The sand making machine is a new type of brick making equipment designed and manufactured in accordance with the similar characteristics and market needs at home and abroad.In 1970s, our country introduced the eight-hole sand making machine abroad.It uses river sand and a small amount of fly ash and cement to suppress lime sand bricks.However, the rotation of the disc can only press one piece of brick at a time, and the output is low.

When the large amount of industrial waste fly ash is used, there is a stratification phenomenon in the lack of exhaust. It cannot meet the requirements of the national wall reform and not meet the national industrial policy at that time.In order to improve the output and make up for the disadvantage of easy delamination of the defective products, the domestic mechanical engineers have developed a crankshaft type double crank mechanical pressing machine with two blocks, three blocks or even four blocks.

Because of its special pre pressure buffer design and the adjustment of the depth of the material, it can be qualified for the national policy of industrial structure of the new wall material with large amount of fly ash as raw material.The equipment inherits the eight-hole turntable type brick press without the need of the bracket, the advantages of the direct palletizing, and the stability and reliability of the mechanical motion, and 15~17 times a minute to ensure the production and quality of the single equipment.

The ceramic material is ground to a specified particle size in aindustrial Raymond mill apparatus as a result of the impact of the mill body on impact collision and grinding. However, the grinding process of the ceramic raw material in the barrel of the Raymond mill for limestone is very complicated.

If a single material particle is used as a research object, it may repeatedly receive the impact collision stress and the grinding extrusion stress during the grinding process of the Raymond mill. This causes the existing or newly formed cracks present on the surface of the material particles to expand, thereby forcing the material to plastically deform or break.

When the material particles are continuously ground and crushed by a industrial Raymond mill, it is difficult to further grind a certain level of new particles. The main reason is that the cracks on the surface of the newly formed material particles are fine, and the minimum crushing stress required for the expansion of this fine crack is sharply increased. Even if the final crushing stress required to grind the finely divided ceramic raw material in the ceramic Raymond mill may increase to force the particles to plastically deform, it is not enough to crush the material, that is, the material particles are no longer finely ground and have been ground too fine.

Limestone grinding mill is an indispensable grinding equipment for mineral processing in mines. It is mainly used for grinding crushed materials. The limestone mill has a horizontal rotary cylinder, which contains grinding bodies (iron limestones, ceramic limestones, pebbles, etc.) and materials. 

Because of the rotation of the cylinder, the abrasive body is close to the cylinder wall under the action of centrifugal force and friction, and rotates with the cylinder. When it is brought to a certain height, it falls to the material and smashes the material due to its own gravity. At the same time, because the grinding body rotates along the axis of the cylinder and slides along the inner wall of the cylinder, the material can be crushed. 

This is the working condition of the limestone mill, so how to make the limestone mill more efficient? This is inseparable from the cylinder of the limestone mill and its working parts. 

The newly installed jaw plate must be fixed tightly, installed well, and the surface of the jaw crusher contacts smoothly. A layer of material with good plasticity can be padded between the jaw plate and the surface of the jaw crusher. Every batch of materials entering the crusher should be sampled and checked. Once there is a great change in the nature of the materials, the parameters of the crusher should be changed in time to match the materials entering the crusher.

We must choose materials with high hardness, wear resistance and strong resistance. Cement enterprises with mine crushing production line technology can exchange the same type of wear jaw plate of mine crushing and cement crushing. The worn jaw plate can be repaired by surfacing.

Another is to pay attention to the working process: after the crusher is in normal operation, it can start feeding; The crushed materials should be evenly added into the crushing chamber, and side feeding or stacking feeding should be avoided to prevent unilateral overloading. Under normal conditions, the temperature rise of the bearing does not exceed 35 ℃, and the maximum temperature does not exceed 70 ℃.

If the temperature exceeds 70 ℃, the jaw crusher should stop immediately and the cause should be found out to eliminate. Before shutdown, the feeding should be stopped first, and the motor can be shut down only after the crushed material is completely discharged from the crushing chamber. When crushing, if the material in the crushing chamber is blocked and stops, the motor should be shut down immediately, and the material must be cleared before starting again. After one end of the gear plate is worn out, it can be used with adjustable head.

1. High efficiency jaw crusher has added hydraulic lifting device in the whole system, making the maintenance of equipment more convenient.

2. Jaw crusher can control product grain level by optimizing multiple variables. For example, change the rotor speed of sand making machine; Using different annular crushing cavity; Adjust waterfall flow; The adjustment of finished particle size is realized by means of rotor with different diameter.

3. Because of low maintenance requirements and easy operation, the impact sand making machine can be easily and quickly matched with existing or planned crushing equipment.

4. The jaw crusher is simple and quick to install. The crusher only needs a few supporting structures and is an ideal mobile device.

5. Be able to control product grain size, so as to maximize or minimize fine material production.

6. Capable of producing products of high grade cubes.

7. Excellent single particle dissociation characteristics of jaw crusher to improve mineral recovery.

8. Selective crushing.

9. Various models can be used for any fine crushing.

The barite mill is short for counter-roll crusher. The barite mill has the advantages of reliable operation, simple maintenance, low operation cost and adjustable size of discharging material. According to the number of rolls, it can be divided into two-roll crusher and four-roll crusher.

The tooth shape, size and arrangement on the roll surface can be changed with the nature of the material. It can crush medium-hard and soft ores. For example, in sulphuric acid plant, the barite millis usually used to crush pyrite once, so that the diameter of pyrite can reach 20-30 mm, and then enter the double-roll crusher for secondary crushing, so that the ore diameter can reach.

Under 5 mm, it meets the requirement of fluidized bed furnace. It can be widely used in the processing of brittle and tough materials in cement, metallurgy, chemical industry, electric power, coal and other industries.

Mobile jaw crusher is suitable for crushing medium hardness materials such as limestone, slag, coke, coal and other materials in cement, chemical industry, power, metallurgy, building materials and other industrial sectors.

The mobile jaw crusher is mainly composed of rollers, roller support bearings, compaction and adjustment devices and driving devices. Next, I briefly introduce several aspects that need attention in the operation of mobile jaw crusher.

First: Preparation

• 1. Check whether the parts are complete and intact.
• 2. Check whether the safety device, lighting and signal are in good condition.
• 3. Check whether the amount of oil injected is enough. Fuel quantity should be appropriate, oil quality should be clean, and lubrication should be good.
