The remarkable breakthrough of this mill is the green production. The main materials used to make cement are limestone, fly ash and slag. After crushing, grinding and a series of processes, the raw materials can be made to cement raw materials. And then feed the raw materials into cement kiln for burning, there will produce clinker.
This technology involves pre-crushing the grinding mill feed in roll crushers. Many cement clinker grinding mills receive feed sizes ranging from 80% minus 40 mm down to 20 mm, which Bond and Rowland have shown is very inefficient for ball milling and is much coarser than typical mining single-stage ball mills ranging from 80% passing 6 mm to ...
Green Clinker | Act Improvement No.2 Slag feeding hopper modification Problem: Slag was being dumped by incoming trucks on the floor, then pay loader used for feeding on conveyor. Solution: A ramp was made & hopper size enhanced to accommodate larger volume. Benefits: This system has made the process quicker & now feeding of slag
well as the Cement production. Also the feed materials which are coming from roller press to the ball mill are powdery form instead of Clinker material. The feed chute for this application requires more area to direct the material and more air allowing area to achieve the required air flow inside the mill to transmit the grounded material.
A mathematical model has been developed for an open circuit two-compartment tube mill grinding cement clinker. Samples were collected of the feed and product, and inside the mill. In the laboratory, sizings were done between the top size and 2 μm, and the breakage distribution function of the clinker was obtained by using a twin pendulum ...

Pendulum feeder is often used as the feeder equipment of ball mill collecting mine belt conveyor The mining pendulum feeders are suitable for mineral processing coal preparation chemical industry and other departments It sends granular materials from the storage tank through the hopper to various types of receiving the device. See Details >
The allowable feed size is 900mm and the max. edge length 1200mm. The crushed limestone & Marl size is less than 5% reject at 70mm sieve, adequate for roller mill feeding. The crushing section will also include a low speed short belt conveyor under the crusher designed for 1.5x crusher output to absorb the flow variations.
Clinker Grinding Unit has powder separator, adopts hot air transport materials, the powder and gas enter into powder separator when out of mill. Therefore, Clinker Grinding Unit system has simple technology, low failure rate, high operation efficiency, compact allocation, construction area of 70% of ball mill, construction space of 50-60% of ...
The granulometry and impact energy on the Sharpy pendulum were determined. A 23 factorial type experimental design, dispersion curves and Pareto bars were applied. The controlled variables were type of mill, wet mass and type of bone and the response variables were sieved mass, grinding time, engine revolutions and humidity.
The new PMX demonstrates its strength in a fineness range between 5 and 50 µm (Fig. 5). In this area, the PMX as a pendulum mill system offers a viable alternative to ball mills or even jet mills, thus establishing for the first time an actual option for those two comminution principles. For product fineness between 20 and 50 µm, the PMX ...
As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed.
Mill Feeding Hoppers. Hoppers for clinker/Gypsum/ Additives serve the purpose of providing a buffer storage for mill feed and a convenient arrangement for feeding to weigh feeders for proportioning purpose. Hoppers used to be designed to hold the requirements of one shift. However, for large capacity cement mill it is no longer practical to do so.
The time constant of each pendulum is determined by its mass and the length, and the coupling is determined by the stiffness of the connecting springs. In the ideal case, this system is excited (shifted) by a constant raw feed, and each pendulum moves to a new equilibrium state and remains there. Figure 4.
Such washmills were typically fed with raw materials by tipping whole tram wagon-loads over the side, at such a rate that the mill did not overfill. More modern mills were fed by conveyor belt from feeders delivering a constant flow of materials, often with weighers to meter the components.
Samples were collected of the feed and product, and inside the mill. In the laboratory, sizings were done between the top size and 2 μm, and the breakage distribution function of the clinker was obtained by using a twin pendulum apparatus. Modelling and simulation studies were carried out using the JKSimmet computer programme developed by the ...

The pendulum feeder is also called a pendulum feeder, which is a kind of ore feeding device of the ball mill and an auxiliary device for the transportation machinery. Pendulum feeder is suitable for feeding the granulate materials from the stock chute through the funnel to the material receiving devices with different models in ore dressing ...
Approximately 95% of the feed to the cement grinding circuit are clinker and the rest of the feed are "additives" which includes grinding aids. Cement Manufacturing Process Cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and ...
Kiln feed to clinker ratio is typically 1.65 - 1.75 and, after determination, should be periodically reconciled with clinker and cement inventories and with measured dust loss in the preheater exhaust. Kiln feed = Clinker + Lol + Bypass dust + Downcomer dust - Coal ash where both bypass dust and downcomer dust are converted to ignited basis.
CM2 is an open circuit ball mill system. The product from CM1 and CM2 are 4700 and 4100 Blaine respectively. To satisfy the strength requirements of the cement, the cement mill feeds for CM1 and CM2 included 68% and 79% clinker, respectively. The remainder of the mill feed mix include additives such as gypsum, limestone and pozzolan.
Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.

The ball mill has two rotating chambers with ceramic balls that grind the clinkers. The clinkers are fed from one side. The mill is heated at various temperatures along the separator. The temperature evaporates the water in the clinker and initiates various chemical reactions within the chambers.
Integral grinding carried out by the combination of a roller press, a separator with desagglomerator stage and an elevator. The below table shows the advantages generated by the introduction of a roller press in a clinker grinding process compared with a ball mill alone. Ball Mill. Roller Press. and ball mill.
