Vertical shaft impact sand making machineIt is a kind of sand making equipment upgraded on the basis of retaining the advantages of the original sand making machine. It has become the mainstream equipment in the machine-made sand field. It is widely used in sand making of pebbles, river pebbles, granite, bluestone, limestone, basalt, tailings and waste materials, and has accumulated a good market reputation.
Compared with the traditional sand making machine, what are the advantages of the new vertical shaft impact sand making machine?
1. Improved the four-port impeller. The impeller structure of impact crushing sand making machine is a new four-port deep cavity design. Compared with the traditional three-port impeller, the processing capacity and crushing efficiency are increased by about 10-20 tons, and the output is relatively large.
2. Compared with traditional manual lubrication, fully automatic thin oil lubrication has the advantages of long oil change interval and uniform lubrication. Equipped with PLC and intelligent instruments, the lubrication temperature is controllable, and is equipped with a cold air system to avoid excessive bearing temperature and increase the service life of transmission components such as bearings.
3. Optimize the type of crushing cavity. Impact crushing has two crushing methods: "stone to iron" and "stone to stone". In the "stone-to-iron" aspect, the installation angle of the impact block is optimized, energy loss is reduced, and stable production is maintained; in the "stone-breaking" aspect, the material layer separator is added to form a dense and stable stone layer, and further The crushing efficiency is improved. Through the overflow device, the gradation of the finished product is also changed. The sand is more reasonable, and the particle shape is better, which is equivalent to river sand.
4. Wear-resistant parts are more durable. Through the optimization of the impeller structure and technology, the protection of the impeller body of the sand making machine and the fixing of the wear parts are more durable. Under the same operating conditions, the service life of the impeller and wear-resistant parts is more longer than that of the traditional sand making machine, and the equipment runs more durable and stable, and the cost is lower.
5. It is easy to maintain. The traditional impact crusher has no lifting device. The Vsi6x series is equipped with a professional lifting device, which is convenient for machine installation and maintenance, has low labor consumption, short downtime, and does not affect later production.
6. The finished sand is of higher quality. The machine-made sand produced by the traditional vertical shaft impact sand making machine has sharp edges and corners, relatively large particles, large ends of the gradation, small middle, and a fineness modulus of generally above 3.1 or even higher. The fine sand produced by the vsi6x sand machine is smooth, and its gradation conforms to the sand standard of Zone II. The fineness modulus is adjustable and controllable below 3.0, and the fine sand ratio of 0.15 to 0.6 mm can be increased to meet the requirements of higher standard finished sand.
