Pour the purchased corn into the grid screen, and send it to the cylinder cleaning screen through the scraper conveyor to remove the soft impurities such as large particles, ropes, stones and soil in the raw materials, and then pass the bucket elevator and sent to the silo for storage.
Introduce the soybean meal/bran purchased back to the pig feed factory into the grid screen, and send it to the primary cleaning screen through a scraper conveyor to remove large particles of impurities and twine and other soft impurities in the soybean meal, and then pass it through a bucket elevator, send to soybean meal steel silo for storage.
The granular materials in the silo, soybean meal silo and warehouse are fed into the pulverizer to be crushed after being crushed. The crushing process is a fully enclosed type, and the crushed materials enter the batching silo through the dust settling chamber through the conveying equipment.
Powdered raw materials, trace elements, minerals, etc. temporarily stored in the batching warehouse are sent to the batching scale for measurement through the unloading machine, and the batching is carried out according to the product requirements, and the double-shaft high-efficiency pig feed mixer machine is in a closed state.
After mixing by paddle mixer for pig feed, it enters the buffer hopper and the scraper conveyor sends the materials to the granulation section.
The corn raw material is sent to the pig feed extruder through a closed screw feeder for expansion, and after the expansion is completed, it is cooled and crushed, and then sent to the batching warehouse to participate in the teaching of the batching of the trough material through the closed screw conveyor and bucket elevator;
After mixing, the materials are sent from the pelletizing bin to the pig food pellet maker conditioner through the closed screw feeder. The addition of steam can make the fiber in the feed soft and improve the pelleting effect.
The temperature is generally maintained at about 85°C to keep the maximum water content at 13%～14%, it takes about 3 minutes to stay for tempering and maintaining. The tempered and maintained materials are sent to the pig feed pelletizer machine to press pellets.
The pig feed pellets produced in the pig feed pellet machine is cooled by a cooling air net, and then sorted by a rotary classification screen.
The screening process is a fully enclosed type, and the excessively long grains and powder produced during the granulation process are removed from the the product is separated, and the separated powder is sent to the quality section for re-granulation, and the finished product pellets that meet the product specifications are transported to the finished product bulk warehouse through the conveying equipment.
The finished pig feed pellets products that enter the warehouse are sold in bulk and bags. The large pig feed mill project receiving section, crushing section, mixing section, expansion section, screening section, and bulk section are all equipped with pulse dust collectors, and the piggery feed mill equipment is fully enclosed.
The dust collector used in the large automatic commercial pig feed mill project requires regular cleaning of the ash hopper during the raw material receiving process, and other dust collectors are directly pulsed back to make the materials return to the pig feed production process for use.
The principle of dust removal is to set a number of cloth bags inside to filter the dust in the air and periodically blow compressed air into the filter bag to remove the dust in the filter bag. It has the advantages of high efficiency and large air volume. The dust removal efficiency of the dust collector is greater than 99.9%.
The cyclone dust collector is composed of intake pipe, exhaust pipe, cylinder, cone and ash bucket. The cyclone dust collector has a simple structure. Under normal operating conditions, the centrifugal force acting on the particles is 5 to 2500 times that of gravity.
It is suitable for the removal of non-sticky and non-fibrous dust, mostly used to remove particles above 5μm. The parallel multi-tube cyclone dust collector device also has a dust removal efficiency of 80-85% for 3μm particles. It belongs to Medium-efficiency dust collector.
