What is the cause of severe wear of the crushing chamber when the sand making machine is used?
sand making machine
has been used for a long time, and the crushing chamber will wear unexplained wear during use. What is the cause of this? Here, our SBM sand making machine engineers will come to analyze you one by one.
First, the number of broken materials entering the parallel area of the sand making machine during the start of the sand making machine (sanding machine) was the highest, and it dropped sharply thereafter. Therefore, the parallel zone is subjected to intense wear and the parallel zone is gradually changed after several days of operation of the sand making machine.
Then, as the lining wears and the contour of the crushing chamber changes, the material that is broken along the height of the crushing chamber is evenly distributed. There is a change in the size of the crushing cavity in the limit wear range of the lining plate, especially the late parallel region does not exist, and the entire cavity shape completely loses the original contour. At this time, the size of the feed port is reduced by about 1.4-1.7 times, and the amount of material processed at the feed port is the largest. As the quality of the product deteriorates due to the absence of parallel zones, the output of the sand making machine equipment also decreases.
In summary, due to the uneven wear of the lining of the sand making machine, the crushing cavity loses the shape of the original crushing cavity, resulting in low life of the lining and a decrease in technical and economic indicators of the
sand making machine
. Therefore, the old-fashioned sand making machine crushing chamber should be improved. The new VSI sand making machine produced by our SBM Mining Equipment Co., Ltd. combines the advanced features of the impact sand making machine to draw on the advanced principle of the world sand making machine. The sand making machine adopts a variety of feeding modes, and utilizes two breaking principles of "stone rock" + "stone hitting iron". It can easily realize the flexible conversion of a variety of broken fine stone shaping functions. Compared with the traditional sand making machine, the sand making machine has low consumption of consumable parts and reasonable cavity design, reducing direct contact between materials and wearing parts. , to reduce the wear and tear of the wearing parts.
