Ball is the material being broken, and then smash the key equipment. It is widely used in cement, silicate products, new building materials, chemical fertilizer, non-ferrous metal processing, such as glass ceramics industry production of all kinds of ores and other materials for grinding of dry or wet grinding, the copper ball played an important role.
Steel ball diameter is very small. When the ball filled with a certain amount of time, small diameter is more, the ball drops down many times, the grinding area is large, but each ball strike force; large diameter is few, the ball drops hit a few times. The grinding area is small, but each ball strike force. So, need reasonable ball mill to coarse grinding ball for a big ball. With thickness ranging from various particle materials, with the ball, the ball should be the quality ratio of a particle material quantity suitable for its ground in equal proportions.
Steel ball diameter (D) size can be roughly by ore particle diameter (d): D=25.4 (d) 0.5 as the cylinder is in accordance with the provisions of the speed around the horizontal axis, the cylinder body and ore grinding medium in the centrifugal force and friction force under the action of the cylinder liner to be a the height, and then from the cylinder wall free fall or drop, the ore is under the impact and the grinding effect and crushing of ore from the hollow shaft neck. One end of the cylinder body continuously into the cylinder, and after grinding products through the hollow shaft neck at the other end of the continuously discharged ore cylinder displacement is the use of continuous pressure into the ore to achieve.When wet grinding, the ore is carried away by the current
A series of methods to teach you how to increase the yield of ball mills
Generally speaking, there are 3 direct ways to increase the output of ball mill:
Adding fine crusher before grinding machine;
Improving grinding system and improving grinding efficiency;
The high efficiency separator. As we all know, grinding finely grinding powder selection is the premise, is to ensure that, in mill reconstruction is fundamental.
Grinding finely made feeding size is greatly reduced, thereby reducing the load of the grinding system; powder selecting efficiency, the most direct benefit is to maximize the finished powder was promptly selected, reduce the finished cement powder return rate, reduce the mill load; and mill reconstruction, also is to improve the grinding system is. The most fundamental solution. The feeding size reduced, powder selecting efficiency, if grinding efficiency is low, the effect is not only the production of ball mill, it affects the quality of products.
Hunan Fengwei Wear Parts Foundry products selected high-quality raw materials, through the reasonable ratio of element (molybdenum, manganese, lanthanum etc.), forming a medium frequency melting furnace, heat treatment after a series of process (after heat treatment temperature reaches 1045 degrees) produced products of toughness and wear resistance can reach 1.2 to 1.5 times that of similar products. Users throughout the country more than 20 provinces, city, autonomous region and have their own foreign trade team, products exported to all over the world, won the domestic and foreign users alike. Welcome new and old customers to map customized calls.
