Rotary Cooler

Brief Introduction to Rotary Cooler

Rotary cooler or rotary drum cooler is one of the important machines in rotary machine. Rotary cooler is used to make the materials (1000-1200℃)which out of the rotary kiln make fully heat transfer with air by rotating the drum to cool the material down to 200℃ and improve the quality and durability of material. What's more, the air which has cooled the material will into the kiln to make air cycling again to improve the thermal efficiency of the kiln.

Characteristics of Rotary Cooler

Rotary drum cooler is one of the important machines in rotary machine. The following are its characteristics:
1. The materials (1000-1200℃) which out of the rotary kiln make fully heat transfer with air by rotating the drum to cool the material down to 200℃ and improve the quality and durability of material.

Rotary Kiln/China Rotary Kiln/Best Rotary Kiln

Brief Introduction to Rotary Kiln

Rotary kiln is also known as calcining kiln, belonging to building material equipment. According to the difference of processed material, rotary kiln can be classified into cement rotary kiln, metallurgy chemical kiln, and lime rotary kiln. Cement kiln is mainly used to roast cement clinker and can be classified into dry-type cement kiln and wet-type cement kiln.

Classification of Rotary Kiln

Metallurgy chemical kiln is mainly used for magnetizing roast in metallurgy industry, iron and steel plant and lean iron ore; oxidizing roasting for chromium, nickel and iron ore; roasting high alumina bauxite ore in refractory material factory; roasting clinker and aluminium hydroxide in aluminium factory; and roasting chrome ore in chemical factory. Lime kiln is used for roasting active lime and light roasting dolomite for steel factory and ferroalloy works.

Application of Rotary Kiln in Metal Industry

Rotary kiln is used in non ferrous and black metallurgy to roast Iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, file and other metals. In addition, rotary kiln is used to roast the ore, concentrate and tertium quid.

Cement Mill/New Type Cement Mill/Low Price Cement Mill

Brief Introduction to Cement Mill

As the cement mill has the similar working principle with the ball mill, it is also called the cement ball mill. With other names of cement grinder and cement grinding machine, the cement mill owns multiple cabin separating boards which do better in grinding materials into the required particle size.

The cement mill with features of high efficiency, high productivity and low power consumption is usually applied in the circling grinding system. It performs quite well when grinding slag cement. The general production of the cement mill can be raised by 15%-20% with the power consumption dropping 10%.

High fineness and high yield cement mill

The high fineness and high yield cement mill with features of simple workflow and small area of the investment plant is mainly used in the open grinding system. The adoption of the advanced grinding device in the mill structure and the specialized discharging grid plate at the mill bottom will reduce the grinding media size to the greatest extent and improve the grinding efficiency enormously.

Three-drum Dryer/2015 Three-drum Dryer/Three-drum Dryer Price

Application Range:industries of mining, ore beneficiation, construction materials, chemical engineering and metallurgy

Applicable Materials:coal, iron powder, yellow sand, molding sand, slag and coal cinder

Here are images of applicable materials:

Introduction

The three-drum dryer is a contact internal heating conduct dewatering unit. During dewatering process, heat is transmitted from the inner wall of the roller to the external wall, passes through the food materials on the external wall, and then vaporizes the moisture of the materials. It is a continuous drying machine.

The  three-drum dryer is used to dry particle materials with certain humidity like yellow sand used in the dry powder and mortar industry, and many kinds of sands used in the casting industry.

Principle

Materials enter the inner side of the drum through the feeding device to realize current flow drying process, then the materials enter the middle layer of the inner wall through the other end to realize counter current drying process. They are lifted in over and over in the middle layer which advance in two-steps forward and one-step back way. The three-drum dryers absorb heat from both inner drum and middle drum, which extend the drying time and realize the best drying condition. Finally, materials fall into the external layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way. The dried materials move quickly out of the drum under the hot air, while the wet ones remain because of their own weight. Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus finishing the whole drying process.

Features

Three-drum dryer has compact structure and covers a small area which is half of the single drum dryer does. The three-drum dryer works reliably with low energy consumption and high heat efficiency which realizes good material drying effect, simple automation control and few operating staff.

Overview

Introduction

Sand dryer also can be called quartz sand drying machine, river sand dryer or sand rotary dryer, is mainly used for drying particle materials with certain humidity, such as all kinds of sand in foundry industry and dry-mixed mortar industry.Clay with small particle size in building materials and cement industry.Small particle size materials with no chemical changes and heat and dust resistance in chemical industry. According to different requirements on moisture content of dried materials in different industries, moisture content of dried materials can be lower than 0.5%.

Sand dryer is mainly applied to drying river sand, dry-mixed mortar, yellow sand, cement clinker, clay, coal gangue, mixtures, coal ash, gypsum, iron powder and other raw materials, widely used in building materials, chemical industry, casting industry and other industries.

Features

1. Accessories of the sand dryer are wear resistant, with high thermal efficiency.
