Small Size Pre-grinding Mill Introduction

Our company integrates the technology concerning pre-grinding mill at home and abroad and improves the main technical specifications to successfully design and manufacture the YM series of pre-grinding mill. It is designed with a simple vertical structure and features hierarchical crushing, easy operation, low energy consumption and little dust. The pre-grinding mill is designed without sieve plate so the problem of blocking is eliminated. The hammerhead uses a hinge structure making it convenient for replacement. Both the hammerhead and scaleboard are manufactured with highly wear-resistant alloy and feature high strength, high corrosion resistance and long service life.

Small Size Pre-grinding Mill Working Principle

Step with main shaft, bulk disk and roller bracket is driven by motor through reducer. Installed above bracket, roller assembly rotates with main shaft and swings freely meantime, this bring a large centrifugal force, which scatters bulk materials evenly in grinding intermediate layer between central roller and ring. The bulk materials are grinded into powder and fall on the bottom, and then discharged from discharging opening under the effect of synchronously-rotating scraper.

Features of small Size Pre-grinding Mill

1. The granularity of feedstock allowed is large (D≤**0mm).

2. The granularity of discharged product is small (D D*5≤0.9mm). Discharging efficiency is high.

3. It saves more than *5% of electricity.

4. The process flow is easy. The pre-grinding mill occupies little space and saves on civil engineering investment.

5. The resistant part has a long service life.

6. The pre-grinding mill features simple structure, reliable performance, low management, and operating and maintenance costs.
