very small. Hard to grind.

Wet 1557 ball mill: Wet grinding is suitable for most materials, including all kinds of metal ores and non-metallic minerals. As long as the materials will not react when exposed to water, thereby affecting the quality of the finished product, wet grinding can be used. Common ones include copper ore, iron ore, molybdenum ore, phosphate ore, feldspar ore, fluorite ore, etc. During wet grinding, the ratio of steel balls, materials, and water is 4:2:1. The specific ratio needs to be determined through grinding tests.
