How much do you know the cement equipment? Cement equipment refers to the cement making machines that are applied to the cement manufacturing plant. Before learning the cement equipment, we learn the process of cement manufacturing process first.

In general, we can divide the cement production line into three main steps: raw material preparation of cement, clinker production, and finished cement. Each step has some cement manufacturing machines, such as raw mill, cement crusher, cement mill, cement kiln, cement cooler, cement dryer, cement silo, packing machine, etc.

As we all know, the first step of the cement production line is raw material preparation. Cement crusher is the main equipment of this step. The raw materials are fed into cement crusher by vibratory feeder; the breaking material is transported by the belt conveyor to the impact crusher for further crusher.

There are various types of cement crusher on the market, including jaw crusher, cone crusher, hammer crusher, impact crusher, and etc. AGICO Cement can provide all types of cement crusher. Our cement crusher can fully crush the raw material, reduce feed size into the mill, and increase the reaction of raw material in the following cement manufacturing process, reduce the energy consumption of the whole cement production line.

Cement mill is another necessary cement equipment of the cement plant. After raw material crushing, cement mill plays vital role in the further cement manufacturing process. Cement ball mill, vertical cement mill, and cement roller press are common types of cement grinding plant.

Cement mill has two functions of the cement production line. Firstly, cement mill is used to grind the crushed material into fine size before clinker production. A cement mill is also applied for grinding clinker into finished cement. The cement clinker grinding is the last step of the cement manufacturing process, in this step, cement mill grinds cement clinker, gelatinizing agent and other materials into the required size, which can meet the requirement of cement.

AGICO Cement adopts the advanced internal selection and special compartment device, add the activation device. The grinding tail has a special discharge grate plate, which greatly reduces the size of the grinding media of the grinding bin, greatly improves the grinding efficiency, and achieves the goal of high output and low energy.

Cement kiln is used to make cement clinker, and it is the core equipment of cement production line; usually, apply for dry method cement production. There are two main kinds of cement kiln to manufacture cement clinker. One is the cement rotary kiln, and it is horizontal and can rotate. Rotary kiln is widely applied to the cement clinker production. Another one is vertical and fixed kiln, so it is called as a vertical kiln.

AGICO Cement can manufacture cement rotary kiln with advantages of convenient and reliable operation, stable thermal regulation, and high operation rate. Compared to other rotary kilns on the market, our rotary kiln increase operation rate by 10%, production capacity by 5%-10%, widely apply for cement production line of different countries.

Clinker cooler and dryer are two necessary parts of cement clinker production. The dryer produced by AGICO can apply for various raw materials and easy to adjust. During the operation, the dryer supplies heat stably, ensures the drying quality and cement quality. The cement cooler is also used for clinker production. Using blower blowing cold air, quench the cement clinker that laid on the grate plate, decrease the temperature of clinker from 1200 to 100 and below, the cooling exhaust gas enters into the kiln as secondary air.

In fact, every cement plant requires different cement equipment. Except for the cement equipment we mentioned above, there are many other cement making machines applied for the cement plant. In the real application, as a professional EPC cement plant project provider, AGICO Cement always provides a solution according to clients needs, such as mini cement plant, VSK cement plant. We also provide single cement equipment with high quality and competitive price, welcome to contact!

The hammer crusher is a kind of crushing machine which uses impact energy to crush materials. It is mainly composed of shell, rotor, impact iron, lining plate, and screening strips. The shell is divided into upper and lower parts, which are welded after being cut by the steel plate. There is a high manganese steel lining plate inside the shell, which can be replaced if worn. The spindle is equipped with hammers with regular array distribution, and together with a rotary table and a hammer passing shaft, they compose the rotor. When the motor drives the rotor to rotate, the centrifugal forces cause the hammers to point radially outwards. After the large materials enter the crushing chamber from the feed port, they are smashed by the high-speed moving hammers. The qualified materials are discharged from the gap between the bottom screening strips, and the unqualified materials are left in the crushing chamber and repeatedly hit by the hammer until they can be discharged.

Hammer crusher can be used for medium and fine crushing of barite, limestone, gypsum, terrazzo, coal, slag, and other soft and hard ores. The equipment can also adjust the gap between the screen strips, improve the discharge particle size to meet the need of users.

1. High output capacity and reduction ratio;2. Low power consumption and even product granularity;3. Simple mechanical structure, compact and light;4. Less investment, simple maintenance, and convenient management.

Jaw crushers are used for the crushing of very hard and abrasive raw materials for cement manufacturing. Jaw crusher is a type of earlier crushing equipment, which is still widely used in smelting, building materials, electric power, water conservancy, transportation, and other industrial fields. Jaw crusher is mainly used for crushing all kinds of ores and bulk materials into medium particle size. The maximum compressive strength of the crushed materials is 320MPa.

The working principle of jaw crusher is: motor drives belt and pulley to move the jaw up and down through eccentric shaft; when the jaw rises, the angle between elbow plate and jaw becomes larger, thus pushing the jaw plate closer to the fixed jaw plate, at the same time, the material is crushed; when the jaw goes down, the angle between elbow plate and jaw becomes smaller; the movable jaw plate leaves the fixed jaw plate under the action of tension rod and spring, at which time the crushed material is discharged from the lower opening of the crushing chamber. With the continuous rotation of the electric motor, the jaw makes a periodic movement to crush and discharge materials, realizing mass production.

Impact crusher is best suited for crushing hard and medium-hard materials with natural cleavage planes. It is widely used in the industry of metallurgy, cement manufacturing, chemical, engineering, etc.

When the feed material enters into the crushing chamber of the impact crusher and collides with the impactor bars installed on the rotor, which is revolving at high speed. The feed material is broken under the high-speed impact, its fragments are hit back by the breaker plate and broken again until they are sufficiently reduced to the proper size to pass through the gap between the two breaker plates. Adjusting the gap between the breaker plates and the rotor frame can change the size and shape of the material.

The cone crusher is also called gyratory crusher, it is mainly used for crushing medium-hard to hard raw materials. In the working process of the cone crusher, the motor drives the eccentric sleeve to rotate through the transmission device, so that the inner crushing cone oscillates under the drive of the eccentric sleeve. The feed material is compressed and crushed by the fixed conical bowl and the oscillating crushing cone head. The material crushed into the proper size will fall and be discharged from the bottom of the machine.
