Sand making process for machine-made sand and sand making device
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.
本发明公开了一种机制砂的制砂工艺及制砂装置，包括以下步骤：步骤一、原料石子通过投料坑进入提升机；步骤二、石子经过V型筛、直线震动筛、级配调后分离出的干净石子进入冲击式制砂机。本发明石子中含有一定量的细砂、粉先经过多道筛分后进入制砂机，进入冲击式制砂机石子是较干净的，不会因为石子中含有一定的粉量而造成冲击制砂机因粉多而降低冲击效率，中间因为了有级配调节装置，可以在线随机抽取、控制筛分过程中的粗颗粒的量再正反馈制砂，由于有级配可调装置拦截偏粗颗粒，可调整合格砂的级配的饱满度，以符合精品机制砂的需求。
