Transportation and Installation

1. Hoisting
It can be seen from the following picture how the mixing machine is hoisted by a traveling crane. The rope must be capable of bearing the weight of equipment, and too short a rope is not usable. The lifting ears for hoisting are provided.


2. Transportation
When the mixing machinery is to be delivered out of the manufacturer’s plant, it can be decided according to the practical conditions whether a packing case should be used or not. If the packing case is not used, rainproof facilities should be provided and it is necessary to prevent the equipment from collision and overturning.
If the packing case is used, the whole machine and accessories should be firmly fixed inside the case, and a certain distance between the machine and the walls of the case should be maintained to avoid collision or damage during transportation. If the equipment exceeds the height limit, it should be packed in parts.

3. Storage
When the paddle mixer is to be stored for a long time, it is necessary to put it in a ventilated, dry, shady and cool place with rainproof and damp-proof facilities. The exposed surfaces without paint should be coated by antirust oil.

Muyang SFSC Series Grinding Machine

This grinding machine is a structure of welded steel plate, the motor and the crusher rotor are installed on the same base, directly driven by an elastic pin coupling; the rotor is calibrated by dynamic balance, it can rotate both co rotation and reversion, so as to prolong the service life of wearing parts. The operation gate is equipped with a safety interlock device to ensure that the motor cannot be started while the operating gate is open. The feeding inlet is located at the top of the crusher and can be matched with different feeding mechanisms. The hammers are arranged symmetrically.

The raw material on the SFSC Series grinding machinery to be crushed (ground) is fed from the feeding inlet at the top by means of a feeding mechanism, which is matched with the machine, and enters the crushing chamber through the feeding guide plate from the left or right, then ground gradually by the beating of the high-speed hammers and the friction of the sieve plates, and discharged from the outlet on the base through sieve apertures by centrifugal force and airflow.


Muyang grinding machines are all in high technologies with full function, and every part on the machine is designed carefully and strictly.

Base: for connecting and supporting each part of the crusher and making them integrated. The crushed material is discharged from the base.

Upper housing: the upper part is completed with a feeding inlet and the lower part is linked with the base. Both sides are equipped with sieve plates, and the crushing chamber is formed by the sieve plates together with the rotor and the raw material is crushed in such chamber.

Rotor: composed of main shafts, hammer carrier plates, pins, hammers and bearings, which are the major moving parts of the crusher. The rotor rotates in high speed, and a dynamic balance calibration shall be conducted after assembling but without pins and hammers.

Operation gate: It is necessary to start the operation gate when replacing sieve plates or hammers. The sieve plates are held down by the operation gate.

Feeding guide mechanism: guide the materials to enter the crushing chamber from the left or right. The feeding guide plate is reversed by control of the cylinder with an electric controlled valve and the motor rotation direction is changed automatically by a limit switch to make it comply with the feeding direction, to ensure a tangential feeding.

Heat Insulation Measures on Silo

At present, in order to implement related policies of energy saving, environmental protection, energy utilization efficiency, our construction industry has built external walls for insulation works. Now silos that have been built should be improved on walls in accordance with the heat insulation; meanwhile, the new grain silo must implement heat insulation measures.

The measures for heat insulation on steel silo are: Construct insulation works on the inner and outer surface. The outer surface and an inner surface of the insulation engineering collectively ensure internal and external insulation works. Wall surface insulation works created in Europe has a history of over 35 years, and the most used system is thin plaster EPS board insulation. In the mid-1980s, China external wall insulation has been a pilot project. The first project is the EPS board for thin plaster exterior insulation system. Because external wall insulation in building energy efficiency and indoor environmental has many merits, and now urban and rural housing construction has made external insulation as a key project.

Insulation system of wall surface is a system which consists of insulating layer, protective layer and fixing materials.

External wall insulation works can form building through a process of combination of external wall insulation systems, assembly and construction. Construction on storage silo now currently use EPS thin plaster external wall insulation system consisting of EPS board insulation layer, a thin layer of plaster and paint finishes layer; EPS plate fixes with adhesive on the base, thin plaster layer is covered with fiberglass mesh, light-colored plaster surfaces do all kinds of decorative paint or paste cylinder brick layers, tile surface layer, the surface layer of mosaics, marble surface layer.

Fireproof Design on Grain Silo

The area on bulk food warehouse shall not exceed the maximum allowable area of 12,000 square meters; the maximum allowable area for each firewall should not exceed 3,000 square meters.

Steel silo and squat silo can be arranged into groups, and total reserves of each group separately were ≤ 40000 ton, 40001-50000 t, 50001 -100,000 ton; while squat silo total reserves of each group were ≤ 50000 t, 50001-1500,000 tons.

Steel or semi-steel bulk food banks on each side of the firewall WAREHOUSE within 6 m of columns, beams, roof load-bearing structural components and building envelope fire protection measures should be taken to its fire resistance, and fire resistance should follow the "architectural design code for fire protection." 2.0.1 Requirement.


Storage silo, squat silo, underground corridor, transit warehouse, and working tower should be taken in accordance with the relevant specification explosion-proof measures.

When the total reserves on silos is more than 40,000 tons, its outdoor fire water should not be less than 45 liters / sec; when the volume of the warehouse is greater than 50,000 cubic meters, its outdoor fire water should not be less than 45 liters / sec. Squat silo’s underground corridor should set water spray system.

When the fire load of the power supply does not meet the two-level above requirements, you can be use the internal combustion engine driven fire pump.

Other fire structure of the grain silo should be designed in accordance with the architectural design of fire protection regulations.

Basic Information on Grain Silo

The bottom bears the whole grain silo, and the main structure of the silo forms to the square steel, and angle steel. Because of the large cabin, in order to transport easily, we divide the silo bottom into four sections and each angle iron and bolt are connected, which can be removed easily.

Good ventilation can not only reduce the moisture in the food, but also reduce the temperature, in order that the grains can reach industrial production indicators. Therefore, the ventilation design is a key matter. The grain silo we designed is good for natural ventilation, which has a round vents in the top storage silo, making air exchange.

The research has shown that in the low temperature, coming from summer to autumn, the silo should keep two or three ventilations, which can last many nights with four to ten hours every time. While, in winter, the silo’s temperature can keep the same, until to spring, the temperature can raise. The practice has indicated that using the best steel silo, the quality of the food still keep great as before.


The design requirements in different areas:
1. In the main ports, transportation hubs, major railway construction and other food distribution centers, in order to use higher levels of mechanization, we prefer to choose squat silo and steel silo, supplemented by large span warehouse.

2. The grain silo which should connect with the World Bank can be as a silo that is suitable for bulk grain storage.

3. The Northeast and North China may have more choices of steel silos, in order to accelerate the progress of construction. The main rice producing in the south should be mainly used warehouse or reinforced concrete squat silos.

4. Creating a new silo is mainly based on external conditions on whether it can allow bulk warehouse-type, while in the design, we should allow the implementation of "scattered" , and the expansion project should be chose based on the original position and layout.
