High-strength crusher for sand making

Abstract

The invention discloses a high-strength crusher for sand making, relates to the technical field of crushing devices in a sand making process, and aims to solve the problems that due to different production requirements and different particle size requirements of each batch of discharged sand, the particle size filtering requirement needs to be met by replacing different filter screens, and the working efficiency is reduced by replacing the filter screens. A lower shell is arranged below the upper shell, a crushing cavity is formed in the upper shell and the lower shell, a filtering mechanism is arranged in the crushing cavity, a first filtering net and a second filtering net are arranged in the filtering mechanism, and filtering grooves are formed in the first filtering net and the second filtering net correspondingly. The second filter screen is slidably connected with the filter mechanism through a filter screen sliding groove, a vibration motor is fixedly arranged on one side of the lower shell, damping mechanisms are arranged at the lower ends of the two sides of the lower shell, a feeding filter pipe is fixedly arranged above one side of the upper shell, and a humidifying and drying mechanism is arranged above the feeding filter pipe.

Description

technical field [0001] The invention relates to the technical field of crushing devices in the sand making process, in particular to a high-strength crusher for sand making. Background technique [0002] Crushing operations are often divided into coarse crushing, medium crushing and fine crushing according to the size of the feeding and discharging particles. When crushing, 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. Sand washing machine is widely used in various industries such as construction sites, sand and gravel factories, concrete dam construction sites of hydropower stations, etc. It has high cleaning degree and reasonable structure, large processing capacity and low power consumption, and less sand loss during sand washing. [0003] At present, most of the sand making crushers on the market filter the sand through the filter screen under the ro...

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-strength crusher for sand making, to solve the problem mentioned in the above-mentioned background technology that due to different production requirements, the grain size requirements of each batch of sand are different, and it is necessary to replace different filter screens at this time. To achieve the filtration requirements of particle size, replacing the filter screen reduces the problem of work efficiency
