Hammer mill crusher Application Hammer mill crusher is suitable for mid-hard and light erosive Materials, whose pressureresistance strength is no more than 100Mpa and humidity lower than 15%, suchas coal, salt, chalk, gypsum, blocks, lime Stone, etc. Hammer mill crusher Operating Principle The main working part of hammer crusher is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw Materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammerto small size. There is a screening plate under the rotor, so that Materials with size smaller than the screen mesh will be screened out and others are left tobe further hammered and ground until reach the st and ard size. The size of the final product can be adjusted by changing the screening plate. The gap between therotors and the screening plate can also be adjusted according to different requirement. Hammer Mill Design The major components of hammer mill, shown in the picture, include: - a delivery device is used to introduce the material to be ground into the path of the hammers. A rotor comprised of a series of machined disks mounted on the horizontal shaft performs this task. - free-swinging hammer that is suspended from rods running parallel to the shaft and through the rotor disks. The hammer carries out the function of smashing the ingredients in order to reduce their particle size. - a perforated screen and either gravity- or air-assisted removal of ground product. Acts to screen the particle size of the hammer mill to ensure particles meet a specified maximum mesh size. Feeder Design Materials are introduced into the paths of the hammers by a variable speed vein feeder. This type of feeder can have its motor slaved by a programmable controller to the main drive motor of the hammer mill. The operational speed of the feeder is controlled to maintain optimum amperage loading of the main motor. Screen Design The amount of open area in hammer mills screen determines the particle size and grinding efficiency. The screen must be designed to maintain its integrity and provide the greatest amount of open area. Screen openings (holes) that are aligned in a 60-degree staggered pattern optimize open area while maintaining screen strength. This method will result in a 40 percent open area using 3.2 mm (1/8 inch) holes aligned on 4.8 mm (3/16 inch) centers. Read more: evelyn@cncharcoalmachine.com
PC Hammer Crusher >> Hammer headwork adopt new technology casting, with wear and impact resistance >> Adjusting grain size to meet customers' need >> Seal body structure solved the problems of crushing plant dust pollution and gray body leakage >> The overall design has attractive appearance, compact structure, less easy damaged parts, easy maintainance. The products are upgraded. Description Hammer crusher is a crushing equipment which utilizes impact energy to crush materials . As a primary crusher, the hammer crusher could crush materials directly from maximum 600-1800mm to 25mm and below. It is suitable for crushing all materials of brittle, medium hardness, and compressive strength less than 150Mpa. So the hammer crusher is applicable to crush medium hardness materials in industries of beneficiation, cement, chemical, metallurgy, and so on, such as the secondary and fine crushing of limestone, coal, etc. This equipment can be adjusted to reach various discharged granularity as the customers' requests. Working Principle Hammer crusher mainly consists of frame, rotor, trapezoidal iron plate, bar grate, etc. And the frame consists of the upper part and the lower part. The rotor consists of main shaft, disk,hinge pin and hammers .The bar grate is below the rotor. The motor drives the rotor to rotate at a high speed. When the materials get into the crushing cavity, they are crushed by the rotating hammers, the crushed products which meet the required size can be discharged from the bar grate and become the final products, the products in larger size are brought back for re-crushing until they reach the required size.

Calcined Bauxite: Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 82 % to 86 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 oC to 1600 oC depending upon the customer’s application. We export Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We provide consistency in quality and availability of Calcined Bauxite at extremely competitive prices. Applications of Calcined Bauxite: Refractory Grade Calcined Bauxite (CB - I and CB - II Grade) : To make refractory grade, Bauxite is thermally treated at 1600 oC to produce Calcined Bauxite where the Alumina content is mostly above 82%. Brown Fused Alumina, Proppants and Road Surfacing : To make the above grades, Bauxite is thermally treated at 1000 oC - 1200 oC to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement. Minimum Order Quantity : 1 Containers
