How to efficiently crush granite crusher

Granite Introduction

Granite is a deep-seated intrusive rock with rich colors, not easy to weather, high hardness, wear resistance and compression. In addition to being used as hall floors, architectural decorations, and open-air carving stone, it can also be used to produce railway ballast, sand and gravel aggregates, Machine-made sand, etc., are widely used in roads, railways, bridges, municipal construction, high-rise buildings, airport runways and other fields, and its economic value cannot be ignored.

So how to deal with granite? How can it become high-quality railway ballast, construction aggregates, and machine-made sand? Henan Dewo stone crusher machine experts design granite crushing production lines with different forms and high efficiency and economy through in-depth analysis of granite composition and combining with building material standards. Next, I will introduce the relevant processing equipment, technological process and production line characteristics.

Granite crushing production line

 

Different types of crushing production lines are designed for Henan Dewo stone crusher machine according to different uses of granite.

If it is used as a railway ballast or pavement foundation stone, only one-stage crushing is required to meet the material standard;

When used as aggregate for construction, secondary crushing is mostly used;

If it is sand making, a three-stage crushing method must be used. The processing equipment required for each different purpose is as follows:

1. Railway ballast: vibrating feeder + jaw crusher + circular vibrating screen + belt conveyor + electronic control system;

2. Building aggregate: vibrating feeder + jaw crusher + impact crusher + circular vibrating screen + belt conveyor + electronic control system;

3. Machine-made sand: vibrating feeder + jaw crusher + impact crusher + circular vibrating screen + sand making machine + belt conveyor + electric control system; (sand washing machine, dust removal equipment, etc. can be freely configured according to needs)

Granite crushing processing technology

First, large pieces of granite are uniformly sent by the vibrating feeder to the jaw crusher for preliminary crushing treatment, and then rationally screened by the circular vibrating screen, and the granite gravel with too large particle size will be sent back to the jaw crusher for re-crushing;

Qualified materials can be used as railway ballast or sent to the impact crusher for further medium and fine crushing. The finely crushed stones will also be screened by the vibrating screen. Similarly, materials that do not meet the requirements are sent back to the impact crusher to continue crushing;

Granite fines that meet the conditions can be used as building aggregates. If sand is required, they will be sent to the sand making machine for shaping and sand making, and finally finished machine-made sand can be obtained. (In addition, if the wet sand is used, a corresponding sand washing machine must be equipped to clean and dehydrate the sand).

Features of Granite Crushing Production Line

Although Henan Dewo stone crusher machine have designed different crushing production lines according to different application fields of granite, these production lines have similar advantages and characteristics, and the specific performance is as follows:

1. The production line equipment is reasonably configured, and the space layout is more compact and scientific, which can save about 35% of the floor area, and then reduce the infrastructure investment by more than 100,000 yuan;

2. Appropriate selection of equipment, long service life of the production line, and stable operation. The maintenance volume and the replacement rate of wearing parts can be reduced to a smaller value, which can reasonably control the cost and maximize the profit of the investment enterprise;

3. After crushing, the materials can meet the material standards in various fields. The finished materials have beautiful grains, diverse specifications, uniform particle sizes, and adjustable sizes, and the crushing and sand making effects are very significant;

4. The operation process of the production line consumes less energy, has no dust, no noise, and will not affect the surrounding environment. The annual electricity and oil costs saved reach about 120,000 yuan;

5. The crushing production line has less investment, because its design is reasonable, and all equipment is equipped by our company, the quality is reliable, the price is fair, and the total investment is reduced by 70,000 yuan;
