Impact crusher

Impact crusher

Deya Impact crusher with unique blow bar attachment system, it provides a higher degree of reliability. They are designed to minimize maintenance, to improve adjustment operations and to deliver unbeatable performance in primary, secondary, tertiary and concrete recycling applications.

Introduction

Impact crushers from Deya Machinery feature a unique combination of heavy rotor and crushing chamber design in addition to materials selected for their outstanding wear resistance.

This combination has proved revolutionary in improving capacity and product quality while further reducing operating and wear costs.

Working principle

The working principle is mainly by the high speed rotation blow bars to strike the materials, when material falls tangentially on to a rotor, running at 250-500 rpm, receiving a glancing impulse, which sends it spinning towards the impact plates.

The fractured pieces which can pass between the clearances of the rotor and breaker plate enter a second chamber created by another breaker plate, where the clearance is smaller, and then into a third crushing chamber to get qualified products.

Impact crusher gives a much better control of product size because there is less attrition. The product shape is much more easily controlled and energy is saved by the removal of particles once they have reached the size required.

A great advantage in quarrying is in the fact that the impact crusher produces very good cubic products.

Advantages

1. High performance

High capacity

• High reduction ratio

• Less sensitive to sticky material than other machines

• High-quality end product, cubical shape

2. High efficiency

Quick and easy installation

• Easy to operate

• High mechanical reliability

• High machine availability

3. Easy maintenance

Easy blow bar attachment

• Safety devices

• Full hydraulic setting

Features

It can crush ores and rocks with compressive strength of 250MPa.

• Large crushing ratio, close to 20, simplifies the crushing process.

• Low energy consumption, usually about 1kW/t per unit output, which reduces the production cost.

• The product particle size is cubic, with less than 8 % of flakes, which can improve the quality of concrete.

• It has the advantage of selective crushing, and can obtain more sand grade products.

• It has excellent pass iron performance, and the main machine will not be damaged when non-breakable objects enter the crushing cavity.

• Simple and reasonable structure of the whole product, easy to maintain and repair.

• No significant unbalance vibration during working, no need heavy foundations.
