Diabase crusher
Introduction to Diabase Fragmentation

Diabase is a basic shallow intrusive rock. The main mineral components are pyroxene and basic plagioclase. Basic plagioclase is significantly more self-shaped than pyroxene, often forming a diabase structure, gray-black. Diabase is the finest building material.

Diabase processing technology
Diabase processing usually requires coarse crushing, medium crushing, fine crushing and sand washing steps.
The specific process is: the vibrating feeder will evenly send the diabase to the jaw crusher for coarse crushing. The coarsely crushed diabase is transported by a conveyor to a cone crusher for intermediate crushing, and the medium-sized diabase is processed through a vibrating screen. After screening, the materials that meet the requirements are sent to the sand making machine for fine crushing and sand making, and the materials that do not meet the requirements are returned to the cone crusher to continue crushing. In the sand making machine, the diabase sand that is finely crushed and formed by the sand making machine is cleaned and removed. Clean diabase sand is the finished sand we want to get.

Production advantage
1. Diabase materials with different sizes, hardness, density, and water content can be processed into construction sand of particle size
2. Uniform sand density and high compressive strength
3. The sand produced meets the construction requirements and can improve the construction quality.
4. According to different process requirements, it can be configured with suitable type equipment to exert its ideal performance.
