4 common crushing schemes in stone production line

Rock crushing is the technology and theory of separating part of the rock mass from the parent body and breaking into rock blocks in mining operations. There are usually four methods for rock crushing in the stone production line, which are described below.

1. The water jet flow crushing method is divided into two types: low pressure and large flow and high pressure and small flow. The pressure of the former does not exceed 2×107Pa and is mostly used for hydraulic mining or coal mining; the pressure of the latter can reach several hundred million Pa (Pa) and is used to cut rocks. In addition, pulsed jet technology has been developed, which can effectively crush solid rocks without requiring a lot of power. The current instantaneous pressure can be as high as 5.6 GPa.

2. Thermal crushing method, forming a high temperature gradient in the rock body, and using the different thermal expansion coefficients of each component of the rock to form thermal stress, causing the rock mass to peel off or break up. This method is used for rocks with more quartz The effect is better.

3. Explosive crushing method, using explosives or other explosives to release huge energy instantly to crush rocks.

4. Mechanical crushing method, divided into four methods: cutting, punching, rolling, grinding. When breaking the rock, the rock breaking tool sand making machine enters the rock, and a dense verification appears in the rock body before the tool moves. Larger fragments are produced around the dense core.

Each of the four crushing methods has its own advantages and disadvantages. For example, mechanical crushing is easy to cause tool wear, high-pressure water jet crushing rocks consumes high energy, and the mechanical structure is more complicated. At present, the explosive crushing method is widely used in stone production lines and is more effective. Investors can choose the correct crushing method according to their own situation to reduce unnecessary energy consumption and losses.

Limestone Processing

Limestone introduction:

Limestone is an important road building material and an important raw material for calcium carbide and cement.It is a solvent limestone in the metallurgical industry. After superfine grinding, high-quality limestone is widely used in the manufacture of paper, rubber, paint, coating, medicine, cosmetics, feed, sealing, bonding, polishing and other products.The compressive strength of limestone is generally around 150 MPa, which belongs to soft rock. Therefore, the production process of limestone production line adopt the impact crusher.The Dewo limestone production line is equipped with a proven XF impact crusher,this kind of crusher is a high-efficiency impact crusher, which is very suitable for crushing limestone, sandstone and other materials. 95% of the broken products are less than 45mm.

Limestone processing:

Dewo limestone production line equipped with high performance impact crusher,this kind of crusher is a high-efficiency impact crusher, which is very suitable for crushing limestone, sandstone and other materials. 95% of the broken products are less than 45mm.

Firstly, the stone blasted from the mountain is uniformly fed into the jaw crusher through the feeder, and is initially broken.The coarsely crushed semi-finished product is conveyed to the impact crusher through a belt conveyor for further crushing.The crushed stone is conveyed to the vibrating screen through a belt conveyor to separate stones of different specifications.The stones that meet the customer’s particle size requirements are transported to the finished product pile by a belt conveyor.The stones larger than the size of the upper screen are returned to the impact crusher by the belt conveyor and broken again to form a closed loop.

Applications:

Chemical, cement, construction, refractory and other industrial sectors are used for coarse, medium and fine crushing of medium hardness materials.

Equipment configuration:

vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor

Limestone processing technology:

The limestone production line has high crushing efficiency, low power consumption, strong adaptability (especially suitable for medium and hard brittle materials), large crushing ratio, simplified production process and investment saving.

Remarks: The production line is mainly based on the actual material size and the customer’s requirements for product granularity. According to different production site conditions, Dewo engineers can provide customers with process planning and technical support, and we can also design non-standard according to the actual installation conditions of customers and supporting components, etc., we strive to achieve a reasonable and economical production line for customers.

Aggregate For Highway Building

Aggregate for highway building Introduction

In the construction of expressway, high requirements are placed on the aggregate shape and gradation of concrete aggregates, especially the pin-like content in basalt (diabase) gravel. In order to solve the requirements of particle size and gradation, particle shape, consistency of particle composition, cleanliness and particle content of 0.075mm, Dewo has added a new sand making machine in the production line configuration to better meet the highway cement and asphalt. Wait for the requirements of sand and gravel aggregates.

Applicable materials: granite, basalt, diabase and other hard materials

Application areas: highways, urban construction, airport construction and other industries

Equipment configuration: vibrating feeder, jaw crusher, hydraulic cone crusher, circular vibrating screen, vertical shaft impact crusher, belt conveyor

Production line details

In the construction of expressway, high requirements are placed on the aggregate shape and gradation of concrete aggregates, especially the pin-like content in basalt (diabase) gravel. In order to solve the requirements of particle size and gradation, particle shape, consistency of particle composition, cleanliness and particle content of 0.075mm, Dewo has added a new sand making machine in the production line configuration to better meet the highway cement and asphalt. Wait for the requirements of sand and gravel aggregates.

Expressway aggregate production process

The mined stone is firstly fed by the vibrating feeder to the jaw crusher for preliminary crushing. The secondary crushing is completed by the cone crusher. The material broken by the cone is sieved on the vibrating screen. The material larger than 40mm is returned to the cone and broken again. A closed loop is formed, and the material less than 40 mm enters the vertical impact to break and shape. The finished product sieved by the vertical impact material is sieved, and the returning vertical impact breaking cycle of more than 20 mm is broken, and the materials less than 20 mm are conveyed to the respective finished material piles by the belt conveyor.

Expressway aggregate production line performance

1. The sandstone production line is highly automated;

2. It has high production efficiency, low operating cost, large output and high profit;

3. The size of the discharge material is adjustable, the breaking rate is high, and energy saving;

4. The finished stone has uniform particle size and good granular shape, which is in line with the national high-speed material standard.
