Detailed description

Product overview:

GZL series dry roller granulator is used dry extrusion technology to compress powder materials with water content less than 10% into pieces, and then through crushing, whole grain and screening process, the block material of the sheet becomes the granular material meeting the requirements of use. Dry roller granulation mainly depends on external pressure, which makes the particles forced to pass through two relatively rotating roller clearance, and compress into pieces or various balls. In the rolling process, the actual density of the material can be increased by 1.5-3 times, so as to achieve certain strength requirements.

working principle:

Various dry powder materials are added from the top of the equipment, compressed by degassing and screw top and transported to the arc groove of two rolls. The two rollers rotate at equal speed and reverse direction, and the material is bitten into the groove and forced compression is carried out. The pressure of the material after passing through the compression zone is gradually reduced. The surface tension and gravity make it naturally detached, and then it enters the crusher and the whole granulator for crushing and finishing, and then into vibration The moving screen is screened, and the qualified products are sent to the finished product bin or directly packed through the conveyor. The particles under the powder screen are sent back to the raw material bin again through the feeding device for secondary rolling. The size of extrusion pressure can be adjusted by hydraulic system according to the needs of particle strength. Through the groove form of modified roller surface, the material such as sheet, strip, olive, pillow shape and so on can be obtained.

Technical parameter table:

Note: the output of finished products is based on potassium sulfate particles, and the output of different materials is different.

Product features:

1. The material is forced to be compressed and formed under mechanical pressure, without any additives, and the purity of the product is guaranteed.

2. Dry powder is directly granulated, which is not necessary for subsequent drying process, which is more conducive to the connection and transformation of the existing production process.

3. The particle strength is high, and the increase of the bulk proportion is more significant than other granulation methods.

4. It can be adjusted freely according to different materials.

5. The structure is compact, maintenance is convenient, operation is simple, process flow is short, energy consumption is low, efficiency is high, and failure rate is low.

6. It can control environmental pollution, reduce waste of powder and packaging cost, and improve the transportation capacity of products.

7. The feeding and feeding device adopts frequency conversion control, which has high automation, can realize one person and more machine control, and low labor intensity.

8. The main transmission parts are made of high-quality alloy materials, stainless steel materials, titanium materials, chromium and other surface alloys, which greatly improve the wear-resistant, corrosion, high temperature and pressure resistance of the equipment, and make the unit have a long service life.

technological process:

Dry powder is transported into the raw material bin of bucket elevator by screw conveyor, belt conveyor or manual transportation. The raw material powder is sent to vibration transition bin by bucket elevator, and the material is uniformly sent to the frequency conversion vertical spiral feeder by quantitative feeding device, and the material is degassed and pre compressed. The pre compressed material is pressed into the middle of two relatively rotating rollers for pressure production, and is pressed by the bucket elevator The compacted strip material automatically decayed and then enters the crusher, which is broken into particles of uneven size, and then enters the whole granulator for dressing. The finished particles are extruded into the sieve separator through the sieve plate with mesh holes. The finished particles are directly wrapped half through the screening or into the bucket elevator and sent to the finished product bin. The screened powder materials are returned to bucket lifting through the feeding device Lift the raw material bin and compact again to complete a closed cycle.
