Integrated basalt utilization system and process

Abstract

The invention discloses an integrated basalt utilization system and process. The integrated basalt utilization system comprises a primary bin, a rod vibrating feeder and a soil removal screen, whereinthe rod vibrating feeder is installed on the lower side of the primary bin, a material which cannot pass through gaps between rods of the rod vibrating feeder enters a jaw crusher for coarse crushing, and the material discharged from the jaw crusher enters a first belt conveyor; a material which passes through the gaps between the rods enters the soil removal screen through a second belt conveyor; and the soil removal screen is a double-layer circular vibrating screen, the materials screened and intercepted by a first layer and a second layer enter a secondary crushing surge bin through the first belt conveyor, the secondary crushing surge bin is connected with a first cone crusher through a conveying device, and a discharging chute of the first cone crusher is provided with an electric-hydraulic three-way distributor. The integrated basalt utilization process and device are provided, railway ballast and road surface rubble aggregates can be produced at the same time, and in the production process, the device can be adjusted according to an order at any time to determine whether to produce the railway ballast.

Description

technical field [0001] The invention belongs to non-metallic ore processing, in particular to a basalt comprehensive utilization system and process. Background technique [0002] Basalt is a basic volcanic rock, the main components are silicon dioxide, aluminum oxide, iron oxide, calcium oxide, magnesium oxide (and a small amount of potassium oxide, sodium oxide), among which silicon dioxide has the most content, accounting for about 45%~ 52%. [0003] Basalt has high durability, many joints, and most of the joint surfaces are hexagonal, with a bulk density of 2.9-3.3t / m3, a compressive strength of 100-300MPa, strong weathering resistance, low crushing value, and strong corrosion resistance. It is internationally recognized as the most ideal raw material for railways, airport runways, asphalt pavement, especially SMA high-grade pavement. [0004] The crushing operation of basalt generally adopts the two-stage crushing of "jaw crusher + impact crusher", or the three-stage c...
