Double-flow-channel central feeding type rotor cavity

Abstract

The invention relates to the technical field of mining machinery crushing, and discloses a double-flow-channel central feeding type rotor cavity. The cavity comprises an impeller frame, wherein two material distributing plates are clamped to the front face of the impeller frame through hinge pins, first hammer heads and a second hammer head are installed on the front face of the impeller frame, atool bit is bolted to the position, between the two first hammer heads, of the front face of the impeller frame, a material distribution cone is clamped inside the impeller frame through a groove, anda rotor flange connecting assembly is installed on the front face of the impeller frame through a groove. According to the cavity, materials slide through the tool bit in a rotating process and are thrown to an anvil inside a main machine barrel, the materials flying at a high speed collide with the anvil for the first time, rebound and then collide with the first hammer heads and the second hammer head for the second time, the materials can be fully crushed, a sand forming rate of the materials can be increased, a passing quantity is large, the cost of a sand making production line is reduced, and the practicability of equipment is improved.

Description

technical field [0001] The invention relates to the technical field of mining machinery crushing, in particular to a double-channel center-feeding rotor chamber. Background technique [0002] The consumption of sand and gravel aggregates in my country is increasing year by year. In the past, natural sand and gravel were the main sources, mainly from mountains and rivers. With the depletion of natural sand and gravel resources, the improvement of ecological protection requirements and the continuous increase in the demand for construction projects, machine-made sand and gravel are gradually replaced. Natural sand and gravel make up for market demand. At present, machine-made sand and gravel have accounted for about 70% of construction sand and gravel. Sand making equipment in the mining machinery industry has generally suffered from low sand production rate and small output. The production line generally requires multiple sand making machines to be connected in parallel. Cont...
