An energy-saving and environment-friendly rolling sand making machine

Abstract

The invention belongs to the field of rolling equipment and particularly relates to an energy-saving and environment-friendly rolling sand making machine. The energy-saving and environment-friendly rolling sand making machine comprises a rack, a cylinder and a driving device; a lining plate and rolling media are arranged in the cylinder; each of two ends of the cylinder is provided with feeding buckets; sand discharging holes are formed in the middle of the cylinder; and a screen is arranged outside the cylinder, is arranged along the circumference of the cylinder, is opened at two ends and is connected with the cylinder through connecting columns. Materials are fed from two ends of the rolling sand making machine and are discharged from the middle of the rolling sand making machine, so that the processing efficiency is greatly increased; in addition, the materials are more smoothly discharged, so that the blocking phenomenon is not easily caused, the condition that qualified materials operate in the cylinder for a long term can be avoided, the energy consumption of equipment is reduced, and the production continuity is improved; meanwhile, the screen is mounted outside the cylinder, and rolling and screening are simultaneously performed, so that the equipment investment is reduced; and the rolled materials are screened in a classifying way, and the materials with relatively large particles return to a feeding chute, so that self-closed cycle is realized, and the automation capacity of the equipment is improved.

Description

technical field [0001] The invention belongs to the field of rolling equipment, and specifically provides an energy-saving and environment-friendly rolling sand making machine. Background technique [0002] Sand is an indispensable building material in construction engineering. With the rapid development of the construction industry, the supply of traditional natural river sand has exceeded demand, and artificial sand has gradually entered the market. At present, most of the drum-type sand-making equipment adopts ball mill and rod mill, that is, steel rods, steel balls and other grinding media are added to the rotating cylinder, and the grinding medium is brought to a certain height with the rotation of the cylinder and then automatically Throw it up and down to break the ore. However, most of these devices feed from one end of the cylinder and discharge from the other end of the cylinder, that is, feed from one side, the processing efficiency is low, and the discharge is ...

AI Technical Summary

Problems solved by technology

However, most of these devices feed from one end of the cylinder and discharge from the other end of the cylinder, that is, feed from one side, the processing efficiency is low, and the discharge is not smooth, and it is prone to clogging.

The size of the ground material is uneven. If it needs to be subdivided, it still needs to be screened by screening equipment, which consumes a lot of energy.
