Applicable materials: High weir classifiers are suitable for grading, desliming and dehydration operations in the grinding circuit of gold ore, iron ore, copper ore and other materials.

PRODUCT INTRODUCTION

The high weir classifier is a common equipment in the grinding cycle. It is usually combined with a ball mill to divert ore in a closed circuit, or it is used to classify the size of the pulp in the metal beneficiation process，it is suitable for coarse-grained classification, and has the advantages of stable operation and adjustable classification granularity.

Scope of application: High weir classifiers are widely used in mineral sorting links in various fields such as metallurgy, mineral processing, and chemical industry.
Internal Structure: It is mainly composed of grooves, spirals, deceleration and transmission devices, enhanced devices, ore exhaust valves and other components.

Advantages

1、Controllable granularity: By adjusting the height of the weir (the height of the liquid level of the ore slurry), the particle size of the classification can be adjusted to effectively prevent excessively large particles and sieve residues in the product.
2、High output and low consumption: Frequency conversion control technology, high degree of automation, under the same processing capacity, the energy consumption is 50% lower than other classification equipment, and the output is 50% higher under the same energy consumption.
3、Low maintenance rate: Cancel the configuration of the big spoon head of the ball mill, reduce the maintenance rate and slow down the unbalanced impact on the large and small gears of the ball mill.
4、High quality parts: The base of the machine is made of channel steel, and the body is welded with steel plates, which is wear-resistant and durable, and can be configured with a special hierarchical structure according to different special requirements.

WORKING PRINCIPLE

Based on the principle that the solid particles have different sizes and specific gravity, so the sedimentation speed in the liquid is different, do grading work.
