Product Description

Introduction

Double roll sand making machine is also called double roll crusher. 2PG series of Double sand maker is used for medium and fine crushing of all kinds of medium hard ore and rock in mineral separation, chemical industry, cement, building materials industrial department.

It is used as sand maker in sand making industry and for super fine crushing in particular industry.It is used for medium crushing.

Double roll sand making machine consist of engine body, roller safety spring, etc. Transmission is driven by motor across belt that the rollers are rotating in two directions. Rollers space cn adjust within the prescribed limit to control the discharge size.

Operating principle

There are wedge or gasket of roll sand making machine installed between the two rollers and adjustable bolt installed on the top of the wedge device. When the adjustable bolt pulled up the wedge, the wedge will make the moved roller getting off the fixed roller. The gap between two rollers become bigger, so does the discharge size. On the contrary, the gap become smaller, so does the discharge size. Gasket device can adjust the discharge size trhough increasing and decreasing the gasket numbers or thick and thin. When increasing the gasket, the gap between two rollers become bigger, conversely, the gap and discharge size become smaller.

Features

1.Compact and flat design resulting in a low/flat overall height of the crushing plant.
2.Easy replacement of crushing segments and comb plates.
3.Insensitivity to smeary, ductile, wet and sticky feed materials.
4.Inclination of side walls is adjustable to improve material feed and intake of larger feed lumps.

5.In most cases pre-screening is not necessary, as the fines contained in the final product can smoothly pass through the crushing tools.
6.Low dust burden.
7.Low specific wear rate due to slow circumferential speeds.
8.Minimum quantities of fines in the final product due to low circumferential speed and special.
