Applications:
LM sand powder vertical mill is a kind of ultra-fine sand making and powder grinding equipment, which is mainly suitable for the prefabricated sand powder process before the crushing of mineral products such as metallurgy, building materials, chemicals, and mines. It is specially used for the preparation of special mortar fine aggregates. The finished sand powder of each grade can be prepared.
Capacity: 30-900T/H
Input size: <55mm
Performance Advantages
Sand and powder are produced at the same time, one machine has multiple uses Ultra-fine sand making and grinding equipment can prepare finished sand powder of various gradations.
It has a number of independent patent technologies and intellectual property rights, the main technical and economic indicators have reached the international advanced level.
The gradation of finished sand powder is adjustable and controllable, and the product has high added value.
High production efficiency, low operating cost, simple operation, convenient maintenance, energy saving and environmental protection.
It solves the industry pain points of low yield and high energy consumption of conventional sand making equipment, and realizes the ideal preparation of high-quality graded sand for special mortar.
The system is simple, the layout is compact, and the footprint is small.
Working Principle
The main motor drives the grinding disc to rotate through the reducer, and the material falls from the feeding port to the center of the grinding disc. Under the action of centrifugal force, the material moves uniformly from the center of the grinding disc to the edge and passes through the crushing roller area on the grinding disc, and is crushed by the grinding roller. The bulk material is directly crushed, and the fine-grained material is squeezed to form a material bed for intergranular crushing. The crushed material continues to move towards the edge of the grinding disc until it is thrown out of the grinding disc by the centrifugal force of the grinding disc, falls to the lower chamber of the mill, and is scraped into the discharge port by the scraper installed at the bottom of the grinding disc and then outside of the mill. The material is sorted in the external sorting or separation equipment, and the bulk or large particle material that exceeds the particle size of the finished product is recirculated into the mill for re-grinding until it reaches the appropriate particle size.
