Vertical milling sand making machine

Abstract

The invention relates to technical field of industrial sand making equipment, and particularly provides a vertical milling sand making machine characterized in that a transmission apparatus includes amotor, a coupling and a speed reducer. The output shaft of the motor is connected with a horizontal input shaft hole in the speed reducer through the coupling. A rotary disc is coupled to a verticaloutput shaft of the speed reducer. A milling apparatus includes a mill roller, a rotary arm and a mill disc. The mill disc of the milling apparatus is fixed by the rotary disc. A pressurizing device is fixed to ground, wherein the working end of the device is rotatably connected to the mill roller in the milling apparatus. A position limiting device is arranged on periphery of the transmission apparatus, wherein an inclined arm of the position limiting device is in bolt connection with the rotary arm of the milling apparatus. Compared with the prior art, the sand making machine is high in milling efficiency, is low in electricity consumption, is high in sand yield, is large in granularity of feeding raw materials, can form round and smooth sand grains, is simple in process and small in occupied area, is low in noise and dust raising, is easy to use and maintain, is low in operation cost and is low in consumption of wear-resisting materials.

Description

technical field [0001] The invention relates to the technical field of industrial sand making equipment, in particular to a vertical mill sand making machine. Background technique [0002] At present, the most popular machine-made sand production equipment in China mainly adopts Metso VS1 series vertical impact crusher technology. When thrown out from the launch port, it first collides with a part of the free-falling material after rebounding, and then impacts the vortex-shaped material lining or the impact block in the surrounding vortex chamber together, and is first rebounded to the top of the crushing chamber, and then moves downward It collides with the material launched from the impeller channel to form a continuous material curtain, and finally it is discharged through the lower discharge port. However, the vertical impact crusher has many shortcomings that cannot be improved, such as high energy consumption per unit of finished sand, low sand production rate, short ...
