Embodiment Construction

[0030] A sand making process of machine-made sand, characterized in that: comprising the following steps:

[0031] Step 1. The raw material stones enter the elevator through the feeding pit;

[0032] Step 2: The clean stones separated from the raw material stones through V-shaped sieve, linear vibrating sieve, and grading enter the impact sand making machine;

[0033] Step 3: There are many particles and powder in the stones impacted by the impact sand making machine, and they are screened again in multiple stages by the hoist.

[0034] Stones enter the body of the sand making machine from the feed port, and the finished sand will fall onto the screening plate, then fall into the feeding channel, and then be sent out from the sand leakage hole; after the sand making through the stones is completed, The screening plate realizes the screening of sand. During the screening process, one end of the turning plate will be turned upwards, and the turning plate will be turned upwards ...

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 graded, the separated clean stones enter an impact type sand making machine. The pebbles contain a certain amount of fine sand, powder enters the sand making machine after being subjected to multiple screening, the pebbles 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 pebbles contain a certain amount of powder is avoided, and due to the fact that a grading adjusting device is arranged in the process, the quantity of coarse particles in the screening process can be randomly extracted on line and controlled, then positive feedback is performed for sand making, and due to the fact that coarse particles are intercepted by the grading adjustable 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 invention belongs to the technical field of sand making, and in particular relates to a sand making process and a sand making device for machine-made sand. Background technique [0002] The machine-made sand process is not just a process of turning large-sized stones into smaller particle sizes of certain construction sands through mechanical force, but through the mechanical sand-making process, through the control of the sand-making process, the larger When the particles change into fine particles, a certain gradation can be formed and controlled at one time, so that the particles will form a step gradation of large, medium, small and powder, so as to meet the needs of concrete, mortar and other building aggregate profiles with a certain particle size. Mechanism-made high-quality sand for construction. [0003] In the existing sand making process, the stones contain a certain amount of fine sand, and the stones entering the impact sand making ma...
