DAP Crusher

DAP Crusher

DAP crusher is a kind of adjustable screenless crusher mainly using the gap between the drum and the concave plate to grind and cut the material, the size of the gap determines the degree of material crushing, is one of the most widely used equipment in fertilizer crushing.

Grinding DAP Fertilizer

DAP Crushers are used to grind large DAP crystals into smaller granules, typically ranging from 1 to 3 millimeters in size. This process enhances the surface area of the fertilizer particles, promoting better dissolution in water and improving nutrient uptake by plants.

Crushing DAP Lumps

DAP Crushers are used to break down hardened DAP lumps or agglomerates that may form during storage or transportation. These lumps can hinder the even distribution of fertilizer during application, leading to uneven nutrient distribution and potential crop damage. Crushing these lumps into smaller particles ensures uniform application and optimal nutrient delivery.

Processing DAP Blends

DAP Crushers are often integrated into fertilizer blending processes, where they are used to homogenize mixtures of DAP with other fertilizers or additives. Crushing the components into uniform particle sizes ensures proper mixing and consistent nutrient distribution in the blended fertilizer.

The two main mechanisms of the DAP crusher

  • Impact Crushing: This method utilizes high-speed impact forces to break down DAP crystals. The crusher contains rotating impellers or hammers that strike the DAP material, causing it to shatter into smaller particles.

  • Grinding: This method employs grinding mechanisms, such as rollers, mills, or discs, to grind DAP crystals into smaller particles. The grinding action reduces the size of the particles through friction and abrasion.

Frequently Asked Questions

1. Installation: After the machine arrives at the factory, it will be installed in conjunction with the process, indicating the elevation and horizontal position, tilted installation, generally tilted at 2-5 degrees (which can be adjusted to make the user’s needs), and the machine bracket and transmission frame even ground angle holes, which can be mounted on rolled condensed soil.

① machinery each base and the foundation between the pad into the deed-shaped mat board thickness should not be greater than 30-35mm;

② the height of the base with the deed-shaped pad to adjust the height of the base to make the base 5 degrees of inclination;

③ After each base is adjusted properly, put the cylinder on the support and adjust the carrier wheel;

④ Install the drive part of the film wrapping machine;

⑤ Be sure that the bracket wheel, transmission device and cylinder are properly adjusted and start pouring cement, and after 8-10 days, start the no-load test run after the cement is solidified;

⑥ Method of adjusting the position of the machine body:

a. On the full length of the left and right sides of the machine body, install two parallel steel wires with a diameter of 0.5-1mm and check the level of the wires with a level meter;

b.Lower two phase hammers tangent to the rolling circle from each rolling circle down the sides of the dryer;

c.Measure the distance from the steel wire to the wire drop to detect the body in the horizontal position;

d. Measure the relative vertical elevation of the two rolling circles to check the position of the machine body in the vertical plane;

e. Use the method of moving the electric torque wheel to adjust the measurement of the two articles c and d, so that the machine body is in the correct position;

2. No-load test run:

1). Uninterrupted no-load for 8 hours, the temperature of each bearing should rise smoothly, and the temperature of the bearing should not be higher than 50 degrees Celsius at the termination of the test run;

2). The noise of gears should be average and should not be high or low;

3). After the test run, the bearings shall be observed without serious wear and abrasion.

A.Starting the machine

1. The following preparations should be made before starting the film wrapping machine;

a. Check and adjust the powder feeding device and protection equipment;

b. All bearings and lubricating devices of friction surfaces should have appropriate quantity of grease;

2. It is forbidden to start the film wrapping machine without checking the film wrapping machine and auxiliary mechanical equipment;

3. The steps to start the film wrapping machine are as follows:

a. Start the motor of the film wrapping machine.

b. Start the feeding and discharging conveying equipment.

B. Stopping

1. The steps to stop the film wrapper are as follows:

A. Stop adding raw material to the wrapper;

B. Turn off the drive motor of the wrapping machine;

C. Stop the equipment for transporting granular materials;

1. Dry grease should be smeared at the gears before starting the machine;

2. Dry grease to be smeared on the surface of rolling belt once in 7 days;

3. Bearing housing to be hit or renewed with new dry grease every three months;

4. Add gear oil once before the reducer is used and replace it every four months thereafter;

Pinion gear is worn, install pinion gear upside down, if both sides are worn, new gear is needed.
The intermediate connection between the large gear and the cylinder is damaged, adjust the connection and make appropriate treatment if necessary.

Clamping roller belt to the side of a concave joint

Clamp the belt to the concave joints with pads or wedges, but beware of over-clamping, which can lead to accidents, but uneven tensioning can cause the machine to jump and vibrate.

Wheel wear Refurbish or replace the wheel according to the degree of wear
Block wheel wear Repair, move, or replace with new block wheel depending on degree of wear

Simple body vibration
