High-efficiency screening type large-scale double-toothed roller crusher with self-contained material distribution device

Abstract

The invention discloses a large efficient screening-type double-toothed roll crusher provided with a distribution device. The double-toothed roll crusher comprises a crushing device and the distribution device. The crushing device comprises a crushing drive motor, a fluid coupling, a reducer, a double-drum gear coupling, a crushing box, a base support, a left toothed roll, a right toothed roll and a lubricating grease pump, wherein the crushing drive motor, the fluid coupling, the reducer and the double-drum gear coupling form two sets of crushing drive units; and the two sets of crushing drive units are connected wit the left toothed roll and the right toothed roll inside the crushing box respectively. The distribution device comprises a distribution chute, an adjustable distribution stick, a movable connecting bracket, a distribution seat and a fixed connecting bracket, wherein the fixed connecting bracket and the distribution seat are fixed on the crushing box of the crushing device, the distribution chute is fixed at a discharge port of a material output belt machine head, and the distribution chute is connected with the crushing box through the movable and fixed connecting brackets. According to the large efficient screening-type double-toothed roll crusher, the problems of capital investment, equipment movement and the like of crushing equipment combined by a plurality of devices are solved fundamentally, the labor intensity of daily equipment maintenance is reduced, and the mining of surface mine materials is accelerated.

Description

Technical field: [0001] The invention relates to a crushing device, in particular to a high-efficiency screening type large-scale double-toothed roller crusher with a self-contained material distribution device, which is suitable for open-pit coal mines, open-pit mines and crushing stations installed outdoors, with an output of 2000-4000 tons , the input material is less than 300mm, the output material is 50-150mm, and the material hardness is less than or equal to 200Mpa combined crushing equipment. Background technique: [0002] At present, for open-pit coal mines above 2,000 tons and existing crushing stations in open-pit mines, after primary crushing, the materials are transported to secondary crushers by belt conveyors for crushing. There are usually two or two secondary crushing equipment. The above crushing equipment participates in crushing, and the corresponding screening equipment needs to be equipped below. Because the conveying equipment (universal belt conveyor...

AI Technical Summary

Problems solved by technology

Not only is the equipment investment cost high, but it also leads to disadvantages such as long installation and commissioning period, poor site applicability and equipment mobility, which to a large extent restricts the rapid development of open-pit mine material mining
