Rod milling sand making machine

Abstract

The invention discloses a rod milling sand making machine, and belongs to the technical field of sand making equipment. The problem that the sand making efficiency is reduced due to the fact that a screen in an existing device is prone to being blocked is solved. The rod milling sand making machine is technically characterized in that the rod milling sand making machine includes a shell, an innercavity, a coarse sand crushing cavity, a fine sand crushing cavity, a coarse sand screening cavity and a fine sand screening cavity, the inner cavity is formed in the shell, the inner cavity is internally and obliquely provided with a screen, the inner cavity is divided into the coarse sand screening chamber and the fine sand screening chamber by the screen, the lower part of coarse sand screeningcavity communicates with the coarse sand crushing cavity, the lower part of the fine sand screening cavity communicates with the fine sand crushing cavity, and a feeding mechanism is arranged on theright side wall of the shell. According to the rod milling sand making machine, sand can be crushed after being screened, the sand making efficiency is improved, and at the same time, the phenomenon of incomplete sand crushing caused by uneven sand particle size is avoided.

Description

technical field [0001] The invention relates to the technical field of sand making equipment, in particular to a rod mill sand making machine. Background technique [0002] The sand making machine is suitable for crushing and shaping of soft or medium-hard and extremely hard materials. It is widely used in various ores, cement, refractory materials, aluminum where the clay clinker, corundum, glass raw materials, machine-made building stones and gold slag, especially for Silicon carbide, corundum, sintered bauxite, American sand and other high-hard, extra-hard and wear-resistant materials have higher output efficiency than other types of crushers. [0003] Chinese patent CN204564532U discloses a new type of high-purity quartz sand sand making machine, which includes a hopper and a sand making machine. The hopper and the sand making machine are connected to each other. There are fasteners between the sand machines, the fasteners are clamps, there is a screen in the hopper, th...

Problems solved by technology

[0004] The object of the present invention is to provide a rod mill sand making machine, which includes a shell, an inner cavity, a coarse sand crushing chamber, a fine sand crushing chamber, a coarse sand screening chamber and a fine sand screening chamber. The inner cavity is provided with a screen obliquely, and the screen divides the inner cavity into a coarse sand screening cavity and a fine sand screening cavity. The lower part of the coarse sand screening cavity is connected with a coarse sand crushing cavity, and the lower part of the fine sand screening cavity is connected There is a fine sand crushing chamber, and the right side wall of the housing is provided with a feeding mechanism to solve the problem that the screen in the existing device is easily blocked, resulting in a decrease in sand making efficiency
