Sand making machine and sand making method

Abstract

The invention discloses a sand production machine, and belongs to the field of building materials. The sand production machine comprises a crushing device, a screening device and a sand washing device; the screening device is arranged under the crushing device; the sand washing device is arranged beside the screening device; the crushing device consists of a motor, a transmission belt and crushingblades; the screening device consists of a screen net, a vibration motor, a damping spring, a vibration absorbing block and a refining device; and the sand washing device comprises a water inlet pipe, an upper motor, a lower motor and a rotating drum. The content of such impurities as stone powder in machined sand is very lower, so that the effect of the machined sand can be fully exerted, and the negative effect of the impurities on the building use effect is prevented. Water resources used in the sand preparation process can be filtered in the machine to achieve secondary utilization, so that the energy is saved as far as possible, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a sand making machine and a sand making method. Background technique [0002] At present, sand is widely used, and plays an important role in construction, beautification, decoration and other aspects. With the acceleration of the development process, the demand for sand has risen rapidly, and the requirements for sand quality have become more stringent, but the existing natural sand obviously cannot meet the supply, and the state has issued regulations prohibiting unauthorized mining of natural sand (except for cleaning rivers). At this time, the emergence of machine-made sand can make up for this gap. Invention content: [0003] In order to protect the safety of the river course and reduce the amount of river sand mining, this invention aims to propose a sand making machine, which can effectively remove and collect the by-product stone powder, so as to produce h...
