14 Jaw crushers… CHETAK JAW Crushers are designed for primary crushing of even hardest rock. Constructed with heavy ribbed M.S. plates, with strong and thick welding joints. Accurately machined & aligned, string bearing housings, very thick, hard and tough adjustable toggle plate, Heat treated, hardened alloy steel main shaft, proper lubrication system, high manganese steel jaw plates, hard facced side plates, impart a long life to the machine. Spring loaded safety tiebar protects Jaw stock against overloading.

15 Jaw crushers using the compression method are suitable for reducing extremely hard and abrasive rock. As a mechanical reduction method, compression should be called for in these circumstances: If the material is hard and tough If the material is abrasive If the material is not sticky When the material will break cubically Jaw crushers…

20 CRUSHERS… Crushing roll Ideal for reducing hard materials, the Rockmaster Single Roll Crusher is of extremely heavy-duty construction. Its rugged design allows continuous service even in the most severe crushing application. Believed to be one of the world's strongest duty single roll crushers, the Rockmaster traditionally provides years of service with minimum maintenance. The Rockmaster Crusher is the ultimate refinement of strength and design, an outgrowth of the original single roll crusher designed and first manufactured in 1894 by McLanahan. ROCKMASTER

21 Crushing roll… Applications Primary reduction of very hard rock, ore, mine refuse, and R.O.M. coal with refuse. Ideal for slabby feeds and wet sticky material. Capacities shown in Tons per Hour

26 Hammer mills…. PRINSIP OPERASI: Secara umum umpan mengalir menuju unit penggilingan. Produk dipukul-pukul dengan menggunakan martil khusus yang bergabung dengan beater rotor dimana akan memperkecil ukuran partikel sampai dengan ukuran yang diinginkan. Ukurannya bisa mencapai 0.8 mm sampai 20 mm. KEISTIMEWAAN: - Terbuat dari baja. - Kapasitasnya besar. - Mudah dan cepat dalam pemasangan saringan dan martil. - Penyerap dari karet dapat mengurangi vibrasi sampai minimum - Magnet dapat dipindahkan ke feed hopper.

31 GRINDERS….. Bowl mills INTRODUCTION TO BOWL MILLS Coal is the one of the most dominating energy source because of its cost, availability and transportability. Pulverized form of coal has made modern steam generating units highly thermal efficient, reliable, safe and able to efficiently use of low-grade coals. It provides coal-air fuel control, flame stability, effective utilization of carbon and thus reduction in cost and flexibility of operation. The efficiency of combustion depends upon efficiency of pulverizing. The machine used for particle size reduction is called pulverizes or mill. In 1919 at combustion Engineering U.S.A., Raymond Mill was developed. The early mills were built with maximum capacity of 6 tons per hour. By 1930 the maximum capability of this mill design had been increased to 15 and then to 25 tons per hour.

32 Grinding mills use one, two or all three of the basic principles of particle size reduction namely impact, attrition and crushing. With respect to speed these machines may be classified as low speed, medium speed and high speed. The characteristics of commonly used pulverizes are shown in the table below SpeedLow 10 to 20 RPM Medium 40 to 70 RPM High 900 TO 1000 RPM TypeBall Tube MillRing Roll Mill Ball and Race Mill Bowl Mill Impact or Hammer Mill Predominant Principle AttritionCrushingImpact Bow mills…

33 Raymond Bowl Mill Coal Pulverizers, nominally rated at a base capacity of 20,000#/hr. on 55 grindability coal pulverized to 70% minus 200 mesh, (capable of grinding down to 90% minus 200 mesh at a lower rating). Mill and exhauster fans are direct driven by 200HP Elliott induction motors, 3/60/2300V., 1800RPM. Mills are equipped with feeder assemblies with motor drives, fan inlet pipes, dampers and regulators. In stock at additional cost are new spare parts inventory of liners, rings and rolls, etc. Bow mills…

34 GRINDERS…. Attrition mills Attrition Mills 48 and 60 The most vital component in processing cellulose, this mill produces the most consistent low-density product while using the largest feedstock and a minimum amount of horsepower. These mills continually outperform the competition in output consistency, plate life, and fiber length.

38 INTRODUCTION Shown here (right) is the Munson CIM-18-SS. The Centrifugal Impact Mill gives controlled particle sizes down to -200 mesh and is used primarily for friable materials. Available in #304 stainless steel, sanitary, abrasive resistant and standard carbon steel design. Disc Attrition Mills are also available for fine grinding applications of more fiberous materials down to -100 mesh in size. Rotating impactor pin/disc assembly for fine and ultra fine particle reduction, declumping applications @ slower speeds. Design efficiency produces high throughput rates per horsepower requirements. Available in 15-100 horsepower drives via multiple V-belt and shave arrangement, direct drive, C-Faced motors. Typical applications: chemicals, foods, resins, powdered metals, spices, sugars and grains, clays,

39 GRINDERS…. Ball mills Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. Metso overflow ball mill sizes range from 5 ft. x 8 ft. with 75 HP to 26 ft. x 41 ft. with 20,000 HP. Normal feed size to a Metso Minerals ball mill is 80% passing 1/4" (6mm or finer) for hard ores and 80% passing 1" (25mm or finer) for soft ores. Product size is typically 35 mesh or finer. Application A ball mill grinds ores and other materials to a typical product size of 35 mesh or finer.

40 GRINDERS…. Conical ball mills Metso Minerals conical ball mills are most efficient when the maximum feed size is less than 2" and iron contamination is not a factor. These mills are sized from 2HP to 450HP for wet grinding and from 2HP to 500HP for dry grinding. Particles of different sizes and densities, when revolved in a cone will classify themselves with the largest pieces at the point of the greatest diameter. The shape of the conical ball mill provides a classifying action within the mill resulting in increased efficiency and lower power consumption
