Product Description

 

Product Description

Our factory is a leading factory of mining equipments who have over 10 years experience in mining field.

Zhongjing has developed and designed a double-roll sand making machine with independent intellectual property rights for many years,it has various specifications and is suitable for medium and fine crushing of ores and rocks with medium hardness and below. It has outstanding performance in the field of sand making and can meet the needs of sand making in many fields such as smelting and mining.
Applicable materials:
podumene, lepidolite, gold ore, copper ore, etc.
Scope of application:
sand and gravel quarries, building materials, metal and non-metal mines and other industries

Working Principle:

There are two kinds of roller crushers, one is roller crusher, the other is teeth roller crusher. Roller crusher used for fine crushing while teeth roller crusher for coarse crushing
1. The roller crusher consists of two extrusion rollers rotating synchronously opposite each other, a fixed roll and a movable roll.
2. The material is fed from the top of the two rollers, and is brought into the roller continuously by the extrusion roller. After the high-pressure action of 50-200MPa, the material is discharged from the machine with the ideal particle size.
3. When the material is bitten by the roll surface, the force of the roller gradually increases, and the maximum pressure can reach 200Mpa. In addition to a certain proportion of powder materials, the discharged material produces a large number of cracks in the interior of the other granular materials, which can greatly reduce the grinding energy consumption in the further grinding process.
