Product Description

Gypsum Powder Production Lion

Production process introduction

The crusher breaks large gypsum rock into small particles of less than 25 mm in diameter, the particles go through storage and transportation equipments into the mill for grinding, use a powder concentrator to select qualified gypsum powder of required fineness and send them into the boiling furnace for calcination. The left unqualified particles will return to the mill for regrinding until meet the requirement. Calcined qualified gypsum powder will be send into the clinker silo for storage or to the workshop for use.

Technological Process

The system has high automation degree, convenient control, and can monitor the speed, temperature, humidity and equipment running status at any time, so as to effectively reduce the labor, cost and improve the efficiency. It is the preferred typical equipment in modern building materials industry.

Boiling furnace technology introduction

1. Working principle

The main body of boiling furnace is mainly composed of intensive small diameter radiator coil tubes. Replenish heat conductive oil into the coil tube, and by heat transfer to release heat into the furnace body. Install roots blower at the bottom of the boiling furnace, blow the cold air into the furnace body with air distributor, and blow powder materials inside of the furnace body to make it reach the boiling state. At a certain temperature, the powder materials drained of crystal water after drying become lighter and automatically flow to the discharging entrance.

2. Features of the boiling furnace

♦Simple structure, not easy to be damaged

♦ Compact equipment, small occupation of land

♦ Low energy consumption

♦ Good product quality, ideal phase composition of calcined gypsum, stable physical properties.
