Description

A new type of building material sand making machine

technical field

The utility model relates to a new type of building material manufacturing mechanical equipment, in particular to a sand making machine.

Background technique

The construction of expressways is inseparable from the supply of a large amount of high-quality sand and gravel, and the supply of natural sand and gravel has long been in short supply. The crushed stone materials used in road engineering mainly include crushed stone and sand. , sand is the main raw material of cement mortar, cement brown concrete, asphalt concrete and asphalt sand. The source of sand is natural sand (mountain sand, river sand, sea sand) and artificial sand (machine-made sand). High quality, less restricted by natural conditions, has been more and more widely used.

The material enters the sand making machine from the feeding hopper, and is divided into two parts by the feeder, and one part enters the high-speed rotating impeller from the middle of the feeder, and is rapidly accelerated in the impeller, and its acceleration can reach hundreds of times the acceleration of gravity. Then it is thrown out from the three evenly distributed runners of the impeller at a speed of 60-70 m/s. First, it is impacted and crushed with a part of the material that is self-collected and dropped around the distributor, and then impacted together on the material lining in the vortex support cavity. , is rebounded by the material liner, impacts obliquely upwards to the top of the vortex chamber, and then changes its direction of motion, deflecting to move downwards, and the materials emitted from the impeller flow channel form a continuous material curtain, so that a piece of material is crushed in the vortex crushing chamber The interior is subjected to two or more times of impact, friction and grinding, and the crushed materials are discharged from the lower discharge port. During the whole crushing process, the materials collide and crush each other by themselves, without direct contact with metal components, but with metal components. The material lining is crushed by impact and friction, which reduces corner pollution and prolongs the mechanical wear time. The ingenious self-circulation of airflow inside the vortex chamber eliminates dust pollution.

The material falls into the hopper, enters the high-speed rotating rotor through the central feeding hole, is fully accelerated and thrown out through the launch port, and first collides with a part of the freely falling material after rebounding.

The sand making machines currently on the market are not efficient and cannot meet the production requirements.
