Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. Ball Mill Application: are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills. Ball mill is an efficient tool for grinding many materials into fine powder. The ball mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.

Motor connected to gearbox via a V-belt drive. - Product discharge via slots located around the periphery of the drum. Ball mill Working Principle: The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished. Standard export container or as your required.

Nowadays, Carbon black is widely used rubber industry as reinforcing agents and fillers. What¡¯s more, it is one of the oldest industrial raw materials. China is the head of the world¡¯s 12 largest producers of carbon black, with the rubber market rebounding from the economic crisis, China carbon black market has had great demand, and carbon black mill also faced unprecedented growth of gold. According to forecast, world carbon black consumption will reach 11.5 million tons in 2015. Progress will come from Asia, particularly the pulling powder of China, India, and Indonesia and Thailand. Notch Consulting Group forecasts, China¡¯s demand for carbon black will reach to totally 3.7 million tons in 2015. With radial tire production increases, carbon black is expanding in all areas of the Chinese market. Because of the thriving carbon black market, demand of carbon black mill is also increasing. Shanghai Clirik Co., Ltd is specialized in manufacturing Carbon black ultrafine mill, because technical innovation, excellent quality, and good service, Clirik is known as ¡°expert of carbon black grinding mill¡±. Working principle of carbon black grinding mill: Clirik calcite grinding mill mainly consists of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder. After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, edge of then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe.When the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the air flow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall an exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end. Features of carbon black grinding mill: 1. High efficiency Under the same finished final size and the same motor power, the capacity of micro powder grinding mill is twice as much as jet mill, mixing grinder and ball mill. 2. Long lifecycle of spare parts The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate. 3. High safety and reliability As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components. 4. High fineness and flexible adjustment The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97¨Q5um. 5. Environment-friendly The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
