Product Overview

The YPF Series sealed disc pulverizer is designed for fine crushing and grinding of medium-hard ores. It is a primary sample-preparation machine for laboratories in metallurgy, geology, mining, building materials, chemicals and related industries. Its fully enclosed, environmentally conscious structure helps contain dust, while the integrated mechanical and electrical design provides compact installation, low noise and uniform grinding performance.

Working Principle

Power is transmitted through a V-belt and pulley to rotate the main shaft. The moving disc rotates relative to the fixed disc, generating compression and grinding forces that reduce the sample.

Feed: Material enters the grinding chamber through the inlet in the upper part of the end cover.

Grinding: The sample passes between the moving and fixed discs, where it is crushed by compression and friction.

Discharge: The ground sample exits through the adjustable gap between the discs and falls into the collection hopper below.

Main assemblies: The machine comprises the body, transmission shaft, main shaft, bearings, moving disc, fixed disc, pulley, adjustment shaft, feed inlet, handwheel and collection hopper.

Key Advantages

Wear-resistant grinding discs

The core grinding discs are forged from high-manganese steel and specially heat-treated for high hardness, wear resistance and impact resistance. Their curved profile distributes grinding force evenly and helps reduce material blockage and buildup.

Precise, controllable particle size

A high-precision graduated adjustment mechanism delivers stable, uniform output. The stated fineness range is 80–200 mesh, supporting repeatable sample preparation and consistent laboratory results.

Simple operation and broad material compatibility

The compact structure requires minimal installation effort. A generous feed opening and practical throughput make the unit suitable for a wide range of brittle and crystalline materials.

Stable, efficient operation

Quality transmission bearings and electrical controls support smooth running, low noise and a low failure rate. The matched drive system enables rapid grinding with efficient energy use.

Flexible application range

Suitable for small-batch laboratory sample preparation, pilot workshops and small production lines.
