Emery Dryer

Emery Dryer Introduction

Drying → Collecting Dust → Screening

Drying: Through disk feeder and wet sand belt conveyor, feed wet sand from moist-material bin to rotary dryer for drying, heated by gas combustion chamber.

Collecting Dust: The dust producing in the process of drying will be collected by dust removal system and cyclone dust collector, fall down to the dry sand belt conveyor. The dry sand will be delivered to the linear vibrating screen for screening.

Screening: The dry sand conveyed by dry sand bet conveyor is screened into different size of sand according to customer’s requires.

Emery Dryer Machine Technological Process

1. Materials is sent into stock bin by belt conveyor or bucket elevator, then conveyed from material silo to belt conveyor by disk feeder, belt conveyor carry materials into feed pipe. The gradient of newest energy-saving feed pipe must be larger than materials’ angle of crater in order that materials flow into dryer successfully.

2. The drum of dryer is a rotary drum which is slightly at an angle with the horizontal line. Materials get in dryer from one side, heat carrier follows at the same time. Through the inner cylinder, middle cylinder, outer cylinder, arrive at discharging port, finally get into discharging silo.

3. After heat carrier goes through dryer, materials carried in heat need cyclone dust collector to capture down. If a need to further reduce the dust content, it should go through bag filter or wet dust collector before discharging.

4. Finally linear vibrating screen separates the qualified finished products from the dried material.

Emery Rotary Dryer Working principle

Triple Pass Rotary Dryer has 3 drying zones in the 3 cylinders (internal one, middle one and external one) which construct the rotating body. Heat processing of a product with high moisture content is done efficiently in those 3 drying zones. The product is put in from the inlet of the hopper, sent to the internal cylinder where heating of the product is evaporation of moisture is promoted further. The solid constituent of the product is gradually broken into piecesand discharged from the outlet via the third final drying zone. The hot air produced in the furnace is sent to the internal cylinder, passes through the middle and external cylinders. The hot air is then sent to the cyclone where dust is removed.
