A projectile impact crushing sand making machine

Abstract

The invention discloses a projection impact type gravel sand making machine. The machine is mainly used for solving the problem that an existing sand making machine is used for crushing in a rotatingor swinging mode, and the load of a motor is large. The machine comprises a sand making box, one side wall of the sand making box is a semicircular shell, a rotating shaft is arranged at the circle center of the semicircular shell, a plurality of projection plates are annularly fixed on the shaft section, located in the sand making box, of the rotating shaft at equal intervals, an impact plate isarranged on the side, far away from the semicircular shell, of an inner cavity of the sand making box, and a metal screen is arranged below the impact plate. According to the machine, the rotating shaft, the projection plate, the impact plate, the metal screen, a first disc, a first connecting rod and a crushing plate are arranged, the projection plate drives gravel to rotate so as to be projectedout from the top of the semicircular shell, the gravel collides with the impact plate to be crushed, meanwhile, the crushing plate is matched with the impact plate to further crush the gravel, then disqualified gravel slides into the bottom of the semicircular shell again through the metal screen, and is subjected to cyclic crushing again, so that crushing is sufficient and uniform.

Description

technical field [0001] The invention relates to a sand making machine, in particular to a projectile and impact crushing stone sand making machine. Background technique [0002] The new sand making machine (vertical shaft impact crusher) is suitable for crushing soft or medium hard and extremely hard ore materials with a hardness not higher than 320Pa. Sand making machines are widely used in large, smelting, building materials, roads, railways, water conservancy and Chemical industry and many other sectors. The hammer head is a sand making machine with integral structure, and the hammer head is directly connected to the rotor through the rod. With this structure, the hammer head will be subjected to a large force during the crushing process, and the hammer head is easy to wear. [0003] The hammer head of the existing sand making machine is easy to wear, and it is crushed by rotating or swinging, so the motor load is relatively large, and the gravity of the sand and stone ...

Problems solved by technology

With this structure, the hammer head will generate greater force during the crushing process, and it is easy to wear the hammer head

[0003] The hammer head of the existing sand making machine is easy to wear, and it is crushed by rotating or swinging, so the motor load is relatively large, and the gravity of the sand and stone itself is not used for crushing operations.
