Embodiment Construction

[0030] like Figure 1-10 As shown, a sand sheatting process of a mechanism sand, comprising the steps of:

[0031] Step 1, the raw stone enters the hoist through the pit;

[0032] Step 2, the raw stone passes through the V-shaped sieve, the straight-line vibration screen, and the clean stone separated after the level is adjusted into the impact sander;

[0033] Step 3, there is a multi-particle and powder in the stone after the impact molding machine, and multi-level screening is performed again through the hoist.

[0034] The stone enters the sander body from the feed opening, and the sandy scorpion will fall into the screening board, then fall into the lower oriented channel, then send it down from the leakage hole; after the stone sand is completed, The screening dish is implemented to the screen of the sand. During the screening process, one end of the flip plate will be turned upward, and the flip plate is turned upward, and the automatic dredging of the lower plate is realize...

Abstract

The invention discloses a sand making process for machine-made sand and a sand making device. The sand making process comprises the following steps that 1, raw material stones enter an elevator through a feeding pit; and 2, after the stones pass through a V-shaped screen and a linear vibrating screen and are subjected to grading adjustment, the separated clean stones enter an impact type sand making machine. According to the sand making process, the stones contain a certain amount of fine sand, powder enters the sand making machine after being subjected to multiple screening, the stones entering the impact type sand making machine are clean, the situation that the impact efficiency of the impact type sand making machine is reduced due to much powder due to the fact that the stones contain a certain amount of powder is avoided, due to the fact that a grading adjusting device is arranged, the quantity of coarse particles in the screening process can be randomly extracted on line and controlled, then positive feedback sand making is carried out, and due to the fact that coarse particles are intercepted by the grading adjusting device, the grading plumpness of qualified sand can be adjusted, so that the requirements of high-quality machine-made sand are met.

Description

Technical field [0001] The present invention belongs to the field of sand making techniques, and more particularly to a sand making process and a sand making device for mechanism sand. Background technique [0002] The mechanism sand process is not just the process of large particle stones with large particle size into a less small particle diameter of some construction sand, but through mechanical sand, through the control of the sand production process, make a larger When the particles change into fine particles, a certain level can be formed at a time, which is controlled, so that the gradings of large, medium, small, and powder are formed in the granules to satisfy the concrete, mortar and other construction of the aggregate profile having a certain particle grade. Construction mechanism boutique sand. [0003] During the existing sand-absorbing process, due to multi-particles and powder in the shock, there is a lot of impact efficiency during the sand.
