Description

Rotary disc type conical sand making machine

Technical Field

The utility model relates to a mining machinery equipment technical field especially relates to a rotary disk circular cone system sand machine.

Background

Because the exploitation of natural river sand is limited by environmental protection, artificial sand becomes a hot door, and the rotary disk type sand making machine is specially used for producing equipment provided by fine material grade materials. The rotary disc type cone sand making machine is different from a common cone crusher which adopts a single-layer crushing mode that a crushing execution part directly extrudes materials. The rotary disc type cone sand making machine adopts a 'lamination crushing' principle, namely, the 'lamination crushing' is a comprehensive effect of converting the extrusion and impact of a crushing execution part of a crusher on materials into mutual impact and grinding among multiple layers of material particles, so that the materials are crushed. The main structure of the rotary disc type conical sand making machine is composed of a frame body part, a supporting sleeve part, an adjusting sleeve part, a movable cone part, an eccentric sleeve part, a bowl-shaped tile frame part, a transmission shaft part and the like, wherein a transmission shaft part is driven by a main motor, and the movable cone part is driven by a transmission belt of a large gear and a small gear to perform eccentric motion in a cavity, so that the principle of material crushing is realized.

Before the advent of the rotary disk type conical sand making machine, the industry generally used a reverse impact crusher, a ball mill, a pair of roll crushers to produce artificial sand, and compared with the rotary disk type conical sand making machine, these devices had the following disadvantages: the ball mill can produce fine-grained products, but has high power consumption, large abrasion of steel balls, relatively high production cost and low yield; when the impact crusher crushes abrasive materials, parts such as the striking plate, the impact plate and the like are quickly worn, the operation rate of the machine is low, the production cost is high, and on the other hand, the impact crusher also generates excessive superfine products; as the principle of the roller crusher is that two rollers crush, most of finished products are flat, and the requirements of customers cannot be met frequently. The rotary disc type cone sand making machine does not have the problems, but the existing rotary disc type cone sand making machine also has the following defects, firstly, most of the existing industry only carries out modification to the cone crushing to a certain degree, so that the rolling mortar wall and the crushing wall are closer, the crushing cavity becomes narrower, and the materials can be crushed to the granularity of the sand. The lower surface of a rolling mortar wall of the cone machine is basically in an arc-shaped structure, a crushing cavity is gradually narrowed from bottom to crush materials, the crushing cavity is only narrowed after the rolling mortar wall is close to the crushing wall, and the shape of the crushing cavity is not changed, so that the fineness of sand can be controlled only by a small section of area close to an ore discharge port of the crushing cavity, and the small section of area cannot meet the requirement of the fineness of produced sand; secondly, the structure of the crushing wall is not changed, the crushing wall is a whole large block, but in the sand making process, the area with the main crushing function is at the lower section (or outer section), the upper section is only used for assisting crushing, so that the lower section is worn more quickly than the upper section, after the lower section is worn to a certain degree, the whole crushing wall needs to be completely replaced, and the crushing wall needs to be made of high-strength materials, so that more cost is increased; secondly, the rolling mortar wall is fixed by a U-shaped screw in the prior art, and a hook part on the rolling mortar wall is aligned with the U-shaped screw and is put down, so that the installation and the disassembly are troublesome, the requirement on accurate alignment is met, otherwise, the installation is not good, and the installation consumes long time; thirdly, the bearing capacity of the U-shaped screw and the hook part is not high enough, and the U-shaped screw and the hook part may fail after long-term use; fourthly, the materials are directly input into the hopper, so that the phenomena of uneven stacking, more and less materials are easily caused, and the efficiency of crushing and sand making is influenced.
